“Build an app just by chatting.” All four AI app builders make that promise. Their pricing models, code ownership and security records are where they really differ.
Evidence review of official pricing and documentation, the US vulnerability database, security research and company disclosures, checked 14 Oct 2026. Hyptor Lab’s same-spec build test is scheduled. No affiliate links. How we test
The short answer
They all build apps from prompts, but none has independent proof it builds better ones. The biggest risk isn’t the builder — it’s shipping its output without a security review: Lovable and Base44 have both had serious, documented security issues.
Most generous free usage: Bolt (1M tokens/month) · Cheapest paid entry: Base44 Starter, $16/mo billed annually · Developers: v0 (Next.js, deploys to Vercel) · Confidence: Medium on prices and security record; no neutral quality benchmark exists.
What they claim vs what the evidence shows
| Their claim | Verdict | What the evidence shows |
|---|---|---|
| Build apps “with no technical knowledge needed” (Lovable) [1]; “No code” (Base44) [4] | Holds, with caveats | You can generate an app without code — but security research found that without technical review, generated apps can expose data (see below) [18][19][28]. |
| “Production-ready starting points” (Bolt templates) [2]; “ready to ship on day one” (Base44) [4] | Overstated | A scan of 5,600+ apps from AI builders found more than 2,000 vulnerabilities and 400+ exposed secrets [28]. “Ready to ship” still needs a security check. |
| Lovable: GitHub repos “private by default, on every plan” [6] | Holds, with caveats | Lovable says private projects were never affected, but admits that from Feb–Apr 2026 chats and code of public projects could be read by any user with the link [20]. |
Why this matters
Founders and non-coders are putting real customer data into apps they didn’t write and can’t easily inspect. Credit-based pricing also makes the true cost hard to predict: complex changes burn more credits than simple ones.
How we built this verdict
We read each builder’s pricing page and documentation [1–17], the National Vulnerability Database [18], the researchers’ and vendors’ own disclosures [19–23], and reputable press for company facts [24][26][27]. Comparison posts from affiliates or competitors were excluded. Lovable’s homepage blocked automated access, so its prices come from its docs.
Four different ways to charge you
| Builder | Free | Cheapest paid | How usage is counted | Code ownership |
|---|---|---|---|---|
| Lovable | 5 credits/day (up to 30/month) | Pro $25/mo, 100 credits | Per message, scaled by task complexity | Two-way GitHub sync; code downloadable |
| Bolt | 1M tokens/month (300K/day) | Pro $25/mo, from 10M tokens; unused roll over | Tokens — bigger projects use more per message | ZIP export; GitHub |
| v0 | 7 messages/day; $5 one-time credit | Plus $30/user/mo with $30 credits | Dollar credits drawn down per token | GitHub sync (incl. Free) |
| Base44 | 25 message credits/month | Starter $16/mo billed annually | Message + integration credits | GitHub sync on Builder plan+ |
In practice: Bolt’s token model and Lovable’s complexity-based credits both mean big projects cost more per change. Try your real project on the free tier before committing.
Lovable’s security record
Finding: CVE-2025-48757 (rated 9.3, critical) describes missing database access rules that let “remote unauthenticated attackers … read or write to arbitrary database tables of generated sites”; Lovable disputes it, saying customers are responsible for protecting their data [18]. The researcher found 170 of 1,645 apps he scanned exposed [19]. Separately, Lovable admitted that public projects’ chats and code were readable by other users from 3 Feb to 20 Apr 2026, fixed it “within two hours” of acting, and said its initial response “missed the mark” [20][21].
In practice: if you build on Lovable, check your database access rules yourself and keep sensitive projects private.
Base44’s security record
Finding: in July 2025, Wiz found that attackers could register on private Base44 apps using only a non-secret app ID; it was “fixed in less than 24 hours”, and Wix said there was “no evidence of exploitation in the wild” [22]. Imperva had earlier reported several flaws, including stored XSS; the vendor fixed them, though the first redirect fix was incomplete [23].
The surprise: no news isn’t proof of safety
We found no platform vulnerabilities reported for Bolt or v0. That’s good — but it’s an absence of evidence, not proof of security. Bolt even documents a scanner that flags missing database access rules [16], an acknowledgement that the risk applies to everyone building this way.
Where each one genuinely shines
Lovable: built-in backend (Lovable Cloud) plus Supabase integration and two-way GitHub sync [6][15]. Bolt: the most generous free token allowance and rollover on paid plans [7]. v0: standard Next.js/shadcn code and one-click Vercel deploys — easiest for developers to take over [3][11]. Base44: cheapest paid entry and a fully managed backend, now owned by Wix (bought for $80M in 2025) [13][17][24].
Which builder should you use?
Non-coder testing an idea: start on Bolt’s or Lovable’s free tier. Developer who wants clean, portable code: v0. Lowest monthly cost: Base44 Starter (annual). Anything with real user data: whichever you pick, get a security review before launch. If you can code, compare with AI coding assistants.
Questions people ask
Is Lovable better than Bolt?
No neutral benchmark compares them. Bolt offers more free usage [7]; Lovable has a built-in backend [15] but a heavier security record [18][20]. Test both on your project.
Can you build a real app without coding?
You can build a working app, yes. Making it safe for real users still needs technical checks — especially database access rules [18][28].
How much do AI app builders really cost?
Entry plans run $16–30 a month (see the table), but usage-based credits mean larger projects cost more per change.
The verdict
Prompt-to-app builders are genuinely useful for prototypes, but “production-ready” claims outrun the evidence — and the security record shows why. The decision: prototype freely; before real users or data, get the code reviewed.
