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.

Does API Client store or upload my data?

API Client runs in the MyDevTools desktop app. Many utilities process data locally on your device; tools that require sync or external connections may send only the data needed for that workflow.

Do I need to install anything to use API Client?

Install MyDevTools once, then API Client and 80+ other tools are available offline on your desktop.

About API Client

Test and debug HTTP requests with headers, body, and auth support. A lightweight Postman alternative for your desktop. Part of MyDevTools — an all-in-one desktop toolkit that runs offline and processes your data locally on your machine.

Common API Client use cases

Use API Client when you need a fast, dedicated way to work with api client. It is useful during API debugging, code reviews, documentation cleanup, test data preparation, and quick checks. Because MyDevTools keeps related utilities together in one offline desktop app, you can move from API Client 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 API Client. 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 API Client part of a practical developer workflow instead of a one-off utility page.
