## What it is
Passmark is an open-source TypeScript library that extends Playwright to run end-to-end browser regression tests written in plain English. It uses AI agents to execute natural language steps, caches actions after the first run, self-heals when the UI changes, and verifies assertions with multiple vision models for consensus.

## Use cases
- write e2e browser tests in plain English
- catch UI regressions before users do
- self-heal flaky Playwright tests when selectors drift
- run AI-driven browser automation with caching for speed
- verify test assertions with multiple AI vision models
- add regression testing to a project without maintaining brittle selectors

## When to choose
- you want natural-language end-to-end tests on top of Playwright
- your existing browser suite is brittle and flakes on selector drift
- you want AI test authoring but pure-AI runners are too slow
- you need multi-model consensus for assertion verification

## When to avoid
- you need a fully deterministic, non-AI test suite with zero LLM API costs
- you cannot share code or API keys with Anthropic/Google or an AI gateway
- you need a permissively licensed dependency (license is FSL-1.1-ALv2, not OSI-approved)
- your tests must run fully offline
