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
