Tools

Build, check, and ship OGraf packages.

A growing set of browser-based tools for everyone writing OGraf graphics. Everything runs client-side — no sign-up, no upload.

Package Checker

New

Validate a .zip before you ship.

Drop any OGraf package and get a structured report against 82 rules across manifest, data schema (GDD), structure, module, styling, assets and runtime. Validates against the official EBU schema — live, with a pinned offline snapshot as fallback. Runs entirely in your browser — no upload.

Runtime Harness

Load your package and drive the lifecycle.

Mount a package in a sandboxed iframe and call load / playAction / updateAction / stopAction / customAction / dispose for real — plus goToTime and setActionsSchedule when the manifest declares non-real-time support. Captures timings, return values, console output and a live preview, and adds 14 runtime checks to the report. Built into the Package Checker.

Schema Explorer

Browse the OGraf manifest schema in plain language.

Every top-level field of an .ograf.json manifest, grouped into five designer-friendly clusters, plus a visual catalogue of every operator-input type. Sourced live from the EBU schema with a bundled fallback.

Template Generator

Coming soon

Scaffold a new OGraf package from a preset.

Pick a base (lower third, bug, ticker, …), tweak a handful of fields, and download a ready-to-edit package with manifest, module, stylesheet, and local fonts already wired up correctly.
