It offers features like project management, plan/code mode switching, worktree support, and one-click commit/push. However, it has notable bugs including broken tilde path resolution, missing file diff views, and no security for its web server mode. Compared to alternatives like Verdant (praised for lightweight performance, parallel agents, and browser-like UX) and Gene, T3 Code brings little new to the table and needs significant work before daily use. ## Full article daily.dev links to this article rather than hosting it.

I don't know about the unusable part given that is what I have been using since last week. ## Similar posts on daily.dev - [A deep dive into T3 Code](https://daily.dev/posts/a-deep-dive-into-t3-code-6h6lkupwc) · Flavio Copes · 1 upvotes · 0 comments --- Tags: [#ai-coding](https://daily.dev/tags/ai-coding), [#claude-code](https://daily.dev/tags/claude-code), [#devtools](https://daily.dev/tags/devtools) [View this post on daily.dev](https://daily.dev/posts/t3-code-another-agentic-gui-that-is-good-but-not-usable--jorrdkvkz) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"T3 Code: Another Agentic GUI that is GOOD BUT NOT USABLE..","url":"https://daily.dev/posts/t3-code-another-agentic-gui-that-is-good-but-not-usable--jorrdkvkz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/t3-code-another-agentic-gui-that-is-good-but-not-usable--jorrdkvkz"},"datePublished":"2026-03-07T09:20:32.905Z","dateModified":"2026-03-15T03:52:30.060Z","description":"T3 Code is a new open-source GUI for agentic coding tools (currently supporting Codex only) by Theo, currently in alpha.
