Claude Code third party harness ban for OpenClaw subscriptions

April 4, 2026ℏεsam, Yuchen Jin, Matthew Berman

Multiple creators report Anthropic blocked using Claude subscriptions through third-party harnesses like OpenClaw, pushing users to API keys or extra usage credits and triggering backlash about enforceability, pricing, and ecosystem lock-in.

Anthropic just sent an email saying that you can no longer run 3rd party harnesses like OpenClaw using Claude subscriptions.
It’s over. Officially.
No more Claude in OpenClaw.
