OpenHands
The open-source autonomous software agent — SWE-bench top performer at 77.6%.
OpenHands (formerly OpenDevin) is the leading open-source autonomous coding agent from All Hands AI. Each task runs in an isolated Docker sandbox with a full shell, browser, and editor — the agent writes code, runs tests, browses the web, and interacts with APIs end-to-end. Available as a Software Agent SDK, CLI, self-hosted GUI, or managed Cloud service. Consistently ranked #1 on SWE-bench Verified at 77.6% resolution rate.
+ Pros
- Top SWE-bench Verified performance — 77.6% resolution rate on real GitHub issues
- Full Docker sandbox isolation — safe to run untrusted or destructive operations
- Four product surfaces: SDK, CLI, Cloud, Enterprise — maximum flexibility for any workflow
- OpenHands LM: purpose-built fine-tuned model for software engineering trajectories
- Pay-per-task Cloud pricing with no subscription required
- Enterprise features: RBAC, audit logs, cost control, VPC self-hosting
- Integrates with GitHub, GitLab, Slack, Jira, Linear, Azure DevOps
− Cons
- Self-hosting requires Docker and infrastructure knowledge
- No dedicated IDE extension — less integrated than Cursor or Copilot
- Task latency can be high for complex multi-step jobs
- Cloud tasks charged per run — costs can accumulate on large or retried tasks
- CLI now in separate repo — adds friction for some workflows

Introduction
OpenHands launched as OpenDevin in March 2024 and is All Hands AI's open-source autonomous coding agent. Each task runs inside an isolated Docker container with a full shell, browser, code editor, and IPython kernel. The agent uses that environment to install packages, run tests, browse documentation, and interact with external APIs — all without touching the host machine. The project has grown to over 74,000 GitHub stars and raised $18.8M in Series A funding (following a $5M seed round).
In late 2024, OpenDevin rebranded to OpenHands and restructured into a multi-product ecosystem. It started as a single open-source application and grew into a Software Agent SDK, a standalone CLI, a local GUI, a managed Cloud service, and an Enterprise offering for VPC self-hosting. The project ranks at the top of SWE-bench Verified — currently at 77.6% resolution rate (achieved with Claude Opus 4.5).
Key Features
- Docker sandbox isolation: each task runs in a fresh container with shell, browser, editor, and IPython — fully isolated from the host system
- SWE-bench top performer: 77.6% resolution rate on Verified, the highest among open-source agents
- Model-agnostic: supports Claude, GPT, Gemini, local models via LiteLLM, plus the proprietary OpenHands LM fine-tuned for software engineering
- Autonomous PR creation: point OpenHands at a GitHub issue and it clones the repo, develops a fix, runs tests, and opens a pull request
- Browser inside sandbox: the agent can browse documentation, read web pages, and interact with web-based tools as part of its workflow
- Micro-agents and skills system: composable sub-agents for specific tasks like debugging, refactoring, or dependency management. Users can define custom micro-agents using the Skills API — small, focused agents that handle specific tasks like dependency auditing or test generation.
- GitHub/GitLab integration: auto-receive and resolve issues, with support for Azure DevOps, Bitbucket Datacenter, and Forgejo
- KVM acceleration: v1.7.0 adds hardware-accelerated virtualization for faster sandbox startup
Product Ecosystem
OpenHands offers four products covering everything from library-level agent building to enterprise deployment.
Software Agent SDK is a composable Python library for defining agents in code. Developers import the SDK, configure tool sets and model providers, and build custom agents for their specific workflows. This is the same SDK that powers all other OpenHands surfaces.
OpenHands CLI lives in a separate repository and provides a terminal-based agent experience. It supports OAuth 2.0 Device Flow for authentication and is built for developers who prefer using the command line over a browser UI.
Local GUI is a React SPA backed by a REST API that runs on the developer's machine. It provides the familiar OpenHands web interface for self-hosted use — point it at a Docker daemon and start assigning tasks.
OpenHands Cloud is the managed service at app.all-hands.dev . Users pay per task (roughly $0.10 to $2 depending on the model) with no subscription required. Cloud integrates with Slack, Jira, and Linear for workflow automation, and includes RBAC for team access control.
OpenHands Enterprise is a source-available offering for self-hosting inside a customer's VPC via Kubernetes. It includes audit logs, cost controls, extended support, and SLA guarantees.
Performance & Benchmarks
OpenHands holds a 77.6% resolution rate on SWE-bench Verified — the highest among open-source agents.
Enterprise adoption spans major technology companies: TikTok, VMware, Roche, Amazon, C3 AI, Netflix, Mastercard, Red Hat, MongoDB, Apple, NVIDIA, and Google are all listed as users.
OpenHands LM, a fine-tuned model trained specifically on software engineering trajectories, is available through Cloud and can also be used with self-hosted deployments. It improves task completion rates on both SWE-bench and real-world GitHub issues compared to general-purpose models.
Recent Updates
OpenHands has shipped updates rapidly since its v1.0.0 rewrite in December 2025. Notable additions include the Planning agent for multi-step workflows (v1.5.0), custom event hooks (v1.6.0), and KVM-accelerated sandbox execution (v1.7.0). The full changelog is available in the version logs.

Signature Snippet
Point OpenHands at a GitHub issue: "Fix the race condition in the async task queue — see issue #412." OpenHands spins up a Docker sandbox, clones the repo, reads the issue and relevant code, writes a fix, runs the test suite, resolves failures, and opens a pull request with a detailed explanation — without any human intervention.More in this Space
