Workflow DevKit is in beta
use workflow brings durability, reliability, and observability to async JavaScript. Build apps and AI Agents that can suspend, resume, and maintain state with ease.
Reliability-as-code
Move from hand-rolled queues and custom retries to durable, resumable code with simple directives.
export async function welcome(userId: string) {
"use workflow";
const user = await getUser(userId);
const { subject, body } = await generateEmail({
name: user.name, plan: user.plan
});
const { status } = await sendEmail({
to: user.email,
subject,
body,
});
return { status, subject, body };
}Queueing the getUser step...
Effortless setup
With a simple declarative API to define and use your workflows.
Observability. Inspect every run end‑to‑end. Pause, replay, and time‑travel through steps with traces, logs, and metrics automatically.
Universally compatible. Works with the frameworks you already use with more coming soon.
Reliability, minus the plumbing
Start with plain async code. No queues to wire, no schedulers to tune, no YAML. Best‑in‑class DX that compiles reliability into your app with zero config.
See every step, instantly
Inspect every run end‑to‑end. Pause, replay, and time‑travel through steps with traces, logs, and metrics automatically captured — no extra services or setup.
A versatile paradigm
Workflows can power a wide array of apps, from streaming realtime agents, to CI/CD pipelines, or multi day email subscriptions workflows.
Build anything with
Build reliable, long-running processes with automatic retries, state persistence, and observability built in.
export async function aiAgentWorkflow(query: string) {
"use workflow";
// Step 1: Generate initial response
const response = await generateResponse(query);
// Step 2: Research and validate
const facts = await researchFacts(response);
// Step 3: Refine with fact-checking
const refined = await refineWithFacts(response, facts);
return { response: refined, sources: facts };
