Overview

What is Webwright?

Webwright is an open-source browser agent framework from Microsoft that targets SWE-style, long-horizon web tasks. It is useful for teams comparing browser-use style agents, Playwright-based automation, and agent frameworks that need repeatable web task execution.

Long-horizon browser focus

Webwright is positioned around multi-step web tasks rather than isolated browser commands.

Long-running workflows need state tracking, retries, and task decomposition that basic automation scripts often lack.

Research-friendly surface

The project is useful for comparing browser agent performance across repeatable tasks.

Teams can use it as a benchmarkable alternative to ad hoc browser agent demos.

Microsoft backing

The repository is maintained under the Microsoft GitHub organization.

A major maintainer increases the odds of documentation, issue visibility, and ecosystem attention.
Use cases
