Self-hosting is free forever — clone the repo, deploy it yourself, no fees, no limits from us. The hosted cloud (mydevtools.tech) is a paid service.

What is the difference between self-hosting and MyDevTools Cloud?

Self-hosting is the same codebase running on your own infrastructure — you own the data and pay nothing to us. MyDevTools Cloud is our managed service; it is a paid subscription that covers hosting, sync, and backups.

Sensitive data is encrypted in your browser before it reaches the server where supported. The server stores encrypted blobs for vault-style data instead of readable plaintext.

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.

Is this truly open source?

Yes. Full source code is available on GitHub under the GPL-3.0 license. You can audit, contribute, fork, or self-host it.

Does it work offline?

Many tools are fully client-side and can work without server processing. Tools that connect to external services, sync data, or send API requests need a network connection.

MyDevTools is the unified developer toolkit that brings together everything you need: a powerful SQL, NoSQL (MongoDB), and Redis database client alongside 60+ utility tools. Stop switching between tabs and apps—format JSON, test APIs, decode JWTs, build regexes, generate UUIDs, and manage databases all in one workspace.

Privacy-first architecture means your data is processed in your browser whenever possible. Sensitive credentials are AES-256 encrypted before sync. Whether you're testing REST endpoints, debugging database queries, or working with cryptographic tools, everything runs with zero-knowledge encryption. Self-host for free or use our managed cloud with paid subscription.

Open source (GPL-3.0), fully self-hostable, and trusted by developers. No ads, no tracking, no data harvesting. Compare MyDevTools to Postman (API client alternative), DBeaver (database GUI), single-purpose online tools, and other dev tool platforms—we unify what others scatter across 20 tabs.
