An honest comparison — sources linked below

Bubble is the professional's canvas.
Kitty is the co-founder who says no.

The short answer: Bubble is the most mature no-code platform — $29/mo annual on Starter, free plan that cannot publish, workload-unit pricing with $0.30-per-1,000 overage — and it is built for complex apps and professional builders. kitty.build is a different product: a free nine-board validation that researches the live web and cites its claims, then a site on your own domain, commits in your own GitHub repo, and daily operating cycles. Bubble for depth; kitty.build for deciding what deserves depth.

What Bubble does well

  • The most capable no-code platform for complex, stateful applications — nothing else here comes close on logic depth
  • A real hiring market: you can pay someone to take over your Bubble app tomorrow
  • Battle-tested at production scale for a decade, not a 2024 startup
  • Plugin ecosystem covers integrations the AI builders would need custom code for

Where Bubble falls short

  • Workload-unit pricing is the least predictable model in this comparison — overage starts at $0.30 per 1,000 units the moment you exceed the tier
  • Steep learning curve: this is a professional tool, not a chat box
  • No code export, so the app cannot leave the platform
  • You cannot publish on the free plan, so evaluating it properly costs $29/mo

When Bubble is the better buy

For a complex, logic-heavy application that has to work for years and might one day be handed to a contractor, Bubble is the safer platform. It has a decade of production use, a deep plugin ecosystem and a real hiring market. kitty.build's generated sites and repo commits are not a substitute for a mature visual app platform, and pretending otherwise would be dishonest.

Our verdict on Bubble in 2026

Bubble is the grown-up of the no-code category: a decade of production apps, real logic depth, and a hiring market you can actually recruit from. Its costs are the least predictable of anything here — workload units meter every query, workflow and page load, and overage bills immediately — and there is no code export, so the app cannot leave. kitty.build is not a visual editor and does not try to be; it validates the idea first and then produces real code in your own GitHub repo. Choose Bubble for depth and permanence, kitty.build for judgement and ownership.

Frequently asked

Is Bubble free?
There is a free plan with 50,000 workload units a month, but you cannot publish an app on it. That makes the free tier a learning environment rather than a launch path — publishing starts at $29/mo on annual billing ($32 monthly).
Why is Bubble pricing unpredictable?
Bubble meters workload units, which are consumed by every database query, workflow, API call and page load. Traffic spikes and inefficient workflows both raise the bill, and overage starts immediately at $0.30 per 1,000 units above your tier. Budget above the tier you think you need.
Can you export code from Bubble?
No. There is no code export, so an app built on Bubble stays on Bubble. If portability matters to you, a code-first tool — Replit, v0, Lovable's GitHub sync, or kitty.build writing into your own repo — is the safer choice.
Is Bubble still worth it in the AI era?
For complex, logic-heavy applications, yes: no AI chat builder currently matches Bubble's data modelling and workflow depth, and the hiring market around it is real. For a straightforward product with a marketing site, AI builders are faster and cheaper.
Should I switch from Bubble to kitty.build?
Only if the gap you keep hitting is the one kitty.build closes. kitty.build is the only tool in this set that both refuses to build a bad idea and builds the good one. Nine boards research the live web, cite what they find and return a GO / PIVOT / NO-GO verdict for free; if the verdict is GO, the same product ships the site on your domain, writes the code into your GitHub repo and runs daily cycles where a task only counts as done with evidence attached. The trade is that it is a subscription and it is opinionated. If you want a single document, or you want to art-direct every pixel yourself, something else on this list fits you better. Where Bubble still wins: For a complex, logic-heavy application that has to work for years and might one day be handed to a contractor, Bubble is the safer platform. It has a decade of production use, a deep plugin ecosystem and a real hiring market. kitty.build's generated sites and repo commits are not a substitute for a mature visual app platform, and pretending otherwise would be dishonest. The first kitty.build verdict is free with no card, so you can find out without cancelling anything.
