Yes, while we are getting started — the first 250 signups get lifetime Pro for free. After that, plans are $59/year or $100 lifetime, no card required to try.

What is the difference between the Free and Pro plans?

The Free plan gives you the core developer tools at no cost. Pro adds unlimited usage, private history, saved snippets, and priority support — all still fully offline on your device.

Your data stays on your device — there is no cloud sync. Vault-style data is additionally encrypted locally with a password only you know.

Do I need an account to use the tools?

Google Sign-In is required to save your data across sessions. Many public tool pages can be explored before opening the full app experience.

Does it work offline?

Yes. MyDevTools is a desktop app — most tools run fully offline on your machine. Tools that connect to external services or send API requests need a network connection.

MyDevTools is the all-in-one desktop developer toolkit that brings together everything you need: a powerful SQL, NoSQL (MongoDB), and Redis database client alongside 80+ utility tools. Stop switching between tabs and apps—format JSON, test APIs, decode JWTs, build regexes, generate UUIDs, and manage databases all in one desktop workspace.

Local-first architecture means your data is processed on your machine and works fully offline. Sensitive credentials are AES-256 encrypted in a local vault. Whether you're testing REST endpoints, debugging database queries, or working with cryptographic tools, everything runs with zero-knowledge encryption—nothing ever leaves your device. Get started free, then upgrade to lock in launch pricing.

Trusted by developers. No ads, no tracking, no data harvesting. Compare MyDevTools to Postman (API client alternative), DBeaver (database GUI), scattered single-purpose websites, and other dev tool platforms—we unify what others scatter across 20 tabs.
