What each says it does
rtxui

UISandbox
Test your design on the real thing: load a built web app, turn its knobs, verify 1:1, export.
How to run each
rtxui
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
UISandbox As a local MCP server: npm package
claude mcp add --transport stdio uisandbox -- npx -y uisandbox-mcpCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
The marketplaces of rtxui publish no settings it asks for, so we do not compare settings.
