Featurevisor vs Rollgate

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.

Rollgate is a feature-flag platform for engineering teams, offering targeting, scheduled changes, gradual rollouts, and rapid rollback. Its SDK evaluates flags locally in process in under a millisecond, without a network hop for each evaluation. Twelve SDKs cover React, Vue, Angular, Svelte, browser, Node.js, Go, Python, Java,.NET, React Native, and Flutter. The REST API manages flags, projects, and users. Previous configurations, including targeting rules and rollout percentages, can be restored in under a second. A/B testing is available on Pro and above, with experiment events sent to Segment, Mixpanel, PostHog, or a webhook. Plans are Free at free, Starter at €45 a month, Pro at €119 a month, and Growth at €349 a month. Rollgate says data stays in Germany, remains in the EU, and uses TLS 1.3, AES-256 at rest, scoped API keys, and audit logging. Self-hosting is not currently available.
