What is Krysta Wing?

Krysta Wing focuses on creating a reliable execution layer specifically designed for AI agents that generate and run their own code. The system spins up isolated environments quickly to handle tasks without risking broader infrastructure. Core operations include executing scripts in protected spaces, streaming standard output directly back through live connections, and validating results against defined rules before any further actions occur. This sequence ensures controlled and observable behavior during agent workflows. Additional capabilities support policy enforcement on outputs and integration with various backend technologies for state management and metrics tracking, making it suitable for development and deployment of agent-based applications.

Isolated microVM sandboxes for AI-generated code
Real-time stdout streaming via WebSocket
Policy enforcement and output validation
Millisecond-scale microVM provisioning
Dependency resolution and mounting
Built on Apache Kafka, Upstash Redis, Vercel
No cold start wait

What you can use Krysta Wing for
