The self-hosted Business OS
your entire company runs on
One binary. One command. Everything your company needs — database, auth, admin panel, REST API, real-time, offline sync, AI, automation flows, CRM, mail, document templates, approvals, edge functions, geospatial, POS, procurement, compliance, and more. Self-hosted on your server. No per-seat pricing. No vendor lock-in. No data leaving your infrastructure.

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.
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
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.
Simple API. Zero boilerplate.
REST, real-time, and TypeScript types — generated automatically from your schema.
React, Vue, and vanilla JS SDKs included · Offline sync with CRDT conflict resolution · WebSocket real-time
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)
Zveltio
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.
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.
