• 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.

• Unlimited experiments and seats, so nobody rations testing to save licence cost.
• Serious privacy posture with EU hosting and no data resale.
• Transparent, published pricing.

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

• Client-side only — no server-side experimentation.
• No feature-flag capability.
• Smaller vendor with a modest ecosystem.

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

Mid-sized e-commerce teams that want unlimited client-side testing with clean privacy handling.
