Spin it! Jumpstart your Wasm journey with Fermyon Spin
summary
Fermyon Spin claims a Wasm serverless runtime built on Wasmtime with language SDKs (examples in Rust) and a simple developer toolset: Spin CLI compiles and runs Rust to Wasm, serves on port 3001 in the demo, and exposes HTTP triggers plus pub/sub. The demo stitches Wasm modules (sessions, votes) with containers for QR generation, uses queues, SendGrid and Slack for notifications, and reads secrets from HashiCorp Vault. The presenter cites ~15 million search results for “cold start times” to argue faster, smaller modules than containers.
