I ve been building HeliosDB Nano, a tiny, embedded SQL database designed for modern AI powered apps vectors, branching, time travel queries, Postgres/MySQL compatibility, all in a 47MB binary.
HeliosDB-Nano is a single 32MB embedded SQL database with native PostgreSQL & MySQL wire‑protocol compatibility, built‑in vector search (HNSW + PQ), full‑text search, git‑like branching, and time‑travel queries. It runs anywhere — local‑first apps, edge devices, AI agents, or serverless. No migrations, no drivers to rewrite. Use psql, mysql, REST, or any ORM — everything just works.
