AI-powered coding (AI coding agent / build apps by chatting): I typed "hello test app" into the homepage prompt box and clicked "Build it". It sent me to a sign-up page (/auth?mode=signup&next=/onboarding), so I couldn't see the AI agent respond without an account. The docs site does have an Agent Guide and a Prompting Guide.E158E159E160
Growth analytics dashboard: The analytics dashboard is only described on the homepage. The app is behind sign-up, so I couldn't open or check any analytics view.E157E159
All-in-one working platform (one-click publishing, integrated payments): The builder, publishing and payments all sit behind sign-up, so I couldn't try them. The docs describe publishing, monetization and over-the-air updates. The public Showcase page did load a list of community apps from a0.dev/api/showcase and a Supabase projects endpoint.E159E160E162
Tech check: the site claims ai / agents, live data / analytics and a working app / platform, and its public page shows matching evidence.E153E154E59E83E49
Before you click anything, the page loads analytics or ad services: Google Analytics / Tag Manager, Meta Pixel, Google Ads / DoubleClick and Meta / Facebook.E4E8E14E11E15

What the AI agent tried
An AI agent (claude-opus-5-5) used the site in our sandbox for 6 steps and saw 0 of 3 claimed features working. It can't connect a wallet, pay, sign or log in, so those features count as "couldn't test". What it reports is what it observed, not a verdict.
Couldn't test

Also noticed
Things the agent saw along the way that aren't among the site's claims. Not counted above.
Noticed
public Showcase page
/showcase loaded about 30 user apps, each with a creator name and two counts, using data fetched from a0.dev/api/showcase and a Supabase projects endpoint.E162
What it is
The Internet Archive first saved this site on 2024-11-14 (720 days ago).E156
The site describes itself as: “World's fastest iOS & Android app builder. Production-ready mobile apps that deploy directly to App Store & Google Play in minutes.”E2
It's built with React and Next.js (common tools for building web apps).E36E37
Notable building blocks in its code: Socket.IO (live connection) and Supabase client.E38E39
In your browser it can ask to use your camera or microphone, can copy text to your clipboard, saves small bits of data in your browser, keeps a live two-way connection open to a server and 2 more.E46E47E48E49E50E51
It has sections such as /showcase, /pricing, /blog, /docs, /contact and /privacy.E147E148
While loading, it called 4 endpoints on its own servers, such as /ingest/flags/, /rive/build.riv, /g/collect and 1 more.E54E55E56E57
Where your data goes
Analytics & trackingCount visits and record what you do on the page.2
www.googletagmanager.com
Google Analytics / Tag Manager: Google's visitor analytics and tag loader
personal_sign: asks you to sign a text message (often to log in; moves no funds by itself).E152
eth_requestAccounts: asks to connect your wallet, which shows the site your address.E151
How key features work
Connecting your wallet
It connects to crypto wallets using personal_sign and eth_requestAccounts. Connecting shows the site your wallet address; it doesn't move funds by itself.E151
personal_signeth_requestAccounts
AI features
Parts of the site talk to AI services or AI endpoints (/ai/transfer-session and /ai/message-limits). Text you type there may be sent to them.E59E83
/ai/transfer-session/ai/message-limits
Payments
Payments are handled by Stripe and Stripe.js, so card or payment details go to them, not only to this site.E7E17E18E45
StripeStripe.js
Sign-in and accounts
Sign-in and account features show up in its code or traffic (/ai/transfer-session, /payments/create-onboarding-checkout-session, /api/google-play/oauth/initiate, /api/google-play/oauth/grant-access and 1 more).E59E65E77E5
Every sentence above points to one of these. Code references show the file, line:column and the short identifier that matched, never the site's code itself.

We only see what your browser sees: code and requests on a first visit, without logging in or accepting cookie banners. What the servers do with data is invisible from outside.
Site code is usually minified (compressed), so names are partly lost and some code may be only partly analysed.
Some trackers only load after you accept cookies or log in, so the real list can be longer.
We visited from a server in the United States. Sites load different trackers and cookie banners in different countries (visitors in the EU usually get a consent banner first).
The tech check compares the site's own words with what its public page loads. Work done on servers, in private code or in separate apps isn't visible here, so 'nothing found' means not visible on the public page, not that it doesn't exist.
This text was written from fixed templates because no AI writer was available. It uses exactly the same evidence.
The code reader hit its size budget on parts of 125 large bundle file(s); those parts weren't fully analysed.
Facts, not judgements: this page describes what the code and traffic show, not anyone's intent. Not financial advice. Case id XoWaH8AF.

1 of 3 · What it does
Know the coin before you buy it
Paste any coin address, wallet or X post. We scan it in seconds, free, no sign-up.
Every coin gets a green, yellow or red light and a score out of 100, and every point links to its source.
2 of 3 · How to read a check
Three questions, then the money
Is the tech real? Is the dev legit? Fair launch? Each has its own score and its top reasons.
Who's behind it: the dev's linked wallets, crews that buy launches together, and the launch block by who paid for it.
Money taken out: what the dev and launch-block wallets sold or pulled in the first 24 hours.
3 of 3 · Stay on it
Track coins and wallets
Press Track on any coin or wallet. You'll get a browser notification when the dev sells, liquidity is pulled, the price moves hard, or a tracked wallet trades.
No account: it's tied to this browser. See everything you track under Tracking.
