Brand
A terminal window manager that knows what your agents are doing.
tuios is a terminal window manager. It opens panes, tiles them and keeps nine workspaces inside the terminal you already use. A daemon keeps sessions running when you detach, and the panes that run a coding agent show whether it is working, idle or waiting for you. This page has the logo, the mascot and the colours, and the files to use when you write about it.
Mascot
Tilly
Tilly is a small CRT monitor whose screen face is a tiled window layout: two panes on top are the eyes, a wide pane below holds a >_ prompt for a mouth, and the focused pane has a blue border. Tilly guides the Learn tour and stands for tuios wherever a friendly face fits better than a logo.
Pick a mood below.
Using Tilly
- Use Tilly for friendly, informal places: a talk slide, a sticker, a blog post header, a tutorial.
- Pick the mood that fits the moment. Idle is the default.
- Tilly keeps the same colours on dark and light backgrounds.
- Do not redraw Tilly, change the colours, or give Tilly new clothes, props or words in a speech bubble that the project did not write.
- Do not put Tilly next to another project's logo as if tuios endorsed it.
Meet Tilly in the Learn tour. Turn the 3D Tilly around by dragging it, pick a mood under it, or click any Tilly on this page to play a move.

Logo
Mark, wordmark and lockups
The mark is Tilly. The wordmark is tuios in lowercase, set in Fredoka SemiBold. The lockups put the two together. Every file comes in a version for dark backgrounds and one for light.
Clear space
Keep a margin around the logo of at least one quarter of the mark's height, marked x. The lockup files already include it, so place them edge to edge with other content.
Minimum size
Below 48 px the full body gets too small to read, so each size has its own drawing. Use the one made for the size you need.

Type
Fonts
One face for the wordmark and two for this site. All of them are free to use.
Fredoka SemiBold
The wordmark, and the titles on social cards
The wordmark files are outlines, so you do not need the font to use them. Use Fredoka for a title that sits next to the logo.
Monaspace Neon
Headings, navigation, code and keys on this site
A monospace face by GitHub Next. It ties the site to the terminal.
System sans-serif
Running text on this site
Long text reads faster in the sans-serif face of the reader's device, so the site ships no font for it.
The reader's own system font

Terms
Using the logo and Tilly
The tuios source code is MIT licensed. The name, the logo and Tilly are how people recognise the project, so they come with a few plain rules of their own.
You may
- Use the logo, the wordmark and Tilly to link to tuios, or to write, talk or teach about it: in articles, videos, slides, package listings, and pages for tools that work with tuios.
- Use the files as they are, no smaller than the minimum sizes on the brand page.
Not allowed
- Do not alter the mark: no new colours, stretching, redrawing, outlines, effects or added parts.
- Do not imply that tuios or its maintainer endorses, sponsors or made your product.
- Do not use the logo or Tilly as part of your own product's name, logo or icon.
Ask before any commercial use of Tilly, such as stickers or merchandise for sale, or Tilly in the marketing of a paid product. Open an issue on GitHub to ask.
The wordmark is set in Fredoka and converted to outlines, so the files need no font. Fredoka is under the SIL Open Font License 1.1.
