Query playground (EQL-S)

Interactive fixture graph run canned EQL-S-style queries and highlight matches.

Trellis exposes the workspace as a queryable graph (EQL-S, compiled to Datalog). The full engine runs in the CLI and Studio; this page uses a small fixture so you can see matches light up without a local repo.
