Elastic infrastructureforAI agents
Bring your stack. Scale to millions.
Deploy without rewrites
Bring Node.js, Python, PHP, and more without rewriting for edge-specific runtimes.
Sandboxed execution
Run untrusted, user-submitted, and AI-generated code inside secure WebAssembly sandboxes.
Sub-5ms cold starts
The only platform with <5ms cold-start response times for Node.js and Python apps.

Everything you need, all in one place
Built-in infrastructure blocks for shipping, scaling, and operating production apps without stitching services together.
From commit to app
Stateful apps at the edge
Production workflows
Trusted by teams shipping production AI and hosting products
Pay only when your code runs
Slow model calls, webhook pauses, and hibernating WebSockets should not count as compute. StackMachine meters CPU work, not wall-clock wait time.
Fast global access
Run close to users and tool calls with a network designed for short-lived, dynamic workloads.
Serverless scaling
Traffic bursts are absorbed automatically, then capacity scales down when work is complete.
More isolated apps on the same hardware.
Containers replicate OS and runtime state per tenant. WebAssembly shares executable binaries across isolated tenants, unlocking an order of magnitude higher compute density.
Each dot represents an isolated application instance. Same server. Same hardware. 400x more density.
How we compare
Run real app runtimes in secure Wasm sandboxes with sub-5ms cold starts and density built for massive scale.
