Why WASM?

Lightning-Fast Startup

WASM applications start in 0.52ms compared to 50ms+ for containers. Perfect for edge computing and serverless workloads where every millisecond counts.

Minimal Resource Footprint

WASM binaries are 1/100th the size of containers and use 20% less runtime resources. Deploy more workloads with less infrastructure.

Production-Ready WASI 0.3

With WASI 0.3 shipping in February 2026 with native async support, WASM is now ready for production server workloads beyond just edge functions.

AI-Native Deployment

Your AI coding agent can deploy WASM workloads through MCP just as easily as containers. Describe what you need, and let AI handle the deployment.

First-Mover Advantage

Open Source Cloud is the first and only open-source PaaS to offer WASM as a deployment target. Container-only platforms like Railway, Render, and Fly.io cannot match the startup speed and resource efficiency of WebAssembly.

With WASI 0.3 shipping in February 2026 with native async support, WASM is now production-ready for server workloads. Fermyon and Akamai are already seeing 0.52ms cold starts and 75M RPS at 4,400+ edge locations.

WASM Deployment Features

Deploy WebAssembly workloads just as easily as containers, with dramatically better performance characteristics.

WASM Runtime
