FAQs

How does this thing work?

Fair question. Straight to the point. Don't worry, it won't take you more than 2 minutes to start being productive with tweak: watch this short video.

Will this work in every web application?

No. tweak has its own limitations, currently:

It will only apply the configurations to the browser tab where you configure the requests to intercept and activate the extension (by clicking the run button).
Under specific conditions combined with the asynchronous nature of the way tweak communicates with your website, things might not work at first. For that we advise a page reload after pressing the play/run button to active the extension.

I setup everything, but no requests are being intercepted.

Have you tried to turn it off and on? 🤞 Please refer to the question "Will this work in every web application?" to understand tweak limitations.

Do I need to keep the DevTools open?

No you don't 😎. tweak will still work even if you have the browser DevTools closed! However, if you're using it for development purposes we recommend you to keep the DevTools opened so that you don't get tricked by the browser cache. 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.

Any thoughts on having a tailored support for GraphQL?

We're seriously considering having something in the extension very tailored to GraphQL to intercept requests that interact with GraphQL servers. Send us an email to help.tweak@gmail.com expressing your interest. In the meantime you can still intercept a specific GraphQL by specifying the right request body, you can watch this short video to learn how to intercept a request with a specific request payload (request body).

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

Glad you asked. We drafted a very detailed documentation page for you with some awesome video content.
