Alternatives / GitHub Codespaces
Looking for an open source GitHub Codespaces alternative? We found one open source platform: Coder, a self-hosted platform for cloud development environments defined as code. It runs on your own infrastructure, and some enterprise features are under a separate license.

We looked for open-source platforms that cover Codespaces' core: starting a ready-to-code remote development environment for a repository. We verified the project's license, recent activity, stars, and self-hosting in its repository. Only one project met these criteria, and it is a self-hosted platform rather than a hosted service. See our methodology for the full criteria.
Coder provisions cloud development environments on infrastructure you control, such as Kubernetes, VMs, or a cloud provider, defined with Terraform. You need to operate and secure it, unlike Codespaces, which GitHub runs for you.
Coder works with VS Code, JetBrains IDEs, and SSH, and offers features for cost control, security, and SSO. It is Git-host independent, so it can serve repositories on GitHub, GitLab, or your own server.
Coder's main license is AGPL-3.0, but code in its enterprise directory is under a separate Coder enterprise license, so some advanced features need a paid plan. Claims about certifications and performance on its site are the vendor's own.
Coder's repository had commits within days of this update and has about 17,000 stars.
GitHub Codespaces is a proprietary service billed by compute and storage hours, tied to GitHub and Azure infrastructure, with limited control over where code and environments run. A self-hosted alternative lets you run environments on your own cloud or servers, control costs and data location, and use any Git host, at the cost of operating the platform yourself.
Coder is a self-hosted development platform that provisions remote development environments defined as code, on infrastructure you control, with support for VS Code, JetBrains, and SSH, plus cost controls, security features, and SSO. The main license is AGPL-3.0, and code in the enterprise directory is under a separate Coder enterprise license.
Pricing: Free to self-host the open-source parts; enterprise features are paid.
| Alternative | Type | License | Self-hosted | IDE support |
|---|---|---|---|---|
| Coder | Cloud dev environments | AGPL-3.0 + enterprise directory | Yes | VS Code, JetBrains, SSH |
Want cloud dev environments on your own infrastructure
Coder provisions environments defined as code on Kubernetes, VMs, or a cloud provider you control.
Want to use any Git host, not only GitHub
Coder is independent of the Git host, so it works with GitHub, GitLab, or a private server.
Need SSO and cost controls for a team
Coder offers SSO, security features, and cost controls, with some advanced features in its enterprise directory.
