Turso is an in-process SQL database, compatible with SQLite.
loom
Counted from the Cargo.toml manifests of the 41 indexed repositories that declare loom as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in loom projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of loom projects that also use it.

VelesDB is a local‑first AI data engine written in Rust that unifies vectors, full‑text and graph in a single file with a familiar SQL‑like language. Instead of sending every RAG or semantic search query to a remote cluster, VelesDB runs directly on your server, laptop, browser, mobile or edge device — no cloud dependency, no external services, ..
