jaq vs JSON Editor

jaq is a free jq clone for querying and transforming data, available as both a command-line replacement and a Rust library for compiling and running jq programs. Alongside JSON, it handles YAML, CBOR, TOML, XML, CSV, and TSV, and can convert between those formats while applying a jq filter. Its jaq-core library supports multithreaded use and data types beyond JSON. jaq also accepts arbitrary values as object keys and can process strings containing arbitrary bytes, including invalid UTF-8. The project publishes benchmarks comparing jaq with jq and gojq, and reports faster results on many benchmarks. It states that jaq is memory-safe and prevents input data or filters from initiating I/O, although filters may read files before execution. The project also warns that it does not guard against resource exhaustion, so processing may use unlimited time, memory, or stack space. Binary downloads and installation instructions are provided for Linux, macOS, and Windows, and an online playground is available. jaq is MIT-licensed.

JSON Editor is a free JavaScript library that generates an HTML form from a JSON Schema. It supports JSON Schema versions 3 and 4, plus some hyper-schema features, and provides validation for the current form value or another supplied value. Themes include HTML, Bootstrap 3, Bootstrap 4, Bootstrap 5, Spectre, Tailwind, and barebones. Optional integrations cover JavaScript template engines, CSS frameworks, icon libraries, and editors such as Ace, SimpleMDE, and SCEditor. You can install the library with npm, load it from a CDN, or download it for local use. It has no dependencies and requires a modern browser; Chrome and Firefox are listed as tested browsers. External schema references are supported, although cross-origin requests need suitable headers or supplied references. The project is in maintenance mode, with active development moved to Jedison. Maintainers continue reviewing community pull requests and handling critical bugs and security issues. The MIT License permits use, modification, distribution, and sale under its terms.
