Aurabase Cloud is a European Backend-as-a-Service platform built with Rust on PostgreSQL 17. It combines a dedicated database, Vault-backed authentication, S3 storage, Edge Functions, and a native MCP server in a sovereign infrastructure with zero reliance on American hyperscalers.
European AI-native Backend-as-a-Service. Built with Rust, dedicated PostgreSQL 17 per project, and full immunity to the US CLOUD Act.
The initial realization: in late 2025, the European software industry faced an artificial dilemma. On one hand, the velocity and developer experience of modern BaaS platforms (Supabase, Firebase), all bound by US jurisdiction and subject to extraterritorial CLOUD Act warrants. On the other hand, sovereign alternatives were often fragmented, slower, and cumbersome to deploy.
The low-level approach: we decided to start from a blank sheet in Rust. No Go, no Node.js, no JVM. Rust delivers sub-millisecond network latencies, eliminates all garbage collector pauses, and guarantees memory safety at compile-time. On this foundation, each project receives a dedicated PostgreSQL 17 cluster orchestrated by CloudNativePG.
A concrete reality in 2026: Aurabase SAS is today a profitable company, founded in Toulouse, operating 14 production microservices across three European datacenters. Your data never leaves the continent, and you retain total control through standard open protocols without proprietary forks.
