Hi HN! We were frustrated with text diffs on GitHub PRs, so we made DiffLens (https://github.com/marketplace/difflens). DiffLens constructs an Abstract Syntax Tree for each file, and uses that semantic information to intelligently diff changes. Checkout the demo on our website (https://www.difflens.com). Getting started with DiffLens is easy! Simply install the app on your repositories. The next time you open a PR, DiffLens will automatically create a diff for your changes. If you review code, especially TypeScript, JavaScript or CSS, give DiffLens a try! We're…

A few friends and I noticed that many PRs are easier/quicker to review if the changes are reviewed in some order other than alphabetical by filename (which is the default in Github). So, we'd often write our PR descriptions to include a suggested review order: "review file xyz.py first, then abc.js, then foo.rs". We did this often enough that we built a chrome extension that lets us reorder diffs in the Github PR UI rather than needing to type out the suggested order in the description. Anecdotally, we've noticed that using this tool to reordering diffs makes it much easier for…

Pipe the output of a `diff` command to Diffswarm to get back a persistent URL that contains the diff with workflow, comments, search, etc. Basically some of the helpful features that Github offers on PR diffs, just available for any arbitrary diff. I wrote this tool to use at work for documenting snapshot diff triaging, and also used it to help with the same thing on a couple Ty PRs. Example: https://diffswarm.dev/d-01k2gknwyq82f6x17zqf3apjxc

Hi HN, Lately Github PRs have been drowning in a flood of AI slop. I’ve been seeing it myself, and I’m not the only one: https://x.com/mitchellh/status/2011819428061855915 I think it’s great that folks are using AI tools to code faster and better, but too many folks are abusing them to make low-quality contributions to public repos. This takes a lot of reviewers’ mindshare. IMO there needs to be a mechanism to flag low-effort PRs with AI slop, so you can just skip reading them. So I built one: https://haystackeditor.com/slop-detector It’s a simple AI…

Plannotator opens a local diff viewer (git, jj, p4). You annotate lines, tokens, or comment on files, and when you're done they feed straight into your agent session; creating an automated feedback loop. It works on local diffs, commits, branches, worktrees, and GitHub/GitLab PRs. The PR view lets you annotate the descriptions and comments while also being able to filter bot comments. The core tool enables focused manual review, the optional AI layer: - Ask AI: Ask questions directly inline - Guided Reviews: Have an agent reorganize a large diff into semantic overview sorted by…

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

Hey HN! I'm Hussam, a Senior Algorithm Engineer at CodiumAI. We launched PR Agent a little over a year ago — it’s a free and open-source tool that helps with reviewing pull requests. The response has been great and more than 70 contributors have added to the project. Today, we're launching PR Agent as a browser extension. Key features: - AI Chat in PRs: You can ask questions about specific code changes and the context is passed to the AI model - Automated Code Reviews: The /review command does an automated review, focusing on potential bugs, security issues, and best practice violations…

I built a CLI that detects patterns AI coding tools leave behind: empty catch blocks, hardcoded secrets, as any everywhere, comments that restate the code, god functions, SQL concatenation. 24 rules across JS/TS and Python. Zero config, runs offline, regex-based so it's fast. npx @yuvrajangadsingh/vibecheck . Also ships as a GitHub Action for inline PR annotations and standalone binaries (no Node required). Why: CodeRabbit found AI-generated PRs have 1.7x more issues than human PRs. Veracode says 45% of AI code samples have security vulnerabilities. "Vibe coding" is everywhere now…

Hi Everyone, I made an open-source GitHub bot that automatically submits a detailed line-by-line code review instantly on any new PR. It's just one-click install to get started. You can host your own bot if you'd like. Open for feedback. thanks!

Hey HN - We're building wispbit (https://wispbit.com/) - a tool that lets you build your own AI code reviewer. We built this because we worked in big and complex codebases where we kept hitting booby traps - often the same ones. People forgot things, or quit altogether, amplifying the problem. We looked for other ways to fix this, but the solution is usually a combination of: - Writing a linter rule - too difficult and time consuming. - Writing docs and having frequent meetings on alignment - basically a full time job. - Using plug and play code reviewers - too generic and…

Prepend any Github PR URL with `makesense` to get a - quick review for all sorts of issues (cleanly designed issue explorer) - summary of changes in concise slide deck to grasp the essence of changes - a 5 question quiz on the changes to make sure there's "cognitive coverage" of the change There's also a handy bookmarklet using which you can trigger a review for any publicly accessible Github PR Feedback welcome

I built this because I was tired of creating pull requests in 20 repositories just to change a single line of workflow job version. With Infra as AI, just mention the change. Agents work on all repos in parallel, read the docs, make a bunch of PRs and fill in the description. You can see the demo of the actual dashboard in the landing. Let me know your thoughts :) It means a lot to me!

Hey again HN. Isaac and I originally released a voice-first code review tool, but have since open-sourced it and turned it into just a better way to review your and your team's Github PRs. Main things we've heard that make code reviews slower are: 1) PRs are too big and overwhelming 2) Need to jump around to find the right context and relevant code 3) Need to spend time thinking (should not be a thing since AI exists), and writing comments What we built to address these: 1) PRs are split up into sub-PRs without needing to actually split them up and stack them yourself -> Automatically done…

I've created uithub, a tool that allows developers to easily get LLM context for their coding questions and perform AI repo analysis at scale. Here's what it does: - Get Context: Simply change the 'g' in github.com to 'u' to access AI-powered insights on any GitHub repo. - Flexible Querying: Fetch entire repos, specific branches/subfolders, or filter by file type and size. - API for Developers: Power the next generation of development tools with our API. Key features: - Customizable token limits - File type filtering - Multiple response formats - Size-based file exclusion I built this…

I built a CLI tool that turns codebases and PRs into diagrams so you can quickly understand how things fit together. Originally made it because I couldn't follow my own AI-generated repos. Just shipped a big update: - Switched from D2 to Mermaid for rendering - Tree-sitter AST parsing + agentic flow instead of raw LLM calls. ~50x faster. - Works on any GitHub repo or PR, not just local - Dropped the web frontend, it's just a CLI now - Published as a pip package Still a ton to improve and I'm building fast. Feedback, issues, PRs all welcome.

Hey HN, Over the last year, I’ve reviewed more than 1000 code changes. Most of the time was spent catching obvious mistakes rather than debating complex design decisions. If we estimate ~10 minutes per review, that’s 160+ hours spent reviewing code in just one year. So I thought: could I get some of that time back using LLMs? That's why I spent the last few weekends building Presubmit.ai, an open-source AI reviewer that runs as a Github Action right when you open a Pull Request. The results so far are promising: I estimate it can reduce the review time by 50%, which in my case would mean I…
