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 typical PaaS platforms 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.
