Self-hosted, dev-first headless CMS that generates production-ready Flutter and Next.js apps from a single content model.
A startup from George, South Africa, founded by Anton Wentzel.
This page is designed to help you find out whether UnderPeaks is good and if it is the right choice for you.
Underpeaks is a developer-first headless CMS that generates production-ready Flutter and Next.js applications from a single content model. Founders define their data model once, and Underpeaks generates real, readable source code for both a mobile app and a web app from that same schema.
The platform supports five database backends — Supabase, PostgreSQL, MySQL, MongoDB, and Firebase — through a unified adapter layer, avoiding vendor lock-in. Underpeaks is available as Underpeaks Core, a free, open-source, self-hosted option, and as Underpeaks Studio, a managed hosted platform.
Underpeaks is built by a solo founder based in George, South Africa, for developers and agencies building both mobile and web applications from the same underlying data.
Listed in
Code Generation
Generate a full working Flutter app and a full working Next.js app from the same model, both wired to the same backend and staying in sync as the schema changes.
Data Modeling
Define your data as models with fields, types, and relationships, right inside the console, no separate schema file to maintain
Multi database support
Choose from five database backends, Supabase, Postgres, MySQL, MongoDB, or Firebase, through one consistent interface, so you are never locked into a single vendor.
Self hosted or managed
Run Underpeaks Core on your own infrastructure for free, or use Underpeaks Studio as a fully managed hosted platform, your choice.
Page Builder
Attach a model to a page and pick a template, list view, detail view, forms, and more, without writing frontend code by hand.
Dashboards and KPIs
Build charts and KPI cards from your own data models directly in the console, no separate analytics tool needed
State management choice
Pick Riverpod, Provider, or BLoC for generated Flutter code, and Zustand, React Query, or Jotai for generated Next.js code.
CLI tool
Log in, generate, and regenerate your apps from the command line as your schema evolves, with automatic dependency install.
Team access
Invite team members to a project with role based permissions.
Multi language support
The console and generated interfaces support multiple languages out of the box.
Most headless CMS tools give you a content API and an admin panel and leave the actual app building to you. Underpeaks goes further. You define your data model once and it generates a real working Flutter app and a real Next.js app from that same schema, not a template you have to fill in by hand. It also runs on five different databases through one adapter, and you can self host it completely free with no vendor lock in.
If you are building both a mobile app and a web app, Underpeaks saves you from building the same backend twice and keeping two codebases in sync every time something changes. Tools like Strapi, Payload and Directus stop at the API layer. FlutterFlow only covers mobile. Underpeaks covers both, and because it is not locked to one database, you are not stuck with whatever backend you started with.
Developers and small agencies who need to ship a mobile app and a web app from the same data without maintaining two separate backends. It is also a good fit for anyone who wants a self hosted CMS they actually own rather than renting access to their own data.
Underpeaks grew out of years of building the same kind of app over and over, a mobile version and a web version, each with its own backend, its own bugs, and its own drift from the other one over time. It became clear that the schema should be the single source of truth and everything else, the backend, the mobile app, the web app, should be generated from it instead of hand built twice.
Next.js and TypeScript power the hosted platform and the code generation engine. Flutter and Dart are one of the two generated app targets, with Next.js as the other. Supabase, Postgres, MySQL, MongoDB and Firebase are supported as database backends.
