Conflicts & caveats

• Codeium does not officially support Cursor — use VS Code, JetBrains, Vim, or Neovim.
• Replit has its own built-in AI Agent — external integrations like Codeium cannot run inside the Replit web IDE.
• Codeium does not officially support Xcode. Use GitHub Copilot for Xcode or Direct API.
• Codeium has limited or no official Android Studio support. Use GitHub Copilot or JetBrains AI Assistant.
• Void Editor is BYO-API-key first — Codeium runs as an extension on top, which can work but isn't the intended Void workflow.
• Lapce has a small plugin ecosystem; Codeium may not have an official plugin yet.
• Codeium does not officially support RStudio — use direct API calls or the rstudio.cloud Copilot integration.
• Codeium does not officially support Spyder — use the direct API.
• Cursor Mobile only runs Cursor-managed agents and background tasks — local-only integrations like Codeium cannot run on the phone.
• Codeium does not officially support Apache NetBeans — Copilot and Tabnine are the main supported options.
• @codebase (Cursor) only works with Cursor built-in integration (yours is Codeium).
• Continue's codebase indexing only works when the integration is Continue.dev (yours is Codeium).
• Windsurf codebase indexing only works with Windsurf Cascade integration (yours is Codeium).
• Aider architect mode requires the Aider integration (yours is Codeium).
