Devin is a cloud-hosted autonomous software engineer that works alone on tasks. Fleet is a self-hosted orchestration layer that coordinates a team of Claude Code agents with governance, event-driven handoffs, and an audit trail.
Devin operates as a single AI engineer: you give it a task, it spins up a sandboxed environment, writes code, runs tests, and attempts to ship. It is a capable autonomous agent, but it is fundamentally one worker.
Fleet is not an agent. It is the coordination layer that manages many agents — developers, reviewers, release managers — against your real repositories. Where Devin replaces a single engineer, Fleet governs the workflow a team of agents runs through.
Teams that want to run multiple specialized agents in parallel with event-driven handoffs, approval gates, and a full audit trail — self-hosted on their own infrastructure.
Teams or individuals who want a single cloud-hosted AI engineer that can take on discrete tasks end-to-end with minimal setup.
| Feature | Fleet | Devin |
|---|---|---|
| Deployment model | Self-hosted Go binary, your machine or server | Cloud-hosted SaaS |
| Agent model | Coordinates a fleet of specialized agents (dev, reviewer, release-manager, etc.) | Single autonomous engineer agent |
| Coding model | Delegates to Claude Code (the agent runner) | Proprietary model bundled with service |
| Event-driven handoffs | Fabric event bus: PR created triggers reviewer, reviewer approval triggers release-manager | Not applicable — single agent handles full task |
| Data residency / source privacy | Self-hosted; your source code goes only to your model backend (Anthropic API, or Bedrock/Vertex in your own cloud) + GitHub | Cloud environment; code processed on their hosted backend |
| Approval gates | Per-stage human or agent approval gates with audit log | No built-in approval gate model |
| Pricing | Free (1 slot), Team $49/slot/mo, Enterprise custom | Per-seat + usage-based (ACUs); see their pricing page |
Fleet's Team tier is $49 per agent slot per month, and the Free tier includes one slot. Devin is a cloud SaaS with per-seat plus usage-based consumption (ACUs); see Devin's current pricing page for up-to-date figures.
These tools are more complementary than competitive. You can run a Fleet-orchestrated developer agent that uses Claude Code under the hood, and separately use Devin for isolated research or exploratory tasks that do not need to slot into your team's PR workflow. Fleet is the operating model for an ongoing agent team; Devin is an on-demand specialist you can call in.
Not directly — they solve different problems. Devin is a standalone AI engineer for discrete tasks. Fleet is the coordination layer for running a team of agents through your existing development workflow. If you want multi-agent orchestration with governance, Fleet is the answer. If you want a single autonomous engineer with a sandboxed environment, Devin is more relevant.
Fleet delegates actual coding to Claude Code. It does not bundle its own coding model. Devin uses its own proprietary model. Fleet is the coordination and governance layer that runs Claude Code agents in roles.
One binary. Five minutes. See every agent, coordinate every handoff, and keep a full audit trail of what your fleet did.
