Is Aider or OpenHands better for a self-hosted coding agent?

Aider runs in your terminal on your own machine and is built for one developer editing one codebase. OpenHands runs a browser control center with its own agent server on a laptop, in Docker, on a virtual machine or inside your infrastructure, and it suits a team running coding agents and automations across a few backends.

Can I use my own model and keys with Aider and OpenHands?

Yes. Aider connects to almost any LLM, including local models, and takes the key you pass at run time. OpenHands brings your own model. Kortix takes any model provider with your own keys, or the ChatGPT plan you already pay for.

What can Kortix do that OpenHands and Aider do not?

Kortix keeps a company's agents, skills, memory and connector rules in one git repo you own, and it runs any team's work, not only code, across 3,000+ apps. OpenHands and Aider are coding tools whose work ends in a change to a repository.

Do I have to replace my coding tool to use Kortix?

No. Many teams keep Aider or OpenHands for code and run Kortix for everything else. Git stays the record of work on both, so a team can move one workflow across first and leave the coding tool where it fits.

OpenHands vs Aider: choosing between two open source coding tools

OpenHands vs Aider is a real coding-agent decision, and both are open source. Kortix, the open-source AI Operating System, is the pick when the work goes past code: one repo for every team's agents, memory and connectors.

How a session becomes reviewed work

project

project (git repo + kortix.yaml)└─ session ──> cloud computer: an isolated sandbox on a branch named after the session└─ the OpenCode agent works└─ change request ──> you review & merge ──> main

From the Kortix README: a project is a repo, each session runs on its own cloud computer and branch, and its work reaches main through a change request.

What OpenHands and Aider each actually are

OpenHands is a self-hosted developer control center for coding agents and automations. Its own README describes a place to start conversations with an agent and automate everyday tasks, running locally by default and connecting to other backends such as Docker, a virtual machine, or your company infrastructure. It runs its own OpenHands agent out of the box and can also drive another agent through an agent protocol. Aider is AI pair programming in your terminal. Its README says Aider maps your whole codebase, edits it, and commits each change with a sensible message, so you diff, undo and manage the work with ordinary git.

How the interface and the unit of work differ

Aider keeps one developer in the loop inside a terminal. You run a command, name a model, and work on one codebase; Aider answers in the same prompt and writes commits as it goes. OpenHands puts a browser control center in front of coding agents so a team can run several conversations at once, each isolated, with automations that fire on a schedule or a webhook. The unit of work follows the interface: Aider's is an edit-and-commit turn in one repository, and OpenHands's is a coding conversation or an automation that ends in a code change. A job with no diff at the end has no shape in either tool.

Running them yourself: models, keys, sandboxes

Both tools run on machines you control and both leave the model bill to you. Aider connects to almost any LLM, including local models, and reads the key you pass at run time, as its quickstart shows with aider --model deepseek --api-key deepseek=<key>. OpenHands brings your own model and runs its agent server on a host you choose; its README is direct that a local install gives the agent full access to that machine's filesystem, so the host is the boundary. Kortix answers the same question in one move: run it on Kortix Cloud, in your VPC, or on-prem, with self-host free, and the whole system comes up as one Docker Compose stack. The self-hosting guide works through what the first run asks for and where each sandbox lives.

What neither does for a whole company

Both projects connect to developer tools rather than a company's systems. OpenHands automations reach Slack, GitHub and Linear; Aider works inside a git repository and a terminal. Neither keeps one place where a company's agents, skills, memory and connector rules live as files a team reviews and diffs. Kortix is the open-source AI Operating System: those pieces live in one git repo you own, and its agents cover any team's work, from code to reports and replies, across 3,000+ apps. Agent work there lands through a change request a person merges, and merge is default-deny for agents.

How to choose

Aider is the fit when the job is editing one repository and you want a terminal pair programmer. An engineering team that wants a self-hosted control center for coding agents and automations across a few backends is well served by OpenHands. Kortix is the pick when the work leaves code, when a second team wants to build on the same agents, or when an agent has to reach a business app that is not Slack, GitHub or Linear. The wider field sits in the OpenHands alternatives comparison, the coding question in OpenHands vs Kortix and OpenHands vs OpenCode, and the Kortix blog's Kortix vs OpenHands.
