RUAL is a platform where you build web applications from blueprints: visual flows of connected blocks that run on a cluster. Pages, APIs, storage and scheduled work are all built on the same canvas, without writing backend code.

Do I need to write code to build an application in RUAL?

No. Pages, API endpoints, storage queries and background jobs are built by connecting blocks on a blueprint canvas. Pages are templates rendered on the server, and you can add your own scripts when you want custom front-end behaviour, but that is optional.

Where do I start with RUAL?

Start with the Quickstart, which takes about 15 minutes and ends with a live Hello World page and a working JSON API endpoint. After that, the First CRUD App tutorial covers creating, listing, updating, deleting and searching documents.

2,000+ blocks 52 REST APIs 44 integrations

Build websites, APIs and automations in blueprints

RUAL is a visual platform: you connect blocks on a canvas, and it runs as your backend and your website. This is everything you need to know to build on it.

Web Pages New Build websites and webshops in a blueprint: pages rendered on the server from templates, with SEO built in, and actions that update only what changed. 15 pages Cluster and API Everything around the cluster itself: getting an account, managing who may do what, and exposing your own REST endpoints. 8 pages Blueprints The visual programming model: how flows execute, how storage works, and the patterns that keep large blueprints readable. 22 pages Blueprint Language Blueprint Language is the text form of a RUAL blueprint: edit it by hand, with an AI agent or in the Studio code view, and stage the change on the canvas. 5 pages Integrations Connect RUAL to the services you already use: payments, mail, messaging, AI, cloud storage, shipping, accounting and single sign-on. 45 pages Studio The cluster management interface: signing in, the canvas context menu, and how to replace the login and system pages that ship by default. 4 pages Tutorials End-to-end builds. Each tutorial starts from an empty blueprint and ends with something running: APIs, logins, dashboards, email, uploads and AI. 12 pages Home Automation Run the building the node sits in: Zigbee, Thread/Matter, Z-Wave, Hue and Daikin devices in one vocabulary, automated by blueprints with no vendor cloud. 8 pages Examples Reference applications. Each one shows the document design first, then the flows that read and write it: a blog, a shop, bookings, stock and tasks. 6 pages Reference Lookup material. Short pages you come back to rather than read once: blocks, API endpoints, system settings, component props, error codes and more. 6 pages Architecture Decisions you make once per project, and the reasoning behind them: which approach fits, versions and upgrades, Core Nano versus a cluster, and scaling. 4 pages Troubleshooting When something does not do what you expect, start here: common issues and their fixes, and how to debug a blueprint with the console and simulation. 2 pages

In three steps

From an empty canvas to a live page

Everything in RUAL is a blueprint: a canvas of blocks, connected into flows.

1
Place the blocks
A web_page with a URL and a web_render with your template. An API or a scheduled job starts the same way.
2
Connect your data
Read from a storage, call an outside service and wire the values into the blocks that need them.
3
Activate it
Activating makes the blueprint live on your cluster, with nothing to build and nothing to deploy by hand.
