sourcegraph-public-snapshot

Sourcegraph is a platform that helps developers search, read, and understand code across large collections of repositories. Rather than digging through individual files or relying on a single editor, it lets a team point Sourcegraph at all of their code, no matter how many repositories or hosting services they use, and then search everything at once. Results include the actual code lines, the branches those lines appear on, and navigation links to related definitions and references.

The three main features are code search, code intelligence, and large-scale refactoring. Code search covers all branches and all connected code hosts simultaneously. Code intelligence goes deeper: it shows where a function or symbol is defined, where it is called, who owns the relevant file, and the history of how that code changed over time. The refactoring tools let a team roll out the same change across many repositories at once and monitor progress, which is useful when updating a dependency, renaming something, or applying a security fix organization-wide.

Sourcegraph can be used as a hosted service at sourcegraph.com or installed on a company's own servers for teams that need to keep their code internal. The project is written mainly in Go. The README notes that this particular repository is a public snapshot taken just before Sourcegraph moved to a private monorepo, so the code shown here reflects the state of the project up to that point rather than ongoing active development. The last commit under an Apache License is also marked in the repository for anyone interested in the open-source history of the project.

The README is brief and points to external documentation for setup, architecture, database practices, and contribution guidelines. There is an active community Discord and a public code search instance at sourcegraph.com/search where anyone can try the search feature on open-source code without installing anything.
