Shipcheck

Pre-launch review gates non-technical builders run on their own vibe-coded apps

A self-serve gate a Lovable or Bloom builder runs before shipping: it scans the generated app for exposed keys, open database rules, missing auth on routes and broken payment flows, explains each finding in plain language, and blocks the builder's own publish step until they accept or fix each one.

Test it before you build it

$500 · 3 weeks · 30 prospects

For $500 and 3 weeks, prove that 8 of 30 non-technical Lovable builders charging real customers will prepay $75 for a pre-publish security gate before any incident forces them to.

Riskiest assumption · A non-technical builder charging customers through a Lovable app will pay for a security gate before anything has gone wrong, rather than trusting Lovable to handle it - if only breached builders pay, the market is too small and the platform owns the fix

1Focus group: who and where

A solo builder with no coding background who shipped an app on Lovable, wired up Supabase and Stripe, is charging real customers, and has seen at least one post about leaked API keys - so the worry is live this month but nothing has broken yet

where to find 30 · Product Hunt launches whose maker comments credit Lovable (a browsable list of shipped, paying apps), the r/lovable subreddit and Lovable's official Discord (the community where these builders ask for help), and X posts under #buildinpublic that show a Lovable app with a pricing page (the channel where they announce charging customers)

2Sell first, build later

Founding gate: a full outside-in review of one deployed app - exposed keys, open database rules, missing auth on routes, broken payment flows - as a plain-language report within 72 hours, then a re-check on every publish for 3 months, starting the day payment lands

the ask · $75 prepaid for 3 months, price locked at $25 per month afterward for the first year

a real yes · A real yes is $75 charged to a card; upvotes on the write-up, 'this is so needed' comments and free-scan requests without payment do not count

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

  1. 1. Free finding, paid gate pre-sale

    $100 · 10 days

    Find 30 shipped Lovable apps with pricing pages via Product Hunt and #buildinpublic. DM each builder asking permission to check their app from the outside only - client-side bundle for exposed keys, unauthenticated API routes, open database rules - then send the single worst finding free, in plain language, within 72 hours. Close each delivery with the founding offer: full report plus a re-check on every publish, $75 prepaid for 3 months.

    keep going if · 6 of 30 builders pay the $75 after seeing their free finding

  2. 2. Priced landing from audit write-up

    $150 · 7 days

    Publish a write-up of the anonymized results ('I reviewed 20 live vibe-coded apps with permission; here is what leaked') in r/lovable and on X, linking to a one-page site with the $75 founding offer and a card checkout. One founder writes it, same week as experiment 1.

    keep going if · At least 300 visitors, 3% start checkout, 5 complete payment

  3. 3. Fear or indifference calls

    $250 · 7 days

    Book 10 20-minute calls with builders who saw their finding but did not pay, offering a $25 gift card each. Ask what they would do if their user table leaked tomorrow and who they believe is responsible for preventing it - them or Lovable.

    keep going if · 7 of 10 name a concrete security fear unprompted; fewer than 5 saying 'Lovable handles that' keeps the thesis alive

4Collect a deposit up front

Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.

$75

per prospect, refundable

how · Prepaid first quarter through a hosted card checkout on the landing page - this buyer already pays Lovable $25 a month by card, so a card checkout is the native rail and anything heavier (invoices, contracts) would be slower than the buyer expects set up: Stripe Invoicing ↗

what it reserves · One of 20 founding slots, the first report within 72 hours, and the $25 per month price locked for a year

refund · Full refund any time in the first 30 days, one email, no questions

target · 8 payments of $75 from 30 pitched builders within 21 days

Go: build it if

8 or more of 30 pitched builders pay $75, and at least 5 of the first 10 reports lead to the builder fixing a finding within a week

Kill: stop if

Fewer than 3 of 30 pay after seeing a real finding in their own app, and landing checkout starts stay under 1% - the fear is not worth $25 a month before an incident

The concept in full

What
A self-serve gate a Lovable or Bloom builder runs before shipping: it scans the generated app for exposed keys, open database rules, missing auth on routes and broken payment flows, explains each finding in plain language, and blocks the builder's own publish step until they accept or fix each one. In the first hour a user connects a project, runs the first scan, and fixes the two findings that would have leaked their user table.
Grounded in (2025-2026 signals)
'On November 6, 2025 Collins Dictionary named vibe coding... its Word of the Year'. 'Lovable reached $200 million ARR in November 2025 and about $500 million by June 2026... 80% of the people building on it are not developers', plus Lovable's $400 million raise on 2026-08-12. YC's Fall 2026 RFS includes A Cloud for Small Software.
What it rides
'Vibe coding' is Collins' Word of the Year 2025. Millions of non-developers now publish software with no review step of any kind; the missing piece is a gate the builder controls, not a security product aimed at engineers.
Why now
Lovable went from $200 million ARR in November 2025 to about $500 million by June 2026 with 80% non-technical builders, so the population shipping unreviewed production software roughly doubled in seven months; YC's Fall 2026 A Cloud for Small Software RFS points at exactly this tail of small shipped apps needing grown-up operations.
Wedge: first customer and entry point
Non-technical builders charging real customers through their vibe-coded apps; entry point is a free scan of one deployed app with plain-language findings, converting to $25 a month for every-publish gating on up to five apps.
Closest real companies, as the generator saw them
StarSling (yc X25) builds self-driving CI for GitHub Actions and speaks to developers; Shipcheck speaks to the 80% who have never seen CI. bitrig (yc S25) bundles testing into its own Swift platform; Shipcheck gates apps built anywhere.
Main risk
Lovable builds an equivalent pre-publish check into its own deploy flow and the platforms own the moment of shipping.
