Description from store
Mokku helps user by mocking API and changing their response, response time and status, user can try all test case scenario like long loading time, error states, or any missing or incorrect data.
Mokku adds itself as a tab in dev tools as a panel. In the tab user can see network logs and mocks. Any network call from the logs can be mocked by simply clicking mock button then response can be edited. User can also search logs. Mock can also be created from scratch from create mock button.

Dynamic URL Mocking
URL such as

2. "service/some/thing/(.*)" can also be added, (.*) will match anything just like the above.
All URL's are accessible but Mokku doesn't inject scripts into any pages apart from which are served locally and accessed using 'http://localhost*'; until enabled from the Panel.
Collections & Dynamic mock generators coming soon!

- (2025-06-11) Subhadip Pal: Best mocking tool, thank you Developer
- (2025-03-13) Dana Mulder: Works as expected!
- (2025-02-13) Marcos Avila: How can I make a backup? I don't see any option
- (2024-10-16) Marko Rajevic: Is this Extension safe, I see that put some inject.js script that makes calls to my API?
- (2024-06-24) Голос Разума: Disgusting. First, the developer decided to completely hide the source code of the extension, but now he has started inserting advertisements without users’ permission. Better use the free and fully open source mockiato extension.
- (2024-06-13) Natalia Díaz Palacios: awesome app! easy to use! the only thing is that is presenting an issue when 204 status is thrown
- (2024-05-24) Chris Weller: Avoid like the plague - a developer that's willing to injects ads into your Google homepage without warning will likely do far worse in the future. EDIT: I've created an ad-free fork, available on GitHub under "MokkuReborn". Please support Mukul with donations if you opt to use the ad-free version. https://github.com/itsWeller/MokkuReborn
- (2024-05-24) Asman Umbetov: The extension injects ads into the Google pages
- (2024-05-24) Lukas Schmid: It WAS a great extension. Shows now ad on google search result. What a shame.
- (2024-05-23) Misael Freitas: Muito boa para o que foi feita para ser usada. Porém comoçou a enfiar ads na pesquisa do google Então ja não recomendo mais.
- (2024-05-23) Clara Griveau: Was great but deleted it now that it triggers ad on my google search
- (2024-05-22) Gökberk Karaca: I removed this extension since it displayed an advertisement on my Google searches without my permission, and didn't mention the source of the advertisement
- (2024-05-22) Tyler Charlesworth: Adware!! Recently has begun injecting probably harmless but unexpected and unadvertised ads into Google search results. Generally, Chrome extensions with high levels of browser access are big security risks and it is VERY concerning to see an extension exhibiting unexpected behavior. This was a helpful extension once in a while and if the description noted this ad and the ad itself indicated what had injected it, this would feel more trustworthy. But the stakes are too high to have untrustworthy code with access to every page I'm browsing — removed! Thanks to Mukul for the work on this thus far (totally understand that this can be thankless work and monetizing is hard) and thanks to the other reviewers here that have identify this as the offending extension without me having to search through all extensions' source code.
- (2024-05-22) Ashish Chouksey: Sadly removing this extension because of the ad. Even if the ad is harmless, it still feels like a breach because firstly it didn't ask for my permission nor did it inform about its origin (could be a line at the top of the ad saying 'by Mokku') and like others, I had to go through all my extensions to identify its source (I even ran a full scan because I feared it was a malware or something).
- (2024-05-22) Aiden Mellor: Even if the ad is harmless, it still adds unnecessary bloat. Imagine if every plugin did this. Additionally, the ad doesn’t indicate which extension it comes from, making it deceptive and forcing you to search through all your plugins to identify the source.
- (2024-05-21) Giancarlos Castillo: It used to be so good until they started to injecting ads
- (2024-05-20) Drazen Bjelovuk: Injects random ads into web pages.
- (2024-05-20) Abdul Mujib DCT: This extension is injecting ads into webpages.
- (2024-05-20) Ariel Ortmann: It was good, now it injects advertising into sites.
- (2024-04-30) Rishav Agrahari: One of the best API mock extensions I have encountered.
- (2024-03-26) Chirag Pandit: Works
- (2024-03-08) Mefit Hernandez: Awesome extension! Had help me on my day to day work.
- (2024-02-22) Muhammad Abdullah: It is great help. Could you please provide guidance on how to simulate API requests using a syntax pattern similar to sample.com/api/*?
- (2024-01-31) Stuart Myers: Mokku is an excellent lightweight mocking tool for FE development. I would like to leave one bug report - I would open on github but it seems as of Jan 2024 the repo is private(!). When developing a nextjs application, using query parameters and using the nextjs useRouter, navigating gets the following error: Failed to fetch RSC payload for http://localhost:3000/foo?query=bar. Falling back to browser navigation. TypeError: e.url.indexOf is not a function Error: e.url.indexOf is not a function at y (chrome-extension://somethingwrittenhere/js/inject.js:1:6216) // snip This is only an issue when mokku is enabled.
- (2024-01-26) Phil P: Love this extension! I wish there was a way to import/export the created mocks to a json file so my team could be kept in sync with the same mocks. Along with a direct import button to select the json file, an alternative option to import by providing a url to pull in this json file from a remote system.

- (2023-09-01) April Papajohn: This tool is critical for mocking backend service responses during front end development. I especially like the Log feature that lets me capture real responses that I can then mock with one click.
