The short version

  • Only Jenkins has a free tier, so it costs nothing to try first.
  • Each has a real cost: Jenkins described by the vendor as the leading open source automation server and a community-driven project, with no commercial edition or license fee; LangSmith usage beyond the included trace allotment is billed in LangChain Compute Units at $1.50 per LCU and Storage Units at $1.00 per LSU, an unfamiliar metering unit compared to flat per-seat pricing, as of August 2026.
