  • Each has a real cost: Cline enterprise tier pricing is gated behind a sales contact; only the open source free tier and usage based inference credits are self serve, as of August 2026.; Flagsmith the Free plan supports only a single team member, limiting collaboration for small teams.

Flagsmith
