Devin is a hosted autonomous engineer that works in its own cloud; o8 is local-first and runs a fleet of agents on your machine, under a gate you control.
Devin is a cloud autonomous software engineer: you hand it a task and it works in its own hosted environment, largely on its own, then comes back with a result. The model and the machine it runs on are managed for you.
o8 is a local-first desktop control room for autonomous engineering. One orchestrator dispatches a fleet of coding agents — each in its own isolated git worktree — and a governance layer reviews every diff. Nothing merges unreviewed, and nothing risky merges without your sign-off. It runs on your own machine with the subscriptions or keys you already use, and normalizes 16 dispatchable agent runtimes behind one adapter contract in the current public release.
Two real differences. First, where it runs: o8 keeps repositories, worktrees, sessions, approvals, and memory on your machine (state lives in ~/.o8), while prompts and context leave only through the model route you choose. Second, who’s in charge: o8 is built around the operator. You watch the fleet, steer mid-flight, and every diff waits behind a review gate instead of an agent merging autonomously. It’s orchestration with oversight, not hands-off delegation.
If you want a hosted agent to take the wheel, that’s Devin’s model. If you want a fleet of agents running locally with approvals, audit, and your existing model access, that’s o8. More on the pricing and methodology pages.
