Serverless PostgreSQL.
Own Rust engine.
ScalixNova is a serverless PostgreSQL-compatible database built on our own Rust storage engine. Paxos-style WAL consensus, instant branching, point-in-time recovery, scale-to-zero, and a built-in query firewall.
Instant branching
Create database branches for previews, testing, or AI agent sandboxes. Fully isolated, with their own compute.
Point-in-time recovery
Rewind to within minutes of your latest write. WAL-based with configurable retention. Automated backups.
Scale to zero
Compute suspends when idle and you pay nothing while it sleeps. Wakes automatically on the next query.
Query firewall
Built-in SQL injection protection. Allowlist/blocklist query patterns. Per-tenant isolation.
Branch your database like code.
Every branch is a complete, writable copy of your database at a point in time — fully isolated, served by its own compute, created in seconds. Spin one up per pull request, per test run, or per AI agent, and drop it when you're done. Point-in-time recovery uses the same machinery: restore to within minutes of your latest write, anywhere in your retention window.
Billed only while it runs
Compute suspends when your database is idle and wakes on the next query. The meter follows the compute: active time draws from your credit pool at $0.095/CU-hour — idle time costs $0. A side project that's busy two hours a day pays for two hours a day.
Architecture
ScalixNova separates storage from compute. The storage engine materializes pages from the WAL log. The WAL keeper provides Paxos-style WAL consensus for durability. The compute layer runs PostgreSQL workers on your choice of 16, 17, or 18. All written in Rust, owned end to end.
