Self-Hosted Hardware Sizing Planner
Build a web-based planner that recommends CPU, RAM, storage, and GPU choices for common self-hosted stacks based on actual workloads, stream counts, and future expansion plans. The clearest demand is reducing uncertainty before users buy or repurpose hardware.
Why this matters
When you plan a small self-hosted server, the hardest part is not finding powerful hardware but knowing how little you can safely get away with. You see people claiming tiny systems are enough, while others warn about future upgrades, virtual machines, or side workloads. That leaves you guessing whether your spare parts are overkill, barely enough, or a trap that will need replacing soon. You want a practical answer tied to your exact mix of media, photos, downloads, and utility apps, plus a clear view of what changes if you add users or new services later.
- · Built for Individuals setting up or upgrading a home server for media, photos, DNS, downloads, and light utility services who want a right-sized build without wasting money or power..
- · Most likely monetization: SaaS subscription with freemium reports.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Free community advice may satisfy most users before they ever pay for planning.
- 2Accuracy may be too hard to maintain across changing apps, codecs, and hardware.
- 3Many users may only need the product once, reducing recurring revenue.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
This was the most repeated theme in the discussion. Roughly twenty-one mentions across the batches pointed to users feeling uncertain about how much hardware they really need, with many responses arguing that much smaller systems can run similar app stacks. Several comments also warned that future expansion changes the picture, showing a clear need for scenario-based sizing rather than one-size-fits-all advice.
