Beeceptor is a free alternative to WireMock and MockLab for building mock APIs.

Best Alternative To WireMock

Beeceptor is a no-code solution for building and deploying mock servers instantly!
A mock server that never sleeps!

WireMock Cloud is a managed API mocking platform that builds upon WireMock, an open-source API mocking framework. Formerly known as Mocklab.io, it underwent rebranding as WireMock Cloud in December 2022. WireMock Cloud comes with free and enterprise plans.

Beeceptor and WireMock Cloud are both powerful tools for creating and deploying mock servers and virtualizing services. While they share several similar features such as cloud/hosted services, endpoint naming, forward proxy for call recording, simulating failures, HTTP delays, request history, and Handlebars templates, Beeceptor offers distinct advantages over WireMock Cloud. Below is a comparison table that highlights the major benefits of using Beeceptor over WireMock Cloud.

Beeceptor
WireMock Cloud
Category
Beeceptor gives you managed mock servers.

It goes beyond API Mocking and supports all kinds of HTTP debugging. It gives you a server endpoint to accept HTTP requests, inspect payloads, route requests to localhost, or forward them through a proxy.
WireMock Cloud is a managed version of open-source WireMock.

It uses the same open-source WireMock package and hosts the exact same features. It is developed by the same team. (The open-source WireMock.org is written in Java.)
Pricing
Free for 1,500 requests/month (50 requests/day)
(Beeceptor offers almost all features in the Free plan.)
Individual: $10 for 15,000 requests/month
Team: $25 for 100,000 requests/month

Unit: Pricing per mock server (subdomain). Unlimited users and sharing.

WireMock Cloud is free for 1,000 requests/month
(WireMock's Free plan is basic and not designed for complex needs.)
Team: $47 for 10,000 requests/month
Expensive Enterprise Plans
OAS/Swagger Support
Beeceptor lets you upload OpenAPI specifications and instantly create mock servers powered by AI with contextual test data. You can upload or import OpenAPI specs any number of times.
WireMock Cloud supports OpenAPI specifications on free and paid plans, but does not provide automated test data generation.
Management of Mocking Rules
Easy to manage mocking rules, priorities, and execution.

  • Mocking rules are executed in a top-to-bottom order, where the first matching rule takes precedence.
  • Easily modify the priority of rules by dragging them to the desired position.
  • Temporarily disable specific rules to control execution flow.
  • Audit logs: The Enterprise plan comes with audit logs, which track changes made by the team to an endpoint.
In WireMock Cloud, mocking routes are referred to as stubs, serving as the primary matching criteria for incoming requests. The execution of mocking rules depends on the specified priority index for each stub.

  • You need to manage the priority of each stub (request path or route) from a dropdown of [1-10] values. The listing order of stubs is updated on save.
  • You cannot disable a stub temporarily. Instead, you need to delete it.
  • Audit logs: The ability to track changes made by the team to an API is not available with WireMock Cloud.
Real time
Beeceptor gives you an engaging real-time experience. You can view incoming requests and responses in real time as they happen. It uses fanout architecture to push notifications to all the consumers who are currently online.
WireMock Cloud isn't built as a real-time platform. For example, you need to go to request logs and pull updates by clicking the 'Refresh' button.
Forward Proxy
Beeceptor lets you proxy traffic to your original APIs, both at the global level and within individual mock rules.
The global proxy acts as a fallback. If no matching mock rule is found, the request automatically routes to the real API. This setup makes it easy to patch new mocks on top of existing API endpoints, giving you a partial mock experience.
WireMock Cloud lets you proxy traffic to the original APIs. The proxy is available at the stub level (route or mock rule).
If you want a fallback, you need to create a proxy stub with the lowest priority value and a generic match.
Dynamic Mock Responses
Beeceptor supports Handlebars syntax for accessing a request's body, headers, query parameters, etc.

Beeceptor supports the following.

  • Supports parameter extraction from JSON, XML, and form URL-encoded request payloads.
  • Use syntax compatible with FakerJS to generate realistic dummy data like people's names, products, cities, dates, numbers, and more.
  • Includes advanced features like XML payload extraction and conditional logic (if...else, each)
  • Full support for string, date, math, comparison, array, and encoding operators to craft dynamic, real-world API responses.

WireMock Cloud supports Handlebars syntax for accessing a request's body, headers, query parameters, etc.

WireMock Cloud supports the following.

  • Supports parameter extraction from JSON, XML, and JWT payloads.
  • Supports additional helpers like Base64 encode/decode, string manipulation, etc.
  • Supports conditional logic helpers.

Datasets
Beeceptor lets you import CSV, JSON, or NDJSON test data once and reuse it across endpoints. You can query data independently or chain lookups to keep related data consistent. This feature lets you manage test data separately from the virtual service configuration.

Read the docs
WireMock Cloud supports CSV file imports and documents support for external database connections in private beta. In a stub, you can use one attached data source and query.

Read the docs
Configuration Snapshots
One-click configuration backup and restore. Save mock rules, responses, runtime settings, and all virtual behaviors together. You can use Pull Snapshot to promote a tested configuration from development to QA or another eligible endpoint.

Read the docs
Direct or one-click configuration promotion is not available with WireMock Cloud. It supports version history and restore. Cross-environment promotion is available via the CLI.
Load-Based Latency (RPS)
Beeceptor lets you simulate response latency dynamically based on the endpoint's current requests per second (RPS). You can simulate a third-party API slowing down as traffic increases in production and test how your application handles throughput and retries under load.

Read the docs
WireMock Cloud does not support a dynamic latency profile that automatically adjusts response delays based on the virtual server's current RPS.
Stateful mocks
  • Beeceptor maintains global state across all endpoints by default, and lets you scope data per user, session, or rule using context identifiers in the key names.
  • A dedicated state management UI to easily search, debug, and edit state values in real time.
  • Has REST APIs to set, reset, and bulk update state variables programmatically (ideal for CI pipelines).
  • Rich Data Structures: Supports lists, objects, numbers, and strings, along with atomic numeric counters for stepwise or incremental state updates.
  • WireMock isolates states by context, where each request context maintains its own instance of state values. The default context is the current rule/route.
  • It manages state inside individual stubs. There is no global view or UI to inspect or modify values. You need to update values via stub configuration.
  • There is no API to preset, update, or manage state data externally.
  • WireMock stores values as literal strings. It lacks true lists, sets, or atomic counters.
CRUD Mock APIs
Beeceptor supports CRUD routes as pure REST APIs, designed with best practices. Simply define a base path like /api/users, and you can push JSON objects, retrieve them, and use stateful operations with built-in sorting, filtering, and pagination.

Read the docs
WireMock Cloud requires a manual and complex setup to simulate CRUD behavior. It lacks native support for filtering, sorting, or pagination, making data simulation harder to maintain.
Binary Response (File Serving)
Beeceptor supports the uploading of binary files like GZIP, PDF, MP4, etc., to mock binary API responses, facilitating effective simulation and testing of how applications process different file formats.
WireMock Cloud allows for binary content via Base64 encoding, but it requires manual conversion of the file to Base64. This encoded data must then be pasted into the mock configuration, a process that may not be intuitive.
Request Log/History
The call logs (referred to as Request History) are available for 15 days with the Team plan and above.

  • You can search and filter history using facets. E.g. request path, HTTP status code, text inside the request or response body, etc.
  • You can download all the requests as a HAR file to visualize locally.
WireMock Cloud call logs (referred to as Request Log) are available only for the most recent 200 requests on all plans.

  • Search and filtering are basic and only work on the request path.
  • You cannot download the request logs. You can review only the most recent 200 requests.
Local Tunnel
Beeceptor supports local tunneling. As a developer, you can route all the incoming requests to an API service running locally on your development machine.
Read more about Local Tunnel setup.
WireMock Cloud doesn't support local tunnels.
Support for HTTP/2
Beeceptor supports HTTP/2.
WireMock Cloud doesn't support HTTP/2.
White Label
Domain white labeling allows you to use your own domain while concealing Beeceptor's subdomain/endpoint.
White Labeling is not available with WireMock. You cannot bring your own domains with WireMock Cloud.
Support
Beeceptor provides email support with paid plans.
(Priority email support with the Enterprise plan.)
WireMock Cloud provides community support with paid plans.
