FeatBit vs Featurevisor

FeatBit is an open-source feature-flag platform for controlling releases, experiments, and self-hosted delivery. Flags let teams separate code deployment from feature release, target users, roll changes out progressively, and roll back instantly. It supports feature-level A/B testing and describes an AI release decision agent for hypotheses, measurement, and continue, pause, or rollback choices. SDKs cover JavaScript and TypeScript, React, React Native, Node.js,.NET, Java, Python, Ruby, Go, Rust, and OpenFeature providers. Listed integrations include Datadog, New Relic, Grafana, GrowthBook, Slack, and OpenTelemetry. Self-hosting supports Docker Compose, a REST API, webhooks, and real-time WebSocket updates. FeatBit Cloud runs on Microsoft Azure. The Cloud Free plan allows 1,000 MAU; Foundation self-hosting is free without listed seat, MAU, project, or connection limits. Self-host Enterprise costs $3,999 a year.

Featurevisor is a Git-based tool for managing feature flags, experiments and remote configuration through YAML files in a Git repository. Teams build datafiles for each environment, deploy them and evaluate features through an SDK. Rules can target users in order, roll out a percentage and assign weighted experiment variations. Typed global and feature variables allow defaults and targeted overrides, with schemas validated during datafile builds. Applications fetch static JSON datafiles and evaluate flags locally in memory, without a network request for each decision; the datafiles are served from the customer’s own CDN. YAML test specifications can check expected behavior locally or in CI, with failed assertions returning a non-zero exit. Git pull requests and CI linting, tests and builds provide change control. Featurevisor is self-hosted and MIT-licensed. Its free plan is free, with no per-seat pricing or evaluation service to keep running. Listed platforms include Android, iOS, Linux, macOS, web and Windows.
