From Barcelona to the edge 🌍

At Wasm I/O 2026, Erik Rose shared how the WebAssembly component model is powering faster, more secure, and language-flexible apps on Fastly Compute.

Highlights:
• No-recompile adaptation of WASI modules
• Network hops → near-instant function calls
• Python on Compute, made simpler with components

let-go is also a really interesting #clojure implementation.
It supports Clojure async. Go blocks are actual goroutines.
let-go includes an nREPL server compatible with CIDER (Emacs) and Calva (VS Code)
Compile your program to a self-contained HTML page with #wasm output or create a standalone binary.

WebAssembly in space!

The wasmtime runtime is being used aboard a satellite payload. It reached orbit about a week and will start being used soon after a commissioning test:

Fastly is doubling-down on developer control and code efficiency

We’ve removed the “duration” meter from Compute billing, moving strictly to vCPU milliseconds and request. This means your optimized code now directly lowers your bill.

New free tiers for:
-Fastly Compute
-KV Store & Secret Store
-Fanout

Available for immediate self-purchase. Build fast, build efficient. https://www.fastly.com/blog/shrink-your-bill-with-efficient-software

Wasmbox 0.3.2 released

network - Per-host outbound HTTPS via WASI HTTP. Host-filtered: tools can only reach hosts declared in their manifest. All other requests are rejected at the runtime level.

Cool tools coming!
