Is tweak free?

Yes! Our free version is used by thousands of users around the world. We've launched a paid plan with additional capabilities but we did not added a single restriction on existing capabilities so that our users can continue to enjoy our product for free.

Do I need to add/install something in my code?

No! No external application/library installation is required! tweak works as a standalone browser extension and you can work with it in any environment, from development to production. No code required!

Will this work in every web application?

Under specific conditions, things might not work at first. For that we advise a page reload after pressing the play/run button to reactivate the extension. If the issue persists please check if our known limitations apply to you and your use case.

How do I report an issue or bug?

Please report it here.

Is this extension safe? I'm concerned about my privacy.

tweak is safe, because we don't store any of your data in remote servers. Everything is stored in your browser.. We do however collect basic google analytics metrics to track the usage of our functionalities for performance measurement purposes. This is mentioned in the privacy policy.

Do I need to keep the devtools open?

Nope 😎  . tweak will still work even if you have the browser devtools closed! However, if you're using tweak for development we do recommend you to keep the devtools opened, with the option "Disable cache" ticked so that you don't get tricked by the browser. For cases where you're doing a demo or doing a screen recording it's understandable that you would want to keep the devtools closed.

When mocking a response it disappears from chrome devtools network tab?

Yes! But don't worry, tweak is designed to work that way. Requests are mocked at the XHR & fetch APIs level, hence it's not reflected on the network panel, however tweak logs a small message in the console for you to keep track of intercepted requests. Once you mock a request it won't be surfaced in the devtools. This is a side effect of our implementation decision which hopefully allows us to have more control and add more features easily as we move forward.

Is there any detailed step by step guide where I can learn how to use tweak?

We highly recommend you to watch this short video. We also have a very detailed documentation page for you to explore later on.
