Lovable vs v0, and which one to build your app with

Pick Lovable if you want the app, its database and sign-in all run by Lovable, with no hosting or database account of your own to set up. One credit balance covers the whole workspace, however many people are in it.

Pick v0 if you want the app in your own Vercel account and its data at a provider you pick. Adding one of v0’s database integrations provisions a new account on that service, such as Neon or Supabase, which you manage through the Vercel Marketplace. v0 also suits you if you want Design Mode’s visual editing or already run your infrastructure on Vercel. Its plans price each person separately, and you pay for it on top of whatever your Vercel hosting already costs.

Either way, what your visitors ask once the app is live lands with you, and that’s the part Deacon takes on.

Whichever builder you pick, your users’ questions come to you once the app is live. On Lovable, a support chatbot you build runs through its AI connector and, once the 4-credit monthly AI grant is gone, spends the same credits as your next feature. On v0, you’d prompt one into your Next.js app, paying per token for every change, and look after it from then on. Deacon is the support chat you add rather than build. It replies to your visitors in seconds from your own docs, at any hour and in the language they write in. If your docs don’t cover a question, it says it doesn’t know instead of guessing and offers a box for the visitor’s email. When they leave an address or ask for a person, you get an email about three minutes later unless someone on your team is already in the dashboard, and what you type back in Deacon’s dashboard shows up in their chat, which stays open for your reply for three days.

Its replies come out of Deacon’s own plan, so a busy week of questions never touches your Lovable balance or your v0 credits. Seats come with the plan too, which counts on v0, where every teammate is billed. A question Deacon couldn’t answer waits for you with an Answer this button, and whatever you write there becomes something it answers from, so it needs you less over time.

Deacon also gives you a list of what to build next. Every conversation is kept, and you can search them by what the visitor asked. Topics group similar questions, count the people asking, and mark a topic as a bug report, a feature ask or a how-to when one kind of question leads it, which makes a good brief for your next Lovable or v0 prompt. The same script counts your visitors and where they came from, along with your goals, funnels and the JavaScript errors people hit, with an all-time range that goes back further than Lovable’s 90 days. On a v0 app, that’s traffic numbers without setting anything up in Vercel.

Adding Deacon is one script tag. Install gives you a prompt for Lovable’s chat and another for v0’s, and each also passes Deacon who’s logged in, if your app has logins. On Lovable, paste it into the project chat, and Deacon and Lovable walks you through it. On v0, the tag goes in your app’s root layout, where v0 puts it from its own prompt, and Deacon and v0 shows exactly where.
