In a November 14, 2026 announcement, Theo said users can ask an agent to customize T3 Code’s interface inside the app, with changes updating “on the fly.” The catch: he clarified that the feature was available only in nightly builds, not stable. Source Source
Theo said it would reach stable “soon,” but supplied no release date. Source
T3 Clawd brings a Claude-inspired makeover
User rohit3a introduced T3 Clawd, saying he had substantially reworked T3 Code’s interface using its new theming features. He said he liked T3 Code’s functionality but had kept returning to Claude Code because he preferred its UI. Source
The T3 Clawd repository describes a “Claude-inspired theme” built entirely on T3 Code’s theme system: “One theme file. No fork, no source changes.” Its README lists Claude-style colors and typography, a header renamed “T3 Clawd,” a live timer replacing the “Working” spinner, and a one-column model picker. Apparently, even the model picker has to match the outfit. Source
The README’s installation instructions are to download t3-clawd.json, open Settings → Appearance, select Add a theme, and import the file or paste its contents into Theme JSON. It says both dark and light modes are included. Source The theme and installation instructions have not been independently tested for this article.
The author says T3 Clawd was built on T3 Code Nightly in November 2026 and styles the app through internal attributes, so an update “may break a piece or two.” The theme is also unofficial and unaffiliated with Anthropic or T3. No fork doesn’t mean no upkeep. Source
The fork story is a different route
Theo separately described a nontechnical friend who saw the announcement and asked her agent to customize her installation—but she was running stable. According to his account, the agent cloned the source, leaving her on a fork of T3 Code. That’s a different route from T3 Clawd’s documented no-source-changes theme. Quite a detour for a UI request.
