The short version

  • Both are free.
  • Only Bubble lists visual app editor; only CosmosDB lists global Distribution.
  • Where Bubble falls short: apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.
  • Where CosmosDB falls short: autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used.
  • 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.

Bubble

  • Apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown
  • Complex apps can hit performance limits compared to hand-coded applications as data and workflow complexity grows
  • The visual workflow editor has a steep learning curve for genuinely complex business logic
  • Free tier cannot host apps on a custom domain, limiting it to prototyping rather than production launches

CosmosDB

  • Autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used
  • Provisioned throughput is charged in every region the account is replicated to, so multi region accounts multiply the RU bill
  • Storage charges cover data, indexes and backups in each replicated region
  • Egress out of Azure and between regions is charged, though ingress is free
  • The free allowance is one account per Azure subscription, limited to 1,000 RU/s and 25 GB
  • RU/s rates vary by region and are only shown through the pricing calculator rather than a flat published rate
