Comparison

Mobius vs Temporal — an honest comparison.

Both run durable workflows. The question is what you're building, who's running it, and how much platform team you have.

TL;DR

Side-by-side.

Both platforms give you durable workflows. The differences below are the ones we hear about most.

Temporal
Mobius
Primary focus
Durable execution for engineering teams
Durable execution + human-agent coordination
Time to first workflow
Weeks (cluster setup or Cloud onboarding)
Minutes
Human↔agent interactions as steps
Build it yourself (signals, custom UI)
First-class step type
Agent-as-author SDK
Build it yourself
First-class — same API as humans
Worker placement
SDK embedded in your service
Pull-based, runs anywhere
Infra ops burden
High self-host, or Temporal Cloud
Fully managed; self-host available
Entry pricing
$200+/mo on Temporal Cloud
$20/mo (early access)

Choose Temporal if…

  • You're operating at Uber/Netflix scale and have a dedicated platform team to run a Temporal cluster.
  • Your workflows are pure code orchestration — no humans in the loop, no AI agents authoring work.
  • You've already invested heavily in the Temporal SDK ecosystem and the cost of switching outweighs the benefits.
  • You need the deep enterprise SLAs Temporal Cloud offers and the budget to match.

Choose Mobius if…

  • You're building products where AI agents and humans need to coordinate as peers — not just engineers running deterministic backends.
  • You want first-class human-in-the-loop without standing up a separate approval system.
  • You don't have a platform team to run workflow infrastructure, and you'd rather not build one.
  • You're shipping AI-forward products and need agent SDKs as a first-class surface, not an afterthought.
The jobs you're hiring for

What workflow platform are you actually hiring?

Three jobs Mobius is built for that Temporal isn't natively shaped around.

01

Coordinate AI agents with durable, audited human checkpoints.

Agents draft, humans approve, agents continue — durable across days, with one audit trail. Mobius's interaction step is the primitive; on Temporal, you build it from signals + custom UI.

02

Add human↔agent interactions as first-class workflow steps.

Both directions: agent waits on human, human waits on agent. One line of definition, native UI, native audit. Not a separate approval app you wire up.

03

Build fleets of agents that coordinate themselves.

Agents call the same workflows API humans use. They trigger work, hand off, escalate. Mobius treats agents as first-class actors; Temporal treats them as workloads inside an activity.

Conceptual mapping

If you know Temporal, you'll find these familiar.

The concepts overlap heavily. Where Mobius adds primitives, it's because the Triad demands them.

Temporal
Mobius
Workflow
Workflow
Activity
Step (with an action)
Signal
Signal — also delivered when an interaction completes
Worker (SDK-embedded)
Worker (pull-based, claims jobs)
Task queue
Queue (workers subscribe by name)
Schedule
Schedule trigger
(no native equivalent)
Interaction step — wait on a user, agent, or group
Three differentiators

What you don't get on a pure durable-execution platform.

The Triad as a primitive.

Humans, agents, and systems are equal participants in the same workflow. Not a runbook, not an approval bolted on top — the workflow definition itself.

Interactions are bidirectional.

Agents and humans wait on each other as first-class workflow steps. Three types — approval, review, input — and any target — user, agent, group.

Workers run on your infra.

Pull-based workers authenticate to Mobius and execute locally. Mobius coordinates without executing your code. Your secrets and data never leave your environment.
