Cloudflare Dynamic Workflows: MIT-Licensed Durable Execution That Gives Each AI Agent Its Own Stateful Workflow at Near-Zero Idle Cost

Cloudflare Blog·medium signal

Cloudflare shipped Dynamic Workflows in May 2026, an MIT-licensed library extending its durable execution engine so workflow code can differ per tenant, agent, or request at runtime. Built on Dynamic Workers (V8 isolates that boot in milliseconds, 100x faster than containers), it enables platforms to serve millions of unique durable workflows. Each agent gets persistent state via Durable Object Facets — its own SQLite database. This solves the 'one-size-fits-all workflow' problem: per-agent durable state with the isolation guarantees of V8 sandboxing.
