Console’s review

· Reviewed by David Mytton

What we like

Easy to self-host in a single container backed by SQLite, but can scale horizontally by connecting MySQL, Postgres, etc + load balancer. Official client libraries for a range of languages. Can split the audience into segments for conditional flagging. Supports gradual rollouts as a %.

Tradeoffs

Docs are primarily about deploying & running Flipt rather than explaining how to use the core feature flag functionality.
