The short version

  • Only Visual Studio Code 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.; Visual Studio Code requires extension installation for language-specific features and tooling
