FeatBit is a self-hosted, open-source feature-flag platform with built-in experimentation for teams that want LaunchDarkly-style progressive delivery while keeping flag data on their own infrastructure.[1]
Quick verdict
Teams that must keep flag data on their own infrastructure get the most from FeatBit: its MIT-licensed stack pairs LaunchDarkly-style targeting with built-in experimentation and no seat or usage metering on self-host. The decisive constraint is operational: you run the deployment and its backing services yourself, and SSO, audit logs, and advanced RBAC require the $3,999-per-year Enterprise plan.[1][2]
Key features
Advanced targeting and segmentation Ship behind toggles with advanced targeting and segmentation, rolling features out to slices of users instead of all-or-nothing deploys.[1]
Local evaluation plus real-time client SDKs Evaluate flags locally with server-side SDKs for .NET, Go, Java, Python, Node.js, and Rust, while client-side SDKs for JavaScript and mobile receive real-time updates over streaming connections.[1]
Built-in experimentation and A/B testing Run A/B tests and experiments with metrics, layers, and statistics APIs on top of the same flags, so rollout and measurement share one workflow.[1]
REST API, Terraform, CLI, and webhooks Manage flags as code through a resource-organized REST API with OpenAPI documentation, plus webhooks, a Terraform provider, a CLI, and relay-proxy auto-sync agents.[1]
Separated evaluation and management APIs Give each service its own key: DataSync, Evaluation, and Experience APIs carry distinct authentication so evaluation traffic stays separate from management traffic.[1]
Docker Compose quickstart in minutes Deploy in minutes from a Docker Compose quickstart, with standalone, standard, and professional compose variants for different scales.[1]
No seat or usage limits on self-host Keep every seat and every flag free of metering: self-host plans carry no limits on seats, MAU, projects, flags, or service connections.[1]
MIT-licensed and openly forkable Fork and audit the whole stack under the MIT licence, with the repository, quickstarts, and community channels open on GitHub, Discord, Slack, and X.[1]
Who will love it
Self-hosting teams that must keep flag and experiment data inside their own boundary: the MIT stack runs on your infrastructure with no seat or MAU metering.[1][2]
Teams combining rollout and measurement: flags, targeting, metrics, layers, and statistics APIs live in one platform instead of two vendors.[1]
Platform teams managing flags as code: the REST API, Terraform provider, CLI, webhooks, and relay-proxy agents fit infrastructure-as-code workflows.[1]
Who should avoid it
Teams that want a fully managed SaaS with zero infrastructure to operate: self-hosting means you run the deployment and its backing services yourself.[1][2]
Non-technical teams needing click-only flag control: SDK integration, API management, and self-operation assume developer and operator skills.[1]
Teams needing single sign-on, audit logs, or advanced RBAC without a paid tier: those controls sit on Enterprise plans, not the free Foundation plan.[1]
Alternatives and compatibility
Choose FeatBit when flag data must stay on your infrastructure and your team can operate the deployment; the free Foundation plan covers the full flagging and experimentation workflow without seat or usage meters.[1][2]
Budget for Enterprise at $3,999 per year when the organization requires single sign-on, audit logs, advanced RBAC, and priority support rather than community channels.[1]
Prefer a managed SaaS flag service when operating Postgres-class backing services and relay agents is more burden than the licence saving is worth; no catalogue relationship is asserted here either way.[1]
Questions worth asking
What is the best FeatBit alternative for non-technical users?
Is FeatBit really no-code?
No. Flag control is a developer and operator workflow through SDKs, a REST API, a Terraform provider, and a CLI. The docs assume code-level integration and self-operated infrastructure, not click-only administration.[1]
How much does FeatBit cost per month?
Self-hosting is free forever on the Foundation plan ($0), including unlimited seats and usage-metered items. Enterprise costs $3,999 per year and adds single sign-on, audit logs, and priority support; Enterprise Premium is custom-priced. There is no per-seat monthly meter on self-host.
