Warp shares your machine's session. Coshell is one neutral session for the team.

Warp is a fast agentic terminal, and it can share a live session from a host's machine. Coshell is a different shape: a *neutral cloud session* the whole team owns and works in together, with one agent.

Host-shared session vs neutral team session

Warp is a great agentic terminalA fast, modern terminal turned agentic development environment, with strong in-terminal agents, cloud orchestration, and an open-source client. As a per-developer tool it is genuinely excellent.

Warp can share a sessionIt is not single-player only. A host can publish their session and let others view or run commands. The difference is what is shared, and where it lives.

Coshell is neutral and sharedThe session lives in a team drive in the cloud, not on anyone's machine. Everyone joins the same one and prompts one agent together.

Warp shares one developer's session, running on their machine.

Coshell puts the whole team in one neutral cloud session with one agent.

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%.

Steps

What Coshell adds for a team.

Not a terminal per developer, and not a session anchored to one machine. A neutral cloud session the team shares, with one agent. Every line below is running in production today.

One team-owned session, not someone's machine shared out

In Warp, a host shares their own session, running on their machine, and others operate it remotely. In Coshell the session lives in a cloud drive the team owns, so no laptop has to stay on and everyone is a first-class participant in the same running environment.

Your whole team on one drive, one price

Warp is priced per user with metered AI credits. Coshell is free to self-host, no seats: run a drive on your own machine, your whole team in your org, unmetered, and no per-seat charge.

The workspace stays warm, on any device

A drive stays warm in the cloud with your files, terminal, and an integrated browser preview, reachable from any browser or the CLI. There is nothing to install and no host session to keep alive for teammates to work.

Bring your own keys across 70+ models

Coshell runs 70+ models on your own provider keys, scoped per drive, billed by your provider. It is built on OpenCode, which, fittingly, is also one of the agent harnesses Warp can run.

Coshell vs Warp, side by side.

	Warp	Coshell
What it is	A fast agentic terminal and dev environment, per developer	A shared cloud session a whole team works in with one agent
Where the session runs	On the host's machine; cloud agents orchestrate in the background	In a team-owned cloud drive: shared filesystem, terminal, browser preview
Live collaboration	Host shares their session; others view or run commands	Everyone joins one neutral session and prompts one agent together
Anchored to	The host developer's machine	A team-owned drive, no laptop dependency
Pricing basis	Per user, plus metered AI credits	Free to self-host, no seats
Team size	Priced per user	Your whole team, one drive
Models	Bring your own key; multiple agent harnesses	Bring your own keys, 70+ models, built on OpenCode
Where you work	A terminal app on your machine	Any browser, or the CLI, nothing to install
Best for	A best-in-class agentic terminal per developer	A team working with one agent in one shared session

Keep your terminal. Add the shared session.

Many engineers keep a fast terminal for their own work and join a shared Coshell drive when the work is shared. Coshell runs your own repo on your own model keys, pushes to your real git, and is free to self-host, so the whole team can be in one session without a per-head bill.

How multiplayer works See the product Pricing, free to self-host

Built on OpenCode

Coshell vs Warp, answered

Doesn't Warp already have multiplayer session sharing?

It does, and it is good. The difference is architecture. In Warp, one person hosts their session, running on their own machine, and grants others view or edit access, so collaborators operate the host's environment remotely. In Coshell the session lives in a cloud drive the team owns, so there is no host machine to depend on, everyone is a first-class participant in the same persistent environment, and there are no seats to buy.

Can a team use Coshell and Warp together?

Yes. Many engineers keep a fast terminal like Warp for their own work and join a shared Coshell drive when the work is shared: pairing, debugging together, onboarding, live review. Coshell is built on OpenCode, which Warp can also run as an agent harness, so they sit comfortably in the same toolbox.

How does pricing compare?

Warp is priced per user with metered AI credits, so cost scales with headcount and usage. Coshell is free to self-host, no seats: run a drive on your own machine, your whole team in your org, unmetered. Bring your own model keys on either, billed by your provider.

Can I bring my own models and keep my code in-house?

Yes. Coshell runs 70+ models on your own keys, scoped per drive, and a drive pushes to your real git as ordinary git. Self-host it on your own machine and your code never leaves it, free; the Enterprise tier adds org-wide on-prem, so your code never leaves your environment.

Get your team in the same session.

Start free

Keep your terminal for solo work. When the work is shared, open a drive and put the whole team in one neutral live session with one agent.
