Featureflip vs Rollgate

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. When a flag is no longer needed, its GitHub Action can open a reviewable pull request to remove the code path across thirteen languages and archive the flag after merge. 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.

Rollgate is a feature-flag platform for engineering teams, offering targeting, scheduled changes, gradual rollouts, and rapid rollback. Its SDK evaluates flags locally in process in under a millisecond, without a network hop for each evaluation. Twelve SDKs cover React, Vue, Angular, Svelte, browser, Node.js, Go, Python, Java,.NET, React Native, and Flutter. The REST API manages flags, projects, and users. Previous configurations, including targeting rules and rollout percentages, can be restored in under a second. A/B testing is available on Pro and above, with experiment events sent to Segment, Mixpanel, PostHog, or a webhook. Plans are Free at free, Starter at €45 a month, Pro at €119 a month, and Growth at €349 a month. Rollgate says data stays in Germany, remains in the EU, and uses TLS 1.3, AES-256 at rest, scoped API keys, and audit logging. Self-hosting is not currently available.
