How these alternatives were chosen
Tools Codesandbox names as alternatives that this directory also publishes, followed by others in Devtool. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
Codesandbox also lists GitHub Codespaces, Gitpod, AWS Cloud9, DigitalOcean App Platform as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
