Open source feature management for confident, low-risk deployments
Feature toggle and progressive rollout platform enabling development, SRE, and operations teams to ship features, run A/B tests, and manage configurations with confidence.
FeatureProbe is a feature management service built for teams who need to ship faster while maintaining control. Born from 5+ years of production use supporting 5,000+ developers and million-user products, it brings enterprise-grade feature flagging, progressive rollouts, and A/B testing to teams of any size.
Development teams eliminate branch-merge overhead by gating features on the main branch. SRE teams reduce MTTR by toggling problematic services without code deployments or developer escalations. Operations teams configure and target features through a comprehensive UI, rolling out changes to specific user segments based on geolocation, attributes, or custom rules—all without engineering involvement.
The platform separates concerns cleanly: a management portal for configuration and analytics, a high-performance server for flag evaluation, and SDKs for 11+ languages spanning server-side (Java, Rust, Go, Python, Node.js) and client-side (JavaScript, React, Android, iOS, Flutter, Mini Program) environments. Deploy via Docker Compose in minutes, then scale as your traffic grows. Apache 2.0 licensed for maximum flexibility.
When teams consider FeatureProbe, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Trunk-based development without branch chaos
Development teams merge to main continuously, using feature toggles to gate incomplete work and eliminate costly branch-merge cycles.
Instant incident mitigation by SRE
SRE disables problematic features via UI during incidents, reducing MTTR without code deployments or waking on-call developers.
Production testing with controlled user exposure
QA and product teams validate new features with 5% of production traffic, gathering real-world feedback before full rollout and saving test environment costs.
Geo-targeted feature rollouts for operations
Operations team launches regional promotions or compliance features to specific markets through UI targeting rules, no engineering required.
FeatureProbe provides Docker Compose configuration for self-hosted deployment. Clone the repository, run docker compose up, and access the portal on localhost:4009 with default credentials (admin/Pass1234).
Server-side SDKs include Java, Rust, Go, Python, and Node.js. Client-side SDKs cover JavaScript, React, Android, iOS, Flutter, and Mini Program. All SDKs follow similar integration patterns for consistent developer experience.
Yes. FeatureProbe includes built-in A/B testing capabilities with metric analysis and traffic monitoring dashboards, enabling operations teams to compare strategies and measure impact directly in the platform.
Feature toggles allow SRE teams to disable problematic services or trigger degradations instantly through the UI, containing issues without code deployments or developer intervention during incidents.
FeatureProbe is licensed under Apache 2.0, providing permissive terms for commercial and non-commercial use, modification, and distribution.
