OutSystems and Mendix start at $36K+/year and trap your apps in a proprietary runtime. Weezzi gives you AI-native generation, real ownership of standard Java / Python / JavaScript code, and free self-hosting on Docker or Kubernetes.
We're not the fastest first-prototype tool — we're the platform that turns enterprise low-code into something you can actually own and operate after the demo.

OutSystems and Mendix don't just sell a development tool — they sell a runtime that your application depends on to execute. Stop paying the license, and your apps stop running. There's no "extract and walk away."
This is the thing the demo never shows: every line of business logic, every page, every workflow lives inside a black-box engine you don't own and can't replace.
Every enterprise low-code vendor will tell you they have AI now. The honest test: ask whether the AI generates the system, or whether the system was already there and the AI helps you click through it.
You still click through pages, drag entities into a UML-like canvas, and bind them to a proprietary process language. The AI suggests next steps inside that workflow.
Tables, queries, RBAC, REST + GraphQL, dashboards, multi-language fields, audit logs — all generated as standard code from a natural-language description.
Whatever the assistant generates is still expressed in the vendor's own language and only runs on the vendor's engine. AI accelerates lock-in.
Generated code is standard Java / Python / JavaScript with auto-generated REST + GraphQL + OpenAPI. Export the repository at any time.
The assistant uses general-purpose code models. It doesn't know your platform's specific patterns for RBAC, audit, multi-tenancy, or workflow.
Two decades of platform IP and a real production SaaS — Weezzi.com — feed the model with the patterns enterprise apps actually need.
Content, copy, and layout changes go through a developer because there's no runtime editing surface. AI doesn't fix that — it just speeds up the developer's part.
The Site Editor sits inside the deployed app. Authorized users edit content, layouts, and audience variations directly on production. Zero dev tickets.
Weezzi runs inside your own infrastructure. Annual license, included Builder seats, unlimited apps. BYOK AI. Source code escrow. Sovereignty-ready architecture for finance, healthcare, public sector, and defense-adjacent buyers.
Unlimited projects, unlimited apps, BYOK AI, source code escrow — all included at every level.
