What is it?

DoKit is a development efficiency platform from Didi that embeds a floating debugging panel into apps during development. It gathers commonly reimplemented internal tools such as frame-rate and CPU/memory monitors, environment switching, log viewing, a sandbox file browser and MockGPS location spoofing into one entry point, so teams do not need to build these separately in each app.

The project covers several ecosystems: DoKit for Android, DoKit for iOS, DoKit for WeChat mini-programs, DoKit for Flutter, and support for Chameleon/Weex pages. The companion dokit.cn platform adds interface mocking through network interception, a health check that combines several performance tools, a file sync helper and multi-device control.

The toolkit is intended only for Debug builds. The maintainers state that Release use has not been validated and advise against it, so integration should follow the official guide.

Key features

  • 01Floating panel with frame rate, CPU, memory and traffic monitoring charts
  • 02App network traffic interception with list, filter and detail views
  • 03Interface mocking via network interception without code changes
  • 04MockGPS location simulation and weak-network simulation on Android
  • 05Sandbox file browsing, Crash stack viewing and local NSLog or Lumberjack output on iOS
  • 06Visual tools such as color picker, component inspector and alignment ruler

Use cases

  • Debugging layout, color and alignment issues during UI development
  • Profiling startup time, slow frames, large images and memory leaks in a test build
  • Simulating locations or weak networks when testing location-based or network-sensitive features
  • Sharing mock data and file access with teammates through the dokit.cn platform

Quick start

  1. 1

    Open the DoKit official site and go to the usage center for your platform

  2. 2

    Integrate the SDK for your platform by following the official integration docs

Things to know

  • All features are designed only for Debug builds; Release builds are not verified and are not recommended.
  • Some tools are platform-specific, such as iOS-only or Android-only features.
  • The SDK sends usage, health-check and mock-related data to dokit.cn servers.
