Mirasim is a free Conductor alternative. Parallel agents, a worktree per task, teammates in the same session, agents that keep going after you close your laptop. Mirasim does all of it. It's free on your own machine, and your team's cloud can live on a box you already own, also free.
Does it have what I use every day?
Yes
Parallel agents, worktrees, diffs, PRs, merge, rewind.
Teams and cloud?
Both
Share a session with teammates. Agents keep going with the lid closed.
What does it cost?
$0 to start
Free on your machine. Free to use your own box as the team cloud.
Can I use my own plan?
Yes
Claude Code and Codex connect directly. We don't charge for that.
Is moving a pain?
One click
Worktrees, uncommitted changes and old chats stay right where they are.
A Conductor workspace is just a git worktree, and its chats are Claude Code's and Codex's own files. Mirasim reads them where they are. Nothing gets copied or converted.
The first time you open Get started, an import window pops up with the repos, worktrees and chats it found.
It's read-only. Your Conductor files aren't changed, copied or moved.
It takes a few seconds. Chats keep the titles they had in Conductor, and the window tells you which repos have setup or run scripts and which worktrees were archived.
Need to run it again later? It's under Import from Conductor… in the workspace menu.
Your worktrees sit under the repo, named by branch, and uncommitted changes are still in the Git tab. Your old Claude Code and Codex chats are there too. Send a message and keep going.
Used Conductor Cloud? Right-click each cloud workspace and choose Transfer to local first, then import.
Switch agents inside one session and the conversation carries over. No second thread, no pasting diffs back and forth.
Turn on Share with members and anyone in the space can reply in the same session. Every message shows who sent it.

Conductor starts deleting cloud data.
The local app starts winding down.
A few things Conductor had that we're still building:
Your Claude Code and Codex chats, yes. Import, open one, and keep going. For Conductor Cloud, use Transfer to local first, then import.
It's free on your own machine, using your own agent accounts and API keys. Making your own computer the team's collab space is free too. Hosted team spaces start at $49 per 30 days.
Each session can run in its own git worktree and branch, so they don't step on each other. A hosted team space is one machine, shared by the sessions in it.
Yes. Once the creator turns on Share with members, anyone in the space can send messages, and each one shows who sent it. Shared sessions run on a team API key or space credits. Subscription logins in a space are for the owner and admins only.
Yes. There are desktop apps for macOS (Apple silicon and Intel), Windows and Linux, and a headless Linux server joins with one command.
Your chats are Claude Code's and Codex's own files, and your worktrees are plain git. It's all on your machine, so you can take it anywhere.
The desktop app does. Hosted team spaces can't be reached from mainland China, Hong Kong or Macau.
Install Mirasim, click Import, and finish what you started in Conductor.
