How Flagsmith bills you
The pricing model is per request (api calls). Open-source (BSD-3) flag platform with a strong self-hosted story via Docker/Kubernetes plus a managed cloud and an MCP server for AI agents. Best suited to: open-source, self-hostable feature flags + remote config.
What to watch for on the bill
- On-prem/private hosting and SCIM/LDAP gated behind custom-priced Enterprise tier
- Switching between environments to manage flags can feel clunky
