- OpenClaw and other third parties were removed from the Claude subscription on April 4, 2026
- “These tools put a huge strain on our systems,” says Anthropic
- The OpenClaw founders criticize Anthropic for “lock[ing] out open source”
Anthropic has removed a number of third-party tools, including OpenClaw, from the standard Claude subscription effective April 4, 2026, meaning users who want to connect to OpenClaw and other third-party services will have to pay separately.
“Starting April 4th… you will no longer be able to use your Claude subscription limits for third-party harnesses, including OpenClaw,” the company wrote in an email shared by a customer (via Hacker news).
As existing subscription limits no longer apply to the use of these tools, users will have to undertake pay-as-you-go billing, prepaid usage packages or API costs to regain access.

OpenClaw can now be paid separately for Claude users
“To make the transition easier, we’re offering a one-time credit for additional usage equal to your monthly subscription price,” Anthropic added, which can be redeemed until April 17. Up to 30% off bundles are also offered.
The company likely made the change because Claude subscriptions were designed for human chat use, not autonomous agent workflows. with agentic tools like OpenClaw generating massive computing usage beyond what a typical human user would require, it puts Anthropic’s current model under pressure.
“We have been working to manage demand across the board, but these tools place an excessive strain on our systems,” the company added in its email.
Users are also promised the option to refund their subscriptions based on the fact that their terms have changed.
OpenClaw creator Peter Steinberger criticized Anthropic for “copy[ing] some popular features of their closed harness” and then “lock[ing] out of open source.
“Both me and Dave Morin tried to talk sense into Anthropic, the best we managed was to delay this for a week,” he added.
While the move may be distasteful to OpenClaw and Anthropic users, it marks a broader industry shift from flat-rate to usage-based as AI models and use cases evolve.
OpenClaw is an open source AI agent that runs on your own hardware and connects large language models (LLMs) like Claude or ChatGPT to the software and services you use every day.
Unlike a chatbot, it doesn’t stop at generating a response. It can take actions: read and write files, send messages, surf the web, execute scripts and call external APIs, all through well-known messaging apps like WhatsApp, Telegram or Slack.
