Sourcegraph

Sourcegraph turns your entire codebase into something you can query: it indexes code scattered across hundreds of repositories into a search index and a code graph, then runs search, question answering and automated code changes on top of that index. It is not a completion plugin inside an IDE; it is an enterprise foundation for platform engineering, SRE and security teams.

Core capabilities

• Cross-repo code search: exact, deterministic and exhaustive search across hundreds of repositories and huge monorepos, with regex, symbol and dependency tracing
• Deep Search: ask in natural language and the agent reads code and commit history across repositories, returning answers with cited sources
• Agentic Batch Changes: describe a change in one sentence and the agent scopes it, applies it in bulk and tracks it through to merge
• MCP server: exposes cross-repo code context over the Model Context Protocol to external agents such as Claude Code, Cursor and Codex
• Insights and monitoring: turns code metrics into dashboards so migration progress and standards adoption stay visible

Where it fits Platform engineering, SRE and security teams whose repository count no longer fits in anyone's head; inherited systems where you must trace the call chain; cross-repo vulnerability fixes, bulk framework upgrades and audits that need an answer to who else is still on this version.

What sets it apart An IDE assistant sees one repository at a time; this index spans all of them, so a question touching ten services comes back as one answer instead of ten tabs. It also exposes that context over MCP, so external agents read the same code graph. On the enterprise side it offers single-tenant cloud or self-hosting, SSO and SCIM, and zero data retention.

Editor's take It is neither cheap nor freemium: after the self-serve plans closed in 2025 only the enterprise edition remains, starting at $16K a year and sold through sales. Individual developers who want similar agent capabilities are pointed to Amp, now a separate company. It earns its price in organizations with many repositories, many cross-repo questions, and code that cannot leave the internal network.
