It retrieves only relevant information when needed, reducing repeated explanations and freeing up tokens for actual coding. The tool supports SQLite, MongoDB, or PostgreSQL as a backend and is free with no subscription required. ## Content Claude Code forgets after every session. So I built **claude-db** to keep the important context outside the context window. It remembers your previous decisions, fixes, patterns, and project knowledge, then brings back only what matters. Less re-explaining. Less repeated context. More useful tokens for actual coding. And you can use your own SQLite, MongoDB, or PostgreSQL database. Free. Open source. No subscription.
