Changeloghub – Automatically create beautiful changelogpages (beta)
Hey HN, I built ChangelogHub (https://changeloghub.com) to automate something that is always last on my list for every release: writing clean and human-readable changelogs. Human-readable being the key phrase here. Writing changelogs manually is tedious, especially for backend/infrastructure changes that users never see but matter a lot. I wanted something that didn’t just rephrase commit messages, but actually understood the code diffs. HOW IT WORKS: - Analyzes diffs from PRs or direct commits - Summarizes the changes using OpenAI (code-diffs+custom prompt + heuristics) -…
What it does
In the maker’s words, at launch
Hey HN, I built ChangelogHub (https://changeloghub.com) to automate something that is always last on my list for every release: writing clean and human-readable changelogs. Human-readable being the key phrase here. Writing changelogs manually is tedious, especially for backend/infrastructure changes that users never see but matter a lot. I wanted something that didn’t just rephrase commit messages, but actually understood the code diffs. HOW IT WORKS: - Analyzes diffs from PRs or direct commits - Summarizes the changes using OpenAI (code-diffs+custom prompt + heuristics) - Organizes entries by date or tag - Hosts a live changelog page (e.g. https://magemaker.changeloghub.com, an example changelog for one of my open-source project) - Rebuilds automatically on every push or merge VIDEO DEMO of it in action: https://youtu.be/bntgkZGncZ4 TECH STACK: - Frontend: Next.js - Backend: Node.js, GitHub App (REST + Webhooks), custom worker to spinup a page. Cloudflare for domain routing - Diff analysis: git CLI + a few heuristics to split changes across files and summarize them meaningfully - LLMs: Currently uses OpenAI AI, with batching and retry logic to reduce latency + cost Some use cases: - Solo builders who forget what they shipped, or write too technically (me ) - Teams with frequent infra work that doesn’t show up in traditional release notes - OSS maintainers who want hosted changelogs without managing Markdown files or changelog bots I’d love feedback from other devs: - What would make this more useful for your team? - How should I improve the diff-to-summary heuristics? - Should I support other hosts (GitLab, Bitbucket)? It’s free for one closed-source repo and multiple open-source repos, and I’m planning to keep it indie-friendly. I also plan to send weekly newsletter, similar to launchweek, to highlight the latest releases of projects. So the projects get free eyeballs/marketing. Thanks in advance for checking it out

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
