In their own words
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.
GO Feature Flag
GO Feature Flag is an open-source feature-flag management system built on OpenFeature for infrastructure you control. Its relay proxy runs locally with Docker and a flag configuration file. Teams can target users and segments, use percentage or progressive rollouts, schedule changes, and run A/B tests. Client and server SDKs are listed for 16 languages and frameworks, including JavaScript, TypeScript, React, Swift, Kotlin, Go, Java, Python,.NET, Ruby, Rust, and others. Retrievers load configuration from HTTP(S), local files, Kubernetes ConfigMaps, cloud storage, Git providers, MongoDB, Redis, and PostgreSQL. Exporters send evaluation data to Kafka, AWS S3, BigQuery, OpenTelemetry, webhooks, or logs. Notifications can reach Slack, Discord, Microsoft Teams, webhooks, or logs. The MIT-licensed Opensource plan costs nothing, billed forever, with all features, unlimited flags, and community support.
