AWS Cloud9 vs GitHub Codespaces

AWS Cloud9 is a browser-based IDE for writing, running, and debugging code. It combines an editor, debugger, and terminal and supports over 40 programming languages, including JavaScript, Python, PHP, Ruby, Go, and C++. Users can create environments on new EC2 instances or connect existing Linux servers over SSH. EC2 environments include Git, Docker, language runtimes, package managers, and an AWS CLI authenticated with the logged-in user’s permissions. Cloud9 includes tools for creating, editing, running, debugging, and deploying Node.js or Python AWS Lambda functions, with AWS SAM support. IAM users in the same AWS account can collaborate on IDE and command-line sessions. Editor features include auto-completion, code folding, hinting, syntax highlighting, and more than 30 color schemes. Cloud9 has no additional service charge, but EC2 compute, EBS storage, and other AWS resources are billed at normal rates. EC2 setups create an instance and 8-GB EBS volume, and users remain responsible for patching and backups. Environments can stop automatically after the IDE closes, which may end terminal sessions.

GitHub Codespaces provides cloud development environments configured for a repository and hosted by GitHub. Repository dev container files can define a repeatable environment; users can start from a template or a branch or commit. Each codespace runs in a Docker container on a GitHub-hosted virtual machine, with machine choices from 2 cores, 8 GB RAM, and 32 GB storage to 32 cores, 128 GB RAM, and 128 GB storage. Connect through a browser, Visual Studio Code, or GitHub CLI from an internet-connected device, including an iPad. The Codespaces extension also connects a GitHub account to local Visual Studio Code. Each codespace has its own virtual machine and isolated network; connections use a TLS-encrypted tunnel and GitHub authentication, and forwarded ports are private by default. GitHub Free personal accounts include 120 compute hours and 15 GB-month of storage; Pro includes 180 hours and 20 GB-month. Usage is billed monthly, with 2-core compute at $0.18 a month and storage at $0.07 a month. Codespaces cannot be self-hosted and is unavailable for repositories owned by managed user accounts.
