Rent global compute from a grid of browsers — or earn by sharing yours
CloudXaaS distributes JS and WASM jobs across thousands of browser tabs worldwide. Like vast.ai, but browser-native — open a tab to become a node, or submit a job and pay only for what you use.
browser-native · zero install · sandboxed
How it works
Three steps from a browser tab to a global grid
Join
Open /join in any browser. Your CPU and RAM become a compute node running tasks in a sandboxed Web Worker. No install, no account friction.
Submit
Write a JS function or upload WASM and submit it at /jobs. The orchestrator splits the work into tasks and dispatches them across available nodes.
Compute
Tasks run in parallel across browsers and results aggregate automatically. Watch the grid live at /dashboard and track usage at /billing.
Simple marketplace pricing
Pay-as-you-go for what you use. Withdraw what you earn. No subscriptions.
Distribute your workload across the grid and pay only for the compute you consume, billed from prepaid credits.
Leave a tab open and earn for every task your machine completes. Close it any time — no commitment.
A core-hour is one hour of task wall-time multiplied by the node's CPU cores.
Built for untrusted code
Every task is treated as hostile. The boundary is hardened and proven live.
Hardened worker realm
Trust at the orchestrator
Beyond CPU and RAM
CloudXaaS is not limited to CPU and RAM. With navigator.gpu kept intact inside the sandbox, WebGPU compute is on the roadmap — bringing GPU workloads to the same browser-native grid.
