In simple English
You can run your programming workspaces on a private cloud server instead of your personal computer. It lets you write code from any device without slowing it down. You set up your tools once so they stay the same everywhere you work. It costs you the price of a server and some setup time to run. The base software is free, but large teams pay for extra support and features.
What it is
Coder (a self-hosted platform for cloud development environments and AI coding agents) manages virtual developer workspaces on your own servers. Workspaces are defined using Terraform (a tool for building and managing cloud infrastructure using code) and connected through a secure WireGuard (a fast and simple way to create encrypted virtual private networks) tunnel.
What it is good for
Solo builders who want to code from an iPad or an old laptop while keeping all heavy tasks on a powerful cloud server. It removes the pain of setting up a new development machine from scratch every time.
- Access your full development setup from any computer or tablet.
- Shuts down idle workspaces automatically to save on server costs.
- Centralizes AI coding agents and model credentials securely in one place.
- Requires comfort with server administration and Terraform scripts.
- Needs a dedicated server with enough RAM to run multiple developer workspaces.
- Licenced under AGPL-3.0 (which requires sharing your modified source code if you offer it as a public service).
