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.

Does Text Diff Checker store or upload my data?

Text Diff Checker is designed for browser-based use. Many MyDevTools utilities process data locally; tools that require sync or external connections may send only the data needed for that workflow.

Do I need to install anything to use Text Diff Checker?

No installation required. Text Diff Checker runs directly in your web browser — just open the link and start using it.
