Things people build with this

USE CASE 1

Build payment processing pipelines that complete reliably even if servers crash mid-transaction.

USE CASE 2

Orchestrate multi-step order fulfillment workflows across multiple microservices without losing progress.

USE CASE 3

Run scheduled data migration jobs that can pause and resume without manual intervention.

USE CASE 4

Manage subscription billing cycles that must execute on time and retry failed charges automatically.

Getting it running

Difficulty · hard Time to first run · 1day+

Requires running multiple services (gRPC server, worker processes, state persistence) and understanding distributed workflow concepts to see meaningful results.

Temporal is open-source under the Temporal Community License and Server Side Public License (SSPL), allowing free use for most purposes but with restrictions on offering it as a managed service.

In plain English

Temporal is a platform for running "durable" application logic, meaning it can execute long-running processes that survive crashes, server restarts, network failures, and other intermittent problems without losing their place. The core idea is that code written as a Temporal Workflow will automatically retry failed steps and resume from where it left off, even if the underlying servers go down and come back up. Developers write normal code, and Temporal handles all the complexity of making it resilient. This is particularly valuable in microservices environments, systems where many small services communicate with each other and failures are common. Temporal acts as an orchestrator, coordinating the sequence of operations across services and ensuring each step completes. It also supports scheduled jobs (cron-style tasks) and can manage millions of concurrent workflows. The platform originated as a fork of Uber's Cadence system, developed by the same creators. The server itself is written in Go, but developers write their application workflows in the language of their choice, Go, Java, Python, TypeScript, and others are officially supported via separate SDK libraries. You would use Temporal when building backend processes that must be reliable even in the face of infrastructure failures: payment processing pipelines, order fulfillment flows, data migration jobs, subscription billing cycles, or any multi-step business process that could take minutes or days. Getting started locally is straightforward, install the Temporal CLI with Homebrew and run a single command to start a development server, then open a web UI at localhost to monitor your workflows.
