Claude subscribers will now have to pay extra to use OpenClaw

Claude users will now have to pay more to use third-party tools like the viral AI assistant OpenClaw, Anthropic announced.

The news came via email from Anthropic to Claude subscription holders. It was posted on Hacker News and states that as of April 4 at 12 p.m. PT, subscribers will "no longer be able to use your Claude subscription limits for third-party harnesses [tools] including OpenClaw. You can still use them with your Claude account, but they will require extra usage, a pay-as-you-go option billed separately from your subscription."
