A set of libraries, tools, and visualizers for tracing and investigating performance in complex web applications.
Web Tracing Framework is a set of libraries, tools, and visualizers for instrumenting and tracing complex web applications to uncover performance problems. It helps developers track regressions and optimize for smooth 60fps experiences by providing detailed insights into application execution.
Web developers and performance engineers working on complex JavaScript applications who need deep visibility into runtime behavior and performance bottlenecks.
It offers a comprehensive, open-source solution for performance tracing with visualizers and a Chrome extension, enabling detailed analysis without heavy proprietary tooling.
Web Tracing Framework libraries and extensions.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Instruments code to capture detailed timing data, enabling discovery of bottlenecks and optimization for 60fps, as highlighted in the key features and philosophy.
Provides visualizers to explore trace data, making it easier to identify and analyze performance issues without relying solely on console logs.
Helps monitor performance changes over time to catch degradations, which is crucial for maintaining app quality across versions.
Licensed under BSD, allowing for forking and customization, as mentioned in the license section, with minimal legal restrictions.
Requires cloning the repository, running setup scripts, and manually loading a Chrome extension, as per the quickstart guide, which can be time-consuming.
The README describes it as a work in progress with known issues, and the Travis CI build status suggests it may not be actively maintained for modern web standards.
Primarily relies on a Chrome extension for injection, limiting usability in other browsers or for teams focused on cross-browser development.
