Anthropic is changing how it bills for its Claude Code service. The company told customers they must now pay extra to use the coding assistant with third-party tools like OpenClaw.
According to a customer email shared on Hacker News, the new policy took effect at noon Pacific on April 4. Claude Code subscribers can no longer apply their subscription limits to “third-party harnesses including OpenClaw.” Instead, they must use a separate pay-as-you-go option. Anthropic said the policy applies to all similar tools and will expand to more soon.

Engineering Constraints Drive Change
Boris Cherny, Anthropic’s head of Claude Code, explained the move on X. He stated the company’s subscriptions were not designed for the usage patterns these external tools create. “We’re trying to be intentional in managing our growth to continue to serve our customers sustainably long-term,” Cherny wrote.
He framed the decision as a technical necessity. “This is more about engineering constraints,” Cherny said. He added that Anthropic is offering full refunds to affected users who didn’t realize the service wasn’t officially supported. The company is attempting to make its policy “clear and explicit.”

Cherny also sought to deflect criticism of being anti-open source. He noted Claude Code team members are “big fans” of the model and claimed he recently submitted pull requests to improve OpenClaw’s prompt cache efficiency.
OpenClaw Creator Joins Rival OpenAI
The pricing shift follows significant personnel movement. OpenClaw creator Peter Steinberger recently announced he was joining Anthropic rival OpenAI. He stated OpenClaw will continue as an open-source project with OpenAI’s support.
Steinberger suggested the timing was not coincidental. He posted that he and OpenClaw board member Dave Morin “tried to talk sense into Anthropic” and only secured a one-week delay for the new fees. “Funny how timings match up, first they copy some popular features into their closed harness, then they lock out open source,” Steinberger said.
This comment points to rising tensions in the competitive AI coding assistant sector. Developers are a key battleground for AI firms.
Broader Market Context
Anthropic’s policy adjustment occurs as competitors also refine their strategies. OpenAI recently shut down its Sora app and video generation models. Reports suggest this was to free up computing resources. The move is part of a broader effort to refocus on attracting software engineers and enterprise clients.
These clients increasingly rely on products like Claude Code. The market for AI-assisted development tools is growing rapidly. Firms are now shifting from pure user acquisition to defining sustainable business models.
What this means for developers is clearer cost structures but potentially higher bills. The pay-as-you-go model offers flexibility but removes the predictability of a flat subscription fee. This could push some users to evaluate alternative platforms or revert to using base model APIs directly.
Industry watchers note that as AI services mature, pricing and access changes are inevitable. The initial phase of broad access is giving way to more segmented and tiered offerings. Anthropic’s move signals a focus on managing infrastructure costs and aligning revenue with specific high-usage patterns.
