What our research says

Base44

Base44 is one of the faster routes from an idea to a working app with login, database and hosting included, which suits non-developers and small teams. Credits are consumed by every AI message, so the monthly price matters less than how many iterations your app needs.

Pros

  • Backend, database, authentication, hosting and payments are built in
  • Free plan covers up to 5 apps for experimenting
  • In-app code edits and GitHub integration on paid tiers
  • Choice of AI model on higher plans

Cons

  • Credits per month are small on the lower plans, so long builds can run out
  • Headline paid prices assume annual billing
  • GitHub integration and model selection are not on the Starter plan

OnSpace.AI

OnSpace.AI covers more of the stack than a typical prototype builder, since payments and a backend are included rather than bolted on later. The credit system means real usage costs more than the headline monthly price once an app needs more than light daily use. GitHub export is a genuine escape hatch if you outgrow the platform.

Pros

  • Built-in Stripe payments and managed backend, not just UI generation
  • Supports iOS, Android, and web targets from one project
  • Code export to GitHub avoids full platform lock-in

Cons

  • Free tier is capped at 500 credits a day and 2,000 a month
  • Company name and country of registration are not published

Choose OnSpace.AI if you need

  • Builders who want payments and a backend without wiring them up separately
