Playground

See how facts become answers. Pick a domain, try a change, and watch a real Triplex database update in your browser. No installation or JSON editing needed to get started.

What this demonstrates

The sample query runs automatically. Add a score or a training record to change its answer, then use Retract this change to see the original result return. Retraction changes which facts are currently visible; the journal keeps both writes. Reset database starts a fresh session, including a fresh journal.

Open Go further: edit queries and transactions to experiment with the underlying JSON. The guided actions populate the transaction editor, so you can inspect the exact assertion or retraction you just ran. Raw entity facts include IDs you can use in your own retractions.

The playground keeps one ManagedRuntime alive while you interact with a domain, so every command resolves the same Triples service and in-memory KV store. Switching domains or resetting disposes that runtime and builds a new one. This is the browser equivalent of the layer-lifetime guidance in Getting started.

The query and transaction editors decode the same public DatalogQuery and TransactRequest schemas used by Triplex hosts and the CLI. Results are bounded to 100 rows. For durable data, graph constraints, configuration authoring, or a larger operator interface, continue to CLI and dashboard.
