Grunt plugin that runs phantomas to measure and visualize frontend performance metrics with historical tracking.
grunt-phantomas is a Grunt plugin that automates frontend performance testing by running the phantomas tool. It collects detailed metrics about website performance—such as load times, request counts, and asset sizes—and generates visual reports with historical tracking. It solves the problem of manually monitoring performance regressions by integrating performance checks into automated build processes.
Frontend developers and DevOps engineers who use Grunt as their build tool and need to integrate performance monitoring into their CI/CD pipelines. It's particularly useful for teams that want to enforce performance budgets and track metrics over time.
Developers choose grunt-phantomas because it seamlessly integrates performance testing into existing Grunt workflows, provides rich visualizations out of the box, and supports performance budgeting with assertion-based warnings. Its ability to track history across deployments makes it a robust tool for catching regressions early.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Executes phantomas multiple times (default 5 runs) to collect reliable performance data, reducing variance in metrics like requests and timings.
Generates an interactive HTML dashboard with graphs that track performance over time, making it easy to visualize regressions across deployments.
Supports configurable assertions to warn when metric medians exceed thresholds, enabling teams to enforce and monitor performance budgets directly in the UI.
Designed for CI systems like Travis CI with caching guidance for the indexPath, allowing history tracking across builds without manual intervention.
Tied exclusively to Grunt builds, making it incompatible with modern toolchains like Webpack or Gulp without significant workflow changes.
The 'Maintainers Wanted' badge and last update indicators suggest the project may not be actively maintained, risking outdated dependencies or bugs.
Requires extensive Gruntfile setup for assertions, grouping, and phantomas options, which can be time-consuming and error-prone for new users.
Does not support phantomas formatters, as admitted in the README, restricting output formats and integration with other reporting tools.
