What this means for you

Antimatter Compute only talked to its own servers while we watched.E1

  • Tech check: the site claims a working app / platform, and its public page shows matching evidence.E33E15E9E10
  • We saw no known analytics or advertising services load on the first visit.E1

Tech check

What the site says about itself, next to what its public page actually loads. Facts only, no verdict: you decide.

Evidence found

A working app / platform

“…rst answer in five lines. Antimatter speaks the OpenAI API, so the SDK you already use only needs a new base URL…”E33

Calls to its own backend: /api/meE15

Wallet code: WalletConnect / Reown, EIP-6963 wallet discoveryE9E10

What the AI agent tried

An AI agent (claude-opus-5-5) used the site in our sandbox for 0 steps. 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.

What it is

  • The Internet Archive first saved this site on 2026-10-01 (41 days ago).E34
  • The site describes itself as: “Every model is a planet. Antimatter is the drive. Browse every language model, talk to any of them, then build with one OpenAI compatible AP”E2
  • It's built with Next.js and React (common tools for building web apps).E7E8
  • In your browser it can copy text to your clipboard, installs a background script (offline use, push messages) and saves small bits of data in your browser.E11E12E13
  • It has sections such as /explore, /studio, /docs, /pricing, /atlas and /planet.E27E28
  • While loading, it called 1 endpoint on its own servers, such as /api/me.E15

Where your data goes

On a first visit the page only talked to its own servers (useantimatter.com).

Crypto and wallets

  • Wallet tools in the code: WalletConnect / Reown and EIP-6963 wallet discovery.E9E10
  • personal_sign: asks you to sign a text message (often to log in; moves no funds by itself).E31
  • eth_requestAccounts: asks to connect your wallet, which shows the site your address.E30
  • 1 contract or wallet addresses are written into the code.E32
1 addresses found in the code

Paste any of these into the box on the home page to get the contract's report.

How key features work

Connecting your wallet

It connects to crypto wallets using WalletConnect / Reown, EIP-6963 wallet discovery, personal_sign and eth_requestAccounts. Connecting shows the site your wallet address; it doesn't move funds by itself.E9E10E30

Sign-in and accounts

Sign-in and account features show up in its code or traffic (/api/auth/verify, /api/auth/logout, /api/auth/nonce and /api/auth/step-up/challenge).E20E22E24

Loading its content

Its content loads from its own API while you browse (/api/me).E15

/api/me

Drawing and editing in the browser

The page draws and edits graphics in your browser using the canvas.E14

Saving data on your device

It saves data in your browser (a service worker, localStorage and sessionStorage), so some things persist between visits.E12E13E6

Limits

  • 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 11 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 8SwWHUVJ.
