A modern runtime for JavaScript and TypeScript.
elliptic-curve
Counted from the Cargo.toml manifests of the 34 indexed repositories that declare elliptic-curve as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in elliptic-curve 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 elliptic-curve projects that also use it.
Servo aims to empower developers with a lightweight, high-performance alternative for embedding web technologies in applications.
Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
LLRT (Low Latency Runtime) is an experimental, lightweight JavaScript runtime designed to address the growing demand for fast and efficient Serverless applications.
