Description

๐Ÿš€ Take Control of Your API Workflows with Mokku Stop waiting for backend deployments or struggling with unstable staging environments. Mokku is the ultimate developer tool that integrates directly into your Chrome DevTools to let you mock, modify, and manage API responses seamlessly. Whether you're building a frontend against a non-existent API or testing edge-case error states, Mokku gives you the power of a full mock server right inside your browser. ๐Ÿ› ๏ธ Key Features 1. Powerful API Mocking Complete Control: Specify JSON bodies, HTTP status codes, time delays (latency), and custom headers. GraphQL Native: Full support for mocking GraphQL queries and mutations. Dynamic Responses: Go beyond static files. Write JavaScript functions to return complex, conditional data based on the request. Dynamic URL Matching: Use patterns like /goals/:goalId (powered by path-to-regexp v8.2.0). URL parameters are passed directly to your response functions. Pro Editor: Built-in Monaco Editor (the engine behind VSCode) for a premium coding experience. 2. Flexible Header Modification Modify request headers globally or on a per-URL basis. Perfect for testing auth tokens or custom headers without touching your source code. 3. Effortless Organization & Portability Projects: Group mocks and headers by project to keep your workspace clutter-free. Import/Export: Share mocks with your team or backup your setup by exporting project-based configurations. โš™๏ธ How it Works Mokku adds a dedicated tab to your Chrome DevTools. You can: Click-to-Mock: Pick any existing network call from your logs and turn it into a mock with one click. Start from Scratch: Create custom mocks manually for APIs that donโ€™t exist yet. Safe Injection: Mokku is non-intrusive. It only injects scripts into localhost by default. For all other domains, it remains inactive until you manually enable it from the panel. ๐Ÿ”’ Privacy First Zero Data Collection: Mokku does not collect or request any personal information. Secure Storage: Your mocks are stored safely within your Chrome profile storage. ๐Ÿ”— Links & Resources Whatโ€™s New: https://get.mokku.app/changelog Stop waiting for the backend. Start building with Mokku.

It doesn't work anymore. Tried to override a 200 with a 303, didn't override.

With version 2.1.3, the mock-creation is NOT useful anymore. You are getting forwarded to "mokku.app" website, when click on a network request from within the chrome dev-tools and need to create the mock COMPLETELY manually, without any pre-filled response/request parameters from selected network request... Cannot use this add-on anymore. Was a good friend for years... :(

Disgusting. First, the developer decided to completely hide the source code of the extension, but now he has started inserting advertisements without usersโ€™ permission. Better use the free and fully open source mockiato extension.

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

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 โ€” 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.

Even if the ad is harmless, it still adds unnecessary bloat. Imagine if every plugin did this. Additionally, the ad doesnโ€™t indicate which extension it comes from, making it deceptive and forcing you to search through all your plugins to identify the source.

Awful. Tried to use it and it seems to replace the xhr request object with `undefined` for any non-mocked requests. I would expect all requests to go through instead of requiring every one to be mocked

One of the worst experience ever! It took me days to find that this plugin messed up my network requests and caused them to fail!

I've got this error every single page that I tried "Mokku not available on this url." I'm trying to use on my http://localhost as well.

Does not work at all. No logs, nothing. There seems to be a hack, that overrides XHR which contains errors.

2.1.3 i don't like this upgrade. "add mock" from logs doesn't pass response body, method, url, status

Promising, but doesnt work. After trying half a dozen of these, I thought this one would work since its on dev tools. But no, doesnt manage to intercept and change the live API response.

before the update with redesign it was better and easier to use, moreover after the updates there are a lot of dfferent strange bugs like I can't add two moks for one URL and turn them on and off while testing, previously there was such possibility: I could save any amount of moks for the same url and use them anytime.

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).

I installed this plugin from Chrome web store, I run my application in local with Webpack on localhost:3000. After load the application and move to developer tool and click on the Mokku tab. I got message like "Mokku not available on this url." Could you please help me any one.
