Comparison

Zenmanage vs Unleash

Unleash ships a free, self-hostable open-source edition alongside its paid plans. Here's how the two platforms compare, sourced from each vendor's own pricing and docs pages.

Both platforms support constraint-based targeting and reusable segments. The deployment model is the main divide: Zenmanage runs entirely as a hosted service, while Unleash's Open Source edition is free to run yourself, with paid tiers layered on top for scale and governance.

Choose Zenmanage if

  • You'd rather not run and upgrade a feature-flag server yourself.
  • Predictable per-plan pricing beats a per-seat rate on the paid tier.
  • Audit log and RBAC coming bundled with the hosted service matters more than free self-hosting.

Choose Unleash if

  • Self-hosting is a requirement and a free, unlimited-seat Open Source edition fits your needs.
  • Automatic rollback on a metric threshold (Enterprise's Impact Metrics with Safeguards) is a must-have.
  • You've reviewed the core server's AGPLv3 license (as of v8) and it fits your compliance model.

Targeting & segments Rule-based targeting on context attributes plus reusable segments, evaluated server-side with local rule caching in the SDKs. Constraint-based targeting (IN/NOT_IN, numeric, string, date, semver) plus reusable segments shared across flags.
Progressive rollouts Percentage-based progressive rollouts with scheduling and manual checkpoints. Gradual rollout strategy with consistent bucketing; Enterprise "Impact Metrics with Safeguards" adds automatic rollback on a metric threshold.
Audit log & RBAC Audit trail and role-based permissions on paid plans. Basic audit log and RBAC are available; full RBAC, change-request approval, and 2-year audit retention are Enterprise-only.
OpenFeature support No official provider yet — use a thin adapter around the Zenmanage SDK. Official providers for Node.js and Ruby; Java and Python providers are community-maintained.
MCP server Hosted MCP server at mcp.zenmanage.com on every paid plan — no install required. Official MCP server for creating, checking, and toggling flags from an AI coding assistant.
Self-hosting Cloud-only. No self-hosted or open-source edition. Yes — the Open Source edition is free to self-host. The core server license moved from Apache 2.0 to AGPLv3 as of v8; the published Docker images stay Apache 2.0.
