Beeceptor

Beeceptor is a developer-focused API simulation platform for creating mocks, virtualizing services, testing contracts, and simulating failures. It supports HTTP, HTTPS, HTTP/2, mTLS, REST/OpenAPI, SOAP, GraphQL, and gRPC. Users can make no-code mocks with request-matching rules and customize response codes, headers, and bodies. An uploaded OpenAPI specification can produce a populated mock server with AI-generated data. Beeceptor can proxy and record live backend traffic, then switch to mock behavior if a backend is unavailable. Teams can also introduce latency, timeouts, and errors to check client resilience. Its CLI exposes a local service through a public HTTPS URL on Windows, macOS, and Linux. Management APIs support programmatic configuration, and MCP connectivity supports AI agents including Claude and Cursor. The platform offers a free plan and a 10-day trial; paid plans start at $10 a month. Free endpoints are public by default, accept payloads up to 1 MB, and unclaimed endpoints are removed after 30 days.

Beeceptor brings API mocking, traffic recording, and controlled failure simulation into one developer-focused platform. Check the free endpoint and retention limits against your testing needs.

It suits developers, testers, and QA professionals working with API mocks for development, testing, integrations, CI pipelines, or customer demos.

Overview

Beeceptor is a developer-focused platform for API simulation, service virtualization, contract testing, and controlled failure scenarios. It is best suited to developers, testers, and QA teams building integrations, CI pipelines, or customer demos. Its mix of mock creation, traffic recording, and resilience testing covers more than simple response fixtures, while the free tier’s public endpoints and modest quotas limit its fit for sensitive or sustained work.

Key features

No-code rules match requests and let users set response status codes, headers, and bodies. This makes it practical to create controlled API behavior without building a separate mock service; the Free plan’s three-rule limit, however, is better for simple cases than complex test suites. Beeceptor supports HTTP, HTTPS, HTTP/2, mTLS, REST/OpenAPI, SOAP, GraphQL, and gRPC, so it can serve teams working across different protocols and API styles.

An uploaded OpenAPI specification can generate a populated mock server with AI-generated data, a useful shortcut when a team needs a working stand-in from an existing contract. Beeceptor can also proxy requests to live backends, record traffic, and switch to mock behavior when a backend is unavailable. Latency, timeouts, and errors can be simulated to test client resilience, making the platform relevant to failure-path testing as well as successful responses.

The CLI exposes a local service through a public HTTPS URL and runs on Windows, macOS, and Linux. Persistent tunnels are included on paid plans; the Free plan has an ephemeral tunnel, which is less suitable when a development endpoint needs to stay available. Management APIs support programmatic mock-server operation, while MCP connectivity works with AI agents including Claude and Cursor. API Connections store OAuth credentials and generate tokens for outbound requests through callout or proxy rules.

Beeceptor says it is SOC 2 Type II audited, adheres to ISO 27001, and is GDPR compliant, with data encrypted in transit and at rest. Request payloads are retained for 15 days before permanent purging, while metadata-only application logs are retained for 90 days. Those retention windows matter when teams need traffic records for longer investigations.

Pricing

Beeceptor has a Free plan and a 10-day trial, with paid plans starting at $10 a month. The Free plan allows 50 requests/day per endpoint, three mock rules, public endpoints, and 10 small CRUD objects. It has an ephemeral local tunnel; unclaimed endpoints are cleaned up after 30 days, while claimed endpoints are retained for 90 days. Public endpoints make this tier a poor choice for private workflows, and its daily request cap can constrain shared or repeated testing.

Individual costs $10 a month and includes 15,000 requests/month per endpoint, up to 50 mock rules, private endpoints, 100 CRUD objects, a persistent local tunnel, and chat and email support. It is the practical step up for an individual or small project that needs private mocks and predictable monthly capacity.

Team costs $25 a month, raising the allowance to 100,000 requests/month per endpoint and the ceiling to 250 mock rules and 500 CRUD objects. It adds live and historical traffic inspection while retaining private endpoints, persistent tunnels, and chat and email support. The higher cap and inspection tools suit teams that need to review activity across integration work rather than rely on a small individual allowance.

Scale costs $99 a month and includes 1M+ requests/month per endpoint, up to 500 mock rules, 5,000 CRUD objects, private endpoints, live and historical traffic inspection, a persistent tunnel, and chat and priority email support. It is aimed at heavier endpoint traffic and larger mock collections; the higher monthly price is difficult to justify for low-volume projects. Paid Individual and Team plans include chat and email support, while Scale upgrades email to priority.

Platforms

Beeceptor is available as a web service and supports Linux, macOS, and Windows, including through its CLI. Its deployment model is both hosted and self-hosted, giving teams a choice beyond the browser-based workflow.

Who it's for

Choose Beeceptor when an API team wants one platform for mocks, proxying and recording live traffic, contract-oriented workflows, and deliberate failure simulation. It is particularly well matched to development, integration tests, CI pipelines, and customer demos where dependencies may be unavailable or need controlled behavior. Look elsewhere if a free solution must keep endpoints private, if a 50-request daily endpoint cap is too low, or if payload retention needs to extend beyond 15 days.

Pros and cons

• Broad protocol coverage: HTTP-family protocols, REST/OpenAPI, SOAP, GraphQL, and gRPC accommodate varied integration environments.
• Useful beyond static mocks: Proxy fallback, traffic recording, and simulated latency, timeouts, and errors support integration and resilience testing.
• Practical paid tiers: Private endpoints and persistent tunnels begin with Individual, while Team and Scale add progressively larger request and CRUD-object limits and traffic inspection.
• Free tier is constrained: Public endpoints, three rules, 50 requests/day per endpoint, and endpoint cleanup make it a limited option for ongoing or confidential work.
• Short payload retention: Request bodies are purged after 15 days, which may not suit longer investigations or audit needs.

Alternatives

Tricentis Testim is worth considering when mobile and web testing runs are the priority: its Free plan allows up to 1,000 runs/month, while paid pricing is customized to testing needs. Parasoft SOAtest is another paid option with tailored pricing based on business needs and a free trial.

LocalStack may fit a team focused on emulating AWS services: its free Hobby plan includes 30+ emulated services and one personal sandbox, with non-commercial use. Microcks is a free, 100% open-source, community-driven CNCF Incubating project. Wilma is a free GPLv3.0-licensed option.

Amazon RDS is an alternative for managed relational database needs rather than API mocking; its Free Tier terms include credits valid for up to 12 months, with legacy accounts potentially receiving 750 hours per month for up to 12 months. For local storage emulation, Azurite is an open-source Azure Storage emulator, while DynamoDB Local is a free download for local development and testing, not production use.

Verdict

Beeceptor is a strong choice for API developers and QA teams that need flexible mocks alongside live traffic recording and controlled failure testing. Its broad protocol support and paid plans’ private endpoints and persistent tunnels are the main reasons to choose it. Look elsewhere if free use must be private, endpoint traffic exceeds the Free plan’s cap, or request payloads need to remain available beyond 15 days.
