Why Proxymock?

🤖

Model Context Protocol (MCP) Enabled

Give your AI model instant access to a realistic test environment. No cloud costs required.

⚙️

Auto-generates Tests and Mocks

Automatically create comprehensive test suites and mock responses from your production traffic recordings.

☸️

Kubernetes, ECS and Desktop API Recorders

Record in one environment and replay in another — no expensive cloud replicas required.

🚀

CI Pipeline-Friendly

Integrate seamlessly into your CI/CD pipelines for automated testing and validation at every deployment.

🔒

PII Redaction

Automatically detect and redact personally identifiable information to ensure data privacy and compliance.

📊

Tests Regression, Load and Configuration

Comprehensive testing capabilities including regression testing, load testing, and configuration validation.

Recording

Gather real traffic from your application using HTTP/SOCKS proxy, reverse proxy, desktop or even capture. Give your AI coding tool real world data to work with.

HTTP & gRPC

Capture REST and gRPC calls with headers and bodies preserved for replay.

Cloud Services

S3, Pub/Sub and other managed services are recorded for accurate mocks.

Databases

Postgres, MySQL and Redis interactions can be captured and analyzed.

Quickstart

brew install speedscale/tap/proxymock
export http_proxy=http://localhost:4140
export https_proxy=http://localhost:4140
proxymock record -- go run main.go

See the installation docs for more details and language specific instructions.

Testing & Mocking

Turn recordings into fast, deterministic tests and use production‑like mocks to develop without external dependencies.

Run tests

proxymock replay --test-against localhost:3000 --for 1m --vus 10

Regression, contract and load from real traffic, quickly fire it up from your terminal.

Start mock server

proxymock mock -- go run main.go

Realistic latency and errors; add transforms for chaos and data shaping.

CI Pipeline

Add Proxymock to your pipeline to catch issues before deploy. See full examples in our CI/CD docs.

Start mock server

proxymock mock \
  --verbose \
  --in $PROXYMOCK_IN_DIR/ \
  --log-to proxymock_mock.log &

Replay and test

proxymock replay \
  --in "$PROXYMOCK_DIR" \
  --test-against localhost:$APP_PORT \
  --log-to $REPLAY_LOG_FILE \
  --fail-if "latency.max > 1500" \
