These four get lined up as rivals, as if you are meant to crown one and walk away. That framing misses the point. They are not four answers to the same question. They are four answers to a question you have not asked yet: where do you actually want to work? In a terminal, inside your editor, in a plain app window, or in a sandbox that runs without you watching?
Answer that, and the choice mostly makes itself. We run all four in the studio for different jobs. Here is the honest read.
The four contenders, in one line each
- Aider is the terminal-first one: a mature, git-aware pair programmer you drive from the shell. It proposes, you approve, it commits.
- Cline is the VS Code one: the same agentic loop inside your editor, where every file open and every diff is visible in a side panel.
- OpenCode is the app one: a native desktop application you double-click, no terminal and no editor required.
- OpenHands is the sandbox one: an autonomous engineer running in a Docker container that can build whole tasks end to end with minimal supervision.
The real axis: where you work, and how much it does without you
Two questions sit underneath all the feature lists.
The first is location. Aider lives in your terminal. Cline lives in VS Code. OpenCode lives in its own app window. OpenHands lives in a browser tab pointed at a Docker container. None of these is better in the abstract. They are better for different people in different chairs.
The second is autonomy, and it is the one most comparisons skip. Aider and Cline are collaborative by design: they propose a change, you approve it, then they act. That “propose then approve” rhythm is a feature, not a limitation, because it keeps you in the loop on every edit. OpenCode follows the same approval-based shape. OpenHands is the outlier: it runs in a sandbox and can complete an entire multi-step task with very little supervision. More power, less oversight, and a heavier setup to match.
Get clear on those two answers, and the rest is detail.
How they compare, dimension by dimension
Where you work. Aider is a terminal you drive. Cline is a panel inside VS Code. OpenCode is a normal app on your Dock. OpenHands is a web UI in front of a container. If “I do not want to learn another shell tool” describes you, Aider drops off the list and OpenCode moves to the front. If you already live in VS Code, Cline is the path of least resistance.
Setup cost. OpenCode is the lightest: download the app, pick a provider, type. Cline is nearly as easy if you already run VS Code, since it is just an extension. Aider is one pip install and a git repo, comfortable if the terminal is home. OpenHands is the heaviest by a wide margin: it needs Docker Desktop with real memory allocated, and a sandbox image alongside the main one. That setup buys autonomy, but it is setup.
Autonomy. OpenHands sits at the autonomous end, built to run tasks to completion in its sandbox. Aider, Cline, and OpenCode sit at the supervised end, asking before they act. This is the cleanest line between the four: three collaborators and one autonomous worker.
Visibility. Cline makes the agent’s work the most watchable. It opens files in tabs, shows diffs with approve and reject buttons, and surfaces every command before it runs. That visibility is the whole reason it exists, and it is why it shows so well in a demo. Aider shows its work too, but as terminal output rather than a live editor. OpenHands shows a file pane and a terminal pane as it works. OpenCode shows the work in its app window.
Git. Aider is the most git-native of the group. It expects a repo, and it commits changes with clean, descriptive messages by default. If your mental model of “AI did work” is “there is now a tidy commit in the log,” Aider fits that instinct best.
Privacy. All four are model-agnostic and can point at a local model through Ollama, which keeps your code on your machine. One caution worth naming: OpenHands mounts the Docker socket, so its container can spawn other containers on your host. That is a real security consideration, and a reason not to feed it untrusted prompts. The other three carry no comparable footgun.
The model is the ceiling. This is true for all four and worth saying plainly. A weak model makes a weak agent regardless of the wrapper. The agentic loop, read then propose then edit, exposes a model’s limits fast, especially in Cline and OpenHands where steps stack up. Locally, reach for a strong coder model in the 32B class. For the hardest tasks, a frontier cloud model still pulls ahead, and any of these four can be pointed at one for a single job.
Who should pick what
Pick Aider if you live in the terminal, you work in git, and you want a mature, precise pair programmer that commits its work cleanly. It is the production developer’s choice when in-editor completion is not enough and full autonomy is too much.
Pick Cline if you live in VS Code and you want to see the agent work. Watching files open and diffs appear, approving each step, is the value. It is also the friendliest to show a client or a less terminal-comfortable teammate.
Pick OpenCode if you want a coding agent in a normal app window, with no terminal, no editor, and no Docker between you and the work. It is the only one of the four that ships as a double-click desktop app, and that alone reframes the category for people who do not live in a shell.
Pick OpenHands if you want maximum autonomy and the wow of watching an AI build a working app from a single prompt, and you are willing to run Docker to get it. It is the exploration tool and the demo tool, not the careful daily driver.
What we run, and why
All four, deliberately, for different jobs.
Aider is our terminal-first daily driver for real developer work: refactors, scripting, custom tools, and yes, maintaining the Atlas itself. The git-aware commits and the architect-then-code split keep our thinking honest about what is about to change.
Cline comes out when we want to watch an agent work, or when someone less at home in a terminal wants to take part. The visibility is the reason.
OpenCode is the one we hand to people who will never open a terminal. Pointed at Ollama with a local model, it gives the privacy story of a terminal agent with the approachability of a normal app. For “I just want the thing to open,” it is the answer.
OpenHands is our wow-demo tool. When someone needs to see what autonomous AI looks like, nothing else in the Atlas lands as hard. For day-to-day precision we still reach for Aider or Cline, but for “watch it build something from scratch,” OpenHands wins the room.
That is the honest hierarchy. Aider is the most precise, Cline the most watchable, OpenCode the most approachable, and OpenHands the most autonomous. We do not tell you which to use. You watch the work, you make your own call. But start by answering where you want to work, and most of the decision is already made.
Curious about these things. You should be too.
Harness your curiosity.
