Monorail Issue Tracker

Monorail is the Issue Tracker used by the Chromium project and other related projects. It is hosted at

If you wish to file a bug against Monorail itself, please do so in our self-hosting tracker. We also discuss development of Monorail at

Getting started with Monorail development

For Googlers: Monorail's codebase is open source and can be installed locally on your workstation of choice.

For local development on Linux, see Linux development instructions For local development on MacOS and Debian, see MacOs development instructions

Instructions for deploying Monorail to an existing instance or setting up a new instance are here.

Python backend testing

make pytest

To run a single test:

vpython3 services/test/

JavaScript frontend testing

make jstest

If you want to skip the coverage for karma, run:

make karma_debug

To run only one test or a subset of tests, you can add .only to the test function you want to isolate:

// Run one test.
it.only(() => {

// Run a subset of tests.
describe.only(() => {

Just remember to remove them before you upload your CL.
