Bubble
Bubble is the veteran of this group — a full visual development platform running since 2012 that lets you build genuinely complex web apps (marketplaces, SaaS, internal tools) without code, using a drag-and-drop editor backed by a real database and workflow engine. Its newer AI features can scaffold an app from a prompt, but the heart of Bubble is the visual builder, not the prompt.
That makes it the most capable tool here for ambitious apps — there's very little a determined builder can't ship on Bubble — and also the steepest to learn. Where Lovable or Hostinger Horizons try to hand you a finished thing, Bubble hands you a powerful canvas and expects you to design the logic. It rewards the time you put in.
The catch is the Workload-Unit pricing. On top of the monthly subscription, your app consumes WUs on every action, and an inefficiently built app can burn through its allowance and force a higher tier. Budget for WUs as your traffic grows, and note that Bubble is a managed platform — you build on its infrastructure rather than exporting standalone code.

Bubble pricing (2026)
Subscription + Workload Units (WU): each plan includes a monthly WU allowance, and every database query, workflow and API call consumes WUs — busy or inefficient apps can exceed the allowance and need a higher tier or top-ups.
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Build and test on a bubbleapps.io subdomain, 3 trial apps, no custom domain or launch |
| Starter | $29/mo | Annual billing · 175K workload units/mo, custom domain, recurring workflows |
| Growth | $119/mo | Annual · 250K WU, premium version control, 2FA, 2 editors, 10 branches |
| Team | $349/mo | Annual · 500K WU, team roles, 5 editors |
| Enterprise | Custom | SSO, dedicated support, custom WU and scale |
Prices billed monthly unless noted; annual billing usually saves ~20%. Verify current pricing on Bubble's site — plans change often.
Bubble: best for complex no-code apps
Bubble is the most powerful tool here for building a genuinely complex app without code — if you can invest in the learning curve, almost nothing is out of reach. Just budget for Workload Units as you scale and accept the platform lock-in; for a quick prompt-to-app result, lighter tools like Lovable or Hostinger Horizons get you there faster.
