The short version

  • Only Refact has a free tier, so it costs nothing to try first.
  • Each has a real cost: WarpBuild per-minute pricing requires tracking usage to estimate monthly costs; Refact requires configuration for optimal performance
  • They diverge on capability: WarpBuild covers Optimized runner infrastructure, Refact covers Autonomous agent workflows.

Where each one falls short

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

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer

Refact

  • Requires configuration for optimal performance
  • On-premise deployment adds operational complexity
  • Free tier limited by daily agent request quota
  • Coin system adds complexity to cost calculation
