ADR-004: Reverse Proxy Selection — Caddy

Status: Accepted
Date: 2026-04-05
Deciders: Ezra (architect), Timmy Foundation
Scope: TLS termination and reverse proxy for Matrix/Conduit (#166, #183)

Context

Options for reverse proxy + TLS:

Caddy (auto-TLS, simple config)
Traefik (Docker-native, label-based)
Nginx (ubiquitous, more manual)

Decision

Use Caddy as the dedicated reverse proxy for Matrix services.

Consequences

Positive	Negative
Automatic ACME/Let's Encrypt	Less community Matrix-specific examples
Native `.well-known` + SRV support	New config language for ops team
No Docker label magic required
Clean separation from existing Traefik

Implementation
