Windsurf
Windsurf is the world's first agentic IDE featuring Cascade, an AI agent that combines deep codebase understanding with real-time awareness of your actions to enable autonomous, collaborative coding workflows.

Refact.ai offers self-hosted AI coding assistance for enterprises needing data privacy. Run AI models on your own servers, ensuring code never leaves your infrastructure. Features include on-premise deployment, custom model training on your code, chat assistance, code completion, and fine-tuning on private repositories. Supports open-source models and commercial models. Ideal for regulated industries, enterprises with security requirements, or companies wanting to train AI specifically on their proprietary code. More setup than cloud services but provides complete control and privacy guarantees.
