Cline vs OpenHands 2026: Which Open-Source AI Coding Agent Should You Run?

This article was originally published on aicoderscope.com

Both tools are open-source, both let you bring your own API keys, and both can autonomously edit files, run terminal commands, and ship features. Beyond those surface similarities, Cline and OpenHands solve fundamentally different problems. Picking the wrong one means either babysitting an agent that keeps interrupting you, or fighting a Docker stack when you just wanted tab-complete plus plan mode.

Here's what separates them.

The core architectural split

Cline lives inside your editor. It runs as a VS Code extension (and JetBrains plugin, and inside Cursor, Windsurf, Zed, Neovim, and a macOS/Linux CLI preview). You interact with it in a sidebar. Every file edit, terminal command, and browser action surfaces for your approval before it executes — unless you flip Auto-Approve, which you can do per-action-type or globally. The Cline review covers this approval loop in detail.

OpenHands lives inside a Docker container. The agent gets a sandboxed environment — its own shell, file system, and browser — and works autonomously until the task is done. You give it a task description, it plans and executes, and you check the result. There is no sidebar. The human-in-the-loop cadence is task-start and task-review, not step-by-step. The OpenHands review covers the self-hosting gotchas in detail.

That difference cascades through everything else: setup complexity, cost model, where each tool wins, and who should actually use it.

Setup: what it actually takes

Cline takes about four minutes. Install the VS Code extension (3.85M+ installs on the VS Code Marketplace alone as of v3.85.0, released May 25, 2026), paste your Anthropic, OpenAI, or OpenRouter API key, and you're coding. No Docker, no port configuration, no version-matching nightmares. The Cline SDK v2 — open-sourced in May 2026 — powers durable, portable sessions that can now survive an IDE restart and even migrate across surfaces (VS Code to JetBrains to CLI without losing state).

OpenHands requires Docker. Not Docker Desktop optional-but-recommended — Docker socket required. The setup command is roughly:

docker pull docker.all-hands.dev/all-hands-ai/runtime:1.7.0-nikolaik
docker run -it \
  -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:1.7.0-nikolaik \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -p 3000:3000 \
  docker.all-hands.dev/all-hands-ai/openhands:1.7.0

Two known failure modes: the Docker socket mount (/var/run/docker.sock) is required — without it, the controller cannot spawn sandbox containers and the agent loop fails immediately. The SANDBOX_RUNTIME_CONTAINER_IMAGE version must match the openhands image version. Running openhands:1.7.0 with runtime:1.6.0 produces a cryptic container start failure. If you're not running Linux or have a corporate Docker policy, this will eat an hour.

OpenHands Cloud sidesteps this entirely — you log in and run at www.openhands.dev without any local Docker. The free tier gives you 10 conversations per day.

Pricing side by side

Plan	Cline	OpenHands
Free	Open Source (unlimited, BYOK)	Cloud Individual (10 conv/day, BYOK or MiniMax model)
Solo pro	—	Cloud Pro: $20/mo (BYOK, unlimited conversations)
Team	Teams: $20/user/mo (first 10 seats always free)	Cloud Growth: $500/mo (unlimited users, RBAC)
Enterprise	Custom (VPC, SSO, SCIM, audit logs)	Custom (VPC/K8s, SAML/SSO, Large Codebase SDK)
Inference cost	You pay your provider directly (zero markup)	You pay your provider directly (zero markup)

The pricing symmetry hides a real difference at the team level. Cline Teams at $20/user/mo scales linearly; a 20-person team pays $400/mo for the governance layer on top of their provider bills. OpenHands Cloud Growth at $500/mo is a flat rate regardless of team size — a better deal past roughly 25 users, a worse deal below that.

Neither platform marks up your LLM usage. If you send 10 million tokens through Claude Sonnet 4.6 this month, you pay Anthropic's published rate: $3 per million input, $15 per million output. The platform fee (if any) is purely for the scaffolding, integrations, and governance.

For individuals, both effectively start free. Cline's open-source tier has no conversation limits — just the API bill you're already paying. OpenHands Cloud Individual gives you 10 free conversations per day, which covers most evaluation use cases.

What each does well

Cline: interactive, high-trust IDE work

Cline's strength is the tight human-in-the-loop loop. The Plan/Act separation is genuine: Plan mode is non-destructive (no file changes, just reasoning), Act mode executes with per-step approval visible in your editor sidebar. For a refactor touching 30+ files across a TypeScript monorepo, you can review each change before it's written, catch the wrong abstraction at step 3 instead of step 25, and flip back to Plan when the approach needs rethinking.

The SDK v2's multi-agent support is now production-grade — a coordinator agent can delegate to specialist sub-agents, each with their own tools and context, and the agent team shares state via the same runtime. For complex tasks that benefit from parallel exploration (e.g., "write tests for all 80 functions in this module while I keep coding"), this matters.

Spend limits (daily/monthly caps added in v3.78) prevent the runaway-agent problem that made early agentic tools expensive. Setting a $15/day cap on Anthropic API spend and getting a UI warning when it's hit is a meaningful safety net.

The platform breadth is hard to match: VS Code, JetBrains (full family: IntelliJ, PyCharm, WebStorm, GoLand), Cursor, Windsurf, Zed, and Neovim. If your team isn't standardized on one IDE, Cline runs everywhere. Supports 30+ LLM providers including Anthropic, OpenAI, Google Gemini, AWS Bedrock, Azure OpenAI, OpenRouter, DeepSeek, Cerebras, Groq, xAI, Ollama, and LM Studio — the full BYOK menu.

OpenHands: autonomous, long-horizon tasks

OpenHands is built for the scenario where you hand off a task and come back to a finished pull request. The Docker sandbox gives the agent a fully isolated environment — it can install packages, run tests, browse documentation, and commit code without touching your local machine state. This makes it genuinely suitable for "resolve this GitHub issue" workflows where you don't want to babysit every step.

v1.7.0's SWE-bench Verified score is 77.6% on the V0 harness (72.8% on the more conservative V1 SDK harness using Claude Sonnet 4.5). That's one of the highest reported scores for an open-source autonomous agent. Real-world performance on your codebase will vary — SWE-bench issues are curated and well-specified, not representative of ambiguous internal tickets — but it's a meaningful signal.

Planning Mode (beta since v1.6.0, March 2026) generates a PLAN.md file before touching code, asking clarifying questions on vague prompts. It's the OpenHands answer to Cline's Plan/Act separation — except that in OpenHands, planning and execution are still modal toggles rather than a conversation-native switch.

The Agent Control Plane (Enterprise, launched May 6, 2026) adds centralized workflow management, least-privilege RBAC, cost tracking per workflow, and isolated sandboxes for each agent run. For security-conscious enterprises running dozens of agents across repositories, this is the missing layer that individual agent tools lack.
