Early tester access
Help shape CodePrettify. Use it for $0.
CodePrettify is growing through feedback from the people who use it. Free for everyone who installs now as an early tester: every currently shipped feature in the browser extension or Windows app is available for $0—without a trial, subscription, payment details, or account.
Use either product or both. If something breaks, feels slow, or could be clearer, your feedback helps decide what we improve next.
For early testers
The complete product—not a restricted trial
You get every feature currently shipped. We get feedback from real workflows. Try it on real code and data, and tell us what should work better.
Inspect and validate
Use diagnostics, statistics, JSON Path, Table View, Schema Validator, timestamp helpers, and the local security scan.
Convert and compare
Run 18 JSON, XML, CSV, YAML, TSV, Base64, and URL transformations, compare documents, then copy or export the result.
Test and request
Work in the JavaScript and Regex Playgrounds or compose a deliberate network request in the built-in HTTP Client.

Questions answered
Pricing FAQ
Is early-tester access really free?
Yes. Early testers who install now can use every current feature for $0. Today’s browser extension and Windows app have no trial timer, checkout, subscription, or paid-feature gate.
What do you expect from an early tester?
Nothing formal. Use CodePrettify on real work and send feedback when something breaks, feels slow, or could be clearer. Feedback is welcome, not required.
Are both products free?
Yes. Install the browser extension, Windows app, or both for $0. Their features differ because they support different workflows.
Do I need an account or payment details?
No. Install from the Chrome Web Store, Microsoft Edge Add-ons, or Microsoft Store and start using it.
Does my document leave my device?
Core formatting, validation, conversion, comparison, inspection, and playground processing stay on your device. The HTTP Client makes a network request only after you press Send, to the URL shown in its request composer. Read the privacy policy for the complete details.
Could pricing change later?
The CodePrettify products and features offered here are $0 for early testers who install now. Future optional products, services, or feature tiers may be priced separately, and any change will be communicated clearly.
