Devin is one agent in their cloud. Tandem is your fleet, on your box.
Devin is an autonomous AI software engineer — a single agent that plans, codes, and runs in Cognition’s hosted sandbox. Hand it a task, walk away, come back to a PR.
The trade you make is control and residency. Devin runs in their cloud. Your code, your context, and your build go off-box. You watch one agent through one timeline, and you trust the sandbox.
Tandem inverts that. You spawn agents in parallel across every project, each in its own isolated git worktree, and review them all from one inbox — diff, comment, approve, merge. It can run on your own hardware, with zero telemetry when you run local — or in our managed cloud, your call.
The two differences that matter
1. Your data can stay put. Devin is fully hosted — your code lives in their cloud. Tandem can keep code, vault, and history on hardware you control; your code can stay on your machine, or run in our managed cloud, your call.
2. One inbox for every model. Devin is a single proprietary agent with no model choice surfaced. Tandem routes every model and provider through one review inbox, and lets you run as many agents in parallel as your box can handle — then you ratify what merges.
Where Devin wins (we say so)
Devin’s end-to-end autonomy in a managed sandbox is genuinely hands-off: it provisions its own environment and drives a task to completion without you wiring anything up. If you want a fire-and-forget cloud engineer and you’re comfortable with hosted execution, that’s its strength. Tandem keeps a human approval gate in the loop on purpose — you stay in the driver’s seat — and it runs on infrastructure you own rather than rented sandboxes.
