| Deployment | Datafiles are served from the customer’s own CDN, with no vendor in the request path. | Unleash Enterprise is offered as hosted cloud, self-hosted, or hybrid, with a hosted private instance available as an Enterprise add-on. |
| Feature flags | Boolean flags use ordered targeting rules whose first matching rule determines the result. | Flags belong to projects and can have different activation strategies in each environment. |
| SDK coverage | Official SDKs are listed for JavaScript, React, React Native, Vue, Next.js, Go, Python, PHP, Ruby, Java, Kotlin, Swift, Rust and Elixir. | Documentation lists server SDKs for Node.js, Java, Go, Rust, Ruby, Python, .NET and PHP plus frontend SDKs for JavaScript, React, Next.js, Vue, iOS, Android and Flutter. |
| What it does | Featurevisor manages feature flags, experiments and remote configuration as files in Git, then builds datafiles consumed by SDKs. | Unleash controls feature releases at runtime so teams can deploy code separately from enabling functionality for users. |

In their own words
Featurevisor
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.
Unleash
Unleash is a feature management platform for controlling software behavior and releases in production without redeploying code. Teams can stage progressive rollouts, roll back instantly, apply release templates, and use kill switches. Its experimentation tools include A/B/n testing, flag variants, user segmentation, and stickiness. Flags are evaluated in SDKs or at the edge rather than on the Unleash server. The service lists more than 25 SDKs, including options for Node.js, Java, Go, Python,.NET, React, Android, and iOS. Listed integrations include Slack, Teams, Datadog, Jira, webhooks, and Admin, Frontend, and Client APIs. The free Open Source instance allows no seat limit but is restricted to one project, two environments, and 5,000 flags; it lacks SSO, SCIM, granular RBAC, change-request approvals, and a support SLA. Pay-As-You-Go costs $75 a month, billed monthly, and has a 14-day trial without a credit card. Enterprise can be hosted, self-hosted, or hybrid, with US or EU data residency available.
