BracketView vs JSONZen

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).

JSONZen is a browser toolkit for formatting, validating, comparing, querying and converting JSON. Its tools also include minification, a tree view, JWT decoding and code generation for TypeScript, Zod, Pydantic v2 and JSON Schema. The site says core tools run in the browser and require no signup. Validation supports JSON Schema drafts 07, 2019-09 and 2020-12, with errors reported by path. Queries can use JSONPath and JMESPath; jq querying is listed as a Pro tool. Share links place their payload in the URL fragment rather than on JSONZen’s servers. Free share links allow up to 32 KB, and Free users can store three snippets locally per browser. Pro adds encrypted cloud-synced snippets, with manual syncing per snippet and a 2 MiB ciphertext limit per snippet. The listed Free plan is free, billed Forever. Pro is listed at $1.00 USD once for 30 days as a launch promotion, with no auto-charge; the pricing note lists paid plans from $5/mo. The CLI is included free.
