An index that lets agents search big datasets cheaply

Leviathan, its README says, is a single binary that turns records (JSONL, CSV, SQLite, or a database’s command line output) into a ranked full text index: an agent asks in plain words and gets a few short, cited results instead of grepping raw history. Written in Rust, Apache 2.0.

Score 5 of 9: new 3 of 3, momentum 0 of 3, evidence 2 of 3. Momentum measured: 653 to 653 stars in 0.04 hours (0.0% a day), read 2026-10-07T14:36:32Z. Two minutes apart, too close to show movement; re-check due 9 to 10 October.
