Fast, Scalable, Fully Isolated Environments for AI Agents and More

At Koyeb, we provide high-performance serverless infrastructure for intensive applications across CPUs, GPUs, and accelerators. We take code, build it, and run it in fully isolated, secure microVMs on bare-metal servers around the world. We scale automatically when needed, down to zero when idle, with cold starts as low as 250ms.

Ϟ Executing untrusted or user-generated code securely
Ϟ Prototyping applications quickly
Ϟ Testing APIs or libraries in clean environments
Ϟ Demonstrating functionality without configuring local infrastructure
