All-in-one CLI for mocking and testing APIs. AI-first, Git-native playbooks in YAML. Run from CLI or VS Code, and automate with confidence.
Hey everyone,
I've been working on a project called Quadrastack and wanted to share it here.
The problem I was trying to solve:
If you've ever worked on a team with separate dev and QA roles, you probably know this workflow: you test your APIs in Postman/Bruno, export the collection, email it to QA, they re-run everything, find a bug, email you back... rinse and repeat.
Or maybe you went the "proper" route and wrote integration tests in Jest/Pytest. But then your QA team can't read or modify those tests, so they end up doing manual testing on the side anyway. Now you've got three versions of "the tests" that slowly drift apart.
What I built:
Quadrastack is a CLI tool where you write API tests in YAML. The idea is simple—YAML is readable enough that your QA engineer can open a test file and actually understand what it does. Same file runs in your CI pipeline. Same file gets reviewed in PRs with clean, readable diffs.
Core features:
YAML playbooks - Define requests, assertions, and test scenarios in plain YAML
Built-in mock server - Spin up mock APIs without external dependencies
Load testing - Stress test your endpoints with configurable concurrency
VS Code extension - Run tests directly from your editor without switching tools
Works offline - No account needed, no cloud sync, your data stays local
AI-friendly schemas - JSON schemas included so AI tools (Copilot, Claude, etc.) can auto-generate test playbooks from your API specs or descriptions
