Your own code, data and API endpoints. Fully yours.

The core of what you build
Four building blocks that return in every project. Further down you read how it works and what you get exactly.
Schema, API and auth, connected
- Your own private data that stays yours
- Secured endpoints, straight from your schema
- Export at any time, zero vendor lock-in
How it works
From database schema to a working API in four steps
As a developer you build on a platform that is fully yours: you define the data, NerrieBuilder generates a secured REST API, and you fill in the rest with your own code. No vendor lock-in, export whenever you want.
- 1
Define your data model
Create a dedicated, isolated data space per project with tables, columns and relations, through a clear visual data browser. You own the data, always.
- 2
Generate the REST API
Your schema automatically produces a secured REST/CRUD API: endpoints to read, create, update and delete, ready to use and validated.
- 3
Add your own code and auth
Write custom logic where you need it and set up authentication with registration, login and roles, without a third-party service or extra API key.
- 4
Deploy or export
Publish straight from the platform or export your own site and code. Nothing locks you in: zero vendor lock-in, no sealed black box.
Why developers choose NerrieBuilder
A stack you trust and fully own
Six reasons developers build on NerrieBuilder, from owning your data to full export.
Your own private data per project, no shared pool
Every project has its own private data. Data stays neatly separated and never leaves your environment unintentionally. Ideal for MVPs, internal tools and client projects.
Auto-generated REST API
Stop writing boilerplate. The secured REST endpoints come straight from your schema, validation included, so your frontend or app can connect right away.
Your own code where it counts
The platform imposes nothing on you. Add your own server logic, integrations and AI app generation wherever your use case calls for it.
Built-in auth, no third party
Registration, login and roles run on your own platform. No dependency on an external identity provider and no extra monthly costs.
No lock-in, always export
Export your own site and data at any time. You build on open technology and keep full control over where you migrate.
Fast from idea to prototype
Combine AI app generation with manual control: have the first concept generated, then refine every line yourself, on your terms.
Frequently asked questions
Questions from developers
Short answers to what developers ask most.
Can I add my own code to a project?
Yes. You add your own logic and functionality on top of your generated REST API and your project's own private data. You are not limited to ready-made blocks.
Am I locked into the platform, or can I export?
There is no vendor lock-in. You can export your own site and data at any time. You own your project and decide where you run it or migrate it to.
How does authentication work without an external service?
Auth is fully built in: registration, login and roles run on your own platform, without an external identity provider and without an extra API key. Everything stays within your environment.
