Why GTmeta?

⚙

Metadata-Driven

Define pages, grids, forms and business logic as metadata. The engine renders everything dynamically.

★

AI-Powered

Built-in Claude AI integration for intelligent form assistance and data analysis.

⚖

Enterprise Ready

Role-based access, multi-project, multi-database, scheduler, mail merge and more.

⚛

Modern Stack

Angular, Angular Material, Ionic, AG Grid, Node.js, MongoDB: all open source.

Learn by Building

A hands-on training path: turn empty pages into working ones, metadata only. Guided exercises, a Designer guide, preloaded SQL and a playground project. Everything is included with GTmeta.

✎

Guided exercises

From the first CRUD table onward, on a real project with its data already in place. The statements are written for you: what you learn is the wiring.

⚙

The Designer guide

The workbench and its power tools: what each button does, and how much of the page it writes for you once you know what the page needs.

▢

A playground project

The project you explore in the online demo is the same one you learn on. It ships with GTmeta, data included: nothing to set up.

The long way to understand, the fast way to deliver.
