Anthropic Limits Claude Code Usage on Third-Party Tools, Introduces Pay-as-You-Go Pricing

Anthropic has tightened pricing rules for its coding assistant, affecting users who rely on third-party tools such as OpenClaw. The company informed customers that, effective April 4, subscribers to Claude Code will no longer be able to use their existing subscription limits when accessing the service through external “harnesses.”

Instead, such usage will be billed separately under a pay-as-you-go model.

The change marks a shift in how Anthropic manages consumption of its AI coding tools, particularly as third-party integrations grow in popularity.

In an email shared publicly, the company said the policy initially applies to OpenClaw but will extend to all similar tools in the near future.

Explaining the move, Boris Cherny, Anthropic Creator & Head, Claude Code, posted on X that the company’s “subscriptions weren’t built for the usage patterns of these third-party tools” and that Anthropic is working “to be intentional in managing our growth to continue to serve our customers sustainably long-term.”

The decision has sparked criticism from parts of the developer community. OpenClaw creator Peter Steinberger said he and others attempted to persuade Anthropic to reconsider, but only managed to delay the pricing changes by a week. He also criticised the timing, suggesting it coincided with Anthropic adding similar features to its own platform.

“Funny how timings match up, first they copy some popular features into their closed harness, then they lock out open source,” Steinberger said.

Cherny pushed back on that narrative, emphasising that the Claude Code team supports open-source development. He noted that he had recently contributed improvements to OpenClaw and said the changes were driven by “engineering constraints” rather than competitive strategy.

Anthropic is offering refunds to users who were unaware of the limitation.
