Welcome to Temporal

What if your code was crash-proof?

Failures happen. Temporal makes them irrelevant. Build applications that never lose state, even when everything else fails.

@workflow.defn
class SleepForDaysWorkflow:
    # Send an email every 30 days, for the year
    @workflow.run
    async def run(self) -> None:
        for i in range(12):
            # Activities have built-in support for timeouts and retries!
            await workflow.execute_activity(
                send_email,
                start_to_close_timeout=timedelta(seconds=10),
            )

            # Sleep for 30 days (yes, really)!
            await workflow.sleep(timedelta(days=30))
        

Write code as if failure doesn’t exist

Distributed systems break, APIs fail, networks flake, and services crash. That’s not your problem anymore. Managing reliability shouldn’t mean constant firefighting.

Temporal Workflows automatically capture state at every step, and in the event of failure, can pick up exactly where they left off.

No lost progress, no orphaned processes, and no manual recovery required.

You have to see it to believe it

Temporal doesn’t work like anything you’ve used before. Watch how we guarantee the Durable Execution of your code in the face of any failure.

How It Works

Create failproof apps using our SDKs

Write your business logic in the programming languages you already use with our native SDKs. Your days of writing reconciliation logic or boilerplate code are over.

Build Workflows that handle failures for you

Write your business logic as code as a Temporal Workflow. Workflows might involve moving money between bank accounts, processing orders, deploying cloud infrastructure, training an AI model, or something else entirely.

Because the full running state of a Workflow is durable and fault tolerant by default, your business logic can be recovered, replayed, or paused at any point.

Write Activities to handle and retry failure-prone logic

APIs fail, networks time out, and users abandon sessions.

Temporal treats these interactions as Activities: functions that retry automatically and recover seamlessly.

Replace your brittle state machines

The Temporal Service persists the state of your application and has built-in retries, task queues, signals, and timers, to make sure your code always picks up where it left off.

Host the Temporal Service yourself as part of the open-source project, or let us host it for you with Temporal Cloud.

Get full visibility into your running code

No more wasting time sifting through logs. Get visibility into the exact state of each of your Workflow executions.

Common patterns and use cases

Artificial Intelligence & Large Language Models

From model training to data prep, Temporal keeps your AI workflows resilient and repeatable.

Humans-in-the-Loop

No more duct-taping Workflows around human input: just clean, durable orchestration.

Compensating Patterns (Saga)

Make Saga easy: what if Saga was simply a try...catch?

Long-running Workflows

Run Workflows for days, weeks, or months without losing progress or adding complexity.

Order Fulfillment

One bad service shouldn’t break the cart. Temporal keeps the order moving.

Durable Ledgers

Track transactions with code you can trust down to the last cent.

CI/CD

Deploy with confidence. Temporal gives you clean retries, rollbacks, and visibility.

Customer Acquisition

Route leads, onboard users, and engage customers without dropped steps or hacks.

DAG

Don’t glue together DAGs with bash and hope. Temporal does it right.

One of the most interesting pieces of tech I've seen in years… Temporal does to backend and infra, what React did to frontend… the surface exposed to the developer is a beautiful "render()" function to organize your backend workflows.

Guillermo Rauch

Founder & CEO, Vercel

Temporal's technology satisfied all of these requirements out of the box and allowed our developers to focus on business logic.

Without Temporal's technology, we would've spent a significant amount of time rebuilding Temporal and would've very likely done a worse job.

Fully battle tested, 9 years in production

Temporal was built with over 20 years of development from the minds behind AWS SQS, AWS SWF, Azure Durable functions, and the Cadence project that powers Uber.

Deploy it your way

One platform, two great hosting paths

Temporal is an open-source project that you are free to use and host in your own environment. You can also let us host the Temporal Service for you with Temporal Cloud. Either way, we never see your code.

Build invincible applications

It sounds like magic, we promise it not.
