TL;DR

  • typical API spend on OpenCode: about $30/month ($360/year).
  • Freebuff CLI: $0/month with models and subagents included.
  • Net savings: $360/year before API or credit overages.
  • Modeled example — your usage may differ.

Terminal agents are where subscription and token costs add up fastest. Here is the math for OpenCode vs Freebuff CLI — not a fabricated testimonial, but the switch we see often.

The bill on typical API spend#

OpenCode is free software but BYOK — most users pay $20–$50/mo to model providers depending on volume. For this example: $30/month or $360/year.

  3. 3Cancel OpenCode billing once you have verified Freebuff on your repos.

Do I need to change editors?+
No. Freebuff runs in whatever terminal you already use.
