From $45 per month (indicative, Start-up plan)

• Genuinely easy self-hosting with a Docker image and Helm chart.
• Simple, comprehensible pricing.
• Remote config alongside flags, which covers a lot of mobile use cases.

• Extremely reliable flag delivery with offline fallbacks — this is infrastructure you can trust in the request path.
• Best-in-class governance: approval workflows, audit logs, role-based access.
• Code references and stale-flag detection actually help you remove dead flags.

• Experimentation features are basic.
• Smaller company and community than the leaders.
• Fewer governance controls for large organisations.

• The most expensive option in the category by a distance.
• Experimentation is competent but less sophisticated than dedicated statistics platforms.
• No meaningful free tier for evaluation.

Teams wanting straightforward flags without LaunchDarkly pricing or Unleash's operational depth.

Engineering organisations where flags are critical infrastructure and governance is required.
