- Scenario B (~10 server envs/connections, 10K client MAU, ~2–5M evaluations/mo): LaunchDarkly Foundation 10 SC + 10K MAU = $150; Statsig Pro 5M events = $150; Flagsmith Start-Up = $45. Units differ — list price, not a quote.

- Can I compare these units directly?
- Only loosely. LaunchDarkly bills service connections + client MAU; Statsig bills metered events (flag checks unlimited); Flagsmith bills API requests on /flags, /identities, /traits, /environment-document plus seats on Scale-Up. Map your own workload to each unit.
