The open-source platform for
any business application
Zveltio is a self-hosted foundation that ships the core every business app needs — collections, auth, permissions, real-time, AI, audit trail, automation — into a single binary with an extensible plugin system.
Use the included plugins to replace your SaaS stack. Build custom applications on the core. Or do both.

no migration
No per-seat fees
self-hosted
Build any business app — self-hosted, modern, yours
The engine ships with everything every business application needs. Activate plugins for common domains, or build custom logic on top.
Single Binary
One executable. Bun + Hono. Runs on a €20 VPS, on Proxmox LXC, or in Docker — no cloud account required.
Zero-Downtime DDL
Ghost Tables algorithm: alter schema on 5M-row tables while users are active. No locks, no maintenance windows.
Schema Branching
Branch your entire schema like Git. One-click staging environments — diff, test, merge. Built into the platform.
AI-Native
OpenAI / Anthropic / Ollama / Azure. Schema generation, semantic search, text-to-SQL, all native.
Bring Your Own DB
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.
Audit + GDPR
Every write logged (who, what, when, where). One-click GDPR data export and right-to-erasure.
Plugin Marketplace
54 first-party plugins, reviewed before publish. Third-party listings open after beta exits.
Proxmox + PBS
First-class Proxmox LXC deployment with Proxmox Backup Server hooks. Application-consistent backups, no extra tooling.
Your business stack, on your hardware.
Build it or borrow it.

Build a vertical product
Build legal-tech, healthcare-CRM, real-estate-management, ag-tech, education-LMS, fintech-back-office. Don't rewrite auth + admin + permissions + audit for the 47th time.
The engine handles plumbing; you focus on domain logic. A typical vertical SaaS skeleton — collections + auth + RLS + admin UI + REST API — is 0 lines of code in Zveltio.
Custom internal tools
Intranet portals. Employee dashboards. Client area portals. Document workflows. Internal analytics. Approval chains tied to your specific process.
Self-hosted, owned, modifiable. No SaaS vendor reading your operations data.
Stop paying per seat. Start owning the platform.
Software agencies & consultancies
Reduce boilerplate 60-70%. Ship custom client apps in weeks, not months. Self-hosted means clients own what you build.

Vertical SaaS founders
Legal-tech, real-estate, healthcare, ag-tech, education. Don't rewrite auth + admin + permissions for the 47th time.

The platform behind your business.
Build it. Plug it in. Own it forever.
One installer puts the engine on your server. Plugins extend it from a growing marketplace. Custom code lives next to the core. MIT-licensed. Yours.
