Features & Specs

  1. 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.

  2. Data Modeling

    Define your data as models with fields, types, and relationships, right inside the console, no separate schema file to maintain

  3. 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.

  4. 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.

  5. 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.

  6. Dashboards and KPIs

    Build charts and KPI cards from your own data models directly in the console, no separate analytics tool needed

  7. State management choice

    Pick Riverpod, Provider, or BLoC for generated Flutter code, and Zustand, React Query, or Jotai for generated Next.js code.

  8. CLI tool

    Log in, generate, and regenerate your apps from the command line as your schema evolves, with automatic dependency install.

Questions & Answers

As answered by people managing UnderPeaks.
  1. What makes UnderPeaks unique?

    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.

  2. Why should a person choose UnderPeaks over its competitors?

    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.

  3. How would you describe the primary audience of UnderPeaks?

    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.

  4. What's the story behind UnderPeaks?

    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.

  5. Which are the primary technologies used for building UnderPeaks?

    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.
