What you get
- Real terminal panels. Each agent is the actual CLI in its own terminal panel, in your project folder. Up to 12 per workspace, and as many workspaces as you like.
- Live status. The Overview shows every agent as a card: Working, Needs you (for example a permission prompt), Waiting on agents, or idle.
- Agents pass work along.
tnai sendlets one agent message another by name: Claude Code asks Codex for a review, Codex finds the bug, Claude Code fixes it. No copy-pasting. - Leads and sub-agents. A Claude Code, Codex or OpenCode lead can start a sub-agent on another CLI in a new terminal panel and get its report back.
- Separate worktrees. Tick Own worktree and an agent works in its own git branch and folder, so two agents don't trip over the same files.
- Conversations come back. Claude Code and Codex conversations resume after a restart: press Enter in the stopped panel.
How to set it up
- Install Claude Code and Codex and sign in to each. Technically Not finds them and shows which account each one uses.
- Open your project folder in Technically Not.
- On the Terminal page, add a terminal panel and choose Claude Code; add another and choose Codex.
- Type in either panel, or write in the prompt box and send it to the agent you selected.
One of them hitting a usage limit? You can add several accounts and switch Claude Code accounts when one hits its limit.
What it doesn't do
- It doesn't include any AI. You pay for your own Claude Code and Codex plans as usual.
- Claude Code reports each step to the app. Codex doesn't, so its status comes from its output and its session file (a task clock and its results), and part of it is inferred.
- Two agents in the same folder can still edit the same file. Use Own worktree (needs git) or give them separate parts of the project.
- Windows 10/11 and Linux only for now; Mac is coming.
Doing it by hand instead
You can run both agents without Technically Not. Here's how the options compare, including where each is better.
| Option | How it goes | Where it's better |
|---|---|---|
| Separate terminal windows or tabs | One CLI per window. You check each one and copy text between them. | Free, lightest, nothing new to learn. |
| Each company's own app | One app for each agent, made by the company behind it. | Made by the people who build the agent; their new features tend to arrive there first. |
| Technically Not | Both CLIs in one window on the same project, with live status and tnai send between them. | One place to see who's working and who needs you, and agents that hand work over themselves. Paid, Windows and Linux only. |
What it costs
Pro is $15/month or $144/year. The Founder price is $99/year until December 25, 2026. No free plan and no trial; the live demo shows the real interface before you buy. See pricing.
Questions
Can Claude Code and Codex work on the same project at once?
Yes. Each runs in its own terminal panel in your project folder. To keep their edits apart, give one of them its own git worktree, or split the work by folder.
Can Claude Code hand work to Codex?
Yes. From any agent's terminal, tnai send passes a message to another running agent by name, and a Claude Code lead can start a Codex sub-agent in a new terminal panel and get its report back.
Is it the real Claude Code and Codex?
Yes. Technically Not starts the CLIs you installed, signed in with your own accounts, in real terminals. It doesn't replace or imitate them.
Which other agents can run next to them?
Cursor Agent and OpenCode work with fewer features, GitHub Copilot CLI launches with basic support, and Gemini CLI and Droid are experimental. Any terminal panel can also run a plain shell.
Is there a free plan or trial?
No. Pro is $15/month or $144/year, and the Founder price is $99/year until December 25, 2026. You can try the real interface in the browser before you buy.
