01Agents

Every agent and subagent, in its place.

Your conversations are organized by project. Inside each one you see the whole tree: the main agent, the subagents it spawns, and the ones those spawn in turn. Click any of them to see exactly what it did.

Live status: thinking, waiting for your permission, or done.
Tokens, time and cost for every agent, not just the session.
See which worktree and branch each agent worked on, and which files it changed.
Large waves are grouped so the tree stays readable.

All your projects open. One place.

Several projects at once

Switch projects without closing anything. Each one keeps its agents, tabs and terminals, and tells you when something needs your attention.

06Questions

Frequently asked questions

When can I download it?

We're in early access. Join the waitlist and we'll email you when the first build is ready.

Is it really free?

Yes. The Community edition is open source (AGPL-3.0), needs no account, and works with local models like Ollama or LM Studio.

Can I use my Claude subscription?

Not from the app's agent: Anthropic doesn't allow third-party apps to offer that sign-in. You can use Claude with an API key, or open the official claude CLI in the built-in terminal, like in any terminal. Those sessions still show up in your history.

What about my ChatGPT subscription?

Yes. You sign in with Codex CLI itself (codex login), and Alchemist Coder never sees your token.

Do you charge for tokens?

Never. You use your own accounts and API keys and pay each provider directly. We only charge for the app.

What data do you store?

In Community, nothing leaves your machine. When Pro launches, synced data will be end-to-end encrypted before it leaves your computer, so we won't be able to read your conversations or your code. The only thing we store today is your waitlist email.

How do I contribute?

The repository opens at public launch. From then on, open an issue or a pull request on GitHub; before your first PR we'll ask you to sign the contributor license agreement (CLA).
