Privacy

Privacy-first. Your data is processed locally in your browser and is never uploaded to our servers.

iZZi DevTools collects the small utilities every developer reaches for — JSON formatting and validation, Base64 and URL encoding, JWT inspection, UUID and password generation, text diffing, timestamp conversion and SQL formatting — on fast pages with no sign-up. Each tool runs entirely in your browser, so the data you paste never touches a server.

Fast, free, privacy-first developer tools. Format JSON, decode JWTs, generate UUIDs and more — everything runs in your browser.
