Code discovery

Navigate, explore, and understand the code you are looking for, even if you didn’t know it existed.

Code navigation and exploration

Find answers faster, across any codebase from one centralized place.

Powerful, easy search

Just type your query into Sourcegraph, and it'll find matches. It supports regular expressions, punctuation, exact matches, and much more. Use the visual query builder to narrow down your search and get familiar with search syntax for next time.

Super-optimized for speed

Find what you're looking for in a few hundred milliseconds, even across 10,000s of repositories or in a massive 40 GB monorepo. We're maniacal about making Sourcegraph fast. You can also quickly refine your search using suggested filters, to narrow down results by repository, language, directory, or custom scopes.

Explore definitions & references, even across projects

Find the definition or callers of functions and anything else in code, even across package, dependency, and repository boundaries. Even if your IDE can do this, Sourcegraph lets you explore code intelligently in your web browser in any repository on any branch, instantly and without losing your local context. Works for 32 programming languages.

Search in diffs to find what changed or broke

Look through diffs and commit messages to see recent changes related to a specific function or error message. DevOps teams and SREs find this especially useful when responding to incidents, to find out what code changes might be responsible and who to loop in.

All branches & commits, always up-to-date

Other code search tools limit you to searching a single branch and often have stale results from hours ago. With Sourcegraph's hybrid search (combining indexed and on-the-fly), you can search any branch and any commit. The code is always up-to-date, and you never need to wait for indexing.

Open source, self-managed, & privacy-respectful

Sourcegraph is self-hosted, so your code never leaves your network. And it's open source (Apache 2.0), so you can verify this. (If you prefer not to self-manage your instance, we offer cloud-managed deployment, too.)

How does code search help?

Google developers use code search 5-10 times daily (Table 1 in Google's internal code search research study). Sourcegraph Universal Code Search users report similar use cases and frequency.
