Show HN: SnackBase – Open-source, GxP-compliant back end for Python teams

I built this because I work in Healthcare and Life Sciences domain and was tired of spending months building the same "compliant" infrastructure (Audit Logs, Row-Level Security, PII Masking, Auth) before writing any actual product code.

The Problem: Existing BaaS tools (Supabase, Appwrite) are amazing, but they are hard to validate for GxP (FDA regulations) and often force you into a JS/Go ecosystem. I wanted something native to the Python tools I already use.

The Solution: SnackBase is a self-hosted Python (FastAPI + SQLAlchemy) backend that includes:

Compliance Core: Immutable audit logs with blockchain-style hashing (prev_hash) for integrity.

Native Python Hooks: You can write business logic in pure Python (no webhooks or JS runtimes required).

Clean Architecture: Strict separation of layers. No business logic in the API routes.

The Stack:

Python 3.12 + FastAPI

SQLAlchemy 2.0 (Async)

React 19 (Admin UI)

The demo resets every hour. I’d love feedback on the DSL implementation or the audit logging approach.
