Comparison

Mobius vs Inngest — an honest comparison.

Both run durable workflows for AI builders. The shape of the platform differs: where humans and agents fit, and how code gets invoked.

TL;DR

Side-by-side.

Both platforms give you durable execution. Mobius adds the Triad — humans and agents as first-class participants in the workflow itself, not orchestrated as workloads inside it.

Inngest
Mobius
Primary focus
Durable execution for any code (incl. AI workflows)
Durable execution + human-agent coordination
Execution model
Push: Inngest invokes your functions over HTTPS
Pull: workers claim jobs from queues
Human↔agent interactions as steps
Composed via step.waitForEvent + custom UI
First-class step type with built-in UI and audit
Agents
AgentKit — TypeScript library on top of the platform
Agents are first-class users of the same workflow API
SDK languages
TypeScript, Python, Go
Go, Python, TypeScript (equals)
Workflow definition
Code-first (TS / Py / Go)
Code or YAML (the same shape)

Choose Inngest if…

  • You want push-based, serverless-friendly orchestration: Inngest invokes your functions, you don’t run a worker fleet.
  • Your workflows are code-first and you’re happy expressing them in TypeScript, Python, or Go.
  • AgentKit’s opinionated agent shape (tool loops, sub-agents, MCP tools) matches what you’re building.
  • You’re comfortable composing human-in-the-loop yourself with waitForEvent and a custom UI.

Choose Mobius if…

  • Human↔agent interactions are central to your product — and you want a first-class step type, not glue.
  • You need workers on your infra without exposing inbound HTTPS — pull-based claiming fits.
  • You want agents to be users of the workflow API: same primitives humans use, same audit trail.
  • You want declarative workflow definitions you can edit (and review) without redeploying code.
The jobs you're hiring for

What workflow platform are you actually hiring?

Three jobs Mobius is shaped around that aren't Inngest's default frame.

01

Make human approval a first-class workflow step.

Approvals, reviews, and free-form input as a single step type with native UI and durable audit — not waitForEvent + a side app to capture the response.

02

Treat agents as users of the workflow API.

Agents authenticate, trigger workflows, hand off to other agents, and wait on humans through the same SDK. Not a separate library on top — the platform's primitives are the agent surface.

03

Run workers wherever your code does — pull-based.

Workers claim jobs over HTTPS without exposing inbound endpoints. Useful when your workloads handle sensitive data or run inside networks that don't accept inbound invocations.

Conceptual mapping

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

Most concepts overlap. The differences are exactly where the Triad shows up.

Inngest
Mobius
Function
Workflow
Step (within a function)
Step (within a workflow)
Event trigger
Webhook trigger
Cron trigger
Schedule trigger
step.sleep / step.sleepUntil
sleep step
step.waitForEvent
Signal — also delivered when an interaction completes
AgentKit (TypeScript library)
Agents as users of the workflow API directly
(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 workflow itself — not workloads orchestrated by it. The architectural unit is the Triad, not the function.

Interactions are first-class.

Three types — approval, review, input — and any target — user, agent, group. Native UI, native audit, one line of definition. Not waitForEvent plus a side app.

Pull-based workers.

Workers claim jobs from queues over outbound HTTPS. No inbound exposure required. Useful for sensitive workloads, regulated environments, or networks that don't accept inbound invocations.
