Auto-fix your GitHub PR issues with Proton for FREE
Hey HN! We just launched Proton, a GitHub app that listens to PR review comments and suggests code changes to address them. It creates a new PR based on top of your working branch, so you can simply review and merge. How is it different from other AI code review tools? Others focus on pointing out issues, whereas Proton focuses on addressing them. Although some of them can also suggest fixes, they tend to only work on nearby lines or within a single file. But real-world feedback often involves cross-file changes like “Let’s extract this to a separate component”, or “We should follow the same…
Auto-fix your GitHub PR issues with Proton for FREE launched on April 29, 2025 with 10 votes, #3,208 of 7,818 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Proton is a free GitHub app that automatically generates code fixes in response to pull request review comments. When reviewers suggest changes, Proton analyzes the feedback and creates a new pull request with proposed modifications that developers can review and merge. Unlike similar tools that flag issues or suggest fixes within single files, Proton understands full repository context to handle cross-file changes and complex refactoring requests that reflect real-world code review feedback.

- FBFile-by-file AI-generated comments for your codebase2023 · swiftstart.vercel.app · ▲51
My friends and I were complaining about having to decipher incomprehensible code one day and decided to pass the code through GPT to see if it could write easily understandable comments to help us out. It turns out that GPT can but it was still a hassle to generate comments for large files. So we decided to develop a basic web application that automatically integrates with your Github repository, generate comments, create a pull request and send you an email when it is all done. There is definitely a lot more that can be done but we wanted to gain feedback on whether this is a problem that…

GitReviewed2025 · gitreviewed.com · ▲18Hi HN, I’m Valentin, a developer who’s found code reviews to be a slow process, especially after context switching or juggling different projects and languages. Even reviewing my own code can be tough when I’ve lost the thread or just need a fresh perspective. Over the past few weekends, I built GitReviewed to make PR reviews faster, smarter, and genuinely useful for real teams. What it does: - Reviews any GitHub or GitLab pull/merge request with AI-powered comments, spotting security issues, code patterns, typos, and more - Posts comments as you (not a bot), so feedback fits naturally…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
