Nock
Open workspace
Browser-native Robinhood workspace

From idea to a liveRobinhood app.In one tab.

Pick a verified crypto template. Nock opens the files, runs the tests, catches the first ship error and gives you the TypeScript zip without local setup.

Everything a Robinhood app needs, already running.

Watch Nock resolve a runtime, install the dependencies, issue a sandbox key, hit a real revert from an amount in the wrong decimals, and patch itself — without you installing anything.

02Evidence loop

The agent stops on evidence, not on a claim.

Nothing is reported as done that a command did not report first. A failing suite sends the agent back to the file it just edited, and the loop does not move on until the test is green.

Evidence loop · auto run

  1. Writenock editqueued

    Reads the project first, then edits only the files the change actually touches.

  2. Testnpx vitest runqueued

    The suite runs on every change. A red test sends the agent back to the file it just edited, it does not get explained away.

  3. Typechecknpx tsc --noEmitqueued

    The type checker runs for real. Its output is the evidence, not a summary of it.

  4. Shipnock ship --sandboxqueued

    Ships against your sandbox key, then to a shareable URL. A funded account is never wired at all.

Latest evidence

every claim is held until a command reports it.

03Starting points

Every template starts already building.

Six apps you would actually ship — a mint, a tokenized asset, an escrow, a gate, an order desk, an on-ramp. 70 tests across the set, each one installed, type-checked and running before it reaches you.

NFT mint

A phased mint with an allowlist, a per-wallet cap and a supply cap, sponsored so the minter pays no gas.

04Nock Labs

Nock is a product workspace for crypto builders.

It turns a Robinhood crypto idea into a working TypeScript project: files, tests, preview, terminal output and a download you can keep. The demo is sandbox-only by design, so the product can be fast without pretending real money is one click away.

No local toolchain to install.
Templates ship with source, tests and a sandbox key.
Robinhood surfaces stay clearly separated from real-money accounts.
