Your agent can grep, glob, and read your local codebase. It still cannot do the same thing across the open-source code your app depends on.

That is where it breaks: niche integrations, undocumented APIs, version-specific behavior, and dependency internals. It starts guessing, retries small changes, then pushes the developer back into search, documentation, forums, and trial-and-error.

GitHits builds a version-aware index of open-source code, package internals, documentation, dependency graphs, vulnerabilities, changelogs, and package upgrade changes so agents can retrieve and navigate the actual code running in the stack.

It gives them

• Examples based on prior art from repositories, issues, discussions, and pull requests, linked back to the implementation code.
• Code navigation across packages and repositories: search, grep, list files, and read exact line ranges without cloning.
• Documentation access across hosted docs and repo-backed docs.
• Package inspection for dependencies, vulnerabilities, changelogs, and version-to-version upgrade changes.

• AI-native software engineers using AI coding tools daily, developing greenfield products
• AI coding agents (Cursor, Claude Code, Copilot, etc.)
• Teams building AI-assisted development workflows
