Mycel vs Temporal
A durable execution engine, and a harness for AI work, are different layers.
What Temporal is good at
Temporal provides durable execution for workflows you write. It is useful when your engineering team needs long-running processes, retries, and recovery across interruptions. Your application still needs to handle external side effects and their idempotency.
The actual difference
Temporal is infrastructure for an application you build. Mycel is software a service firm configures around client jobs, files, methods, and delivery. They are different layers, not substitutes for the same engineering requirement. Evaluate Mycel's documented controls rather than treating a product interface as proof of safety. Delivery follows your authorized rules. Automatic delivery is on by default for eligible work that passes its checks; turn it off or require review for an engagement. Checks do not guarantee correctness.
Side by side
| Temporal | Mycel | |
|---|---|---|
| Layer | Durable execution for your application | Client-work software for a service firm |
| Review controls | Design in your application | Automatic delivery for eligible work, or required review |
| Credentials | Your application's controls | Review the documented connection controls |
| Execution environment | Your workers and infrastructure | Managed work execution within product limits |
| Recovery | Workflow history and retry policies | Saved jobs and their work history |
| Setup | Integrate and operate workflows | Configure client work in the hosted product |
Choose Temporal
- The workflows are deterministic code, not model calls
- You need durable orchestration and will design safe retries for external actions
- You already run it and the AI part is a small piece of a larger process
Choose Mycel
- You want existing client-work software with configurable delivery controls
- You prefer to configure supported connections rather than build their handling
- You want a service business, not a workflow engine to build one with
