Devin (by Cognition) is a fully hosted, proprietary autonomous AI software engineer. ShipIt is a self-hosted, open-source IDE where you bring your own agent — Claude Code or Codex — and keep everything on your own infrastructure. The core trade-off is hosted autonomy vs. owned control.
Devin sells hands-off autonomy as a polished service. It's a commercial product built around Cognition's own trained agent, running in their cloud. You assign a task and it works largely on its own. If you want maximum hands-off delegation and don't want to run any infrastructure, that's Devin's pitch.
ShipIt sells ownership and bring-your-own-agent. It runs on hardware you control, uses the agent you already pay for (Claude Code or Codex), and keeps you in the loop — steering in chat, reviewing each task as a pull request. You trade some out-of-the-box autonomy for control, reviewability, and not sending your code to a vendor's cloud.
| Capability | ShipIt | Devin |
|---|---|---|
| What it is | Self-hosted IDE that runs coding-agent CLIs through your real ship loop | Hosted, autonomous “AI software engineer” (Cognition) |
| Hosting model | Self-hosted — your VPS or local Docker, no ShipIt cloud in between | Hosted SaaS; Enterprise adds a Cognition-operated single-tenant VPC |
| License | Open source, Apache 2.0 | Proprietary / closed source |
| Agent / model | Bring your own — Claude Code or Codex, your subscription or API key, with several accounts per provider and automatic roll-over at a usage limit | Cognition's own proprietary agent |
| Where your repo is worked on | In containers on infrastructure you own | Cognition cloud; Enterprise uses a Cognition-hosted, customer-isolated VPC connectable to yours |
| Model traffic | Out to the Claude or OpenAI account you configure — self-hosting isn't local inference | Cognition's own agent; the reasoning layer stays in Cognition Cloud |
| Autonomy model | You steer in chat, interrupt mid-turn, review as PRs (opt-in merge-on-green) | Highly autonomous — assign a task and let it run |
| Isolated environment per task | Yes — one Docker container per session, on your infra | Yes — managed cloud workspace per task |
| Live app to test against | Yes — Docker Compose preview per session, with services the agent starts, stops, and tails itself | Has its own cloud workspace with shell/editor/browser |
| GitHub PR / CI / deploy loop | Inline — PR card, CI, review threads, deploy status in chat; one-click sync when behind the base, and sessions that wake on their own PR merge | Integrates with GitHub; opens PRs from its cloud |
| Issue tracking | Linear + GitHub Issues inline; start a session from an issue | Integrates with trackers; not a self-hosted inline tracker |
| Mobile | Mobile-first installable PWA, with voice in/out | Web app plus an installable desktop/mobile PWA; Slack-driven workflows |
| Maturity | Early public release; younger, narrower | Established commercial product with a trained autonomous agent |
Devin is an autonomous AI software engineer from Cognition, delivered as a hosted cloud service. You give it a task — often from Slack or its web app — and it works largely on its own inside a managed cloud workspace that has a shell, a code editor, and a browser, opening pull requests against your repository when it's done. It's a proprietary product built around Cognition's own agent; Devin Enterprise offers a single-tenant VPC deployment (still operated by Cognition), but you can't swap in a different model backend. Its strength is hands-off autonomy: delegating a well-scoped task and letting it run with minimal supervision.
ShipIt is a self-hosted, chat-driven IDE for running coding agents through your real engineering loop. You bring your own agent — Claude Code or Codex, on the subscription or API key you already have — and each task runs as a session in its own isolated Docker container, with a full clone of your repo and a live instance of your app to build and test against. The GitHub PR lifecycle, CI status, review threads, deploy status, and your Linear/GitHub issues all render inline in chat. It's open source under Apache 2.0, runs on a VPS you own or local Docker, and is mobile-first with voice.
Both are built around the idea of delegating a coding task to an AI agent that works in its own isolated environment and produces a pull request. Both integrate with GitHub and aim to take a task from description to reviewable change without you babysitting every step. If your goal is "assign work to an agent and get a PR back," both deliver that shape of workflow.
Devin is a mature commercial product built around a purpose-trained autonomous agent, and its whole design optimizes for hands-off autonomy — assign and forget. ShipIt keeps a human closer to the loop by default, which means more steering and reviewing, not less. If you specifically want a single, highly autonomous agent that needs minimal supervision and you're happy with a hosted SaaS, Devin is built for exactly that and ShipIt is not trying to match its autonomy out of the box. ShipIt also asks you to run infrastructure (Docker on a machine you own), where Devin asks nothing of you but a login.
If having a vendor operate the platform that holds your repository is a non-starter, ShipIt is the answer: the orchestration, workspaces, and previews run on infrastructure you control, with container-isolated sessions, a per-agent default-deny outbound firewall, and brokered git credentials. It's agent-agnostic, so you use the model you already trust and pay for rather than a single proprietary agent — across several accounts per provider, rolling over automatically when one hits a usage limit. And because every task is a reviewable PR with a live app to test against, plus issues and CI inline, teams that want control and auditability — not just a black box that returns a diff — tend to prefer ShipIt's shape. Guardrails back that up: destructive git on already-merged work gives way to a brokered reset that leaves a record, a commit carrying a recognized secret is blocked outright, and an update or a crash mid-turn doesn't strand the work. It's also mobile-first and installable to your home screen — though Devin ships an installable PWA of its own now, so phone access is no longer a point of difference.
Yes, in spirit. Both let you hand a coding task to an AI agent that works in an isolated environment. ShipIt is open source (Apache 2.0) and self-hosted, and you bring your own agent — Claude Code or Codex. Devin is a proprietary, fully hosted SaaS built around Cognition's own agent. If 'open-source, self-hosted Devin alternative' is what you're searching for, ShipIt is a close match on the workflow, with a different ownership model.
Mostly no. Devin's standard product is a hosted cloud service run by Cognition. Devin Enterprise offers a single-tenant 'Customer Dedicated Deployment' — a customer-isolated VPC that Cognition hosts and operates and can connect to your own VPC, with the agent's reasoning still running in Cognition Cloud. The agent stays proprietary, you can't bring your own model, and it isn't open source. ShipIt, by contrast, is open source and runs on infrastructure you control — a VPS or local Docker. Both still send context to a model provider, so the real distinction is who operates the platform your repository lives in.
Devin is positioned as a highly autonomous 'AI software engineer' you assign tasks to and let run. ShipIt keeps you closer to the loop by default: you steer the agent in chat, can interrupt mid-turn, and review each session as a pull request — though you can also arm a trivial task to merge on green. ShipIt is less hands-off out of the box, which some teams prefer for control and reviewability.
In ShipIt, yes — it's agent-agnostic, so you pick Claude Code or Codex per session and use your own subscription or API key. With Devin you use Cognition's agent; you don't swap in a different coding-agent backend.
Run coding agents on your own infrastructure, with the agent you already pay for, and review every task as a pull request.
