Build complete apps with a single config file

Open-source. Self-hosted. Configuration-driven.

Define your tables, auth, pages, and theme in one file. Sovrium turns it into a full-stack application you own and control.

One Config. Full Application.

Sovrium turns a simple configuration file into a complete business application — authentication, database, API, pages, and admin panel included.

// app.ts — Type-safe, with IDE completion import { start } from 'sovrium' await start({ name: 'Company CRM', tables: [{ name: 'contacts', fields: [ { name: 'name', type: 'single-line-text' }, { name: 'email', type: 'email', required: true }, { name: 'status', type: 'single-select', options: ['Lead', 'Customer'] }, ]}], pages: [{ path: '/', name: 'Dashboard' }], auth: { strategies: ['email-password'] }, })

Also works with YAML and JSON configs:

sovrium start app.yaml # or app.json bun run app.ts # TypeScript with type safety

How It Works

1

Configure

Define your app schema in TypeScript, YAML, or JSON.

2

Deploy

Run on your server, your cloud, your laptop.

3

Own

Full source code access, full data control.

4

Evolve

Add features by updating your config. No migration pain.

Companies worried about vendor lock-in

The Hidden Costs of SaaS Dependency

❌
Vendor Lock-in — Your data, workflows, and team habits are trapped in someone else’s platform.
❌
Per-Seat Pricing — Costs scale with headcount, not value. Growing your team means growing your SaaS bill.
❌
Feature Bloat — You pay for thousands of features you never use, while the ones you need are behind enterprise paywalls.

Why Not Just Use SaaS?
