Introduction

Cappa is a Playwright-powered screenshot tool that helps teams spot visual regressions early. It wraps browser automation from Playwright in a workflow tailored for visual reviews so that you can capture, compare, and approve screenshots with confidence.

Why Cappa?

• Automated coverage. Capture screenshots across routes, viewports, and themes using the same Playwright foundation your team already trusts.
• Deliberate review flow. Run cappa capture, cappa review, and cappa approve to create a repeatable approval process that fits continuous delivery pipelines.
• Extensible by design. Cappa ships with a plugin system so you can connect Storybook or other custom data sources without forking the core tool.
• Local Cappa captures screenshots locally and relies on your vcs to track changes.

Core features

Cappa is composed of a lightweight CLI and a composable configuration layer provided by @cappa/core. Together they make it easy to:

1. Define screenshot targets in a cappa.config.ts file.
2. Capture images locally or in CI using cappa capture.
3. Review diffs in an interactive UI with cappa review.
4. Approve changes and sync baselines with cappa approve.
