Capabilities
Make the workspace yours.
A theme engine with presets, fully custom themes, and background images. You stare at this workspace all day, sometimes all night while the fleet runs. It should look the way you want.
The theme engine
Three ways to set the mood.
Presets
Ready-made themes you can switch between in seconds. Pick one and the whole workspace follows, terminals and editor and panels together, no fiddling required.
Custom themes
Build a theme of your own when no preset fits, and make it the look you work in every day. The custom themes guide covers creating and validating one from scratch.
Background images
Bring an image into the workspace and work on top of it. A small thing, but it is often the difference between a tool you use and a tool that feels like it belongs to you.
Reach
One look, the whole workspace.
The terminal
Loom's terminal is WebGL with true color support, so themes render exactly as designed across all six fleet sessions, every tab, and every split.
The editor
The CodeMirror 6 editor shares the same look, so reading a diff and reading your own code feel like the same place.
The panels
File explorer, source control, web preview, markdown preview: the parts of the workspace you live in wear the theme together, not a patchwork of defaults.
Questions
Themes, answered.
Can I create my own theme?
Yes. The theme engine supports fully custom themes alongside the presets. The custom themes guide walks through creating and validating one.
Can I use a background image?
Yes. Background images are part of the theme engine, alongside presets and custom themes, so the picture you work on top of is as much a choice as the colors are.
Why do themes matter in an agent app?
Because Loom is not a dashboard you glance at. It is a full workspace with a terminal, an editor, source control, and previews, and missions can run for hours. A workspace you like looking at is one you keep open.
Does any of this cost extra?
No. Loom is free and open source under Apache-2.0, themes included. The only thing you ever pay for is your model providers, directly. See pricing.
