Why codedb

Index once, query forever

Trigram search

Pre-built index. No filesystem scan per query.

Structural parsing

Functions, structs, imports with line numbers.

Dependency graph

Reverse import tracking across all files.

Word index

O(1) hash lookup for exact identifiers.

File watcher

Re-indexes changed files in under 2ms.

Multi-agent

File locking and heartbeats. Safe concurrent access.

Zero dependencies

Pure Zig. Single binary. macOS + Linux.

Snapshots

Instant MCP startup. No re-indexing on restart.
