Free mock rest API creator onlineCapture HTTP traffic, create rule, inspect response, webhook development. Free alternative to requestbin and mockbin server to build dummy apis.

Build mock APIs in a few seconds

No downloads, No dependencies.

Create a mock server and start building...
A sub-domain will be created for this endpoint where you can send requests.
collaboration between teams

Break barriers, not your momentum!

Reduce Dependencies and increase developer productivity by deploying mock API contracts. All you need is to create an endpoint, define mocking rules and send mocked responses. Copy the endpoint URL and start sending requests.

It's that simple!

Customer Testimonials

Beeceptor is my goto solution for when I have to quietly observe something in server-side production code, where another logging proxy or remote debugger like Sentry might require a complex installation or extra libraries. Having Beeceptor as a man-in-the-middle between your app and its api is a fantastic tool for working with semi-live data where logging or throwing bogus responses into the datastream is condition you want to test.

Web Developer
For the cost, I am impressed with the features provided. It has been relatively easy to implement within my team, with the ability to create new mocking rules directly via the request logs. Being able to tailor and randomise the responses has been quick and easy to implement. This tool has made it easy to create services that mock these APIs so we can develop and deploy our software with confidence.

Beeceptor Use Cases

Beeceptor solves versatile range of use cases tailored to enhance your development workflow and enabling you to expedite API integrations and software delivery!

Inspect HTTP Traffic
Get a named sub-domain and send an HTTP request. You can inspect the request payload and headers here, pretty-format the payloads and share with your peers.
HTTP Request Details
Build A Mock API
Using Beeceptor, a mock API endpoints is up and ready to be consumed in a few seconds - No Coding Required. Just define API path, matching rule and response payload.
How to setup mock routes
Proxy Mode - Mock or Forward
Wrap an existing API domain with a Beeceptor endpoint to enable proxy mode. Intercept all the traffic going to the original API. Additionally, you can use mocking rules to mock a few requests and forward the rest to target API.
Reverse Proxy & Intercept
Bring Your OAS Spec!
Beeceptor takes your OpenAPI Specification to next level by hosting a mock server with just one click. You can now upload the specification file to an endpoint and start serving requests.
Upload an OAS spec
Dynamic Mocked Response
Customize the response of your mock API by selecting the appropriate request payload and query parameters that fit your specific requirements.
Using Templates Variables
Simulate latencies & timeouts
Simulate higher latencies by introducing delays and timeouts to the mocking rules. Helps you validate rarely reachable code paths.
CORS Support (preflight requests)
Beeceptor, comes with CORS support and all origins are accepted out of the box.

Access-Control-Allow-Origin: *
OPTIONS calls will get '200 OK' always.
Named sub-domains and HTTPs!
Get named endpoints/sub-domains - easy to replace base URL in your code. All endpoints are HTTPs enabled (free or paid).
Request Logging
Search and review all the captured requests and responses. You can filter these by the response-code or request-path to drill down. The requests are available and searchable for 10 days.
Request History

Go beyond traditional API mocks...

  • Beeceptor is a no code solution for building and hosting a mock server.
  • Beeceptor gives you a dashboard to intercept and inspect all HTTP requests in real time.
  • Simulate higher latencies by introducing delays and timeouts. This helps you validate rarely reachable code paths.
  • Use reverse proxy to quickly switch APIs endpoints. E.g. A/B testing by switching API endpoints or versions without any redeployment.
  • Send hyper-customized responses using Handlebar template.
  • When load testing your API, do you really need to pass on the load to downstream APIs? Let Beeceptor mock it for you.
  • Don't block your UI developers when backend APIs are still in development. Just mock it!
  • Create webhook endpoints and capture all the incoming requests. Additionally, setup free local tunnels for development.
  • Share a request and response with peers using unique links.
  • All endpoints support HTTP, HTTPS and HTTP/2.
