Will codemax cost me extra?

No. codemax is free and open source, and it only uses the subscriptions you already pay for. It never bills an API key, and it warns you if anything on your machine would.

Does it replace Claude Code or Codex?

No. Those agents still do the work. codemax is the one place you use them from, so you can move between them freely and never start from scratch.

Everything runs on your machine. Your code goes only to the agents you already use, under your own accounts, and every edit asks for your approval first.

Which agents does it work with?

Claude Code, Codex, OpenCode and Grok today, with Gemini CLI, Cursor and Copilot next.

Developers who pay for more than one AI coding plan and are tired of hitting a limit in the middle of real work.

Free · Open source

Every AI coding plan you pay for. One terminal.

Use Claude, Codex, Grok and more side by side. When one hits its limit, the next carries on with your task — same context, no restart.

The problem

Limits always hit mid-task.

You pay for two or three AI coding plans, yet you still get stopped: one runs dry, and switching means re-explaining your whole project. With codemax, your work simply moves to the next agent and keeps going.

Why codemax

Three reasons people switch.

Get the most from every plan

Stop letting one subscription sit idle while another runs out. Use all of them, from one place.

Stay in flow

No more copy-pasting context into a new tool. Your task, history and changes travel with you.

No surprise bills

codemax only ever uses the plans you already pay for. Never a pay-per-token API key.

Fig. 03Pieces that fit together

Never stalls on a limit

When one agent runs out mid-task, the next one carries on with the request you were working on.

Context that follows you

Every agent sees what the others did: the conversation, the changes, what's still to do.

Daily budgets

Decide how much of each plan to use per day. codemax hands off before you hit the wall.

See what you get

Know exactly how much work each subscription is doing for you, side by side.

One-step undo

Didn't like what an agent changed? Roll its last turn back instantly.

Second opinions

Ask another agent a quick question without leaving the one you're working with.

Bring any file

Type @ and pick a file; every agent gets it in context.

You stay in charge

Agents still ask before they edit or run anything. Nothing happens behind your back.

Up and running in a minute.

Free and open source. Uses the logins you already have — nothing new to sign up for.
