Prowl CLI
Deterministic end-to-end testing in readable YAML, run with Playwright precision.
- Write flows as YAML hunts — no brittle test code
- Visual regression detection + rich debugging artifacts
- CLI-first, agent-ready, with an MCP server
The Prowl Suite
A testing suite made for agents, controlled by humans.
Prowl is a suite of development tools from Genkei Labs — end-to-end testing, AI code review, community templates, and infrastructure validation. Each is CLI-first, agent-ready, and free to adopt. Pick one, or run them all.
The tools
Four tools, one testing philosophy
Each product stands on its own and shares the same DNA — CLI-first, agent-ready, and yours to own. Start anywhere.
Prowl Code Review
BYOK AI code review for pull requests — quality-first, with no rate limits.
- Multi-pass specialists + judge, cross-file context
- Linter/SAST grounding + false-positive verification
- Your key, your provider — cents per review
Prowl Hub
A growing library of community hunt templates — copy real-world flows and adapt them.
- Browse battle-tested YAML flows by category
- Copy, adapt, and contribute back
- Wired into the CLI via the Hub API
Prowl Infra
Infrastructure test playbooks — validate cloud and Terraform environments before you ship.
- Catalog of reusable infra validation playbooks
- Catch misconfigurations pre-deploy
- Same CLI-first, agent-ready philosophy
Why Prowl
What makes it a suite, not a toolbox
Made for agents, controlled by humans
Every tool is safe to point at agent-generated work — deterministic, bounded, and reviewable — without runaway cost or surprises.
Own your keys, no lock-in
BYOK where inference is involved (Code Review), open formats everywhere else. Your data goes to your providers, not ours.
CLI-first, zero infrastructure
Each tool runs from the terminal or CI with nothing to host. Start in seconds; scale without a control plane.
Open source, from Genkei Labs
Apache-2.0, transparent, and built in the open as a cohesive QA suite — not a pile of disconnected utilities.
Documentation
Docs for every tool
Each product has its own documentation site. Jump straight to the one you need — they share the same look and cross-link to each other.
Start catching regressions today
Deterministic E2E coverage from install to first test in minutes.
YAML hunts, Playwright reliability, and rich artifacts — add flow coverage to your workflow without the complexity.
