Unleash vs ConfigCat
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
From $75 per seat/month (Pay-As-You-Go, 5-seat minimum self-hosted)
Free tierFrom $110 per month (Pro)
Free tierWhat drives the bill
The metric that actually scales your invoice.
Self-hosted open source is genuinely free within its project and environment caps. Pay-As-You-Go includes 53M API requests a month with $5 per additional million; Enterprise is an annual custom contract adding SSO, audit and change requests.
Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.
Free tier
Open-source edition is free and self-hosted with no seat limit, but capped at 1 project, 2 environments and 5,000 flags.
Free forever plan with a monthly config-request allowance and unlimited members.

Strengths
- Local evaluation means no user data leaves your infrastructure — a strong GDPR position.
- Mature, well-documented open-source core with no artificial crippling.
- Kubernetes and Terraform support for infrastructure-as-code workflows.
- Unlimited team members at every tier, so product and support can toggle flags too.
- Very simple to adopt — an afternoon, not a project.
- Broad SDK coverage including Dart and Elixir.
Limitations
- Experimentation and analytics are thin; it is a flag system first.
- Self-hosting means you own uptime for something in your request path.
- Smaller ecosystem than LaunchDarkly.
- No experimentation or analytics to speak of.
- Limited targeting sophistication compared to LaunchDarkly.
- Small vendor.
Best for
