Bullet Train

Bullet Train is an open source service for managing feature flags and remote configuration. It lets teams change how an app looks, behaves and is set up without releasing a new build.

It works across web, mobile and server-side applications and forms part of a continuous integration approach.

What Bullet Train offers

• Feature flags — switch features on or off for chosen users.
• Remote configuration — adjust settings in a running app.
• Testing in production — try changes with real traffic before wider release.
• Faster iteration — ship, fix and refine without waiting on app store builds.

Who it works with

Startups and larger companies building web, mobile or server software.
