Context

Flagit is a feature-flag management SaaS inspired by Flagsmith. It lets a team turn features on for some users and environments without redeploying.

What I built

  • Environment-based rollout.
  • User segmentation.
  • Percentage-based releases.
  • Integrated authentication and payments.

Engineering highlights

  1. Frontend to database

    A React frontend over a NestJS and MongoDB backend, deployed on Vercel.

  2. Rollouts three ways

    A flag can be scoped by environment, by user segment, or released to a percentage of users.

Outcome

  • Live at flagit.app with auth and payments in place.
