An “H” for HostPane, with a window pane for its crossbar — the panel you look through to run a server. Here is every version, how to use it, and the files.
Two versions of one logo. Pick the one that contrasts with what is behind it: the light version (navy tile) on white and light backgrounds, the dark version (white tile) on navy, black and dark photos. The orange pane stays orange in both.

Dark version · on navy, black and dark photos
Lockups
The horizontal logo is the default. Use the stacked logo where the space is closer to square, and the mark alone where the name is already on screen — app icons, avatars, the browser tab.

One colour
For print, stamps, embroidery, engraving — anywhere only one ink is allowed. The bars and pane are cut out of the tile, so whatever is behind the logo shows through them.

Clear space & minimum size
½ tile½ tile
Keep clear space on every side of at least half the tile's width. Nothing — text, edges, other logos — goes inside it.
32 px · smallest logo
32 px · smallest mark
below 32 px · small variant
Don't show the logo or the mark smaller than 32 px tall. Below that use the small favicon variant: heavier bars and no window lines, so it stays an “H” at 16 px.
Colours
Three colours make the logo. On the website, navy is the ink and orange is the accent — used for calls to action and highlights, never as a background for long text.
Navy#0F172ARGB 15 23 42Tile (light version), letter (dark version), text
Orange#F97316RGB 249 115 22The window pane — orange in every colour version
Text on orange. White on #F97316 is only 2.8 : 1, below the 4.5 : 1 that body text needs. Put navy text on orange (6.4 : 1), or use the darker #C2410C when the text must be white (5.2 : 1). The same #C2410C is the colour for orange links and labels on white.
