What Is Unleash? Features, Pricing & Alternatives

Overview

Unleash is an open-source feature management platform that can be self-hosted or used as a hosted service. Unleash Open Source is free, self-hosted and has no seat limit, but is restricted to one project, two environments and 5,000 flags per instance, and excludes SSO, SCIM, granular role-based access, change-request approvals and a support SLA^[11]. Self-hosting keeps flag configuration and user context inside the customer’s own environment, a common reason for choosing it in regulated sectors.

The commercial product is sold in two ways. Enterprise Pay-As-You-Go costs US$75 per seat per month, billed monthly by credit card without a contract, available hosted or self-hosted (with a five-seat minimum for self-hosted); the cloud version includes 53 million API requests per month, then US$5 per million, a 99.9% uptime commitment and 90 days of feature metrics^[11]. Enterprise annual contracts are quoted per customer, support cloud, self-hosted or hybrid deployment, and offer a 99.99% uptime commitment and add-ons such as a hosted private instance and multi-region Enterprise Edge^[11]. A 14-day trial requires no card^[11]. The seat-based price is predictable but grows with large engineering teams, and experimentation features are lighter than in Statsig or Optimizely.
