Why Switch from WireMock?
No Java Runtime Required
Mockd is a single Go binary. No JVM installation, no classpath issues, no garbage collection pauses. Just download and run.
Better Free Tier
WireMock Cloud charges by API calls (1,000/month free). Mockd has no limits — unlimited endpoints and unlimited calls. Use it for load testing without hitting limits.
More Protocols
WireMock supports gRPC and GraphQL via separate extension JARs, and WebSocket only in the unreleased v4 beta. mockd includes all 7 protocols natively in a single binary — no extensions, no extra JARs, no protoc step.
Faster CI/CD
At <10ms startup vs ~5 seconds for WireMock, your test suites run faster. Multiply by hundreds of test runs per day.
mTLS Support
Match requests based on client certificate identity. Essential for microservices with mutual TLS authentication.
Built-in Cloud Tunnel
Share local mocks via a public URL with one command. No need for third-party tools like ngrok. Cloud tunnel supports all 7 protocols on port 443.
