Try the live sandbox
A running Synapsys Core with real workers connected to it, so you can see what the console does before installing anything.
Open the sandbox console →Sign in with the username demo and the password demo.
What you are looking at
Four applications are connected, each built from its own example repository and each using the client library for its language:
| Worker | Library |
|---|---|
spring-boot-example | Spring Boot starter |
node-sdk-example | Node.js SDK |
python-sdk-example | Python SDK |
go-sdk-example | Go SDK |
Together they register more than eighty processes. None of them is a mock: they are ordinary applications that happen to declare their background work to Core. The same code is what the Get started guide walks you through.
What to try
Start something. Find invoice-poller on any worker and start it. Core does
not run the process — it records that you want it running, and the worker picks
that up on its next heartbeat, within about five seconds.
Watch its output. Open a run and read the log lines. That output is being
written by System.out or console.log inside the application and streamed to
Core against the specific run.
Stop something mid-flight. slow-stopper takes about fifteen seconds to
reach a safe stopping point, which makes the stopping state visible instead of
instantaneous.
Watch something fail. crashing-watchdog fails deliberately, ending in
failed rather than idle. Every third run survives.
Things worth knowing
It is shared and unauthenticated beyond the demo login. Anyone reading this page can start and stop the same processes you can. If something looks half-finished, someone else was probably here first.
It resets every night, which returns the workers and their processes to a known state.
It is a demonstration, not a service. Do not connect your own workers to it or put anything real into it.
Then run your own
The sandbox is one container plus four applications. To get the same thing locally, run Core and connect your first worker — the whole path takes about five minutes.
