HarnessRouter suits developers who want to put Codex, Claude Code or Hermes behind one API in their own product and pay only for active agent-work minutes plus model usage at catalog price.
HarnessRouter pairs a monthly fee with included usage and per-minute agent work. Free costs nothing, with no card and no expiry, but caps you at 30 agent-work minutes, 2 concurrent tasks and 7-day task records. Developer is $20 per month with $20 of usage included, unlimited concurrent tasks and 1 workspace; agent work then runs at $0.014 per minute. Production is $200 per month with $200 of usage included, 5 workspaces and agent work at $0.010 per minute.
Scale is $1000 per month with $1,000 of usage included, agent work at $0.006 per minute and tracing included while it is in beta. Higher plans also discount top-up rates: 30% off on Developer, 50% on Production and 70% on Scale. Enterprise is custom-priced with custom usage, volume and terms. Prices checked on 2026-10-01.
