tweak your HTTP requests

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.

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

Absolutely not! 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?

tweak has proven to be reliable, but still we acknowledge our 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.

I clicked on the file import button but nothing happened?

In case this happens, close the popup, go back to your website, refresh the page, and give it another try. To import, you must be on a webpage (e.g. http(s)://...). If you're for instance on the chrome/firefox settings page, (e.g. chrome://settings) you won't be able to perform the import.

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.

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. 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?

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

Does tweak support window.fetch?

Yes! tweak supports both window.fetch and XMLHttpRequest (XHR).

Does tweak work on iframes?

We've introduced partial support in tweak v1.1.0, it's currently something has a great coverage, therefore we acknowledge that it might not work for most the use cases. We advise to open the iframe in a separate browser tab to operate on it, if possible.

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

tweak is as safe as they come, simply because we don't store any data you input. Everything is stored in your browser We simply collect basic google analytics metrics to track the usage of our functionalities to better serve our users. This is mentioned in the privacy policy.
