Caddy is the simplest reverse proxy for self-hosted services. It gets and renews TLS certificates from Let’s Encrypt with zero config. Install the static binary, write a Caddyfile with three lines per service, and Caddy handles HTTPS, HTTP/2, OCSP stapling, and renewal on its own. That replaces hundreds of lines of Nginx config and separate Certbot cron jobs.

If you run even a handful of services on a home server or VPS, a reverse proxy with proper TLS is non-negotiable. Caddy makes this painless, so there’s no excuse to skip it.

Yes, a plain Debian 12 or Fedora Server install on cheap x86 hardware, or a Raspberry Pi 5, makes a better router than most consumer gear. It often beats boxes that cost twice as much. You need two network interfaces, a few config files, and about two hours. The result is a gateway with a real stateful firewall via nftables , proper DNS and DHCP from dnsmasq , and traffic shaping that works through CAKE SQM. Every config is plain text you can track in Git.

To connect two remote LANs over WireGuard , you configure a WireGuard peer on one gateway device at each site, set AllowedIPs to include the remote site’s subnet, enable IP forwarding on both gateways, and add routing so LAN clients send cross-site traffic through the tunnel. Once configured, every device on either LAN can reach devices on the other LAN transparently - no VPN client installation on individual machines. A single UDP port open on at least one side is all you need.

Use Home Assistant ’s built-in packages system. Instead of one giant configuration.yaml that grows into a 2,000-line beast, packages let you split YAML by function: packages/lighting.yaml, packages/climate.yaml, packages/security.yaml, and so on. Each file can hold any mix of automations, sensors, scripts, input helpers, and templates. To tweak your thermostat logic, you open packages/climate.yaml. Nothing else.

As of Home Assistant 2026.4, packages support every integration domain, !secret references, Jinja2 templates, and nested subfolders. The rest of this post walks through setup, migration, design patterns, and Git workflows that make packages practical for a real smart home.

Tailscale builds a private WireGuard -based mesh VPN across all your devices with almost no setup. You install the client on each machine and sign in with your identity provider. Every device then gets a stable 100.x.y.z IP that works no matter the NAT, firewalls, or network changes. Tailscale v1.96 adds ACL tags for per-device policy, exit nodes, subnet routers, and MagicDNS for hostname lookups. For homelabbers, it is the easiest way to link a server, cloud VPS, phone, and laptop into one network.

PCIe bifurcation splits one physical PCIe x16 slot into several independent x4 (or x8) logical slots. That lets you fit two to four NVMe drives on one cheap adapter card, often just $20 to $50 for a passive model. Bifurcation is a CPU-level feature, not the job of an extra chip, so each drive gets its own lanes with zero overhead. A Gen4 x4 link delivers around 7 GB/s per drive , the same bandwidth as a standard motherboard M.2 slot. Out of M.2 slots but still have a free x16 PCIe slot? Bifurcation is one of the cheapest ways to add more NVMe storage.
