One goal. A real graph.
A planner proposes the work. The engine validates dependencies and starts each step as soon as its inputs are ready.
Connecting
An orchestration engine, built from scratch
Give every agent
a place in the plan.
Turn a goal into connected steps. Run independent work in parallel. Keep every result, even when a worker stops.
No key needed for the demo. Bring your own key for real model runs.
Dependency schedulerIllustration
Independent branches run together. Each completed result is saved before dependent work can use it.
Dependency-aware schedulingPostgres checkpointsWorker crash recoveryPer-step traces
A workflow you can actually follow.
See the inputs, decisions and failures behind the final answer.
Failures have a next step.
Retry temporary errors, repair a failed branch, or resume from the last saved result after a worker disappears.
Nothing hidden in the answer.
Inspect resolved prompts, attempts, sources, tokens and estimated costs. Export the report and execution trace.
Start with a working pattern.
Six editable workflows, from your first parallel run to a failure-recovery experiment.
How Relay orchestrates
Watch three independent analyses meet at one synthesis step.
Dependency readiness and parallel executionUse templateResearch a technical decision
Investigate options and risks in parallel, review the evidence, then write a recommendation.
Parallel research, review and synthesisUse templateDesign an agent platform
Compare infrastructure and failure policies before writing an architecture decision.
Fan-out analysis with a decision recordUse templateTurn JSON into a brief
Validate a typed extraction and reference individual fields in the next prompt.
JSON Schema validation and field templatesUse templatePlan a developer launch
Develop the audience, quality gate and launch message as independent workstreams.
Independent branches and a shared final artifactUse templateRecover from an API failure
Inject one simulated overload. Watch the failed attempt retry while the other branch continues.

The agents do the work.
Pi, Claude Code and Codex each bring their own model and tool loop. Relay provides the dependencies, checkpoints and failure policy around them.
