Built by the community.
Runs in NextOS.

Apps, agents, skills, MCP servers, command-line tools, templates and skins that people outside the core team made for NextOS. Every entry has its own page, an install line and a link to its source. Anyone can add one.

Skins

A skin repaints the whole of NextOS from one small file. Open one and it goes on straight away.

  • CRTSkin

    A green phosphor terminal: scanlines, a soft bloom and a faint 60 Hz flicker over a black-on-green command line.

  • DawnSkin

    The twenty minutes before sunrise: deep indigo with peach and periwinkle drifting across it, generous spacing, and the strip up at the top.

Scripts

A script runs in NextOS’s sandboxed worker, bound to a command, an OS event or a schedule.

  • Hello scriptScript

    The smallest possible NextOS Script: one command that writes a friendly, timestamped note to your Notes folder.

Extensions

An extension contributes commands, panels and hooks into NextOS’s built-in apps and shell, activated lazily.

  • CSV toolsExtension

    A NextOS Extension that opens any .csv file as a sortable table, straight from a Finder context action.

    A complete chess app for NextOS with its own engine, opening book and game analysis - every rule, eight strengths, PGN files.

  • RecallApp

    Spaced-repetition flashcards whose decks are plain Markdown files you can edit anywhere, with an Anki-style scheduler and tools an agent can call.

  • SketchApp

    An infinite whiteboard for NextOS: shapes, arrows that stay attached when you move things, freehand, sticky notes, frames, and clean SVG export.
