How to run Claude Code and Codex in a desktop app (T3 Code, Codex app, Claude Desktop) · How to compare AI models on the same prompt
Related use cases
Measure how a new coding app affects your Claude usage limits
After switching to T3 Code the same week Claude Desktop shipped a UI update, a developer tracked his usage and found each 5-hour window fit about 44% less work on the same Opus 5.5 model, with cache hits around 98.7%.
Recover your Claude Code Desktop sessions after switching accounts
When you switch Claude accounts (for example personal to Team), the Code tab in Claude Desktop starts empty even though nothing was deleted. claude-migrate moves your Code sessions to the other account on the same Mac so they show in the sidebar again.
Try T3 Code as your desktop app for Codex and Claude
A developer gave T3 Code a real try and found it close to daily-driver ready, saying it beats the official Codex and Claude desktop apps.
Turn a spare Android TV box into an always-on host for your AI agent
A builder had Claude Code inspect the Android TV box from his TV provider from a prompt and one photo, install a Linux shell built for its chip, add a wake lock and battery whitelist so Android cannot kill the agent, and wire the agent to his own Telegram bot with no open ports.
