Featureflip provides feature flags for changing functionality in a running application without deploying new code. It supports percentage rollouts, targeting rules, kill switches, A/B tests, and isolated environments.

Teams can manage flags through a REST Management API or evaluate them through the Evaluation API; thirteen SDKs and OpenFeature providers are listed. Server SDKs evaluate locally from in-memory configuration and keep using the last configuration if the service is unreachable. Featureflip also offers an MCP server for Claude Code, Cursor, Copilot, and Cline, plus a Terraform provider. Its service and PostgreSQL database run on Hetzner Cloud in the European Union. The Free plan is free and is limited to one project, 10 flags per project, two environments, and up to three team members. Team is $49 a month; Pro is $99 a month; Business is $249 a month. Enterprise pricing is negotiated directly.
