The short version

  • Couchbase is a distributed NoSQL cloud database.
  • Both are free.
  • Only CodeSandbox lists instant sandboxes; only Couchbase lists JSON Document Model.
  • Where CodeSandbox falls short: public sandboxes are visible to others by default, which is not ideal for proprietary code.
  • Where Couchbase falls short: the free tier is a single node with 8 GB of storage and forum support only.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CodeSandbox

  • 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

Couchbase

  • The free tier is a single node with 8 GB of storage and forum support only
  • Node rates are hourly and quoted as starting figures, from $0.15 an hour on Basic to $0.49 on Enterprise
  • The Developer Pro and Enterprise plans require 3 nodes, so the hourly rate multiplies before any usage
  • Backup storage is billed separately at $0.07 per GB a month, and analytics backups at $0.14
  • Support response time is a plan feature, at 8 hours on Developer Pro against 30 minutes on Enterprise
  • AI and analytics run as separately priced planes at up to $0.86 an hour per node
