One Config. Complete App. Full Control.
Build the tools your team needs, own your data, and never get locked into a vendor again.
Describe your app once — tables, auth, pages, and automations — then run it on infrastructure you own. No per-seat pricing, no vendor lock-in.
Install in one line:
curl -fsSL https://sovrium.com/install | shSource-available · BSL 1.1 · Built with Bun, Effect.ts, Hono & React 19
From nothing to a running app in three steps.
Sovrium is AI-native by design: the config reads like plain instructions, so an AI agent can write it for you. It came before AI, and it runs perfectly without it.
Install Sovrium.
One command on your own machine or server. No account, no cloud.
Ask an AI agent to write the config.
Describe what you need to Claude Code, or any AI agent, and it writes the configuration for you.
Run it.
Point Sovrium at the config and your app is live — tables, auth, pages, and a typed API included.
See what a single config can become.
Every one of these is one Sovrium configuration — from a one-page starter to a full client portal. Read the configs, run them, make them yours.

The SaaS Trap
106 SaaS apps. $21M wasted.
The average organization uses 106 SaaS apps and wastes $21M annually on unused licenses.
Productiv, Zylo 2025
Lock-in
Your data lives in silos you don’t control. Proprietary formats, closed APIs, and zero portability mean your business runs on someone else’s terms.
Cost Spiral
Per-seat pricing compounds against you. What starts at $10/user quietly becomes $50, then $100, and you’re too locked in to leave.
Platform Decay
Free tiers shrink, paywalls expand, switching costs grow. Airtable cut free API calls from unlimited to 1,000. Notion eliminated its AI add-on. This pattern is structural, not accidental.
There’s a better way.
Write one file. Run a complete app.
Write one config file and get the whole app — authentication, database, API, pages, and an admin space. Nothing to wire together.

What is Sovrium?
Sovrium is a self-hosted, configuration-driven platform. You define your tables, authentication, pages, and theme in one config file and deploy a complete application on your own infrastructure.
Is Sovrium free?
Yes. Self-hosting is free under the BSL 1.1 license — every feature, no license key, no per-seat fees. Managed hosting (Sovrium Cloud) and Partner plans are optional paid services.
How is it different from Airtable, Retool, or Notion?
Your data and source live on your own infrastructure, not a vendor cloud. No lock-in, no per-seat pricing, and you can edit the config with any editor or AI agent.
Do I need to be a developer?
Sovrium targets technical teams, but its config is human-readable (YAML, JSON, or TypeScript) and AI-assistant-friendly, so the whole team can contribute.
