Anthropic Blocks OpenClaw Use on Claude Subscriptions, Forcing Pay-As-You-Go Fees

Anthropic blocked Claude Pro and Max subscribers from using third-party AI agent frameworks, starting with OpenClaw.

The creator of OpenClaw, Peter Steinberger, called the decision a betrayal of open-source developers.

More than 135,000 OpenClaw instances were estimated to be running at the time of the announcement.

Anthropic's subscriptions weren't built for the usage patterns of these third-party tools, said Boris Cherny.

Steinberger had recently joined OpenAI, which has opted to integrate OpenClaw into its offerings.

OpenClaw was originally released in November 2025 as Clawdbot and went viral among developers.

The project was renamed twice after Anthropic raised trademark concerns.

The framework supports more than 50 integrations and works across multiple AI models.

Tencent built an enterprise platform directly on top of it.

Anthropic's decision forced thousands of users to face cost increases of up to 50 times their previous monthly outlay.

The announcement elicited mixed reactions from users.

OpenClaw creator Steinberger posted that first they copy features, then they lock out open source.

Anthropic offered a one-time credit equal to one month's subscription fee.

The ban is part of a broader trend in the AI industry toward tighter control over third-party integrations.

OpenAI stands out as a notable exception, continuing to provide subsidized tokens.

Anthropic is focusing on developing proprietary tools.

Users who depended on OpenClaw face limited, costly options.
