Playground FAQ

Is this a live execution?

No. Each demo is a deterministic replay of a real run recorded on our own Heym instance. Every step, output, and timing is genuine. We replay recordings so the playground stays instant, free, and abuse-proof.

Do I need an account to use the playground?

No. There is no signup, no trial, and no sales call. Pick a demo, press Run, and inspect every node.

Can I run these workflows myself?

Yes. Copy or download the workflow JSON from any demo and paste it onto your self-hosted Heym canvas. Add your own credentials and the same flow runs live on your machine.

Why replays instead of live runs?

Live anonymous browser automation and LLM calls would need rate limits, queues, and security sandboxes, and those make demos slow and flaky. Recorded replays keep the data real and the experience instant.

Don’t have Heym yet?

Heym is Self Hosted and Source Available, clone it and spin up the canvas locally in under a minute, then run the workflows you just watched.

$ git clone https://github.com/heymrun/heym.git
