Launch YC: Sourcebot: The Code Understanding Platform

"Sourcebot is a self-hosted platform that helps humans and agents answer questions about your code."

TL;DR: Sourcebot is an open source code understanding platform. It’s used by thousands of engineers in some of the largest companies in the world (including NVIDIA, Red Hat, Wikimedia, and Arista Networks) to help developers and AI agents understand massive codebases.

Founded by Michael Sukkarieh & Brendan Kellam

Brendan and Michael met 10 years ago during their first week at McGill University 🇨🇦. They were both into game engines, which led them to work at Ubisoft Montreal on the largest game engines in the world. Afterwards, they worked on some of the most complex systems out there: Visual Studio at Microsoft, a cloud-first game engine at Google, VR operating systems at Meta, and cloud-streaming infrastructure at Xbox. Ramping up and understanding these systems was always a long, painful process - which is what led them to build tools to help developers understand this complexity.

The problem:

  • Large engineering teams manage millions of lines of scattered and undocumented code.
  • Individual engineers must regularly find and understand code across this complex environment to do their job. Existing tooling to do so is inadequate, rudimentary, and often nonexistent.
  • AI agents have this problem too. They need this context to provide usable results within an enterprise environment

The solution:

Sourcebot solves this by providing the following tools:

  • Code Search - instantly search across millions of lines of code. Supports regex, boolean logic, and repo/file/branch filters.

  • Ask - ask questions in natural language across thousands of repos. Like asking in Cursor, but across all your repos and in a web app with inline citations.

  • MCP - gives both of the above tools to AI agents, allowing them to fetch context from code across your organization.

Additional features:

  • They integrate with any code host (e.g., GitHub, GitLab, BitBucket, etc.) as well as any LLM model (e.g., OpenAI, Anthropic, Bedrock, etc.). Bring your own LLM key.
  • Sourcebot is open source and self-hosted - none of your code leaves your deployment. Deploy and index all your repos in minutes with a single docker container.
  • They have a community edition that’s free to use, and a paid enterprise edition with advanced navigation features, analytics, and security/compliance features.
