Severity · 25% · 20 pts · XPS quality80

LLM/mock judgment of intensity from title/summary text — not ops or ticket data. Maps to XPS quality (with willingness to pay).

Willingness to pay · 30% · 22.5 pts · XPS quality75

LLM/mock purchase-intent guess from text — not invoices, surveys, or paid seats. Maps to XPS quality.

Trend · 10% · 6 pts · XPS novelty60

Heuristic/scaffold (often random or fixed on insert) — not a verified mention trajectory. Maps to XPS novelty.

Market size · 10% · 6 pts · XPS relevance60

Heuristic/scaffold (often random or fixed) — not TAM research. Maps to XPS relevance (with frequency).

“Show HN: Beacon (open source) – Built after AWS billed me 700% more for RDS This is a great example of how unpredictable AWS billing can derail projects. I&#x27;ve seen this exact scenario play out at multiple companies - sudden 700%+ cost spikes that force engineering teams to become billing experts instead of building product.<p>A few learnings from teams I&#x27;ve worked with who faced similar issues:<p>1. RDS cost surprises often come from I&#x2F;O charges that aren&#x27;t obvious upfront. Moving to reserved instances helps, but doesn&#x27;t solve sudden usage spikes.<p>2. The &quot;build your own monitoring&quot; approach works but has hidden costs - engineer time, maintenance, alert fatigue, etc.<p>3. Many teams find that automated cloud optimization platforms (like CloudExpat, Spot.io, or CAST AI) can reduce costs 60-90% without the engineering overhead.<p>For anyone spending $10k+&#x2F;month on AWS&#x2F;Azure&#x2F;GCP, it&#x27;s usually worth getting a free cost analysis. Even if you don&#x27;t use a platform, they&#x27;ll often reveal billing patterns you didn&#x27;t know existed.<p>Your Beacon project looks solid for self-hosters though - great work turning a painful experience into something useful!”
