The app was built with create-react-app.

Running the application

Fork and/or clone the jaeger-ui repo and change directory into it.

git clone
cd jaeger-ui

Use the recommended Node versions: (defined in .nvmrc file):

nvm use

Install dependencies via yarn:

yarn install --frozen-lockfile

Make sure you have the Jaeger Query service running on http://localhost:16686. For example, you can run Jaeger all-in-one Docker image as described in the documentation.

If you don't have it running locally, then tunnel to the correct host and port:


If you are using the UI Base Path feature, you need to append the base path into jaeger-ui/jaeger-ui/vite.config.js in proxyConfig object. For example, if the base path is "/jaeger", then the target should be "http://localhost:16686/jaeger" and your proxyConfig object would be:

const proxyConfig = {
  target: 'http://localhost:16686/jaeger',
  secure: false,
  changeOrigin: true,
  ws: true,
  xfwd: true,

Start the development server with hot loading:

yarn start

The above command will run a web server on http://localhost:5173 that will serve the UI assets, with hot reloading support, and it will proxy all API requests to http://localhost:16686 where Jaeger query should be running.


Command Description
yarn start Starts development server with hot reloading and api proxy.
yarn test Run all the tests
yarn lint Lint the project (eslint, prettier, typescript)
yarn fmt Apply Prettier source code formatting
yarn build Runs production build. Outputs files to packages/jaeger-ui/build.

Running on Windows OS

While we don't natively support Windows OS for running the Jaeger UI Dev Environment, you can use Windows Subsystem for Linux (WSL) to run it.

Here are some steps to follow:

  1. Install WSL:
  2. Install Node.JS:
  3. Install Yarn:
  4. Connect WSL Environment with VSCode:
  5. Use the WSL Terminal inside VSCode and follow the Jaeger UI installation steps

UI Configuration

See the configuration guide for details on configuring Google Analytics tracking, menu customizations, and other aspects of UI behavior.
