vendor: Cloudflare

whatItIs: Agent-focused runtime where each agent gets a 'computer' with a durable filesystem (SQLite-backed), plus execution backends that dynamically orchestrate between fast V8 isolates and full Linux containers.
hosting: managed-only
pricingModel: per-second + Workers pricing
sandboxRuntime: V8 isolate + container hybrid
modelProviders: multi-model
stateModel: durable filesystem
toolModel: shell + filesystem + git
includesBrowser: false
includesMemory: false
longRunning: unbounded
hitlSupport: false
observability: built-in traces
maturity: preview
launched: 2026-08-03
notes: Announced at Cloudflare Agents Week Aug 2026. Three execution backends: isolate-shell, container, and isolate-JavaScript (ECMAScript modules in Dynamic Workers). Designed so containers are needed for less than 10% of an agent's work. Competes with E2B, Daytona, Modal Sandboxes. Open-source.
