The Tarantula cloud

Seven building blocks. One tiny cloud.

Seven pieces cover deployment, data, login, knowledge, company tools, background code, and operational agents. They ship together.

$ npx tarantula deployOne app · one deploy · one permission model

Build

Your coding agent writes one ordinary app.

Deploy

Tarantula creates everything it declares.

Invite

Send one private URL to a person or team.

Keep going

Jobs and agents continue after the tab closes.

The building blocks

Friendly on the surface. Literal in code.

Fun names make the system easier to remember. The TypeScript primitives stay unsurprising for coding agents.

Ship / Deploy & share

Launchpad

Deploy web apps and APIs in one command. Previews, private URLs, custom domains, TLS, logs, and rollbacks are already handled.

web()

Remember / Managed database

Tables

A managed relational database with schemas, migrations, indexes, transactions, backups, and a simple typed API.

database()

Invite / Login, teams & permissions

Door

Sign-in, sessions, teams, invitations, roles, app identities, and row-level authorization built into every app.

auth()

Know / Files & company knowledge

Library

Keep files, policies, notes, and generated artifacts in one permission-aware library that apps and agents can search and use.

storage()

Connect / Company tools & app-to-app access

Switchboard

Connect SaaS tools, internal APIs, and other Tarantula apps once, then grant narrow capabilities without exposing permanent credentials.

connection()

React / Functions, jobs & webhooks

Spark

TypeScript functions for APIs, webhooks, queues, cron jobs, and background work—deployed beside the app that uses them.

worker()

Operate / Operational agents

Loop

Durable runs, model access, browser and code tools, checkpoints, retries, approvals, and complete traces in one runtime.

agent()

One app contract

The pieces know about each other.

Door permissions apply to Tables and Library. Switchboard tools are available to Spark and Loop. Launchpad deploys the complete app—not seven separate projects.

Read the developer model

tarantula.ts

export default defineApp({
  web: web("./app"),
  database: database({ accounts }),
  auth: auth({ audience: "team" }),
  storage: storage({ knowledge: true }),
  connections: [slack, hubspot],
  agents: [renewalReview]
});

That is the whole cloud.

Start small

Pick one useful app. The cloud is already there.
