• •Anthropic restricts Claude Pro and Max subscribers from using flat-rate plans with third-party AI agent frameworks.
• •The change, effective April 4, 2026, forces users to pay-as-you-go, potentially increasing costs dramatically.
• •OpenClaw, a popular open-source AI agent framework, is particularly affected by this change.
• •Anthropic's move aims to control customer relationships and drive usage within its own ecosystem.

Anthropic has blocked Claude Pro and Max subscribers from using their flat-rate plans with third-party AI agent frameworks, like OpenClaw, shifting costs to a pay-as-you-go model.

The decision, seen as a betrayal by the creator of OpenClaw, which moved to OpenAI, is part of Anthropic's strategy to control the revenue, data, and governance of its customer relationships. Anthropic is pushing developers towards its ecosystem by incentivizing the use of its own Claude Code environment.
