In their own words
feat
feat is a hosted feature-flag platform for early engineering teams. Server SDKs evaluate flags locally, so each flag read does not require a network call; changes stream to connected SDKs in under a second. Targeting rules combine conditions across users, devices, organizations, sessions, and requests using AND and OR. Sticky percentage rollouts keep a user, device, or organization on the same variation across requests and sessions. First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart, with OpenFeature providers for web, Node.js, and Dart. Metric sources include Segment, Mixpanel, PostHog, and custom sources. The Free plan costs nothing and includes 7,500 MAU, 100 server connections, two projects, unlimited environments, and unlimited flags. Starter costs $19 a month, with annual billing listed at $15/mo. Built-in statistical experiments, variant tracking, metric integrations, auto-advance gradual rollouts, and Slack integration are listed as coming in Q3 2026, not current features.
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.
