The short version

  • Only Buildkite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildkite free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention; Langfuse billing is metered per unit, where a unit is any trace, observation, or score sent to the platform; the free Hobby tier includes only 50,000 units per month before graduated per-unit charges apply, as of August 2026.
