Show HN: Subtrace – Wireshark for Docker Containers https://bit.ly/4124xGF

Show HN: Subtrace – Wireshark for Docker Containers Hey HN, we built Subtrace ( https://bit.ly/431BXI9 ) to let you see all incoming and outgoing requests in your backend server—like Wireshark, but for Docker containers. It comes with a Chrome DevTools-like interface. Check out this video: https://www.youtube.com/watch?v=OsGa6ZwVxdA , and see our docs for examples: https://bit.ly/4hGMqx3 . Subtrace lets you see every request with full payload, headers, status code, and latency details. Tools like Sentry and OpenTelemetry often leave out these crucial details, making prod debugging slow and annoying. Most of the time, all I want to see are the headers and JSON payload of real backend requests, but it's impossible to do that in today's tools without excessive logging, which just makes everything slower and more annoying. Subtrace shows you every backend request flowing through your system. You can use simple filters to search for the requests you care about and inspect their details. Internally, Subtrace intercepts all network-related Linux syscalls using Seccomp BPF so that it can act as a proxy for all incoming and outgoing TCP connections. It then parses HTTP requests out of the proxied TCP stream and sends them to the browser over WebSocket. The Chrome DevTools Network tab is already ubiquitous for viewing HTTP requests in the frontend, so we repurposed it to work in the browser like any other app (we were surprised that it's just a bunch of TypeScript). Setup is just one command for any Linux program written in any language. You can use Subtrace by adding a `subtrace run` prefix to your backend server startup command. No signup required.

Show HN: TimeRetain – A browser-based personal time tracker, no sign-up needed https://bit.ly/4jZRqP1

Show HN: TimeRetain – A browser-based personal time tracker, no sign-up needed Hi HN, I built TimeRetain: a time tracker for individuals that runs 100% in your browser. No sign up, no personal data stored, and free while I’m working on the beta. Click the white demo banner to check it out quickly :) I’m using it to track my hours at work (e.g., overtime, and what I’ve done so I come prepared for stand up). In 2023 I launched it here [1], but with a back-end. After I became interested in local-first, I realized JS could handle everything Postgres did - so I ported it. Time data now never leaves your browser and the app will ping you to run an export from time to time. I also followed up on some of the feedback in the previous thread (it now has a pause button, a dedicated data export page, no longer relies on a working back-end, and I fixed the spacing in the name). It’s not a true local first app just yet (e.g., it's not a PWA, and backing up using the File System API is on my list), but I plan on making it one should it gain some traction. One of the other things I might add is encrypted at rest storage and sync of events, for which the foundation is done (it’s event-based and events are ordered using a HLC timestamp in IndexedDB). I wonder, though: is multi-device sync even necessary? I would much rather prefer not to store any personal data at all, even if it’s encrypted. Do you need sync? And if so, what would be your ideal solution? Would love to hear your thoughts in general. Thank you! [1] https://bit.ly/3CYaIR1 https://bit.ly/3J4Asiy February 17, 2025 at 11:57AM

Show HN: Generic and variadic printing library in C https://bit.ly/3QomieE

Show HN: Generic and variadic printing library in C I was making a printf wrapper with some extra features when I thought "hey, now that C has _Generic, is there any way to combine that with varargs?". The closest solution I found online was this: https://bit.ly/3dFmlAl Which works, but only under GCC (since it uses an extension instead of _Generic) and its not very robust in general. So, I rolled my own, with a different macro hack and I think it came out reasonably well. Its not documented yet, because I'm unsure about the interface, but extending it with user structs is also possible without editing the header. (Example in 'example-user-type.c'.) https://bit.ly/40Xohv8 February 17, 2025 at 10:54PM

Show HN: Klipy – AI GIFs, Clips, GIFs, Memes and Stickers API with Monetization https://bit.ly/4gKh87s

Show HN: Klipy – AI GIFs, Clips, GIFs, Memes and Stickers API with Monetization Hey HN, Over the past two years, my co-founder and I have been building https://bit.ly/42YDcHY — an API of 10m+ GIFs, AI GIFs, Clips, Stickers, and Memes, focused on efficiency and monetization. Unlike GIPHY/Tenor, our goal was to create a cost-efficient infrastructure that allows platforms to integrate GIFs seamlessly while generating revenue for content creators and platforms - and keeping the API free forever, unlike GIPHY. The process is straightforward: * Platforms integrate our API and enable our Revenue API (optional) * Ads are placed between content, ensuring high CTRs while maintaining a UX-friendly experience * This unlocks new exclusive ad inventory for the market, allowing apps to generate more revenue than traditional ad placements Currently, our infrastructure handles 4 billion requests per month (content API requests + revenue API requests to and from ad networks) while keeping server costs under $1500. We've already integrated with several platforms, including Ridmik, Fleksy, iMe Messenger, and others. Additionally, we’re live on Slack, Canva, Figma, Integrately, and RapidAPI, with bigger names coming soon. I'd be happy to provide a lifetime free API key to anyone interested in integrating our features, with or without the revenue API. * API Docs: https://bit.ly/42Ygm3i * Demo Video: https://youtu.be/HOwNz_kXBSc P.S. Our goal after next funding round is to develop an AI model that generates short and long-form media content for various purposes. If you’re interested in collaborating, let’s chat! Would love to hear your thoughts and feedback! https://bit.ly/42YDcHY February 18, 2025 at 12:47AM

Show HN: I listed all component libraries for any frameworks https://bit.ly/4kdjxKO

Show HN: I listed all component libraries for any frameworks I quit my dev job 2 years ago to work on projects I actually care about. I built a CRM for philanthropy as a nonprofit, and on the side, I tinker with fun projects to learn new languages and sharpen my skills. Recently, I was looking for new component libraries to use, but I realized… there’s no single platform showcasing ALL component libraries across frameworks—especially independent, bootstrapped ones. No wonder so many projects default to MUI, DaisyUI, and other mainstream options. So, I decided to fix that. I collected 75+ libraries for React, Vue, Angular, Svelte, Rails, Nuxt, and more, then categorized them by features like Dark Mode support, Accessibility, and Customizability. If you've built a component library, you can submit it for free. After launch, users requested more frameworks—so I automated the process with Make, letting me add new libraries in under an hour. Hope you'll find new libraries to try on for your next projects and let me know if you know more or want to see new frameworks added to it https://bit.ly/4k53IWy February 17, 2025 at 08:08AM

Show HN: Letting LLMs Run a Debugger https://bit.ly/4b2Bpnp

Show HN: Letting LLMs Run a Debugger Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). * Automated Breakpoints: It automatically sets and manages breakpoints based on both code analysis and LLM suggestions. * LLM Guidance: With live debugging context, the LLM can suggest actions like stepping through code or adjusting breakpoints in real time. I built this out of curiosity to see if combining static code with runtime data could help LLMs solve bugs more effectively. It’s rough around the edges and definitely not production-ready I’m not planning on maintaining it further. But I thought it was a fun experiment and wanted to share it with you all. Check out the attached video demo to see it in action. Would love to hear your thoughts and any feedback you might have! Cheers. https://bit.ly/3EAtLVg February 12, 2025 at 10:54AM

Show HN: Lightweight and robust CLI color converting utility https://bit.ly/4hF9Xi0

Show HN: Lightweight and robust CLI color converting utility I started this project because I found myself converting between Hex and RGB a lot. As I was frequently visiting various color picker websites, I began thinking more and more about how color conversions even work in the first place. What is a color space? Using any random color-picker online to go from RBG<->Hex works plenty fine, but, I think CLI tools are cool. I'm still pretty new to the Linux scene, and I really enjoy finding random command line programs to play with. I searched around a bit on Github and the AUR and couldn't find any CLI color conversion utilities, which I honestly found surprising (maybe I didn't look hard enough). I decided I'd really enjoy trying to make a simple command line program for RGB<->Hex, and the scope slowly expanded. I could see myself expanding it (maybe including more color formats, suggesting complementary colors) but for now, unless people discover ways to break it or offer any pull requests, I think I'll be moving on to other projects. It has no dependencies besides Python, and can be easily installed on mac/linux (see the README for more). I'm not certain how you'd set it up as a command line program on Windows, but you can just use Python in cmd to use the script anyway! https://bit.ly/4gKzwgr February 15, 2025 at 12:31AM
