Undercroft helps homelab enthusiasts and small businesses build, harden, and own their infrastructure — off the cloud and on their terms.
Advisory to figure out what to build. Implementation to build it. Scope and price are agreed in writing before any work begins.
You know you want to self-host. You're not sure what to run, in what order, or why. You leave with a documented stack recommendation tailored to your hardware, goals, and skill level.
For small businesses evaluating self-hosted alternatives to SaaS and cloud services. Includes a threat model review, cost comparison, and vendor guidance — not just a list of tools.
Remote implementation of a defined homelab stack. Proxmox, TrueNAS, Home Assistant, Jellyfin, CrowdSec — built, tested, and handed off with documentation you can actually use.
Remote implementation for small business environments. Security hardening, monitoring baseline, backup configuration, and a runbook your team can actually follow.
Undercroft is a one-person infrastructure consulting practice run by Tanner Miller. The work focuses on helping people and small businesses take control of their infrastructure — self-hosted, Linux-first, and built to last.
The homelab and self-hosted space has matured. Proxmox, TrueNAS, Wazuh, CrowdSec — these aren't hobbyist toys anymore. They're production-grade tools that deserve production-grade setup. That's what Undercroft delivers.
No managed services. No upsells. Scoped work, documented handoffs, and infrastructure you actually understand when the engagement ends.
Describe what you're working with and what you're trying to solve. No commitment, no sales call — just a conversation to see if there's a fit.
