Show HN: Simple Certificate Decoder Tool Sometimes I need to quickly check certificates, especially key details like SANs, expiration dates, issuer info, etc. I know there are dozens (if not hundreds) of certificate decoders out there already, but I built my own—mostly for fun, but also because I prefer tools that are clean, simple, and straightforward to use. Would appreciate your feedback! https://ift.tt/GQMZU01 March 9, 2025 at 12:39AM

Show HN: Rio – Open Source Web Apps in Pure Python, No JS/HTML/CSS Needed Hey HN, Over the past 10 months, my friends and I created an open source project called Rio to help Python developers build modern web apps without needing HTML, CSS, or JavaScript. Whether you're working on a simple internal tool or a complex multi-page app, Rio lets you stay in the Python ecosystem without needing to learn frontend frameworks. With Rio, the UI is defined using Python components, inspired by React and Flutter. Instead of writing HTML/CSS, you compose reusable UI elements in Python and let Rio handle rendering and state updates. The backend and frontend stay seamlessly connected using WebSockets, so data syncs automatically without manual API calls. Since Rio is fully Python-native, you can integrate it with any Python library, from data science tools to AI models. Many Python projects rely on popular libraries like React internally, but the core benefits and elegance of these libraries are o...

Show HN: A big tech dev experience for an open source CMS # Show HN: A big tech dev experience for an open source CMS. Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline. We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two. The tooling we're showing today is extremely simplistic (and the AI is frankly bad) but this is intentional. We're more focused on showing the dev experience and community aspects. We'd like to make it easier to contribute to this project than edit Wikipedia. Communi...

Show HN: AI Video Prompt Generator-Transform idea into professional video prompt I'm excited to share AI Video Prompt Generator, a tool born from few hours of experimenting with AI video generation models. We've found that the key to getting great AI-generated videos isn't just about having a good idea - it's about knowing how to communicate that idea to the AI in a way it understands. Key features: • 12 specialized video categories (from cinematic scenes to product showcases) • 13 style parameter categories covering everything from lighting to camera angles • Pre-built templates you can customize for your needs • Simple interface for both beginners and professionals • Direct scene description option for quick results What makes it special: Structured approach: Instead of guessing what works, use proven prompt structures that get consistent results Style control: Fine-tune every aspect of your video's look with specific style modifiers Flexible workflows: Whether yo...

Show HN: Fast-agent – Compose MCP enabled Agents and Workflows in minutes Hello, HN. I've created fast-agent to make building my own products easier - and remove the friction between defining Prompts, MCP Servers and their composition. It uses a simple, declarative style that's easy to work with and source control - with inbuilt support for the patterns in the Building Effective Agents paper. Because you can "warm-up" and interact with Agents before, during or after the workflows, it's easy to diagnose and tune Agent prompts and behaviour for later runs. Being able to set these workflows up makes LLM Context Management and Tool Selection a lot easier and can vastly improve output quality for little effort. For MCP Server developers you can see how different models interpret tool descriptions. There's also MCP Roots support, and it comes bundled with a ChatGPT style data-analysis tool (`fast-agent bootstrap data-analysis`) as one of the demonstrations. One of t...

Show HN: iMCP – Connect Your macOS Messages, Calendar, and More to Claude Interact with all your Apple apps and data via Claude Desktop – or your favorite MCP client. MCPs are super hot right now but they're definitely still developer-grade user experiences. We built iMCP because we wanted to see what it would take to start to build a more consumer friendly experience on top of MCP. Not just connecting IDEs to databases and SaaS APIs. iMCP is open source and built entirely in Swift with our MCP Swift implementation: https://ift.tt/vD0BQzO Tell us what you think! https://ift.tt/Za1GCQu March 6, 2025 at 10:57PM

Show HN: PG-Capture – a better way to sync Postgres with Algolia (or Elastic) Hello HN! Keeping Elasticsearch or Algolia in sync with Postgres is a pain when your data spans multiple tables. Traditional CDC tools like Debezium capture table-level events but don’t help when you need to index a full entity composed of related records. That's why I built PG-Capture. PG-Capture lets you define a schema as complex as you need, aggregate table-level events, and reconstruct structured objects spanning multiple tables. It then publishes them as meaningful domain-level events to any queue (RabbitMQ, SQS, etc.). PG-Capture does NOT replace Debezium, it works on top of it (or any other event source). This keeps it flexible and tool-agnostic. I'd love to hear your thoughts! Does this solve a problem you've run into? Would you use something like this in your stack? Feedback is welcome! https://ift.tt/1L5Y3Pe March 1, 2025 at 04:18PM

Show HN: Sonauto API – Generative music for developers Hello again HN, Since our launch ten months ago, my cofounder and I have continued to improve our music model significantly. You can listen to some cool Staff Picks songs from the latest version here https://sonauto.ai/ , listen to an acapella song I made for my housemate here https://ift.tt/CnRUVlP , or try the free and unlimited generations yourself. However, given there are only two of us right now competing in the "best model and average user UI" race we haven't had the time to build some of the really neat ideas our users and pro musicians have been dreaming up (e..g, DAW plugins, live performance transition generators, etc). The hacker musician community has a rich history of taking new tech and doing really cool and unexpected stuff with it, too. As such, we're opening up an API that gives full access to the features of our underlying diffusion model (e.g., generation, inpainting, extensions, transition gen...

Show HN: Open-Source Windows AI assistant that uses Word, Excel through COM This started off as a project to understand how to get LLMs to interface with more traditional desktop softwares.

Show HN: Mmar – open-source, zero-dependancy, cross-platform HTTP tunneling Hey HN! For the past couple of months, I've been working on and off on a cool project I'm excited to share. mmar (pronounced "ma-mar") is an open-source, zero dependency, cross platform and self-hostable HTTP tunnel built in Go. It allows you to easily expose your localhost to the world on a public URL. You can easily create an HTTP tunnel right away for free on a randomly generated subdomain on "*.mmar.dev" if you don't feel like self-hosting. This isn't something new, in fact there's quite a few of alternative HTTP tunneling tools out there. mmar is my attempt to optimize for a super easy developer experience and simplified implementation. None the less, I had a blast building it and I think developers could find it pretty useful. Additionally, I documented the whole process of building mmar through devlogs. You can read about the thought process and implementation deta...

Show HN: Fast Transition from Firefox to Librewolf After looking at various browser alternatives to Firefox (my daily driver for years), I decided to try LibreWolf and the transition was trivial on a Debian based system (by HN standards). My extensions even ran without logging in (YMMV). First install LibreWolf: sudo apt update && sudo apt install extrepo -y sudo extrepo enable librewolf sudo apt update && sudo apt install librewolf -y Second: After closing Firefox, copy Firefox profile (in ~/.mozilla/firefox/) to Librevox profile (in ~/.librewolf/). Note: I copied the profile into the default profile (as seen in about:profiles) not default-default. I then launched the profile and all my tabs were restored, bookmarks, logins, etc. I will update if something seems broken. March 3, 2025 at 01:14AM

Show HN: I built an app to convert ChatGPT Deep Research to PDFs with footnotes Whilst ChatGPT Deep Research is very useful for generating in-depth reports, it's time consuming to copy, reformat the text (thousands of words) and clean referenced hyperlinks for use in a professional context. Out of frustration, I built deep research docs to help save time by automating the reformatting, cleaning links, footnote references, and conversion to shareable PDF format. Hopefully this helps you save time to focus on meaningful work. Let me know your feedback. https://ift.tt/14Tt6ju March 1, 2025 at 07:52PM
