Introduction

Monocart Reporter is a Playwright test reporter for Node.js. Its README lists a tree-grid style report, high-performance processing of large result sets, a design for customisation and extensibility, interactive grouping with ultra-fast filtering, a timeline workers graph, CPU and memory monitoring, and JSON data export.

Beyond basic reporting, it supports custom columns and metadata, comments and annotations, attachments, trend charts across runs, and code coverage collection and reporting through the related monocart-coverage-reports project. The repository now ships an AI agent skill that helps coding agents configure Playwright reports.

Release 2.14.1 shipped in October 2026.

In the quality loop it supports release reviews of Playwright runs.

The source code is at cenfun/monocart-reporter on GitHub under the MIT licence, with about 328 stars; the most recent commit was on 28 October 2026.
