Short answer: Lovable is the better choice for founders who already know what to build and want the fastest, prettiest path to a working web app. Bolt.new is the better choice for prototypers who want to try five app ideas this week without paying, and who are comfortable steering an AI through the rough edges. On price, Lovable starts at $25/mo and Bolt.new at $25/mo. Full table, real strengths and real limitations below — and a third option at the end if neither is quite the shape you need.
| Area | Lovable | Bolt.new |
|---|---|---|
| What it is | An AI software engineer you chat with: describe a web app and it writes, previews and deploys it, with Supabase and GitHub wired in. | StackBlitz's in-browser AI app builder: prompt it and a full-stack app is written, run and deployed without leaving the tab. |
| Free tier | 5 build credits granted daily, capped at 30 per month, plus 20 monthly Cloud credits. | 1M tokens per month with a 300K daily limit — the most generous free allowance among the AI builders. |
| Entry price | $25/mo | $25/mo |
| Best for | Founders who already know what to build and want the fastest, prettiest path to a working web app. | Prototypers who want to try five app ideas this week without paying, and who are comfortable steering an AI through the rough edges. |
| Strongest at | The fastest path from a sentence to a working, good-looking web app in this whole set | The most generous free tier of any AI app builder here — 1M tokens/month without paying |
| Biggest limitation | Credits burn fastest when you are debugging, which is exactly when you can least afford it | Tokens are consumed by failed attempts, so error loops are expensive |
| The number worth knowing | Lovable's free tier grants 5 build credits a day capped at 30/month; Pro is $25/mo for 100 credits. | Bolt.new's free tier gives 1M tokens per month, and Pro at $25/mo starts at 10M tokens with unused tokens rolling over. |

Lovable is the best pure chat-to-app builder for founders, and if you have already validated your idea it is a better use of $25 than almost anything else. Its blind spot is structural rather than technical: it will build the wrong product as beautifully as the right one, because nothing in the product asks whether anyone wants it. kitty.build answers that question first — nine boards, live research, a cited verdict that is allowed to say no — and then builds and operates the survivor. If you are certain about the idea, use Lovable. If you are certain because you like the idea, validate it first.
Bolt.new is the best free way to find out whether an app idea is buildable, and the token rollover on Pro is the fairest metering in the builder category. What it does not do — like every builder here — is tell you whether the thing is worth building; it will happily burn 10M tokens on a product with no market. Use Bolt to answer "can this be built and how hard is it". Use kitty.build to answer "should it be", and then to keep the answer alive after launch with a site on your domain, code in your repo and daily operating cycles.
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.
If what you want is exactly what Lovable or Bolt.new is best at, buy theirs — we say so on every page. If the gap you keep hitting is that nothing checks whether the idea is worth building, that is the gap kitty.build was built for, and the first verdict costs nothing.
Nine boards research the live market, cite every claim and return GO / PIVOT / NO-GO — free, no card. Then pick your builder, or let Kitty ship it.
