Featurevisor vs Zenmanage

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.

Zenmanage is a feature flag management platform for controlling feature releases and changing application behavior at runtime. It supports boolean, string, and numeric flags, with default values and fallbacks for when the service cannot be reached. Teams can target flags using user or application context, group contexts into reusable segments, and release features gradually through percentage ramps and cohorts. Remote configuration allows behavior changes without redeploying code.

The service is available on the web and through an API. Listed SDKs cover JavaScript/TypeScript, PHP, Laravel, Python, Go, and .NET; REST APIs and webhooks are also listed. The Management API can create and update flags and targeting rules, and read audit history with scoped Bearer tokens. Permissions can be limited by account, project, or environment, including restrictions on production changes. Audit records include actor and environment details, and the maker says they cannot be edited or deleted. Zenmanage offers a free plan and paid plans from $29/mo, plus a 30-day Team-feature trial with no credit card required.
