What "BYOH" means on these cards

BYOH = Bring Your Own Harness. A deal is marked BYOH when the API key or subscription auth it provides can be plugged into an external coding agent like OpenCode, Cline, ForgeCode, Roo, or any OpenAI-compatible tool. The opposite is "Locked in", meaning the plan only works inside the vendor's own agent. For most harness users, BYOH plans are strictly more flexible.
