# sqlx vs union

sqlx and union share 7 technologies: sqlx, sqlx-postgres, Postgres, SQLite, Tokio, console, and tracing. Both are written in Rust.

- [transact-rs/sqlx](https://seerepo.com/r/transact-rs/sqlx): 🧰 The Rust SQL Toolkit. An async, pure Rust SQL crate featuring compile-time checked queries without a DSL. Supports PostgreSQL, MySQL, and SQLite.
- [unionlabs/union](https://seerepo.com/r/unionlabs/union): The trust-minimized, zero-knowledge bridging protocol, designed for censorship resistance, extremely high security, and usage in decentralized finance.
