Demos

Each demo runs on this server, on lith. Open one in two windows to see the other's changes arrive.

  • Guestbook

    Sign the book: the entry reaches every open tab in the next tick, and only your tab hears if it was refused.

  • Writer race

    Up to 200 producers send commands to one writer for three seconds, and everyone watching sees the batches grow, tick by tick.

  • Stream inspector

    Your own stream, live: what the hub sends this tab, what zstd makes of it, and what the memory budget gave its encoder.

  • Canvas

    Paint on one pixel canvas with everyone here: each stroke is a command, and one render a tick carries the board to every painter.

  • Shared board

    Drag a card to another lane: the board renders once in the next tick, and every open tab sees it glide there.

  • Cursor party

    Every visitor's pointer, live: each tab sends its position 15 times a second, and one view draws them all once per tick.

  • A million checkboxes

    One grid of a million boxes for everyone: tick one, and every tab that has it in view sees it flip within a tick.

  • Game of Life

    One board for everyone: the server computes ten generations a second while anyone watches, and every tab gets the same frame.
