How much does it cost to extend a Base44 app?

We bill at $70/hour with a minimum of 5 prepaid hours. For larger projects we provide a fixed quote after the free assessment so you know the total cost before committing. Feature additions typically take 5–15 hours; full completion engagements run 15–40 hours depending on scope.

Where Base44 Hits Its Ceiling

Base44 is genuinely fast for building internal tools and MVPs. But every platform has hard limits — and Base44's tend to appear exactly when your product starts to grow.

Vendor Lock-In by Design

Base44 runs on a proprietary database and closed hosting. Your app isn't portable by default. If you need to migrate, extend, or self-host, you're working against the platform's architecture — not with it.

Scaling Ceiling Around 100 Users

Base44 apps typically hit performance degradation above ~100 concurrent users. For internal tools this is fine. For a product with real growth, it's a hard ceiling you'll hit sooner than expected.

Limited Custom Integrations

Base44 covers the most common integrations. Anything custom — a specific payment gateway, a proprietary internal system, a niche API — requires code that Base44's editor can't generate correctly.

Bug Loops That Burn Credits

When Base44's AI generates broken output and you keep prompting for a fix, you're burning credits on the same loop. Once stuck, the only path forward is editing the underlying code directly.

Support Queue Delays

Base44's support queue means waiting hours or days for fixes when your product is broken. If you're running a live app with real users, that wait time is not acceptable.

Platform Uncertainty Post-Acquisition

Base44 was acquired by Wix in June 2025. Platform consolidations bring changes to pricing, features, and roadmap. If you're building something long-term, vendor dependence is a risk worth managing now.

Hit any of these walls? We help you get past them.

What We Do With Your Base44 App

We extend what Base44 built, not replace it. The work you've done is the foundation — we add what the platform can't.

Platform Audit

We assess your Base44 app: what's working, what's hitting platform limits, and where custom code is needed to go further.

Custom Integrations

Connect your Base44 app to any external system: payment processors, internal APIs, communication tools, and data sources the editor doesn't support.

Scaling Solutions

Optimize performance beyond Base44's default limits. Query optimisation, caching, or a targeted migration for the components that need to scale.

Feature Completion

Build the features that Base44's AI couldn't generate correctly: complex business logic, custom workflows, and advanced data operations.

How We Work With Your Base44 App

Three steps. You know what it takes before committing to anything.

1

Free Discovery Call

30 minutes. You show us the app and describe what you need beyond what Base44 provides. We tell you honestly what's possible, how long it takes, and what it costs.

2

Assessment & Plan

Within 48 hours you get a written plan: exactly what we'll build or fix, what won't need touching, and the projected timeline. You approve before work begins.

3

Build & Deliver

We build on top of your Base44 app, test everything, and hand over working code with documentation. Your Base44 setup stays intact — we add to it, not replace it.

FinTech

Nordic FinTech — Stuck for Months, Live in 3 Weeks

A FinTech team had been stuck on their AI-generated app for months before reaching out. We took over the project, assessed what was blocking them, and had them live within 3 weeks.

Health Tech

Milano Health — Critical Features Added, Launched to Production

A health technology team had an app at 80% but couldn't get the remaining critical functionality working. We built what the platform couldn't generate and took the project to a full production launch.

Frequently Asked Questions

Yes. We extend Base44 apps with custom backend logic, third-party API integrations, and functionality that Base44's editor doesn't support natively — without replacing the Base44 frontend you've already built.

Base44 apps typically start experiencing performance issues above ~100 concurrent users due to the platform's shared infrastructure. We diagnose the bottlenecks and implement solutions: query optimization, caching layers, or a migration to infrastructure that scales with your growth.

Yes, though it requires careful planning. Base44 uses a proprietary database and closed hosting, which makes portability low by design. We assess your specific app and give you an honest picture of what migration involves and whether it makes sense for your use case.

We bill at $70/hour with a minimum of 5 prepaid hours. For larger projects we provide a fixed quote after the free assessment. Feature additions typically take 5–15 hours; full completion engagements run 15–40 hours depending on scope.

Base44 was acquired by Wix in June 2025. Platform consolidations can bring changes to pricing, features, and support. If you're concerned about platform continuity, we can assess your migration options and help you build a version of your app that isn't dependent on a single vendor.

Yes. When Base44's AI gets stuck generating the same broken output, the only path forward is working directly with the underlying code. We debug the root cause and fix it without burning more credits on the same loop.

Small feature additions: 3–7 days. Completing an app that is 70–80% done: 2–4 weeks. Complex apps with multiple integrations: 4–8 weeks. You get a realistic estimate after the free discovery call.
