🔥 The Problem

Why We Built Zveltio

If you're a developer or run a software agency, you know the story:

📉

BaaS Platforms Have a Ceiling

They help you ship an MVP fast, but stop short of real business logic — CRM, automation, compliance, workflows.

💰

Enterprise Solutions Are Too Expensive

They're rigid, lock you into their ecosystem, and cost a fortune monthly.

♻️

Classic Frameworks

Force you to write the same "boilerplate" infinitely: CRUD, Auth, Permissions.

💻 How It Works

Think of It Like a PC

Zveltio is architected for absolute modularity

💾

Hard Disk

PostgreSQL: Robust, secure, relational data storage

⚙️

Operating System

Zveltio Engine: Single executable, ultra-fast (Bun + Hono)

🧩

Applications

Extensions: Install functionality, don't write from scratch

⚙️ The Foundation

Everything You Need, Right Out of the Box

📦

Single Binary

One executable. Bun + Hono. Runs on a €20 VPS with no cloud account required.

🔄

Zero-Downtime DDL

Ghost Tables: alter schema on 5M-row tables while users are active. No locks, no maintenance windows.

🌿

Environment Branching

Branch your entire schema like Git. One-click staging environments from production — diff, test, merge. The most complete schema branching built into a self-hosted Business OS.

🤖

AI Schema Generation

Describe your app in plain English. Zveltio generates collections, relations, permissions, and seed data automatically.

🔌

Bring Your Own Database

Connect an existing PostgreSQL database. Zveltio introspects the schema and generates admin UI, REST API, and permissions automatically.

🎯

Live TypeScript Types

Run zveltio generate-types once. Every .collection() call is fully typed — no manual interfaces, no codegen plugin.

👨‍💻 Built for developers

Simple API. Zero boilerplate.

REST, real-time, and TypeScript types — generated automatically from your schema.

REST API auto-generated from your collections
# List records with filters
GET /api/data/products?price[lt]=100&status=active

# Create a record
POST /api/data/orders
{"product_id": "...", "qty": 2}

# Real-time subscription
WS   /api/realtime/products
→ {event: "insert", record: {...}}
TypeScript SDK fully typed, no codegen plugin
// zveltio generate-types → fully typed
import { Zveltio } from '@zveltio/sdk'

const z = new Zveltio({ url: '...' })

// IDE autocomplete on every field
const orders = await z
  .collection('orders')
  .filter('status', 'pending')
  .find()

React, Vue, and vanilla JS SDKs included · Offline sync with CRDT conflict resolution · WebSocket real-time

🆚 A different category

Business OS, not BaaS

A BaaS gives you a database and an API. A Business OS runs your entire company — CRM, automation, compliance, documents, mail, POS, approvals, and more. Zveltio is the latter: one self-hosted binary that replaces a dozen SaaS subscriptions.

Typical BaaS / SaaS

(managed cloud, per-seat pricing)

Database + auto-generated API
Auth (email, OAuth)
File storage
Basic webhooks
CRM & deal pipeline
Automation flows with DLQ
Mail client (IMAP/SMTP)
Zero-downtime DDL (Ghost Tables)
Schema branching like Git
AI schema + query generation
Compliance (e-Factura, SAF-T)
Self-hosted, data never leaves you

Everything your company runs on SaaS — now self-hosted

One platform. Replace twelve subscriptions.

🤖

Native AI

Describe your app in plain language — AI generates the schema, migrates data, and answers SQL questions. Multi-provider: OpenAI, Anthropic, or self-hosted Ollama.

Automation Flows

Visual trigger/step flow builder with retry, dead-letter queue, and exponential backoff. Replace Zapier, n8n, or custom cron jobs.

👥

CRM

Contacts, organizations, deals pipeline, and activity tracking — all integrated with your collections. Replace HubSpot or Pipedrive at zero cost.

✉️

Mail & Communications

Full IMAP/SMTP client with AI-assisted compose, thread management, and encrypted credentials at rest. Your inbox, inside your platform.

📄

Content & Pages

Block-based CMS with drag-and-drop editor and headless API. Replace Contentful, Sanity, or Strapi — on your infrastructure.

Workflows & Approvals

Multi-step approval chains with SLA tracking, checklists, and immutable audit trail. Replace Monday, Jira, or bespoke approval flows.

🧾

POS & Invoicing

Point-of-sale, inventory, and procurement management. Integrated with e-Factura for automatic ANAF invoice submission.

🗺️

Geospatial

PostGIS field types: location, polygon, linestring. Proximity search, clustering, geofences. No separate geo data platform needed.

🔬

Edge Functions

TypeScript serverless functions in an isolated sandbox, deployed from your admin panel. Replace Cloudflare Workers or Lambda for server-side logic.

📋

Romanian Compliance

e-Factura UBL 2.1, SAF-T D.394, e-Transport, and procurement — all with ANAF submission. Built for Romanian institutions and SMEs.

🔒

Per-Field Encryption

Mark any field encrypted: true. AES-256-GCM transparent encrypt/decrypt — no application code changes required.

📜

Immutable Audit Trail

Every write logged with who, what, when, and from where. Filter by user, collection, or operation. One-click GDPR data export and right-to-erasure.

🎯 Built for teams that own their infrastructure

Stop paying per seat. Start owning the platform.

🖥️ Software agencies & consultancies

Stop rebuilding the same auth, admin panel, and CRM for every client. Ship a production-grade system on day one. Activate the extensions your client needs — invoice generation for one, procurement for another.

🏢 Enterprises & public institutions

Your data stays in your datacenter. Full RBAC, multitenancy, audit logs, and Romanian compliance built in. No SaaS vendor reading your business data.

🚀 Startups & indie developers

The infrastructure that used to cost €3,000/month in SaaS subscriptions, now runs on a €20 VPS. Focus on your product, not on gluing services together.

Your entire SaaS stack. On your server. Tonight.

One command installs everything: database, cache, storage, admin panel, AI, automation, mail, and compliance. No cloud account required.
