Pre-alpha. First usable release planned for late 2026.

Gramlot Rosetta · Online learning lab

The same idea.
Five implementations.

Rosetta helps you understand how Gramlot works by comparing small, running examples in Gramlot Python, Gramlot JavaScript, React, Vue and NiceGUI.

You see the interface alongside the source that creates it. No installation is needed to explore the hosted lab.

Rosetta’s Hello World lesson: framework tabs above a running example and its actual source.
A real lesson in Rosetta. Use the framework tabs to compare the implementations.

Your first visit

  1. Choose Hello World under Simple examples. Start with a single heading before moving on to input widgets and data binding.
  2. Switch framework tabs. Compare the same behavior and read the source beside the result. Overview explains each version’s reusable setup separately.
  3. Try Gramlot JS. Edit the recipe and press Run. Reset brings back the original; reloading discards your edits.

A learning tool in pre-alpha.

Rosetta illustrates different ways to write the same interface. It is not a performance benchmark. Source in the other implementations is read-only, and browser edits are not saved to files.

The visual builder is a separate experiment available in the lab. Read what the visual editor can do today.
