K8s Architecture Decision Advisor for Homelabs
An interactive web tool that asks home lab operators about their goals, constraints (budget, hardware, power), and use cases, then recommends a K3s/K8s architecture with specific configuration guidance — including whether dedicated master nodes make sense, HA setup recommendations, and cost-optimized hardware choices.
Why this matters
You want to set up a Kubernetes cluster at home but you're unsure whether you need dedicated master nodes, how many nodes to buy, or whether HA is even worth it for your use case. You ask online and get contradictory advice — one person says dedicated masters are best practice, another says they're unnecessary because K3s makes the master schedulable, and someone else suggests just using VMs. You don't have the experience to evaluate which advice applies to your situation, and the wrong choice means wasting money on hardware you don't need.
- · Built for Home lab operators and self-hosting beginners who are planning a Kubernetes setup and are confused about which architecture approach is right for their specific constraints.
- · Most likely monetization: Freemium with affiliate hardware recommendations and paid personalized consultation reports.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The tool provides one-time value — users get their answer and never return, making it hard to build sustainable recurring revenue
- 2The information already exists for free across numerous blog posts and community discussions, just not in a consolidated interactive format
- 3Affiliate hardware links may generate minimal revenue given the low frequency of hardware purchases in this audience
Evidence Summary
How AI synthesized this insight — no verbatim quotes
About 5 commenters discuss what the right K8s architecture approach is, with conflicting views. One shares industry experience about on-prem VMs vs cloud managed vs bare metal. Another says dedicated masters aren't needed since K3s masters are schedulable. The poster admits their question was really about best practice, not just feasibility. Multiple commenters suggest cheaper alternatives like adding a third Pi or using VMs. This reveals clear confusion about which architecture approach fits specific constraints, with no tool available to provide personalized guidance.
