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 JSON Visualizer store or upload my data?

JSON Visualizer 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 JSON Visualizer?

No installation required. JSON Visualizer runs directly in your web browser — just open the link and start using it.

Common JSON Visualizer use cases

Use JSON Visualizer when you need a fast, browser-based way to work with json visualizer. It is useful during API debugging, code reviews, documentation cleanup, test data preparation, and quick checks on a new machine where you do not want to install a desktop app. Because MyDevTools keeps related utilities together, you can move from JSON Visualizer into nearby tools like formatters, converters, generators, encoders, decoders, and API helpers without leaving the same toolkit.

Example workflow

A typical workflow starts by pasting or typing your input into JSON Visualizer. Review the result, copy the cleaned or generated output, then continue with a related task such as validating a payload, decoding a token, parsing a URL, generating an identifier, or testing an API request. This makes JSON Visualizer part of a practical developer workflow instead of a one-off utility page.
