OpenHands vs Devin vs Manus – AI Agent Features Compared (2027)
The jump from AI chatbots to AI agents is the biggest shift in software since the cloud. Instead of answering questions, agents do work: they plan, browse, write code, run tests, and hand back finished results. Three names lead the pack in 2027 — OpenHands, Devin, and Manus — but they take very different paths to the same goal. This guide compares OpenHands AI agent features vs Devin vs Manus on what actually matters: what each one does, what it costs, where it shines, and which fits your workflow.
What Is OpenHands?
OpenHands (formerly OpenDevin) is the open-source platform for autonomous software development agents. You run it yourself — typically via Docker — and it works in a loop: inspect your repository, plan the task, edit files across the codebase, run commands and tests, read the results, and iterate until the job is done. Because it is model-agnostic, you can plug in Claude, GPT, or open-weight models of your choice.
Key features include multi-file code editing, terminal command execution, web browsing for documentation, built-in task tracking, and an agent hub with 10+ specialized agents. Being open-source means no seat fees and full control: your code never leaves your machine unless you choose a cloud model. For developers who want power without a subscription, it is the most flexible option of the three.
What Is Devin?
Devin, built by Cognition AI, debuted in 2024 as the “first fully autonomous AI software engineer” and has matured into a serious engineering tool. It lives in its own cloud virtual machine with a browser, terminal, and code editor. You assign tasks through Slack, Linear, Jira, or the web app — Devin plans the work, writes and tests code, and opens pull requests, even responding to review feedback.
Pricing is usage-based: Core starts around $20/month pay-as-you-go, Team runs about $500/month, and Enterprise is custom — billed in ACUs (Agent Compute Units, roughly 15 minutes of active agent work each). Recent versions added dynamic re-planning when tasks stall and a faster execution mode. If you want maximum hands-off autonomy and can pay for it, Devin is the most polished choice.
What Is Manus?
Manus (by Butterfly Effect) is a general-purpose AI agent, not just a coding tool. Give it a multi-step job — deep market research, data analysis, slide decks, even working web app prototypes — and it plans the work, browses real websites, writes and runs code in a cloud sandbox, and returns finished artifacts with a replayable session log showing how it got there.
Pricing is credit-based: a free tier with 300 daily credits, Pro from around $20/month (4,000 credits), and higher tiers up to about $200/month. Simple tasks cost tens of credits; complex builds can burn hundreds, so costs scale with usage. For research-heavy and mixed-media work beyond pure coding, Manus is the most versatile of the three. If your needs lean toward AI voice agents or other business automation, that same “general agent” idea applies.
OpenHands vs Devin vs Manus: Side-by-Side Comparison
| Feature | OpenHands | Devin | Manus |
|---|---|---|---|
| Open source | Yes (fully) | No (closed SaaS) | No (closed SaaS) |
| Hosting | Self-hosted (Docker) | Cognition cloud VM | Manus cloud sandbox |
| Primary strength | Autonomous coding | Autonomous software engineering | General multi-step tasks |
| Model choice | Any (Claude, GPT, open models) | Cognition’s models | Multi-model orchestration |
| Browser + terminal | Yes | Yes | Yes |
| Team integrations | Via setup | Slack, Linear, Jira, GitHub natively | API + web app |
| Starting price | Free (pay your own infra/API) | ~$20/mo | Free tier; Pro ~$20/mo |
| Best for | Developers wanting control | Teams wanting autonomy | Research + builds beyond code |
Pricing Compared: What Will You Actually Pay?
- OpenHands: $0 for the software itself. Your real costs are model API calls and whatever machine you run it on — from a laptop to a VPS. For solo developers, this is by far the cheapest path to a capable coding agent.
- Devin: ~$20/month gets you in the door on Core, but real team usage lands in the hundreds per month once ACUs add up. Budget for it like a junior developer salary line, not a SaaS seat.
- Manus: the free daily credits cover light use. Regular individual work fits the ~$20/month tier; heavy daily automation climbs toward $200/month fast since complex tasks burn 500+ credits each.
The honest rule: OpenHands wins on price, Devin wins on polished autonomy, Manus wins on versatility per dollar for mixed work.
Strengths and Weaknesses
OpenHands — Strengths: free and open-source, your code stays private, endlessly customizable, no vendor lock-in. Weaknesses: you handle setup, hosting, and model keys yourself; less hand-holding than commercial tools.
Devin — Strengths: the most autonomous coding experience, excellent Slack/Linear/GitHub workflow, strong at multi-step engineering tasks. Weaknesses: expensive at team scale, your code runs on Cognition’s cloud, and long tasks can still drift without clear scoping.
Manus — Strengths: handles research, data, docs, and prototypes in one place; generous free tier; easy to start. Weaknesses: credit costs are hard to predict, less specialized for pure software engineering than Devin or OpenHands.
Which AI Agent Should You Choose?
- Want full control and zero license cost? Pick OpenHands. Self-host it, choose your model, keep your code private. Pair it with AI agents that automate daily work for non-coding tasks.
- Want a hands-off coding teammate? Pick Devin. Assign tickets in Slack, review the PRs it opens. Best when engineering time is your bottleneck and budget allows.
- Is your work research, analysis, and prototypes — not just code? Pick Manus. It shines where the deliverable is a report, deck, or working prototype rather than a pull request.
- Test before you commit. All three have free or cheap entry points. Run the same real task through each and compare the output quality — that one test beats any review.
- Check your constraints. Regulated industries or strict IP rules favor self-hosted OpenHands; fast-moving product teams often prefer Devin’s managed autonomy. Small businesses should also look at AI tools for small businesses and AI automation tools to round out the stack.
Frequently Asked Questions
OpenHands is an open-source autonomous coding agent you host yourself; Devin is Cognition’s closed, cloud-based autonomous software engineer focused on coding tasks; Manus is a general-purpose cloud agent that handles coding plus research, data analysis, and building prototypes.
The software is free and open-source. You still pay for the AI model API calls it makes and for the machine you run it on, but there are no seat fees or subscriptions.
Devin offers the most polished, hands-off coding experience with deep Slack and GitHub integration, but it is expensive and cloud-only. OpenHands matches much of the capability for free if you are comfortable with self-hosting and setup.
Manus can write and run code in its cloud sandbox, but it is a generalist — Devin and OpenHands are more specialized for software engineering workflows like multi-file refactors, test runs, and pull requests.
For Manus, no — it handles research and general tasks in plain language. For OpenHands and Devin, basic coding knowledge helps a lot: you need to review diffs, understand test results, and scope tasks well to get good results.
Budget-conscious technical teams usually start with OpenHands (free, private). Teams that want managed autonomy and can spend $500+/month lean toward Devin. Teams with mixed research-plus-coding needs often get the most value from Manus.
Conclusion
There is no single winner in OpenHands vs Devin vs Manus — only the right fit. OpenHands gives developers free, private, customizable autonomy. Devin gives teams the most hands-off software engineering experience money can buy. Manus gives everyone a versatile agent for the messy mix of research, data, and building that real work involves.
