Best Databases for Axum (2026)
Compare the best database solutions for Axum. We review PostgreSQL options with SQLx and SeaORM integration.
Axum's async-first design pairs perfectly with async database crates. We've evaluated managed databases that work well with Rust's async ecosystem.
Why This Matters
Axum runs on tokio, requiring async database access. The right combination delivers excellent performance and ergonomic data access.
Key Considerations
SQLx Async
SQLx is async-native with compile-time SQL checking. Perfect match for Axum's tokio runtime.
State Extension
Pass database pool via Axum State or Extension. Clean access in handlers.
SeaORM
SeaORM provides async ORM built on SQLx. Good balance of convenience and performance.
Connection Pooling
SQLx includes async pooling. Configure max connections based on workload.
Transactions
Use SQLx transactions for multi-query operations. Async-friendly API.

Quick Start
use axum::{routing::get, Router, extract::State};
use sqlx::postgres::PgPoolOptions;
#[tokio::main]
async fn main() {
let pool = PgPoolOptions::new()
.max_connections(5)
.connect(&std::env::var("DATABASE_URL").unwrap())
.await
.unwrap();
let app = Router::new()
.route("/users", get(get_users))
.with_state(pool);
let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
axum::serve(listener, app).await.unwrap();
}
async fn get_users(State(pool): State<sqlx::PgPool>) -> String {
// Query database...
"users".to_string()
