Builddu vs Base44
An AI app builder with an integrated backend, database and user management, billed in message and integration credits.
| Builddu | Base44 | |
|---|---|---|
| Time to a working app | not measured against Base44 (as of 21 September 2026) | no measured build time published (as of 21 September 2026) |
What Base44 advertises: “the AI generates a working app — complete with design, logic, and a backend — in minutes” (base44.com, read 21 September 2026) “you can ship your first app or website in an afternoon” (base44.com/pricing, read 21 September 2026). No measured figure is published. | ||
| Backend | Full-stack: every project ships with server-side code, not a static front end. | Integrated backend and database system, included in every plan. |
| Database | Managed database included in every project, with no setup step. | Included in every plan, as part of the integrated backend. |
| Authentication | The build agent is instructed to generate sign-up, login and sessions. Observed in builds, not guaranteed. | Authentication and user management, included in every plan. |
| Who owns the code | You own what you build — our terms say so — and the full source can be pushed to a GitHub repository you control. | “You own everything you build on Base44: your code, your data, your users.” Two-way GitHub sync exports the full source to your own repo; GitHub integration is listed on Builder and above. |
| Deployment | One click to production. Publishing costs 1 credit. | Apps run on production infrastructure rather than a sandbox. |
| Custom domains | Connect your own domain to a published app. | Connect a domain on Starter and above. A free domain for the first year from Builder up, on yearly billing only. Not on the free tier. |
| Pricing | Starter $20/month for 100 credits, Pro $49/month for 300, Business $99/month for 600. Top-up: 100 credits for $19. | Free $0 (25 message + 100 integration credits/mo). Paid, billed annually: Starter $16, Builder $40, Pro $80, Elite $160 per month, from 100 to 1,200 message credits. |
The pricing row squeezes Base44’s plans into a single line. Our full breakdown of Base44’s pricing sets out every plan and what a credit actually buys.
What Base44 is good at
- Internal tools where user accounts and permissions matter from day one
- Teams that want the source in their own GitHub repo without leaving the builder
- Projects that outgrow a prototype and need to run on real infrastructure
Where Base44 is the better choice
- Their public pricing page documents backend, database, auth, domains and code export outright — ours does not exist yet.
- Two-way GitHub sync is documented on their own pricing page, on Builder and above.
- A free tier you can keep using every month, where our free credits are a trial.
- A wider plan ladder, from $16 to $160, so cost tracks usage more gradually than our three tiers.
Where we fall short
Our own weaknesses, in our own words. They apply whichever product you compare us with.
- We are newer and smaller than every product on this list, with a shorter track record behind the apps we generate.
- Deep app analytics, integrations, and version history aren't built yet — they're planned, not available today.
- We do not have the community, templates and tutorials that the larger platforms have accumulated.
- Build times can vary — during busier periods a build may take longer than usual. We're working to make wait times more predictable.
Which one should you use?
It depends on what you are building and who you are. Here is our honest read.
If the other name on your shortlist is Lovable rather than us, we have weighed Base44 against Lovable as well, with Builddu kept out of the side-by-side.
A founder who needs logins and roles on day one
Base44 documents authentication and user management on every plan, on its own pricing page; our build agent is instructed to generate sign-up and login, observed in builds but not guaranteed.
A developer who wants the code in their own repo continuously
Base44 documents two-way GitHub sync on its pricing page, on Builder and above; ours has not been verified as a full round trip.
Weighing more than one builder? We also keep our list of Base44 alternatives, which sets several of them side by side rather than just us and them.

The fastest way to settle a comparison is to describe the same app to both and see what comes back.
