# Arc Studio

Snapshot 2026-11-02 · 33 apps on GitHub · [JSON](https://builder.registrai.cc/arc/studio/data.json)

Apps built with [Arc Studio](https://studio.arc.io), Circle's AI coding agent for Arc, that are public on GitHub: their sites, contracts on Arc and USDC paid through them; the Studio CLI and what changed. (i: Arc Studio builds an app from a prompt and deploys its contracts to Arc testnet only, so a contract on mainnet was deployed outside it. Updated weekly.)

## In numbers

| Apps built with Arc Studio on GitHub | 33 |
| --- | --- |
| With a site | 19 |
| On their own domain | 3 |
| With contracts on Arc testnet | 20 |
| With a testnet contract deployed through Circle's contract deployer | 18 |
| With contracts on Arc mainnet | 8 |
| With USDC paid through their mainnet contracts, last 30 days | 3 |
| In the Arc ecosystem directory | 6 |
| Other repos that use or mention Arc Studio | 27 |

## Arc Studio CLI

[@circle-fin/arc-studio-cli](https://www.npmjs.com/package/@circle-fin/arc-studio-cli) on npm: 56 downloads on the last day, 668 in the last week, 1,238 in the last month. 10 releases since 2026-08-29; latest 1.2.2 on 2026-10-23.

## Apps built with Arc Studio

Sorted by repo name. Mainnet payments: USDC paid through the app's mainnet contracts in the last 30 days. (i: A payment is a transaction through one of the app's mainnet contracts in which the sender moved USDC, native or ERC-20, counted once from Arc's USDC system events; the app's own payouts and transfers to oneself are not payments. USDC an app moves through shared contracts (for example Arc's Multicall3From) cannot be told apart from anyone else's and is not counted.)

## Method

Public GitHub repos with Arc Studio's fingerprint, the contracts their files name, and USDC paid through those contracts on mainnet. (i: Public GitHub repositories whose code contains "preview.studio.arc.io" (Arc Studio writes it into the apps it exports) or "@circle-fin/arc-studio-cli". Contracts are addresses written in each repo's config and deployment files, checked for code on Arc testnet and mainnet. Mainnet payments: USDC the sender moved in transactions through the app's mainnet contracts, last 30 days. Arc Studio writes `preview.studio.arc.io` into the Vite config and session log of every app it exports; a repo is counted as an app built with Arc Studio when the match is in one of those files, and as a repo that mentions Studio otherwise. Forks are left out. Addresses shared by many apps (USDC, EURC, Permit2, Multicall3, EntryPoints, contracts of other projects in the directory, and any address found in three or more of these repos) are not counted as an app's own. Contracts created by factories that put the same contract on every chain (Safe, CREATE2, CreateX, EntryPoint) are left out, and so is a mainnet address that GitHub code search also finds in another owner's repo (a token or protocol the app uses; Registrai's own repos do not count). An app is linked to a directory entry only when that entry names the app's repo or its GitHub owner. Arc Studio deploys through Circle's ContractBytecodeDeployer (`0xa3039A54856ed74B5AEc999EeF3fc954Ab010Cf6` on testnet); other Circle tools use it too. A contract at an address from the repo is a strong sign, not proof, that the app deployed it.)

Not covered: private repos, apps never pushed to GitHub, preview links (they share one wildcard certificate, so they cannot be listed), and Studio's sign-ups and sessions, which only Circle has. Registrai is not run or reviewed by Circle or Arc. Data CC BY 4.0.
