Show HN: Pocket2Linkding – Migrate from Mozilla Pocket to Linkding With the Mozilla Pocket shutdown coming up in about two weeks, I thought I'd share this quick tool to migrate to linkding in case it's helpful to others. After reviewing self-hosted options to Pocket, I decided linkding has the best combination of features. (The creator/author of linkding has done a great job -- however, I plan to eventually create a new tool that is based on linkding but adds some new features that the author has indicated he doesn't want to include [I’m currently using a fork, but I want to expand on it further].)

Show HN: Magnitude – open-source AI browser automation framework Hey HN, Anders and Tom here. We had a post about our AI test automation framework 2 months ago that got a decent amount of traction ( https://ift.tt/hwvmTMD ). We got some great feedback from the community, with the most positive response being about our vision-first approach used in our browser agent. However, many wanted to use the underlying agent outside the testing domain. So today, we're releasing our fully featured AI browser automation framework. You can use it to automate tasks on the web, integrate between apps without APIs, extract data, test your web apps, or as a building block for your own browser agents. Traditionally, browser automation could only be done via the DOM, even though that’s not how humans use browsers. Most browser agents are still stuck in this paradigm. With a vision-first approach, we avoid relying on flaky DOM navigation and perform better on complex interactions found in a broad varie...

Show HN: TNX API – Natural Language Interactions with Your Database Hey HN! I built TNX API to make working with databases as simple as asking a question in plain English. What it does: - You write a natural language prompt (e.g., "List products with price > 20 USD") - Our system turns it into SQL and runs it - You get actual results, optionally visualized - Your data stays private – nothing is stored, the AI doesn‘t see it, and the API forgets immediately after replying Why I made this: Writing SQL for routine questions is https://ift.tt/CDGao4q still a blocker for many teams. I wanted a privacy-first, plug-and-play API that just works with natural language. TNX doesn’t just translate — it executes the queries and returns actual answers (not just SQL). Examples: - You ask: “Total sales by product category this year?” → TNX replies: [furniture: $43,000, electronics: $12,000] + “Want a chart for this?” - You ask: “Which customers didn’t order in the last 90 days?” → TNX rep...

Show HN: Pickaxe – a TypeScript library for building AI agents Hey HN, Gabe and Alexander here from Hatchet. Today we're releasing Pickaxe, a Typescript library to build AI agents which are scalable and fault-tolerant. Here's a demo: https://ift.tt/crVnydW... Pickaxe provides a simple set of primitives for building agents which can automatically checkpoint their state and suspend or resume processing (also known as durable execution) while waiting for external events (like a human in the loop). The library is based on common patterns we've seen when helping Hatchet users run millions of agent executions per day. Unlike other tools, Pickaxe is not a framework. It does not have any opinions or abstractions for implementing agent memory, prompting, context, or calling LLMs directly. Its only focus is making AI agents more observable and reliable. As agents start to scale, there are generally three big problems that emerge: 1. Agents are long-running compared to other parts of ...

Show HN: Report idling vehicles in NYC (and get a cut of the fines) with AI New York City has this cool program that lets anyone report idling commercial vehicles and get a large cut of the fines [1]. It's been in the news recently [2]. I've filed a few reports, and I found the process frustrating and error-prone. The forms are fiddly, there's way too much information that needs to be copied down from the video by hand, you have to use a third-party app to take a timestamped video and a different app to compress it before uploading, and approximately none of it can be done on your phone — the device you probably used to record your video in the first place. I built Idle Reporter to make filing complaints into a five-minute process that you can do entirely from your phone. Idle Reporter uses AI to automatically extract all the required information and screenshots from the video and fill out the form for you. It compresses your video, adds the required screenshots, and upload...

Show HN: Kichan.ai, Chrome extension generates JavaScript to augment any website Hey HN! I've been working on https://kichan.ai , a Chrome extension that lets you modify any website using prompts. It uses Google Gemini to generate JavaScript that runs directly on your browser web page. How it works: Click the extension to open a side panel. Type what you want to do like "Remove all ads", "Add a share button", or "Make this table sortable". KICHAN generates JavaScript using Gemini 2.5 Flash and executes it immediately. Your custom scripts are saved and can run automatically on specific websites. Key features include context-aware generation where you can right-click any element to add it to a "context buffer" that helps the AI understand exactly what you want to modify. Scripts can also run automatically on matching URLs using glob patterns. Example use cases I've found useful include automating repetitive tasks like auto-reloading my GitH...

Show HN: Delve, an open source (AGPL) enterprise-grade data analytics platform Hello, I am excited to announce the release of my project that I've been working on for quite a while. It has gone through many iterations. I believe that I now have a scalable platform that can efficiently ingest, search and report on large quantities of data. If you are at a very large scale, there will need to be some work to streamline your database access, but it is very possible to build a flexible and robust solution. Delve is built using Django, Django Rest Framework, webpack, JS and SCSS. Delve can be extended with apps, which are actually specially built Django apps. Delve has a unix-pipe-like search language that is powered by simple python scripts. The Delve Web UI has support for showing data in tables, line charts and bar charts with more visualizations on the way. I am excited to hear your feedback and suggestions. I will be trying to monitor the comments and reply quickly. https://ift.tt/...

Show HN: Workout.cool – Open-source fitness coaching platform I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say.

Show HN: I built a FOSS tool to run your Steam games in the Cloud I wanted to play my Steam games but my aging PC couldn’t keep up, so I built Cloudy Pad - a tool to run Steam in the Cloud (GitHub: https://ift.tt/1TF0q3J ) It runs on AWS, Azure, GCP, Scaleway and Paperspace with various cost optimizations and safeties: - Cost alerts - Auto stop inactive instances to avoid unwanted cost - Disk snapshots and data cleanup for cost efficiency - Spot instance support Under the hood: a Linux VM and a container running Sunshine (a streaming server https://ift.tt/BEFQTwq ) with Steam. Most Windows games work just fine thanks to Proton. It streams effortlessly at 1080p 100+ FPS - I recently played Baldur’s Gate III and Clair Obscur in Ultra, ran like a breeze.

Show HN: TagLib-Wasm, a TypeScript-first music tagging library I was RIF'd last week so I finally had the chance to try some non-AIDE solutions (e.g. OpenAI Codex, Google Janus, Claude Code) for the purpose of building something non-trivial. I decided to create a CLI utility related to the care and feeding of my music library. Almost instantly, I ran into a problem: There are no complete music metadata libraries for TypeScript/JavaScript runtimes. TagLib ( https://taglib.org/ ) looked great, but I couldn't find any good TypeScript wrappers for it, and I wanted to avoid including OS-specific binaries in a library that might be distributed as part of standalone tools.

Show HN: Canine – A Heroku alternative built on Kubernetes Hello HN! I've been working on Canine for about a year now. It started when I was sick of paying the overhead of using stuff like Heroku, Render, Fly, etc to host some web apps that I've built. At one point I was paying over $400 a month for hosting these in the cloud. Last year I moved all my stuff to Hetzner. For a 4GB machine, the cost of various providers: Heroku = $260 Fly.io = $65 Render = $85 Hetzner = $4 (This problem gets a lot worse when you need > 4GB) The only downside of using Hetzner is that there isn’t a super straightforward way to do stuff like: - DNS management / SSL certificate management - Team management - Github integration But I figured it should be easy to quickly build something like Heroku for my Hetzner instance. Turns out it was a bit harder than expected, but after a year, I’ve made some good progress The best part of Canine, is that it also makes it trivial to host any helm chart, which ...

Show HN: Dory – A Simple Static Site Generator for MDX Docs I'm Hemang, co-founder of Clidey. While building Docucod – our platform for generating and maintaining technical documentation – we needed a simple, fast, and flexible way to host the docs. We started with Next.js + Vercel, but it felt like overkill. SSR wasn’t needed, and we ran into vague webhook errors and deployment issues. It felt like too much complexity for a static documentation site. So we built Dory – a minimal static site generator optimized for technical documentation. It's built with Preact, Vite, Tailwind, FontAwesome, Mermaid, and Typescript. What makes Dory work for us: • Reads a folder of .mdx files • A single dory.json defines structure/layout • No SSR, no cloud lock-in • Fast builds, minimal config, deploy anywhere The goal with Dory is to keep things truly simple — easy to set up, easy to use, and effortless to deploy for anyone building static documentation.

Show HN: Trieve CLI – Terminal-Based LLM Agent Loop with Search Tool for PDFs Hi HN, I built a CLI for uploading documents and querying them with an LLM agent that uses search tools rather than stuffing everything into the context window. I recorded a demo using the CrossFit 2025 rulebook that shows how this approach compares to traditional RAG and direct context injection[1]. The core insight is that LLMs running in loops with tool access are unreasonably effective at this kind of knowledge retrieval task[2]. Instead of hoping the right chunks make it into your context, the agent can iteratively search, refine queries, and reason about what it finds. The CLI handles the full workflow: ```bash trieve upload ./document.pdf trieve ask "What are the key findings?" ``` You can customize the RAG behavior, check upload status, and the responses stream back with expandable source references. I really enjoy having this workflow available in the terminal and I'm curious if others ...

This app is my personal fix for two long-standing frustrations with the macOS interface. First, I wanted to restore Dock-click minimize. On other operating systems, I was used to clicking an app's icon to minimize its window—a simple, fast toggle. On a Mac, that second click does nothing, which always felt like a dead end in my workflow. Second, I was tired of having to deal with the tiny buttons.

Show HN: Tool-Assisted Speedrunning the Boring Parts of Animal Crossing (GCN) I recently dug my Nintendo GameCube out of storage to revisit the first Animal Crossing game. Things were mostly as I remembered, but the game's heavy reliance on a clunky on-screen keyboard quickly wore my patience thin. Unwilling to accept this subpar experience, I did what any rational person would do and ordered a rare, Japan-exclusive, keyboard/controller hybrid on eBay, then used a Raspberry Pi Pico to 1. listen for keypresses and 2. send simulated controller events to the GameCube, automating typing in Animal Crossing at a Tool-Assisted Speedrun level. Of course, this oddball controller's keycaps didn't map perfectly to Animal Crossing's in-game character set, so I watched a 10 hour FreeCAD tutorial at 2x speed, then modeled the 7 keycap profiles to create 81 custom, 3D printed keycaps, taking care to include even the most esoteric Greek and Old English characters that Nintendo chose to...

Show HN: UserWatch – AI product analyst. Instant dashbords, AB tests, AI replays tldr: it's essentially Cursor but for Product Analytics. AI that sets up your PostHog. Hey, I'm Dima, a former PM who led product redesign and had a constant analytics hangover, and now a solo SF founder who only has time either to ship a new product or recruit users. Analytics is always lagging behind and piling up into an annoying debt. I was also reflecting on product management as a job in general and was thinking about hard skills, and came to a conclusion that analytics is the only hard skill of a PM, and analytics is essentially the coding of the PM. Given the AI and MCP boom, I figured it's possible to automate even that. So I built UserWatch: an AI product analyst that connects to PostHog and sets everything up for you. (long warm up before pitch ik, sry) You just tell it what you want in plain language, “show me the onboarding funnel” or “run an A/B test on the pricing page” and it do...

Show HN: I built a tool to use my homelab apps remotely without a full VPN Hi HN, I'd like to share a small Go utility I wrote called prxy. The idea was born out of my frustration with accessing my self-hosted services when I'm on the go. I use WireGuard to connect to my homelab, but I really dislike sending all my computer's traffic through my home network — it slows things down and is inconvenient. I wanted proper application-level split-tunneling. A tool I love, wireproxy, got me most of the way there by creating an HTTP proxy from a WireGuard peer. This is perfect for apps that let you configure a proxy. The problem was the other 10%: apps that don't. Think of browser extensions or simple clients that just have a single URL field. That's why I created prxy. It's a dead-simple local reverse proxy that forwards traffic to another outbound proxy (like wireproxy). The key feature is that it automatically rewrites the Host header, so the request reaches the corre...

Show HN: A "Course" as an MCP Server We wanted to build a course for new Mastra devs to get started quickly. However, we knew videos would go out of date and be more difficult to maintain. We decided to launch our "course" as an MCP server. This way your coding agent actually teaches the course content to you and can help you write the code. We think this is a really interactive way to learn. Using an editor with MCP support (such as Cursor, Windsurf, or VSCode), your code agent will call the appropriate MCP tools which will return context for the agent. This context tries to instruct the agent that it should be teaching you the content, not just doing the work for you. The course is still pretty experimental and some models work better than others. Code is available in the Mastra Github repo in the mcp-docs-server package ( https://ift.tt/gnml03v... ) https://ift.tt/7MYkOJZ June 11, 2025 at 03:36AM

Show HN: Munal OS: a graphical experimental OS with WASM sandboxing Hello HN! Showing off the first version of Munal OS, an experimental operating system I have been writing in Rust on and off for the past few years. https://ift.tt/AzRGj65 It's an unikernel design that is compiled as a single EFI binary and does not use virtual address spaces for process isolation. Instead, applications are compiled to WASM and run inside of an embedded WASM engine. Other features: * Fully graphical interface in HD resolution with mouse and keyboard support * Desktop shell with window manager and contextual radial menus * PCI and VirtIO drivers * Ethernet and TCP stack * Customizable UI toolkit providing various widgets, responsive layouts and flexible text rendering * Embedded selection of applications including: * A web browser supporting DNS, HTTPS and very basic HTML * A text editor * A Python terminal Checkout the README for the technical breakdown.

Show HN: AI that extracts brand identity from websites to generate ads I built this because I kept procrastinating on creating ads for my projects. The technical challenge was interesting: how do you teach AI to extract "brand identity" from a website? Turns out websites are messy. Finding the actual logo vs random images, identifying brand colors vs generic link colors, understanding brand voice from homepage copy. The solution: Custom vision models + CSS parsing + GPT-4 for voice analysis. You paste a URL, it extracts brand elements, generates platform-specific ads. Not trying to "disrupt advertising" or anything dramatic. Just solving the specific problem of "I need a Facebook ad but Canva makes me want to cry." Built with Next.js, custom image processing pipeline, OpenAI API. The brand extraction accuracy is around 85% for well-structured sites, lower for sites that are... creative with their CSS. Happy to discuss the technical approach or share code s...

Show HN: AI game animation sprite generator I tried to build AI game animation generator last year ( https://ift.tt/Em63jbq ), a lot of people were interested, but it failed, mainly because the technology was not good enough. 1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation. You can generate all kinds of game character animation sprites with only 1 image. 1, upload your image of your character 2, choose the action you want 3, generate! Support basic actions like Run, Jump, Punch and complicated ones like: Shoryuken, Spinning kick, etc. High quality sprite sheet will be directly generated to use in Unity and any game engine. If you are an indie game developer, you don't need to high an artist or animator to develop you game. For studios, it's 10x cost saving and 10x efficiency as no more creating animations for 100 NPCs 100 times. Please check it out, looking forward to yo...

Show HN: Lightweight Durable Workflows Built on Postgres Hi HN! This is Qian here with Peter (KraftyOne) and Jeremy (jedberg). We’re building DBOS, an open-source, lightweight durable workflows library that you can add to Python apps in just a few lines of code. It’s comparable to popular open-source workflow and queue libraries like Airflow and Celery, but more lightweight with a greater focus on reliability and automatically recovering from failures. Our goal in building DBOS is to make workflows lightweight and flexible so you can add them to your existing apps with minimal work. Everything you need to run durable workflows and queues is contained in this Python library. You don’t need to manage a separate workflow server: just install the library, connect it to a Postgres database (to store workflow/queue state) and you’re good to go. DBOS workflows make your program durable by checkpointing its state in Postgres. If your program ever fails, when it restarts all your workflows will...

Show HN: Run 30B model in 4GB Active Memory We have built fused operator kernels for structured contextual sparsity to avoid loading and computing activations with feed forward layer weights that eventually zero out by the activation. The result? We are seeing 5X faster MLP layer performance in transformers with 50% lesser memory consumption avoiding the sleeping nodes in every token prediction. For Llama 3.2, Feed forward layers accounted for 30% of total weights and forward pass computation resulting in 1.6-1.8x increase in throughput: Sparse LLaMA 3.2 3B vs LLaMA 3.2 3B (on HuggingFace Implementation): - Time to First Token (TTFT): 1.51× faster (1.209s → 0.803s) - Output Generation Speed: 1.79× faster (0.7 → 1.2 tokens/sec) - Total Throughput: 1.78× faster (0.7 → 1.3 tokens/sec) - Memory Usage: 26.4% reduction (6.125GB → 4.15GB) Find the operator kernels with differential weight caching open sourced at github/sparse_transformers.

Show HN: OSS's Answer to Cursor's Codebase Level Context for Large Projects Hey HN, We've all seen tools like Cursor pull in context from an entire codebase to help LLMs understand large projects. I wanted an open-source way to get that same deep, structural understanding. That's why I built Code-to-Knowledge-Graph. It uses VS Code's Language Server Protocol (LSP) to parse your whole project and builds a detailed knowledge graph – capturing all your functions, classes, variables, and how they call, inherit, or reference each other. This graph is the "codebase-level context" to improve coding agents at scale. The idea was inspired by research showing that knowledge graphs significantly improve retrieval-augmented generation and structural reasoning (such as "Knowledge Graph-Augmented Language Models" (Zhang et al., 2022 and "GraphCodeBERT") Would love to hear your thoughts, feedback, or ideas for improvement! https://ift.tt/JwHlvRs June ...

Show HN: Bonvago.com – Shows hidden hotel discounts and bonus rewards I built https://www.Bonvago.com in my spare time as a friendlier alternative to other hotel booking engines. Slow dev server, no VC cash, no hype—just me + caffeine, so thanks for your patience. Every “painfully’ slow search helps improve speed. What it does: - Unlocks hidden rates (AAA, Costco, double points, etc.) - Summarizes hotel reviews using AI so you don’t have to doomscroll. - Gives you BONV points (aka tokens you can spend on hotel bookings). - Travel agents get 10% commissions (most OTAs give you like... 6%) Up Next (maybe): Flights, rental cars, tours, cruises—and an AI agent to help you plan and book entire trips. Heads up: It’s live. If you’re just testing it out, pick refundable rates or risk paying real money. You’ve been warned. Would love any feedback—design, bugs, broken links, wish list features, whatever. Appreciate you. Much love to HN! June 4, 2025 at 10:25PM
