jaq is a clone of the jq JSON processing tool written in Rust, focused on correctness, speed, and simplicity, usable as a drop-in replacement for jq. It also ships as a Rust library (jaq-core) for compiling and running jq programs, with support for YAML, CBOR, TOML, and XML data formats.

Use cases

• query and transform json from the command line
• faster drop-in replacement for jq
• run jq filters inside a rust program
• process yaml, toml, cbor, or xml with jq syntax
• batch-process many small json files quickly

When to choose

• you want jq-compatible filtering with better startup time and performance
• you need to embed a jq interpreter in Rust, especially multi-threaded code
• you need jq-style queries over non-JSON formats like YAML or TOML

When to avoid

• you rely on jq features or plugins jaq does not implement
• you need exact jq bug-for-bug compatibility
• you prefer the canonical jq implementation and its ecosystem
