Architecture Overview
Stack
| Component | Technology |
|---|---|
| Backend | Django 5 + HTMX |
| Database | PostgreSQL 16 |
| SCM | Fossil |
| Proxy | Caddy |
| Backups | Litestream → S3 |
| Jobs | Celery + Redis |
How It Works
Each Fossil repository is a single .fossil SQLite file. Caddy routes subdomain requests to the Fossil server. Django provides the management UI. Litestream continuously replicates repo files to S3.
