Workflow engine

Pipelinesyoucansee,replayandtrust.

plainhand workflows are graphs, not scripts. Compose triggers, planners, tools and verifiers visually — then run them at scale with full traces, deterministic replays and one-click rollbacks.

Step 1

Trigger

Webhook, schedule, queue or human handoff. Anything that fires an event.

Step 2

Plan

An agent breaks the goal into typed sub-tasks with budgets and constraints.

Step 3

Route

Each sub-task is dispatched to the optimal model, tool or sub-agent.

Step 4

Execute

Tools run in sandboxes; results stream back with structured traces.

Step 5

Verify

Guardrails, evals and policies score every output before release.

Step 6

Deliver

Results are returned, cached, and observable end-to-end.

Live runs

Every run, replayable.
