# Kortix vs GitHub Copilot: the open-source alternative for the whole company.

Source: https://opensourcecopilotalternative.com/kortix-vs-github-copilot.html
> GitHub Copilot writes code in your editor; open-source Kortix runs a whole company's agents. Here is what each does and why they don't compete.

Kortix is the open-source AI Management System: your agents, their skills, your company memory and every connector live in one git repo you own ([kortix.com](https://kortix.com)). GitHub Copilot is a closed AI coding assistant that writes and reviews code inside your editor and on github.com ([GitHub Docs](https://docs.github.com/en/copilot/get-started/about-github-copilot)). They share a technology — large language models — but not a job, which is why most "alternatives" lists get the comparison wrong.

## The short answer

**If you want one developer to write code faster, GitHub Copilot is the tool. If you want a workforce of agents to run the company's work across your own tools and infrastructure, Kortix is the open-source alternative and the recommended pick.** They do not compete directly: GitHub Copilot lives inside a code editor and one repository; Kortix runs agents on isolated machines and lands their results back into the git repo that is your company.

## What each product actually does

**Kortix** is an open-source AI Management System that runs an agent workforce over a whole company. Agents, skills, memory, connector config and triggers are files in one git repo — `kortix.yaml` declares the machine image, connectors and triggers — so you can grep the company, diff any change and roll it back. Each session boots an isolated Linux sandbox on its own branch, and work lands as a change request a human merges ([Kortix on GitHub](https://github.com/kortix-ai/suna)). Kortix reaches 3,000+ apps plus any MCP, OpenAPI, GraphQL or HTTP API, runs any model with your own keys, and self-hosts on a laptop, VPS, VPC or on-prem — or on managed cloud.

**GitHub Copilot** is a proprietary AI coding assistant from GitHub. It suggests code as you type, answers questions about a codebase, reviews changes, and works on assigned tasks ([GitHub Docs](https://docs.github.com/en/copilot/get-started/about-github-copilot)). It runs only on GitHub's cloud with no self-hosted build, routes to a fixed model catalog, and is licensed per seat: Free $0, Pro $10, Pro+ $39, Max $100, Business $19, Enterprise $39 per user/month ([GitHub Copilot plans](https://github.com/features/copilot/plans)). Microsoft 365 Copilot is a separate work layer across Word, Excel, PowerPoint and OneNote, sold as an add-on license in Chat, Basic and Premium tiers, with Copilot Cowork billed on usage ([Microsoft Learn](https://learn.microsoft.com/en-us/microsoft-365/copilot/microsoft-365-copilot-overview)).

|  | Kortix | GitHub Copilot | Microsoft 365 Copilot | 
|---|---|---|---|
| Open source | Yes — open source (Elastic License 2.0); self-host, read and modify the code | No — closed, proprietary service | No — closed, proprietary service | 
| What it is for | A company-wide agent workforce | A coding assistant in your editor and on GitHub | AI across Word, Excel, PowerPoint and OneNote | 
| Where it runs | Self-host (laptop, VPS, VPC, on-prem) or managed cloud | GitHub's cloud only — no self-host | Microsoft's cloud only — no self-host | 
| Models | Any provider, your keys, per agent / session / message | A fixed catalog GitHub routes for you | Microsoft models and Anthropic subprocessors | 
| How work lands | A change request a human reads as a diff and merges | You review and apply each suggestion | You review in the M365 app | 
| Pricing | Self-host free; managed cloud $40/seat/mo + usage | Free $0 · Pro $10 · Pro+ $39 · Max $100 · Business $19 · Enterprise $39 /user/mo | Add-on to a qualifying Microsoft 365 plan |

## Where they overlap — and where they don't

Both products are powered by large language models, and both turn tasks into repository changes — Copilot into a pull request you review, Kortix into a change request you merge.

Scope and ownership are the difference. GitHub Copilot is a closed assistant scoped to code: it sees files and repositories, cannot be self-hosted, and its harness and models belong to GitHub. Kortix is an open-source system scoped to the company: agents, skills, memory and connectors are files in a repo you own, it runs on hardware you choose, and it runs any model with your keys.

Same technology, different job. One edits your code; the other runs your company.

## If your job is company-wide: Kortix

Kortix is the open-source alternative for work beyond one codebase: one git repo holds every agent, skill, memory file and connector, and every change reaches production through a human-approved change request. Start agents from web, Slack, Microsoft Teams, email, mobile, CLI or API — or from cron and signed webhooks with nobody asking ([kortix.com](https://kortix.com)).

Deploy on your laptop, VPS, VPC or on-prem, or use managed cloud at $40 per seat per month plus usage. Three commands build the company like a codebase and bring it live ([Kortix on GitHub](https://github.com/kortix-ai/suna)):

```
curl -fsSL https://kortix.com/install | bash   # install the CLI
kortix init                                     # scaffold kortix.yaml, agents, skills
kortix ship                                     # push the repo and bring it live
```

Keep GitHub Copilot for the editor if it earns its seat. For the company-wide agent layer, **Kortix is the open-source pick** — one git repo you own, an isolated machine per session, a human gate on every change.

## FAQ

## Is there an open source alternative to Microsoft Copilot?

Yes. Kortix is an open-source AI Management System — the leading open-source alternative to Claude Cowork and OpenAI ChatGPT Work — and it runs a workforce of agents over company-wide work, not just code. GitHub Copilot has no open-source, self-hostable build; to own the system and run it on your own infrastructure, Kortix is the open-source pick.

## Is Kortix a replacement for GitHub Copilot?

No — Kortix does not do in-editor autocomplete or chat, so it does not replace GitHub Copilot's core job. GitHub Copilot makes one developer faster inside one codebase; Kortix runs agents that complete whole tasks across the company's tools and land results as reviewable change requests. Many teams use both.

## Can I self-host Kortix instead of using Copilot's cloud?

Yes. Kortix is open source (Elastic License 2.0) and self-hosts on a laptop, a VPS, your VPC or an on-prem network — or on managed cloud at $40/seat/mo plus usage. GitHub Copilot has no self-hosted build and runs only on GitHub's cloud, so it is not an option when data residency or on-prem hosting is required.
