The original json formatter getting sold and turned into adware is honestly the worst, so glad someone made a clean replacement. Tried it on a gnarly 50mb file and it didn't choke, which is kind of unheard of.
@mustafagfvx Thank you for testing it on a 50MB file! That's exactly the use case that motivated the Pro tier — the old formatter would freeze the entire browser tab on anything over a few MB. The Web Worker streaming parser is the secret sauce here. No JSON is too large. Appreciate you giving it a real stress test!
@mustafagfvx Really appreciate that. Watching the original tool go down the adware route was honestly heartbreaking, so keeping this one clean and user-respecting was non-negotiable from day one. And wow — 50MB is no joke, most browser-based formatters fall over way before that. Really glad it didn't choke on you. Performance was a big focus for us.
Love that this exists as a clean alternative to the mess the old formatter became. One thing I'd love to see: a side-by-side JSON Schema view where you can paste a schema and validate the formatted JSON against it inline, highlighting mismatches as you type.
@emircansowj Great suggestion, thank you. JSON Schema validation is on my radar — being able to paste a schema and see inline validation errors would be super useful for API debugging. It's a bigger feature (schema resolution, draft support, etc.) so I want to get it right. Curious — which JSON Schema draft do you usually work with?
@emircansowj Really appreciate that! The old tool definitely got bloated over time, so keeping this one clean and focused was the goal. And love the schema validation idea — inline, side-by-side, with live highlighting as you type. That's exactly the kind of frictionless workflow we're after. No ETA yet, but it's on the list now. Thanks for the solid suggestion!
the offline-only promise is exactly what i want from a json tool, love that jwt decoding happens inline without bouncing the token somewhere else. solid execution all around.
@idemfxp1 That's exactly why I built it this way. Most JWT tools are web-based and send your tokens to a server for decoding — which defeats the whole point of local-first. Glad the inline decode + offline promise resonated with you. Thank you!
@idemfxp1 Thanks! That's the whole idea — your data never leaves your machine, period. Glad the inline JWT decode and the offline-first approach hit exactly what you were looking for.
Love that it stays fully local with zero network requests, that's a real trust signal people actually care about. The JWT auto-decode inline is a nice touch too, saves a tab hop.
@muratzgirgr6bi "Zero network requests" is both a feature and a promise. A lot of developers are tired of tools that phone home — even anonymously. And the JWT decode inline was one of those "why doesn't every JSON viewer do this?" features. Glad you find it useful. Thanks for the kind words!
@muratzgirgr6bi Really appreciate that. We figured the best privacy policy is "we literally can't see your data" — zero network requests means zero ambiguity. And yeah, inline JWT decode was one of those "small but annoying" friction points we wanted to eliminate. Glad both are hitting the mark!
