Sourcebot, an open-source Sourcegraph alternative
Hi HN, We’re Brendan and Michael, the creators of Sourcebot (https://github.com/sourcebot-dev/sourcebot). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4, or try it for yourself on our demo site here: https://demo.sourcebot.dev While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases…
Sourcebot, an open-source Sourcegraph alternative launched on October 1, 2024 with 259 votes, #157 of 5,185 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Sourcebot is an open-source code search tool designed for developers who need to search across multiple large codebases simultaneously. Created as an alternative to Sourcegraph, it indexes codebases in the background and provides a web-based search interface, addressing the limitations of command-line tools like grep when working with hundreds of multi-million line repositories. The tool is available on GitHub for self-hosting.

Talanoa▲340Hi 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…
