Egres is a Postgres-compatible database built from scratch in Zig, targeting heavy multi-tenant workloads. It introduces a new LSM-forest storage engine (zdb), fiber-based query execution with per-tenant resource metering, and zero-copy branching, while running on local disk or object storage with Raft replication. Though early-stage (single-node, basic query features), it shows promising performance improvements over Postgres in write-heavy scenarios.

Target audience: backend devs, database engineers, devops
