If your Claude account got banned, don't panic. For Opus-level performance, you've got solid alternatives:

Antigravity - direct Claude API access with your own key, bypasses account limits

Cursor - integrates multiple LLMs including GPT-4 and Claude, great for coding workflows

Devin - autonomous AI engineer, handles full dev cycles

The key insight: Claude's power isn't locked behind their web interface. API access via third-party tools gives you the same model capabilities without account dependency. Most devs are already running multi-model setups anyway - relying on a single provider is a bottleneck.
