What it does

Open-source AI code review for GitHub, GitLab (cloud + self-hosted), Bitbucket, Azure DevOps, and Gitea. Written in Rust. Bring your own key. No data leaves your infrastructure.

Merlin AI Code Review reviews every pull request with configurable AI — inline comments, security scans, docs generation, and an autonomous agent — without sending code to a third-party SaaS. Written in Rust 🦀 for maximum performance. env::var() is called per-request. Cache via once_cell::sync::Lazy to avoid repeated env lookups under load. Drop a single GitHub Actions step (or GitLab CI job). No server to run, no signup required. Merlin AI Code Review triggers automatically. It reviews the diff in parallel chunks and posts inline comments sorted by severity. Bugs caught, docs generated, tests suggested. Every PR reviewed as if your best engineer was watching. One binary. Drop it in any CI…from merlin-review.com

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
