Apps first. Infrastructure underneath.

Flux is a self-hosted application foundry for building and operating small, durable software. Each app gets Postgres, migrations, backups, APIs, and demo-safe defaults from the same foundation.

Demo philosophy

Real interfaces. Safe demos.

Flux apps can expose a curated demo account with fake data, constrained actions, and no private secrets. The point is to let people understand the product by using it — including the Flux control plane itself and the demo-ready apps in the showcase above.

The foundation

One foundation. Many small apps.

  • Postgres by default

    Every app starts with durable relational storage.

  • Migrations that travel

    Plain SQL workflows for creating and evolving app schemas.

  • Restore-verified backups

    Backups are treated as useful only after they can be restored.

  • JWT-aware APIs

    PostgREST-style APIs without hand-written CRUD servers.

  • Demo-safe accounts

    Expose real interfaces with seeded data and locked-down permissions.

  • Dedicated or shared

    Start pooled, move dedicated when the app needs its own house.

Philosophy

Built for durable software.

A foundry for small durable apps.

Flux is the shared foundation underneath the apps above: Postgres, migrations, backups, JWT-aware APIs, demo mode, and deployment standards.

It is not trying to replace your database tools. It gives each app a reliable operating base.
