Show HN: News-briefing-generator – Local LLM-powered news digest Hey HN, I created a tool to generate personalized news briefings from RSS/Atom feeds using local LLMs through Ollama. It currently works in two modes: fully automatic or with an interactive review where you can select which "main topics of the day" to include in your briefing. The result is a HTML document with summaries for each topic. https://ift.tt/oBmFGK2 March 1, 2025 at 12:15AM

Show HN: Globstar – Open-source static analysis toolkit Hey HN! We’re Jai and Sanket, co-founders of DeepSource (YC W20). We're open-sourcing Globstar ( https://ift.tt/vSItJRT ), a static analysis toolkit that lets you easily write and run custom code quality and security checkers in YAML [1] or Go [2]. After 5+ years of building AST-based static analyzers that process millions of lines of code daily at DeepSource, we kept hearing a common request from customers: "How do we write custom checks specific to our codebase?" AppSec and DevOps teams have a lot of learned anti-patterns and security rules they want to enforce across their orgs, and being able to do that without being a static analysis expert, came up as an important want. We initially built an internal framework using tree-sitter [3] for our proprietary infrastructure-as-code analyzers, which enabled us to rapidly create new checkers. We realized that making the framework open-source could solve this problem for ...

Show HN: Ranked Search for Semi-Structured Data We’ve been working on a search problem that requires querying both text and numbers simultaneously. For example, in a dataset of clothing items with descriptions and prices, a search for “slim pants for $20” should prioritize skinny jeans for $25 over slim pants for $50 because they are semantically similar and the price is closer. I’ve found that standard embedding models struggle with numerical ordering, while text-to-SQL methods rely on exact matches and often filter out too many results. To solve this, we built a system designed specifically for structured datasets like CSVs or tables. Here’s a demo link where you can upload a small CSV to try out (no login required): https://ift.tt/tupvMdf . Unlike most RAG approaches, we process each column independently, handling text with embeddings and numbers with custom scoring. When a user submits a query, we parse it into relevant fields—for instance, extracting “slim pants” as the descriptio...

Show HN: Bild AI (YC W25) – Understands Construction Blueprints Using AI Hi HN! We're Roop and Puneet, the founders of Bild AI ( https://www.bild.ai ). Bild AI uses machine learning to read construction blueprints and extract detailed material quantity and cost estimates. Here's our demo: https://youtu.be/vBDl7Mh7iEc The problem we're tackling is the sheer manual effort that goes into generating material quantities and cost estimates from blueprints today. Contractors and suppliers spend countless hours doing takeoffs by drawing on blueprints by hand - it's tedious, error-prone, and costs the global industry $30B a year. A single mistake can lead to thousands in losses on a project. My co-founder Puneet experienced this firsthand as he was building hundreds of houses in Canada. Meanwhile, my background is in applied ML - I started at Google at 19, then Waymo where I built perception models for self-driving cars. Puneet and I met at Hack for Social Impact where we built ...

Show HN: Superglue – open source API connector that writes its own code Hi HN, we’re Stefan and Adina, and we’re building superglue ( https://superglue.cloud ). superglue allows you to connect to any API/data source and get the data you want in the format you need. It’s an open-source proxy server which sits between you and your target APIs. Thus, you can easily deploy it into your own infra. If you’re spending a lot of time writing code connecting to weird APIs, fumbling with custom fields in foreign language ERPs, mapping JSONs, extracting data from compressed CSVs sitting on FTP servers, and making sure your integrations don’t break when something unexpected comes through, superglue might be for you. Here's how it works: You define your desired data schema and provide basic instructions about an API endpoint (like "get all issues from Jira"). superglue then does the following: - Automatically generates the API configuration by analyzing API docs. - Handles pagination, ...

Show HN: Instantly Translate Manga – TranslateManga Since I was young, I've loved anime, and over the years, manga has brought me joy, given me courage, and sparked excitement in my heart. However, as I read more, I realized that many of these manga weren't translated at all. I also came across some AI-based translation tools, but the results often fell short. So, I decided to create a tool that allows manga fans to read and enjoy their favorite manga, no matter the language or whether a translation team is available. This product has just been launched, and there are certainly areas that can be improved. However, with time, I'm confident it will only get better. You're welcome to try it out and share your valuable feedback! https://ift.tt/hIcHpxq February 24, 2025 at 09:39PM

Show HN: Yaak – An Open Source, Git-Friendly Desktop API Client Hi HN! I'm Greg and I've been working on Yaak for just over a year. I usually describe it as a Postman alternative since most developers are familiar with that, but it's targeted more toward users that just want an API client (no mocking, testing, spec design, etc). Having also created Insomnia for a similar purpose, I never thought I'd build another API client again. But, after selling Insomnia in 2019 and watching it expand into the broader feature set of Postman, I was left wanting a simpler tool again. Yaak was my answer to that. It's hard to describe how it's better than the 100 other API clients, since its main benefit is design, but there are a few stand-out features: - Optionally sync data to a local directory as plain-text, for use with Git/etc - Build and install plugins for authentication, template functions, or generic actions - Support for REST, GraphQL, WebSocket, server sent events, a...

Show HN: Tach – Visualize and Untangle Your Python Codebase Hey everyone! We're Evan and Caelean, and we're the authors of Tach. Tach gives you the tools to build a modular monolith in Python: visibility into the state of your dependencies, as well as the tools to fix them. Since our last Show HN ( https://ift.tt/IFfMuvy ) we've shipped support for layers, third party dependencies, visualizations, and more. Tach is: * Open source (MIT) and completely free * Fast (written in Rust ) * In use by teams at NVIDIA, PostHog, and more As your team and codebase grows, code gets tangled up. This hurts developer velocity, and increases cognitive load for engineers. One way Tach differs from existing systems that handle this problem (build systems, import linters, etc) is in it's ability to be incrementally adopted and its runtime speed. If you struggle with dependencies, onboarding new engineers, or a massive codebase, Tach is for you! We built it with developers in mind - with cl...

Show HN: Bhumi–OSS Python Library w Rust Underhead for 2.5x Faster LLM Inference Read the full blogpost at https://ift.tt/ZyYABoX (click on reader to see the technical breakdown!) AI inference should be fast, but in practice it’s painfully slow. Inference bottlenecks slow down LLM-powered chatbots and AI workflows everywhere. I built Bhumi to fix that. Bhumi is a Python library designed for developers, yet its performance-critical core is implemented in Rust (via PyO3) for near-native speed. This hybrid approach delivers up to 2.5x faster response times across providers like OpenAI, Anthropic, and Gemini—without changing the underlying model. THE PROBLEM: SLOW AI INFERENCE Most LLM clients suffer from three main issues: 1. Batch Processing Overhead – Clients wait for the full response instead of streaming data as it’s ready. 2. Inefficient Buffers – Default buffer sizes aren’t tuned for AI-generated text. 3. Validation Bottlenecks – Tools like Pydantic slow down structured response han...

Show HN: Mapping historical markers around the world I saw the 'map of torii' post yesterday and thought y'all might like to see the small app I've been working on that uses HMDB.org data to map historical markers around the world. HMDB has been aggregating markers for over 15 years and back when I was living out of my van and traveling full-time I wanted to get notified whenever I passed one, so I built a mobile app around that. I think historical markers are underrated - as a physical marker they make history tangible. Rather than reading about history from a classroom, you get the opportunity to see and engage with it at the source. If you're already nearby, they are often worth the stop to learn more. Since releasing the iOS app a few years ago, I've been able to enhance the markers with summaries (which makes reading the content a lot more palatable), and converting them to audio, so you can listen to markers when you're driving. Yesterday I officially ...

Especially with Gemini 2.0 becoming cost competitive with the cloud platforms. We've been continuously evaluating different models since we released the Zerox package last year ( https://ift.tt/vpie3W9 ). And we wanted to put some numbers behind it.

Full writeup + data explorer here: https://ift.tt/bd86ePA Github: https://ift.tt/mHo7iVU Huggingface: https://ift.tt/bSyKseX Couple notes on the methodology: 1. We are using JSON accuracy as our primary metric. The end goal is to evaluate how well each OCR provider can prepare the data for LLM ingestion. 2. This methodology differs from a lot of OCR benchmarks, because it doesn't rely on text similarity. We believe text similarity measurements are heavily biased towards the exact layout of the ground truth text, and penalize correct OC...

Show HN: Mastra – Open-source JS agent framework, by the creators of Gatsby Hi HN, we’re Sam, Shane, and Abhi, and we’re building Mastra ( https://mastra.ai ), an open-source JavaScript SDK for building agents on top of Vercel’s AI SDK. You can start a Mastra project with `npm create mastra` and create workflow graphs that can suspend/resume, build a RAG pipeline and write evals, give agents memory, create multi-agent workflows, and view it all in a local playground. Previously, we built Gatsby, the open-source React web framework. Later, we worked on an AI-powered CRM but it felt like we were having to roll all the AI bits (agentic workflows, evals, RAG) ourselves. We also noticed our friends building AI applications suffering from long iteration cycles: they were getting stuck debugging prompts, figuring out why their agents called (or didn’t call) tools, and writing lots of custom memory retrieval logic. At some point we just looked at each other and were like, why aren't we try...

Show HN: OpenAstra – Chat based open-source alternative to Postman Hi HN, I'm excited to finally launch this project. While existing tools like Postman excel at API discovery and testing, they often require us to navigate complex interfaces, manually construct requests, etc. That's why I created OpenAstra. The core idea is to combine the visual richness of traditional API tools with the simplicity of a chat interface. Think of it as "Postman meets ChatGPT" - allowing us to interact with APIs through natural conversation while retaining core essential features of traditional API tools. If you want to test an endpoint or understand what it does? Just ask. The project is still in its early stages, and there's much more to build. I'd love to hear what features you'd find most valuable, and of course, pull requests are always welcome! https://ift.tt/ZhG2qIY February 19, 2025 at 10:59PM

Show HN: Open-Sourcing My LLM Drag and Drop Website Builder Hey HN - OP here. I wrote some about this project in the following link, and there's a video demo as well: https://ift.tt/Sl5MEtb... This has been one of my favorite things I've ever worked on - the way the LLM collaborates with the user to accelerate tedious and hard work, the way you can directly edit the code instead of dealing with a panel of visual editing toggles - I think it has a lot of potential but I don't have time to pursue it anymore so open-sourcing it. The idea for this came out of conversations with a few people who were struggling with frontend development. For technical people, strictly using an LLM to write code can be tedious. To combat this, LLM usage is limited to getting started quickly, improving design, and wiring up frontend state. On the other hand, writing frontend code feels less efficient than just moving things around on a screen. Hence the drag and drop interface that makes it fast t...

One of my main goals was to do all of the pieces myself, and be able to understand every component of it, so I designed my own PCB, wrote the firmware, wrote a Game Boy and Game Boy Advance emulator for the FPGA (using the Chisel HDL), and designed a 3D-printed case. I detailed the design and development process in the linked post. It's quite long, but there are a lot of pictures and videos. Code and design files available on GitHub: https://ift.tt/cBT4ZWP , and an overview of the architecture: https://ift.tt/myJXETv... https://ift.tt/kenNGBq February 13, 2025 at 12:11AM

Show HN: Community Detection on Bluesky We ran the Leuven community detection algorithm on popular users on Bluesky (where the graph has edges determined by Jaccard similarity of a users' followers). We identified 118 communities and based on the names and descriptions of the top 10-20 users had LLMs generate title and descriptions for them. There are communities like "Feline enthusiasts", "Web Professionals", a bunch of NSFW ones and quite many communities are many different flavors of progressive/liberal activists. https://ift.tt/UF0woB5 February 12, 2025 at 03:39AM

Show HN: Colada for Claude I actually enjoy Claude.ai's interface and artifacts implementation. I didn't want to lift and shift over to another LLM tool. So, to get past the daily limits, I decided to build a simple Chrome extension which continues conversations using your own Anthropic API key (or using our managed key). In short: - Get past Claude.ai conversation limits - Bring your own Anthropic API key - Optionally use our managed unlimited API key - Preserve conversation context - Bring project knowledge context into your extended convos - Reference web search results anytime by asking "Search the web" Let me know what you think. Open to any and all feedback. https://usecolada.com February 12, 2025 at 12:08AM

Show HN: WhisperCat – An Audio Recorder and Transcription Tool Hi HN, I wanted to share my first open-source project with you all: WhisperCat . WhisperCat is a small desktop application for recording audio and transcribing it using OpenAI's Whisper API. I built this because I needed something simple and reliable for my own transcription workflows, and now I'm hoping it might be useful to others as well. It's still pretty early stage, but it works well for basic audio recording and transcription tasks. What It Does: Lets you record audio with your preferred microphone. Transcribes audio files automatically via Whisper (OpenAI's transcription API). Supports global hotkeys for recording (e.g., CTRL + R or a custom sequence like triple ALT). Runs in the background (system tray) when minimized. Has a basic microphone testing feature to help you pick the right device. Shows desktop notifications for events (e.g., when recording starts or errors happen). Platforms: WhisperCat ...

Making Enforcement Fair: Our New Plan for the State Daylighting Law By Rebecca Ashton-Dziedzan The new state "daylighting" law will help make intersections safer. We're announcing a new plan to implement California's "daylighting" traffic safety law in San Francisco. The state law bans parking within 20 feet of the approach side of a crosswalk. This rule helps improve visibility at intersections for both people walking and driving. The law applies to both marked and unmarked crosswalks. Our goal is to make this change fair and easy to follow. We also want to ensure San Francisco’s streets are safer for everyone. Our new plan is clear, fast and fair: No citations will be issued at...

Show HN: Neovim Plugin for iOS and macOS Development Over two years ago, I began exploring whether it was possible to shift my iOS development to Neovim. It took me over six months to resolve all issues and figure out how to connect everything, creating an environment with all the features required for development. After that, I decided to develop my own plugin to enable others to do the same. Since then, I have been developing apps for iOS and macOS using Neovim, for both my professional work and personal projects with no issues. This change has significantly boosted my productivity, and I no longer have to deal with Xcode's flaws. I can accomplish 95% of my work without needing to open Xcode. Before that, it seemed impossible to develop for Apple platforms outside of Xcode. I'm proud that I was stubborn enough to make it work after all those failures along the way. Neovim is an amazing project <3. https://github.com/wojciech-kulik/xcodebuild.nvim February 9, 2025 at 07:46P...

Show HN: A website that heatmaps your city based on your housing preferences For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a major park. Given that public transportation networks can sometimes make close things hard to get to and far things easy to get to, it's not always obvious whether a neighborhood actually even fits my criteria or not! The overarching goal of theretowhere.com is to allow you to make more informed moving decisions whi...

Show HN: A configuration management system for minimal *Nix environments I built this thing to scratch my itch for a simpler alternative to Ansible and similar for basic jobs like setting up a dev env, building containers, and provisioning small fleets of servers. Grateful for feedback on the approach!

Show HN: Upsonic: An AI agent framework with client-server architecture Three months ago, we started developing an open source agent framework. We previously tried existing frameworks in our enterprise product but faced challenges in certain areas. Problems we experienced: * We risked our stateless architecture when we wanted to add an agented feature to our existing system. Current frameworks lack server-client architecture, requiring significant effort to maintain statelessness when adding an agent framework to your application. * Scaling problem - needed to write Docker configurations as existing frameworks lack official Docker support. Each agent in my application required a separate container (e.g., Twitter page analysis, website scraping, automatic documentation writing, etc.), necessitating individual agent deployment and health checks monitoring. * Needed LLM calls for simple tasks - both fast and cost-effective solutions. With increased model capabilities, the framework should...

Show HN: Sveltos – Event-Driven Tool for Kubernetes Add-Ons and App Deployment Hi HN, Managing Kubernetes add-ons, policies, and configurations across multiple clusters can feel like herding cats. That’s where Sveltos comes in—a lightweight, open-source tool to make managing fleets of Kubernetes clusters simple, scalable, and secure. What Can Sveltos Do? 1. Centralized Management – Deploy apps, add-ons, and policies from a single control plane, instead of setting up GitOps tooling on every cluster. A lightweight agent on each managed cluster keeps things efficient. 2. Security: Best of Push & Pull GitOps – Unlike traditional GitOps, which either requires exposing your clusters to external Git credentials (push) or setting up agents on each cluster (pull), Sveltos combines centralized GitOps management with secure pull-based configurations and push-based deployments—keeping credentials in a single, secure location. 3. Dynamic & Event-Driven Cluster Management – Just apply labels...

Show HN: I made a tool to help you save and execute commands in a directory Hi HN! A lot of times I end up with sets of commands I want to run in a project directory: building packages, running ansible to deploy things, cleaning up files, etc. Makefiles always felt rather overkill for this and I like having just a YAML file with the name, description, and commands that are available and for a menu to display with that information. This is that program. I had originally written it many years ago in Perl. I have been learning Go and this seemed like a great project to port. I hope you find it useful, thanks for reading! https://ift.tt/YIJWjOq February 5, 2025 at 11:05PM

Show HN: Haystack Code Reviewer – Perform code reviews on a canvas Hi HN! We’re building Haystack Code Reviewer, a tool that lays out code diffs for a GitHub pull request on an interactive canvas. Instead of scrolling through diffs line-by-line, you can view all changes in a more connected, visual format – similar to viewing a call graph. We hope this will make it easier and less cognitively taxing to understand how different changes across files work together. For a quick overview, check out our short demo video: https://www.youtube.com/watch?v=QeOz70x0WPE . If you would like to give it a spin, head over to https://ift.tt/2oryLDP , click the “Review pull request button” in the top toolbar, and load any pull request via URL or pick a pull request from a dropdown. We built Haystack Code Reviewer because we found pull requests difficult to review in a pure textual format — especially when hopping between multiple files or trying to break down complex changes. Oftentimes, pull request aut...

Show HN: Mandarin Word Segmenter with Translation I've built mandoBot, a web app that segments and translates Mandarin Chinese text. This is a Django API (using Django-Ninja and PostgreSQL) and a NextJS front-end (with Typescript and Chakra). For a sample of what this app does, head to https://ift.tt/3eFQ9g5 . This is my presentation of the first chapter of a classic story from the Republican era of Chinese fiction, Diary of a Madman by Lu Xun. Other chapters are located in the "Reading Room" section of the app. This app exists because reading Mandarin is very hard for learners (like me), since Mandarin text does not separate words using spaces in the same way Western languages do. But extensive reading is the most effective way to learn vocabulary and grammar. Thus, learning Mandarin by reading requires first memorizing hundreds or thousands of words, before you can even know where one word ends and the next word begins. I'm solving this problem by allowing users to ...

Show HN: Open-source schema based Change-Data-Capture utility for Postgres I am currently working on a Node.js utility for a schema-based approach on CDC for Postgres. It is a lightweight utility that you can plug on top of your existing WAL events service (eg. Debezium, WAL-listener...) and allows you to define schemas to listen to. Instead of listening to raw individual table-level events, you can aggregate those events into high-level schema events automatically. Conceptually, it is like having WAL events but on an SQL view, any modification to a table the view is based on would trigger a high-level event on the view itself. This has many real-world applications including: - Syncing your single source of truth (Postrges) to another store (eg. Elastic / Algolia...) - Have a reliable event-driven architecture where you can change the underlying data model while keeping the contract identical I was highly inspired by pgsync but wanted to build a lightweight, generic version of the idea...
