jaq

A high-performance, Rust-powered jq clone that delivers precise JSON parsing with zero external dependencies.

Built to solve the startup lag and edge-case bugs of traditional jq, jaq is a lightweight, syntax-compatible replacement written in Rust. It launches up to 30 times faster than older jq versions, making it ideal for processing thousands of small files in rapid succession. Beyond raw speed, jaq fixes long-standing correctness issues in filter limits and arithmetic operations, while expanding its utility with native support for YAML, TOML, and XML. Developers can drop it directly into existing shell pipelines or integrate its core library, jaq-core, safely into multi-threaded Rust applications.
