Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CodeSandbox
- Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
- Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
- Public sandboxes are visible to others by default, which is not ideal for proprietary code.
Deno
- The runtime itself is MIT licensed per the project's GitHub repository (denoland/deno LICENSE.md) with no cost, but Deno Deploy's free tier caps at 1 million requests and 15 CPU hours per month, per deno.com/deploy/pricing (Aug 2026)
- Deno Deploy Pro at $20 per month charges $2 per additional million requests and $0.05 per additional CPU hour once the included quota is exceeded, per deno.com/deploy/pricing
