Free · no signup · no credit card

Free Postgres for your prototype

You need a database right now, not in 10 minutes after signing up for something. Run402 gives you a real Postgres database — with REST API, auth, storage, and hosting — for free on testnet. Build a working prototype and demo it before spending anything.

Three steps to a live app

Get free testnet USDC

Call POST /faucet/v1 — you get a wallet with 1.00 USDC on Base Sepolia. No human signup, credit card, or dashboard setup.

Provision a database

Follow the complete CLI tutorial, then run run402 up --name my-app -y. A fresh Cloud profile uses the free testnet prototype path. Inspect the result and verification before reporting the app ready.

Build and deploy

Create tables, set up auth, add data via REST API, and deploy a frontend to *.run402.com ($0.05 testnet). Hand your human a live URL.

From zero to running database

# Prepare run402.json and every referenced file from docs.run402.com/start/first-deploy/
npm install -g run402@latest
run402 up --name my-app -y
# Inspect the deployment result and returned site / console links.
run402 up verify

What you get for free

Every prototype database comes with the full stack. No add-ons, no upgrade walls.

Why not just sign up for something else?

No signup means no waiting

No account creation, no email verification, no project wizard. The CLI creates the database as part of your application workflow. Your agent can do this autonomously.

No credit card means no risk

Testnet USDC is free. Build as many prototypes as you want. When ready for production, two paths: fund the wallet with real USDC on Base and your agent pays autonomously, or buy Run402 credits via Stripe with a credit card.

Everything in one place

Other services give you a database but you still need to find hosting, auth, storage, and an API layer. Run402 includes all of it. Two API calls = full webapp with a live URL.

Prototypes are ephemeral by design

Prototype databases never expire and are never deleted for non-payment: one testnet payment, once. No forgotten billing, because there is none.

When you're ready for production

Two upgrade paths. Same API, same keys, no migration.
