Source-owned infrastructure for multi-tenant Go applications.
Amsonia Core is the first public component: an Apache-2.0 authorization foundation built with Go, PostgreSQL RLS, and a React management console.
Open-source foundationReleasedTenant-safe authorization for Go and PostgreSQL teams.
Core keeps tenant membership, delegated policy, administrator sessions, audit history, and PostgreSQL row isolation in source you can run and review.
Only released products appear here. New components enter the system when their source, documentation, and support boundary are ready.
Amsonia Core packages the boundary that is expensive to retrofit later: tenant membership, delegated RBAC, signed PostgreSQL row-level security, authenticated administrator sessions, and an auditable policy history.
Open-source foundation inside Amsonia, implemented in Go with PostgreSQL and a React management console.
Every technical claim on this site is tied to public code, a versioned contract, a negative test, or a maintained document in Amsonia Core.
