The short version

  • Each has a real cost: 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.; 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.
