Sourcegraph went private; this repo is its fossil record

What it does

Sourcegraph is a code intelligence platform built to search, navigate, and refactor code across sprawling, multi-repository codebases. This specific repository is a static snapshot captured just before the company migrated all ongoing work to a private monorepo. It preserves the Go-based architecture, GraphQL APIs, and internal documentation exactly as they existed at the transition.

The interesting bit

Most commercial projects vanish quietly into private repos; Sourcegraph at least left a clearly labeled time capsule, including a pinned final commit still licensed under Apache. That makes this less of a ghost town and more of a formal archaeological site for a tool that once defined the category.

Key highlights

• Read-only snapshot of the pre-migration codebase, spanning global code search and cross-repository refactoring tools
• Final Apache-licensed commit explicitly marked for anyone continuing open-source forks
• Current snapshot carries a primarily non-OSS commercial license, so the legal landscape changed after that last commit
• Extensive internal developer documentation survives intact, from architecture overviews to database best practices
• 10,289 stars at time of writing, making it a prominent case study in the lifecycle of commercial developer tools

Caveats

• Active development, bug fixes, and new features have moved elsewhere; this is strictly a historical reference
• The repository is no longer under a permissive open-source license, despite the historical Apache commit remaining accessible
• Features and integrations are frozen at the migration point, so expect growing staleness against modern code hosts

Verdict

Developer-tool historians and anyone maintaining a fork from the last open-source commit should dig in; teams needing a living, evolving code intelligence platform should evaluate the current commercial offering instead.
