Sourcegraph Code Intelligence Platform

Sourcegraph is a code intelligence platform that enables developers to search, understand, and fix code across all repositories and code hosts. Founded in 2013 by Quinn Slack and Beyang Liu, Sourcegraph has become the standard tool for large-scale code search and intelligence. Key features: universal code search across all repositories (GitHub, GitLab, Bitbucket, Perforce) and all branches, commits, and codebases, with regex, literal, and structural search. Code intelligence including go-to-definition, find references, and hover across the entire codebase without cloning, powered by SCIP (Sourcegraph Code Intelligence Protocol) and LSIF indexers for precise cross-repository navigation. Batch Changes for automating large-scale code modifications across thousands of repositories using declarative templates and execution environments. Code monitoring for tracking new code matching patterns and receiving notifications when critical code changes are introduced. Insights dashboards for visualizing codebase trends including language adoption, test coverage, migration progress, and technical debt metrics. Code host integration with GitHub, GitLab, Bitbucket Server, AWS CodeCommit, Gerrit, Phabricator, and Perforce via native connectors. Browser extension for enhancing code viewing on GitHub and GitLab with inline navigation, references, and blame. GraphQL API for programmatic access to search results, code intelligence, and repository metadata. Notebook-style code browsing for creating shareable, persistent code explorations. Cody AI assistant for code understanding, generation, and explanation, integrating with LLMs for context-aware code assistance. Single-tenant and cloud deployment options. Used by Uber, Lyft, Cloudflare, Atlassian, and PayPal for managing massive monorepos and distributed codebases.
