From nothing to a running app in three steps.

Three commands and the application is serving. Each step shows the command and what it actually prints.

>_ terminal
curl -fsSL https://sovrium.com/install | sh
sovrium 0.20.0 installed to /usr/local/bin/sovrium
>_ terminal
sovrium init hello-world --template hello-world
Created hello-world/app.yaml from the hello-world template

1

Install Sovrium.

One command, on your machine or your server. No account, no cloud. Then scaffold a project from a template. Hello World is the smallest one that still runs.

Browse the templates
hello-world/app.yaml
name: hello-world

pages:
  - path: /
    components:
      - type: text
        element: h1
        content: Hello, world

2

Edit the configuration with an AI.

The config reads like plain instructions, so an AI agent can edit it for you. Give your agent the reference below and describe what you need. Sovrium came before AI, and it runs perfectly without it.

The reference to give your AI agent
>_ terminal
cd hello-world
sovrium start app.yaml
Sovrium listening on http://localhost:3000
The Hello World application running, served from its config file

Run it.

Point Sovrium at the config and the application is live: tables, auth, pages, a typed API, and an admin space to operate it.

Operate it from the admin space

Every feature is a few lines of configuration.

Tables, permissions, automations, forms, files, AI agents, theme. Pick one and read exactly what declaring it costs.

Tables and fieldsOver 40 field types, from plain text to currency, relations and formulas.Sorting, filters, searchTurn a table into a view your team can work in, without writing a query.Pages and componentsCompose a screen from blocks: headings, tables, forms, charts.Accounts and permissionsRoles down to the individual field, with unauthorized access answered as a 404.AutomationsReact to a record, a webhook or a schedule, and send the email yourself.Public formsCollect a submission from outside the app straight into a table.File storageAttach documents, with the size and type limits you declare.AI agentsGive an agent a role, the tables it may read, and the actions it may take.ThemeColours, fonts and radii as tokens. Every screen follows them.

tables:
  - name: contacts
