Featureflip vs Featureflow

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.

Featureflow manages feature releases for engineering and product teams. It separates deployment from release: teams can deploy code silently, then enable features later without another deployment. Targeting rules can use individual users, cohorts, dates, times of day and custom attributes. Teams can roll features out by percentage or environment, organize users into segments and use instant kill switches. Release pipelines arrange ordered phases with environment mapping, default targeting and approval gates. Integrations include Slack, Jira, CI/CD webhooks, a REST API and AI assistants through MCP. SDKs are listed for a broad set of server and client technologies, including Java, Node.js, Python, React Native, iOS and Android. Feature flag and user data are encrypted at rest in a SOC II compliant data centre. The free plan supports five seats, one project, two environments and one million SDK requests monthly. Team is $99 a month; Business is $399 a month. Enterprise pricing is custom, and the service lists a 14-day trial.
