Beeceptor - mock api serverBeeceptor Features & Use Cases

Discover how Beeceptor can streamline your development workflow, speed up API integrations and software delivery. Explore the range of use cases Beeceptor can solve for you below!

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 Mock APIs

With Beeceptor, a mock API server is up and running in a few seconds - No Coding Required. Just define API path, matching rule and response payload.

CRUD APIs With Storage

Define an entity path and let Beeceptor automatically set up six essential JSON REST APIs for your CRUD operations. This JSONPlaceholder alternative has a flexible schema, storage and super easy setup.
Create CRUD APIs

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 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

HTTP Request Monitoring

Monitor HTTP requests and responses in real time. Beeceptor acts as an HTTP logger to help you spot failed API calls and errors in payloads, with logs kept searchable for up to 10 days.
Request History

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.

Local Services On The Internet

Beeceptor's local tunnel gives a secure public HTTP endpoint, directing incoming traffic to a designated localhost port. Use this for webhook testing, conduct demos directly from localhost, and share applications over the internet.
Local Tunnel

Simulate Rate Limits

Configure your endpoint to mimic rate limits, setting maximum requests per second, minute, or hour. This is essential when developing queue consumers or integrating 3rd party APIs requiring retry mechanisms.
Rate Limits

Off-the-shelf Dummy JSON Server

Delve into a readily available JSON API server designed specifically for retrieving dummy data for entities such as Blog Posts, CommentsCompanies, Notifications, and more.
Discover how Beeceptor empowers your development workflow with API Mock Server, Local Tunnel and HTTP Proxy toolset.

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.

Trusted by thousands of developers and QA engineers across the globe eliminating API bottlenecks everyday!
Fastest Mock REST API I have ever done. After getting sick of installing and configuring local tools or struggling with cloud servers to get some dummy APIs up so I can see what my app sends and manipulate the response... Beeceptor made that 2min task!

Ease of use is the main thing about it. It's also quite flexible too. I've been using it to mock integrators that are being developed in parallel to my app and having Beeceptor as a fake integrator has helped me to catch bugs early on.
