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%.

Introducing Coshell

AI coding tools made developers individually multiplayer with machines; Coshell makes the team multiplayer with the machine.

Coding agents are single-player. They made one engineer faster and left the team’s coordination worse. Context gets duplicated, work happens where nobody else can see it, and a handoff means pasting memory files to the next person.

Coshell is a shared environment for people and agents. Several people prompt the same live agent inside one drive with a filesystem, a command environment, and a localhost browser. Your teammate doesn’t resume from your notes. They resume from the session.

Multiplayer

One live session,
with the whole team in it.

Closer to a shared document than to git. Instead of everyone taking a copy and merging later, there is one running environment that everyone sees live.

PriyaAdd the orders overview: revenue, order count, average order value.
TomUse var(--brand) for the Export button, not a hardcoded hex.

Overlap

Two agents, one file,
nothing clobbered.

Before an edit lands, Coshell checks whether another session is working the same path. If it is, the edit is held and a reasoning arbiter reads what both sides are actually changing, then tells that agent how to proceed. Every decision is recorded. It fails open, so it never stalls work.

Runs where your code lives. Bring your own machine.

A drive runs wherever you want it to: the laptop you are typing on, the Mac mini under the desk, one click on Render, Railway, or Northflank, or a cloud-init file on any VM. It binds to localhost, connects out over a WebSocket, and opens no inbound ports, so your code never leaves your machine.

Your machine
$ curl -fsSL https://coshell.ai/install | bash
$ coshell host init
Your own laptop is a drive too. Teammates reach it through the tunnel while it is awake, and the doctor warns you before the machine would sleep on them.Waiting for the first command
Mac mini
$ curl -fsSL https://coshell.ai/install | bash
$ coshell host init
The Mac under the desk becomes a drive for the whole team. A launchd agent keeps it running and reconnects after a reboot.Waiting for the first command
RenderDeploy to RenderOne background worker with a 20 GB disk. The button opens Render’s template; paste your enroll token when it asks and the drive is online for the team.Waiting for the first command

Access per sessionKeep a session private, share it with a few teammates, or open it to everyone on the drive.
Credentials stay on the driveKeys are configured once on the machine and scoped by the same access rules, not spread across laptops.
Identity verified at the edgeThe drive never trusts a client. The edge injects who you are, so attribution and access cannot be spoofed.
Session chat

Talk where the work is.

Every session has its own chat. Mention a teammate to pull them in, mention a file to point at it, ask @coshell what the team is up to, follow someone to see what they see, and get notified in the web app or the terminal.

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%.

Fits your stack

Works the way your team already works.

Coshell sits on top of the agents and the git workflow you have. Nothing to migrate.

Your agents Claude Code, OpenAI, and more than 70 models. Admins choose which providers the team can use and set a default model, applied live to every running drive.

Your git Work in a drive pushes to your repository as a normal git operation. Branching, review, and CI stay exactly as they are.

Your terminal coshell attach opens the same drive in a TUI, with presence, chat, and follow, so nobody has to leave the terminal.

Any device The environment lives in the cloud, so a session is reachable from a laptop or a phone. Teams have fixed live issues from a phone.

Up and running in a minute.

Three ways in. They all end in the same drive, with your team on the link.

In the browser

  1. Sign up and name your org.
  2. Pick where the drive runs: a machine you have, or a cloud provider.
  3. Paste the two commands the wizard gives you, or click through the provider template.
  4. Send your team the link.
Start free

From the terminal

  1. Install the CLI. macOS and Linux; Windows runs it inside WSL.
    $curl -fsSL https://coshell.ai/install | bash
  2. Run coshell signup. It creates the account, names the org, and enrolls this machine as your first drive, in one go.
  3. Send your team the link.

Already signed up? coshell host init adds this machine as another drive.

Let your agent do it

  1. and paste it into Claude Code, Cursor, or any coding agent on your machine.
  2. It installs the CLI, runs signup, and asks you for the details instead of inventing them.
  3. It tells you when setup is complete.

Questions teams ask before they switch.

Coshell works with those agents rather than replacing them, across more than 70 models. The single-player tools made each engineer faster and left the team’s coordination worse. Coshell is the layer that makes the team work with the agent together: shared live sessions, overlap handling when code is written, shared context, and one standard environment.

A cloud dev environment gives one person a machine in the cloud. Coshell is built around several people and the agent working in the same live environment at once, with prompts that queue in the open, overlap negotiation, and agent context that everyone shares.

Because everyone works in one live environment instead of separate copies, the worst kind of collision never forms. When two efforts still touch the same concern, the overlap layer detects it, holds the second edit, and a reasoning arbiter decides how that agent should proceed based on what both sides are actually changing. It never merges code, and every decision is recorded.

No. Most engineers already sit in a terminal in front of a coding agent. Coshell gives you the same session in the web app or the TUI, your git workflow stays exactly as it is, and a new teammate gets a working environment in seconds instead of a day of setup.

On the drive, which can be your own machine: a Render or Railway worker, any VM, a Mac mini, or a laptop. The drive connects out to the edge over a WebSocket and opens no inbound ports. Your repositories stay yours through normal git, so there is nothing to migrate away from.

Free to start on your own machine: you bring the compute and nothing is metered. Enterprise adds SSO, role-based access, an audit trail, priority support, and Coshell on your own infrastructure at scale. Email enterprise@coshell.ai and we set your team up.
