The short version

  • Only GitHub has a free tier, so it costs nothing to try first.
  • Each has a real cost: GitHub acquired by Microsoft in 2018, reducing pure independence despite operational autonomy; 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.
