# BaseWatch — CSS & Browser Feature Support Tracker

> BaseWatch helps web developers watch CSS properties, JavaScript APIs, and HTML platform features and get notified when support reaches a target threshold.

## What is BaseWatch?

BaseWatch is a free developer tool focused on one job: **notify you when a web feature is ready to use.**

Instead of manually checking compatibility tables over and over, you watch a feature once and BaseWatch alerts you when it reaches your chosen support threshold.

It combines data from [Can I Use](https://caniuse.com) and [Web Platform Baseline](https://web.dev/baseline) to show:
- Real-time global browser support percentages
- Support split between full support and partial support
- Per-browser compatibility snapshots
- Baseline status: Widely Available, Newly Available, or Limited
- Projected 95% support windows for non-Baseline features

Available watch channels:
- Email alerts with confirmation and unsubscribe links
