Conductor's multiplayer runs in their cloud. Coshell's runs on your own machines, free.

Conductor is the best way for one person to run Claude Code, Codex, and Cursor in parallel on a Mac, and since July it has shared cloud workspaces on its Pro tier. Coshell is the shared live session for your whole team, with as many agents and sessions as you want, on drives you host yourself. Here is the honest comparison.

Spec approvedPlan approvedExecuting 3/5

Goal

Protect /v2 from bursty API keys without slowing normal traffic. One key should never be able to starve the others.

Approach

A token bucket per API key, 100 requests per minute, stored in Redis so all three replicas share state. Over-limit requests get a 429 with a Retry-After header. Ship behind the rate_limit_v2 flag and roll out gradually.

Constraints

No new dependencies beyond ioredis, which we already run.
p99 latency budget: +2 ms on the hot path.
Existing tests stay green at every step.

Verification

bun test after every step. Load test with 1k keys before the flag moves to 50%. Watch 429 rate and p99 in the dashboard for a day at 10%.

The difference is where multiplayer runs, and what it costs.

Your code stays on your machines.Conductor's multiplayer needs Conductor Cloud, so the repo runs on their microVMs. A self-hosted Coshell drive keeps it on your laptop, VM, or container, and the team still joins the same session.

Multiplayer that is free to self-host.Conductor's multiplayer needs a Pro plan: $50 a month for up to 5 users, then $60 per person on Teams. Coshell's multiplayer is free on a drive you host; Enterprise is the paid tier.

Collision seen now, not at merge.Worktrees stop file collisions. The overlap layer watches for two efforts on the same concern while they happen, across sessions.

Conductor vs Coshell, side by side.

	Conductor	Coshell
What it is	A Mac app that runs parallel coding agents in isolated workspaces, with a cloud tier	A shared live session your team runs its agents in, on drives you host yourself
Where multiplayer runs	Conductor Cloud, their microVMs, Pro and up	Your own machine, VM, or container, free
Agents and sessions	Several agents for one developer, one per worktree	As many agents and sessions as the team wants, shared or private, on one drive
Working the same branch together	One workspace per branch; a teammate forks a second branch	One working tree, queued visible prompts, no fork
Overlapping changes	Isolated until merge, then inspected by hand	Overlap layer catches the same concern being changed twice, while it happens
Context	Fresh agent and fresh checkout per workspace	Long-lived sessions, codebase loaded once per drive
Environment lifetime	Cloud workspaces sleep at 4h idle, stop at 23h50m	Drives persist; sleep when idle, wake in seconds
Clients	macOS app; API; SSH; mobile coming	Browser, CLI, VS Code, phone
Models	Claude Code, Codex, Cursor, OpenCode; your keys	70+ models on your keys, including a Claude Pro or Max subscription
Privacy	Workspaces shared with the organization (per their docs)	Per session: private, named teammates, or whole drive
Git identity	Your local git and gh on your Mac	Commits by the prompter, PRs as the connected person, no token on the drive
Review	Diff viewer with line comments, Checks tab (ahead of ours)	Review tab in the session, plus your normal GitHub review
Self-hosting	Local Mac only; cloud is theirs	Your laptop, VM, or container, free; Enterprise on-prem
Pricing	Free local; Pro $50/mo up to 5; Teams $60/user/mo	Free to self-host; Enterprise is paid
Best for	One developer running many agents on a Mac	A team working together in live sessions, on its own machines

Conductor vs Coshell, answered

Is Coshell a replacement for Conductor?

Not for a solo developer on a Mac. Conductor is the better tool for one person running several agents in isolated worktrees, and its free tier is generous. Coshell is for the moment a second person needs to be in the same work: one live session the whole team is in, on a drive you host. Some teams will use both.

Conductor has multiplayer now. What is different?

Conductor's multiplayer (July 2026) is a Pro feature that runs in Conductor Cloud: teammates open a shared cloud workspace, see who is there, and prompt together, at $50 a month for up to five people. Coshell's multiplayer is the product, and it is free on a drive you host: every prompt carries who sent it, sessions are private or shared, overlapping work is detected across sessions, and your code never leaves your machine.

Can my team run several agents at once in Coshell?

Yes. A drive holds as many sessions as you want, each with its own agent, its own branch or worktree if you like, and its own privacy setting. The difference from Conductor is that teammates can be in the same session at the same time, and overlap between sessions is watched while it happens.

Isn't isolation safer than sharing one working tree?

For file-level collisions, yes, and Conductor does it well. But isolation defers the other kind of collision, two changes to the same concern in different files, to merge time. Coshell's overlap layer looks for that while it happens, and a shared tree means there is no divergent copy to reconcile later.

Can I use my existing Claude subscription?

Yes, on both. Conductor runs your Claude Code login locally. Coshell runs it on the drive through the Claude Code binary, alongside 70+ models on your own keys.

What about running on our own machines?

Conductor's local mode is your Mac, and its collaboration runs in Conductor Cloud. Coshell's self-hosted drives run on your laptop, a VM, or a container, free, and the whole team joins the same session in a browser; Enterprise adds org-wide on-prem and SSO.

Get your team in the same session.

Start free

Keep Conductor for solo work on your Mac. When the team needs to be in the same work, self-host a drive for free or open a hosted one, and put everyone in one live session.
