What is DX SaaS Template?

DX SaaS Template is a production-ready fullstack SaaS starter built entirely in Rust. It uses Dioxus 0.7 for both the server and the WASM client, compiled from a single codebase via Cargo feature flags.

Tip

Everything compiles to two binaries: a server (Axum + SSR) and a WASM client — from the same source tree.

Stack Overview

Dioxus 0.7

Fullstack Rust framework with SSR, hydration, server functions, and a React-like component model.

PostgreSQL

Relational database accessed with sqlx. Schema lives in migrations/ and is applied automatically on startup.

FerrisKey

Open-source, Rust-native OIDC identity provider with WebAuthn/passkey support. The template ships a custom login UI driving FerrisKey's REST API.

TailwindCSS + DaisyUI

Utility-first CSS with DaisyUI 5 component library. Dark theme by default.

Architecture

The project uses feature-gated compilation to split code between server and client:

#[cfg(feature = "server")] — Server-only code (PostgreSQL, Axum, sessions)
#[cfg(feature = "web")] — Client-only code (WASM bindings, browser APIs)

Server functions use the #[post("/api/...")] macro and can accept a session: auth::UserSession parameter for authentication.
