BracketView is fantastic because it combines an entire JSON toolkit into one free, browser-based app — no installation needed. The AI JSON Fixer instantly repairs broken JSON (missing commas, unquoted keys, trailing commas) with one click, saving significant debugging time. The multi-language type generator (9 languages including TypeScript, Python, Go, Rust) is a rare feature that eliminates manual boilerplate. The JQ Filter playground lets you run powerful queries without setting up anything locally. Add in real-time validation, tree visualization, schema tools, diff comparison, and encrypted snapshot sharing — it genuinely replaces 5–6 separate tools developers normally juggle.
