Temporal
Temporal is an open-source durable execution platform, originating from the Cadence project. It orchestrates long-running workflows and individual activities resiliently, with automatic retries, durable state and support for multiple programming languages.
Temporal is an open-source platform for durable processes: workflows and activities survive outages, retry automatically and keep their state. It is powerful, but demanding to self-host.
Explanation
Temporal separates process logic from work steps: the workflow describes what should happen in which order, the activity performs the individual step — model call, database access, mail delivery. The workflow's state is fully recorded, so a run resumes exactly after a crash, a restart or days of waiting. For agentic systems that is a solid backbone, especially with several languages in play. The price is operational effort: the service belongs behind the firewall like a database, and scaling, visibility storage, encryption of sensitive payloads and upgrades are all work. If you cannot carry that, use the hosted service; if you need data sovereignty, self-host in your own EU infrastructure.
Marketing Relevance
For companies with their own operations teams, Temporal is the option where execution and data stay entirely in-house — a strong argument in regulated settings. For smaller teams the same fact is the hurdle: running it costs more than the agent logic on top.
Example
An onboarding process reviews documents, obtains an internal approval, creates accounts and notifies the customer. The workflow waits days for approval if needed and runs each sub-step with its own retry policy.
Common Pitfalls
The biggest mistake is underestimating operations: the service must never be publicly reachable, and some scaling parameters can only be changed later through migration. Where sensitive data flows through workflows, payload encryption is additionally required.
Origin & History
Temporal emerged in 2019 as a fork of Cadence, developed at Uber for long-running processes. The platform is MIT-licensed and developed further by Temporal Technologies; a hosted service exists alongside. With multi-step agents from 2024 it gained additional importance as an execution foundation.
Marketing Use Cases
Long-running business processes with approvals and deadlines.
Agent runs spanning hours or days.
Reliable data migrations and imports.
Processes spanning several programming languages.
Frequently Asked Questions
Can Temporal be operated in the EU?
Yes, self-hosted entirely in your own EU infrastructure — the usual route when data sovereignty is required. For the hosted service, settle the region contractually.
Do I need Temporal for a simple agent?
No. For short runs a library with a loop cap suffices. Temporal pays off once runs take long, wait for approvals or need many steps to be reliably repeatable.
Does Temporal measure the quality of my agents?
No. It secures execution. Model quality needs tracing and evaluations, for instance via an observability platform for language models.
