In their own words
BracketView
BracketView is a JSON workspace for viewing, formatting, validating, querying, and comparing JSON in a browser or desktop app. It provides text, tree, graph, node-card, and nested-table views, as well as Stats and JQ tools. Users can query JSON with JSONPath expressions or jq running in the browser through WebAssembly. Validation supports OpenAPI definitions and custom JSON Schema rules, and the workspace can generate types for TypeScript, Python, Go, Rust, and more. Webhook Tester captures requests from services such as Stripe, GitHub, and Shopify. Core formatting, validation, comparison, and visualization run in the browser; optional AI, snapshots, and webhook capture may send or store data on BracketView servers. AI features may send JSON or an excerpt to Groq and/or Google Gemini through those servers. The desktop app runs core tools offline and opens local files up to 200 MB. Web uploads are limited to 5 MB on Free and 50 MB on Pro. The Free plan is $0 forever; paid plans start at $2.25/mo (annual).
jsonfmt.dev
jsonfmt.dev is a web-based JSON formatter, beautifier and validator, with an HTTPS API for JSON processing. The formatter offers 2-space, 4-space or tab indentation, optional key sorting and depth control. It validates JSON against RFC 8259 and reports line and column errors. Other tools can repair common malformed JSON, compare two documents and convert formats including YAML, CSV, XML, TypeScript, SQL, GraphQL and Protobuf. The toolkit also includes a JWT decoder, JSON Schema validator, JSONPath evaluator and JSONL tools. The maker says the core browser tool handles JSON locally without sending its contents to the server, and continues to work offline after loading; it can also be installed as a Progressive Web App. API options include anonymous access limited to 10 requests per minute, a free API key tier with 100 requests per minute and 1,000 per month, and Pro API at $9, paid once for 1,000 requests per minute and 50,000 per month. Share links encode JSON in the URL fragment, and anyone with the link can access its contents.
