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.

One Config. Full Application.

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

YAML 
name: company-crm
version: 1.0.0

tables:
  - name: contacts
    fields:
      - name: full-name
        type: single-line-text
        required: true
      - name: email
        type: email
        required: true
      - name: company
        type: single-line-text
      - name: stage
        type: single-select
        options: ['Lead', 'Qualified', 'Customer']
      - name: deal-value
        type: currency
        currencyCode: USD
      - name: notes
        type: long-text
      - name: owner
        type: user

auth:
  strategies:
    - type: emailAndPassword

theme:
  colors:
    primary: "#3b82f6"

pages:
  - name: home
    path: /
    meta: { title: Company CRM }
    sections:
      - type: heading
        content: Welcome to your CRM

Start from any format:

Terminal 
sovrium start app.yaml            # YAML (recommended)
sovrium start app.json            # JSON
bun run app.ts                    # TypeScript with full type safety
