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.
Run several Claude Desktop apps at once, one per account
With Opus 5.5 a user built a way to run multiple Claude Desktop instances side by side, each signed into a different account with its own taskbar icon, plus one window showing every account's 5-hour and weekly limits.
Hand coding work to T3 Code by voice through Grok Bot
A developer connected Grok Bot to T3 Code over MCP and spent the day on a 4+ hour voice call with his bot, handing off coding tasks while walking around without touching his Mac.
Measure how much of your usage limit resuming a long session costs
A developer tested resuming long sessions in Claude Code with Opus 5.5 and in Codex with GPT-6.1 Sol, both on medium effort, and watched the usage meters. Resuming a long Claude Code session took a big chunk of the 5-hour limit, while codex resume did not show the same jump.
