Crew vs Jern Cloud
Crew gives you a local-first multiplayer agent workspace. Jern Cloud gives you a governed agent that opens a pull request. Here's which one fits your team.
Two agent tools launched close together and they point in opposite directions. Crew is a local-first multiplayer workspace where humans and agents share memory and threads. Jern Cloud is a governed cloud agent that runs under a repo-pinned policy and hands back a pull request (Crew, Jern). Here is how to pick between them.
Crew: collaboration over control
Crew is an open-source desktop app for macOS and Windows. You open a folder, connect your CLI-based model tools, and work with your own agents plus other people's agents on the same project. Agents can run multiple threads, use a ticket board, share memory, and fork work. There is no server and no account; everything stays local unless you share it.
The strength is speed of experimentation. Want to see what happens when two agents work the same codebase with shared memory? Crew makes that easy and free.
The weakness is governance. Crew gives you visibility into what agents are doing, but it does not give you a policy boundary, a hard token cap, or sealed evidence. It is a tool for people who trust their agents and want to move fast.
Jern Cloud: control over collaboration
Jern Cloud runs the agent on an isolated cloud machine under a policy pinned by the repository. It enforces a hard token cap, seals evidence, and opens a pull request for human review. Nothing runs on your laptop and no credential reaches the agent. It is $19 per month per workspace with your own Anthropic, OpenAI, or Gemini key, with a 30-day free trial (Jern).
The strength is auditability. For a team that needs to prove what an agent did, or that wants to let a junior developer run agents safely, Jern's model is the right one.
The weakness is friction. Every change goes through a pull request review loop, and the isolation boundary means you are trusting Jern's infrastructure in addition to the model.
Quick comparison
| Crew | Jern Cloud | |
|---|---|---|
| Where it runs | Local-first | Isolated cloud |
| Price | Free, open source | $19/mo per workspace |
| Policy enforcement | No | Repo-pinned policy |
| Token cap | No | Hard cap per attempt |
| Evidence | No | Sealed evidence |
| Delivery | Work in the app | Pull request |
| Best for | Multi-agent experimentation | Audited agent work |
Which one should you pick?
- You are a solo developer or small team exploring multi-agent workflows: start with Crew. It is free and the shared-memory model is genuinely different.
- You work in a team that needs approvals and audit trails: use Jern Cloud. The policy and evidence model is the point.
- You want both: run Crew for exploration and Jern for anything that touches production.
Neither tool is a finished product. Crew is early open-source software with expected rough edges. Jern is new and its workspace pricing needs to be planned around. Both are worth watching in the second half of 2026.
FAQ
Q: Can Crew and Jern Cloud work together?
A: They solve different problems. Crew is a local collaboration workspace; Jern is a governed remote execution environment. There is no official integration yet.
Q: Does Jern Cloud need a cloud model API key?
A: Yes. You bring your own Anthropic, OpenAI, or Gemini key, and sessions run on Jern's isolated infrastructure.
Q: Is Crew really free?
A: Yes, Crew is open source and free. It expects you to connect your own CLI-based model accounts.
