Gate News reports that on March 20, co-founder of open-source AI programming tool OpenCode, Dax Raad, announced that due to legal demands from Anthropic, all Anthropic-related integrations will be removed from version 1.3.0 of OpenCode. The removals include Anthropic prompt files, the built-in authentication plugin opencode-anthropic-auth, provider enums, and references to Anthropic in provider hints. The related plugins have been deleted from GitHub and marked as deprecated on npm.
Dax Raad stated on X that the team had tried to persuade Anthropic to support developers’ freedom of choice, but “they sent lawyers,” and praised OpenAI, GitHub, and GitLab for “supporting developer freedom.”
OpenCode, developed by Anomaly, has over 126,000 stars on GitHub, surpassing Anthropic’s official Claude Code with about 80,000 stars, making it one of the most popular open-source AI programming terminal tools. Previously, some users reported being banned when logging in via Anthropic OAuth with OpenCode. After this removal, the community has begun developing a third-party replacement plugin, opencode-claude-auth.
