Node-based

In Unix, everything is a file. In SkyAlt, everything is a node.

• Node can be GUIs(button, slider, map, calendar, etc.) or programs(LLM, SQLite, Python, etc.).
• Nodes are composed into graphs.
• Graph can be put into other graphs.

LLM-powered

SkyAlt is not about AI research, but interface research and development. LLM is the new programming paradigm that can make human-computer interactions way more efficient, natural and frictionless. Building an app means only 2 things:

• Put GUIs on layout
• Write a list of features in natural language

Local-first

Most of today's apps run in a browser as Software as a Service. Here's the list of problems you may experience:

• delay between client and server
• none or simple export
• hard to migrate between clouds
• data disappear(music playlist, etc.)
• data was tampered
• new SaaS version was released and you wanna keep using the older one
• no offline mode
• SaaS shut down
• price goes up
• 3rd party can access your data

SkyAlt solves them with Local-first computing. The biggest advantages can be summarized as:

• quick responses
• works offline
• ownership
• privacy
• works 'forever' + run any version

For endurance, SkyAlt uses only well-known and open formats SQLite and JSON.
