Concepts

Why Flux is built the way it is — the design decisions, tradeoffs, and mental models behind durable execution and agents.

Concepts is where you find out why Flux is built the way it is. The other tabs show you how to use it; this one is the engineering case.

Foundations covers the argument for durable execution and the model Flux uses for it: events, checkpoints, replay, and what makes a workflow deterministic. Start with Why durable execution.

Architecture is the system view: server, workers, storage, and how a workflow run actually flows through them. Start with System architecture.

Agents explains how Flux models agents as durable workflows, how memory is structured, and the sub-agent tree pattern. Start with Agents as durable workflows.

Compared to alternatives is the honest assessment of Flux next to Temporal, Prefect, Dagster, the agent frameworks, and plain queues. Start with vs. Temporal.
