The short version

  • Only TeamCity has a free tier, so it costs nothing to try first.
  • 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.; TeamCity detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

TeamCity

  • Detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.
  • Self-hosted setup and agent management require more operational overhead than fully managed CI/CD services.
  • Additional build agents and users are priced incrementally, which can add up for larger teams.
  • The UI and configuration model have a steeper learning curve compared to YAML-first CI tools.
