A complete browser-based toolkit for developers — format JSON, encode Base64, test regex, convert colors, generate cryptographic keys, parse cron expressions, and more. Every tool runs entirely in your browser with no installation, no account, and no data ever sent to a server.

Seventeen tools shaped by the workflows of working developers — no fluff, no upsell, no signup wall between you and the answer. The cryptography suite uses the native Web Crypto API; the JSON tools handle million-byte inputs without freezing the tab; the regex tester highlights matches as you type; the JWT decoder verifies signatures across HS, RS, ES and EdDSA in one place. Every output flows into the next compatible tool via a one-click Send to…, so the seventeen feel like one connected workspace rather than seventeen tabs you have to keep arranged.
