Anthropic Restricts Claude Subscriptions for Third-Party Integrations Like OpenClaw

Summary

Anthropic announced that starting April 4, 2025, Claude subscription limits will no longer apply to third-party harnesses and integrations, including the popular OpenClaw tool. Users seeking to access Claude through these third-party platforms will need to enable pay-as-you-go extra usage, which will be billed separately from their subscription. The move affects all third-party harnesses, with OpenClaw being the initial target before the policy rolls out more broadly.

To ease the transition, Anthropic is offering a one-time credit equal to users' monthly subscription price, redeemable by April 17. The company is also introducing discounts for pre-purchasing extra usage bundles, offering savings of up to 30%. Anthropic cited capacity management concerns, noting that third-party integrations place "outsized strain" on their systems, and emphasized the need to prioritize users of core Claude products.

The policy change has implications for users who rely on third-party tools to access Claude's capabilities, as they will face additional costs unless they switch to official Claude products like Claude Code and Claude Cowork. Anthropic has indicated that affected users will receive follow-up communication offering the option to refund their subscriptions if they prefer not to adopt the extra usage billing model.
