## What it is
WireMock is a popular open-source tool for mocking HTTP-based APIs, runnable as an embedded Java library, standalone server, or container. It offers rich request matching, Handlebars response templating, record/playback, fault injection, and request verification.

## Use cases
- mock a third-party REST API in my integration tests
- simulate an API that doesn't exist yet during development
- stub HTTP responses with matching on URL, headers, and body
- record real API traffic and replay it in tests
- inject latency and network faults to test resilience
- verify my app sent the expected HTTP requests
- run a mock server in Docker for CI pipelines

## When to choose
- you need stable, isolated test environments free of flaky third-party dependencies
- you want flexible stubbing via code, JSON files, a REST admin API, or traffic recording
- you need fault/latency simulation and request verification in automated tests
- you work on the JVM (Java, Kotlin, Groovy) or want the standalone server/container

## When to avoid
- you only need simple in-process function mocking rather than HTTP-level simulation
- you need collaborative, stateful multi-team mock management with SSO and audit logs (consider WireMock Cloud)
- your stack is non-JVM and a native mocking tool for that language would fit better
