base on A Chrome DevTools Protocol driver for web automation and scraping. # Overview [](https://pkg.go.dev/github.com/go-rod/rod) [][discord room] ## [Documentation](https://go-rod.github.io/) | [API reference](https://pkg.go.dev/github.com/go-rod/rod?tab=doc) | [FAQ](https://go-rod.github.io/#/faq/README) Rod is a high-level driver directly based on [DevTools Protocol](https://chromedevtools.github.io/devtools-protocol). It's designed for web automation and scraping for both high-level and low-level use, senior developers can use the low-level packages and functions to easily customize or build up their own version of Rod, the high-level functions are just examples to build a default version of Rod. [中文 API 文档](https://pkg.go.dev/github.com/go-rod/go-rod-chinese) ## Features - Chained context design, intuitive to timeout or cancel the long-running task - Auto-wait elements to be ready - Debugging friendly, auto input tracing, remote monitoring headless browser - Thread-safe for all operations - Automatically find or download [browser](lib/launcher) - High-level helpers like WaitStable, WaitRequestIdle, HijackRequests, WaitDownload, etc - Two-step WaitEvent design, never miss an event ([how it works](https://github.com/ysmood/goob)) - Correctly handles nested iframes or shadow DOMs - No zombie browser process after the crash ([how it works](https://github.com/ysmood/leakless)) - [CI](https://github.com/go-rod/rod/actions) enforced 100% test coverage ## Examples Please check the [examples_test.go](examples_test.go) file first, then check the [examples](lib/examples) folder. For more detailed examples, please search the unit tests. Such as the usage of method `HandleAuth`, you can search all the `*_test.go` files that contain `HandleAuth`, for example, use GitHub online [search in repository](https://github.com/go-rod/rod/search?q=HandleAuth&unscoped_q=HandleAuth). You can also search the GitHub [issues](https://github.com/go-rod/rod/issues) or [discussions](https://github.com/go-rod/rod/discussions), a lot of usage examples are recorded there. [Here](lib/examples/compare-chromedp) is a comparison of the examples between rod and Chromedp.
