The short version

  • Only Prettier has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
