Anthropic Blocks OpenClaw Access to Claude Subscriptions – Founder’s Fiery Response

Claude Code founder Boris Cherny announced that, starting at 12 p.m. PT, Claude subscriptions (including Claude Max) will no longer include usage quotas for third‑party tools such as OpenClaw.

OpenClaw, an open‑source client praised for its flexibility, previously allowed users to log in with a Claude account and consume their subscription quota directly. That pathway is now blocked.

Boris explained that Anthropic is coping with rapidly growing Claude demand, but the subscription service was not designed for the usage patterns of third‑party tools, so they must prioritize direct official product and API users.

Existing subscribers receive a one‑time credit equal to their monthly fee.

Additional usage packs can be purchased at a discount to continue using third‑party tools.

Affected users will receive an email the next day and can request a full refund.

Anthropic assured users that accounts will not be banned; only email notifications will be sent.

The most notable reaction came from OpenClaw co‑founder Peter Steinberger ("lobster" emoji on his Twitter), who posted:

"I and @davemorin tried to persuade Anthropic, and we only managed to delay this by a week." "The timing is really delicate; they first copy popular features into their closed framework, then kick the open‑source out."

Peter’s comment suggests Anthropic incorporated OpenClaw‑like functionality into official products such as Claude Code, and once the official version is stable, they cut off third‑party alternatives.

Boris later noted that he had just submitted several PRs to OpenClaw to improve prompt‑cache efficiency, showing technical support for the project despite the commercial restriction.

A screenshot showed a user canceling a Claude Max subscription, citing "Claude doesn't have the features necessary for my work" and attaching Anthropic’s announcement as a note.

Community backlash focused on several points:

Users questioned the claim that demand growth is tied to third‑party usage, asking why token consumption is the same.

Boris replied that the issue is not token count but that the subscription system is optimized for specific usage patterns, which third‑party tools do not follow.

Technical observers noted that batch calls, long sessions, and special prompt structures differ from typical official‑interface usage, affecting backend scheduling and cache optimization.

Some accused Anthropic of commercial lock‑in, noting that Anthropic’s own Claude Cowork directly competes with OpenClaw.

Criticism also targeted the abrupt notification; refunds are offered, but the change took effect in less than 24 hours.

When asked whether Claude Code, Claude Code headless, and Agent SDK can still use subscription quotas, Boris confirmed they can, clarifying that Anthropic’s own toolchain is exempt.
