Codex made one developer faster. Coshell makes the whole team work with the agent together.

Codex and Coshell both write code with an AI agent. The difference is how many of you are in the room. Codex is one developer and one agent. Coshell is your whole team and one agent, in the same *live session*.

It is a fork of OpenCodeCoshell runs Codex's models the same way your own tools do: through OpenAI keys you control, alongside 70+ other models. We did not rebuild the agent.

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%.

Single-player Codex, made multiplayer.

The axis is not a better agent. It is the layer between the people. Codex is one developer and one agent. Coshell takes that same kind of agent and puts your whole team in one live session with it.

Codex is one seat. Coshell is the room.

Codex pairs one developer with one agent in one terminal. Coshell puts several people in the same live agent session at once, on a shared filesystem, terminal, and browser. Everyone prompts the same agent and watches the same work land. It is closer to a Google Doc than to git.

Two people, one agent, no clobbering.

With one agent per person you merge afterward, and you find the conflicts later. In a shared Coshell session there is no diverging copy to lose, and when two agents reach for the same lines of the same file, an overlap layer catches it and steers the second one before it clobbers the first.

One warm context, shared by the whole team.

Codex reloads context for every developer who runs it. Coshell's shared session ingests your repo once and keeps it warm, so each teammate reads from a context that is already built instead of paying to load it cold. The more context-heavy the work, the more that compounds across the team.

Pairing with the agent

Nothing about your models or your git changes. Coshell is a fork of OpenCode that runs OpenAI's models on your own keys, alongside 70+ others. What is new is the layer Coshell adds: one live session your whole team shares, presence, follow-along, and overlap detection. Pay free to self-host, no seats.

Built on OpenCode

Questions, answered

Codex and Claude Code make one developer faster, alone: one person, one agent, one terminal. Coshell is the multiplayer layer. Several people work in the same live agent session at once, on a shared filesystem, terminal, and browser, with presence, follow-along, and an overlap layer that catches overlapping edits before they clobber. It is the same kind of agent, built for a team instead of a seat.

Yes. Coshell runs 70+ models, including OpenAI's, scoped per drive and billed by your provider on your own keys. Admins pick the allowed set and a fallback. You are not switching models, you are putting your team in one session that uses them together.

No. Two things prevent it. Because everyone works in one shared environment, there is never a second copy drifting out of sync, so the conflicts you would normally merge later never appear. And when two agents reach for the same lines of the same file, the overlap layer catches it and holds the second edit before it clobbers, steering that agent to take other lines, wait, or let the first land first.

No. Work in a drive commits and pushes to your own repositories like any other git remote, so your branches, reviews, and CI keep working as they do today, and nothing is locked inside Coshell. On the Enterprise tier adds org-wide on-prem and SSO; either way, self-host keeps your code on your own machine.

Bring your team into the session.

Keep the OpenAI models you already use. Add the room everyone codes in together. Open a drive in the browser, or attach from the CLI.
