Featureflow
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.
