Temporal Has a Free Workflow Engine — Build Reliable Distributed Systems Without Boilerplate

Temporal is an open-source workflow engine — write complex business logic as simple code, Temporal handles retries, timeouts, and failures.

What You Get for Free

• Durable execution — code survives process crashes
• Automatic retries — configurable retry policies
• Timeouts — activity, workflow, and schedule-to-start
• Signals — send data to running workflows
• Queries — inspect workflow state without stopping it
• Versioning — safely update running workflow code
• SDKs — Go, Java, TypeScript, Python, .NET, PHP
• Web UI — monitor and debug workflows
• Self-hosted — run on your infrastructure

Quick Start (TypeScript)

import { proxyActivities } from '@temporalio/workflow'

const { sendEmail, chargePayment, shipOrder } = proxyActivities({
  startToCloseTimeout: '30s',
  retry: { maximumAttempts: 5 },
})

export async function orderWorkflow(order: Order) {
  await chargePayment(order)     // retries automatically on failure
  await shipOrder(order)          // runs only if payment succeeded
  await sendEmail(order.email)    // guaranteed to execute
  // If the server crashes mid-workflow, Temporal resumes from last checkpoint
}

Why Developers Switch from Cron + Database Flags

Homegrown solutions use cron jobs and database flags for state:

• No lost work — workflow resumes after crashes
• Visibility — see every workflow's state in the web UI
• Complex flows — sagas, compensations, child workflows
• Testing — unit test workflows like regular functions

An e-commerce platform lost 2% of orders when their order processing server crashed between steps. After Temporal: 0% lost orders — every workflow resumes from exactly where it stopped.
