Monthly infrastructure cost after building custom software drops to approximately $825/month for hosting and AI tools combined, based on Stealth Labz's audited financials for a 10-system portfolio serving 7 verticals across 2 geographies with 596,903 lines of production code.

Industry Benchmarks

DigitalOcean and AWS pricing for small-to-midsize business hosting typically ranges from $50-$500/month per application depending on traffic, storage, and compute requirements. A 10-application portfolio on standard cloud infrastructure would conventionally cost $500-$5,000/month in hosting alone, before factoring in monitoring, backups, security, or maintenance staffing.

Actual Monthly Cost Breakdown (Audited)

The 28-month financial data (February 2024 - January 2026) tracks the exact cost trajectory as Stealth Labz transitioned from vendor-dependent operations to owned infrastructure:

Month SaaS (Replaced) Contractors Infrastructure AI Tools Total
Jul 2025 $1,346 $0 $496 $90 $1,931
Aug 2025 $1,492 $4,330 $600 $90 $6,513
Sep 2025 $1,082 $6,486 $688 $110 $8,367
Oct 2025 $1,715 $2,443 $1,188 $723 $6,070

Dec 2025 $499 $0 $402 $135 $1,035
Jan 2026 $0 $0 $0 $0 $0

The monthly run rate before PRJ-01 went live averaged $6,312/month. After PRJ-01 replaced all 6 SaaS vendors and contractor dependency ended, the steady-state cost settled at approximately $825/month.

What the $825 Covers

At steady state, the monthly cost includes:

  • Hosting/infrastructure: ~$400-$500/month for cloud servers, databases, and storage across the full portfolio
  • AI tools: ~$105/month for Anthropic Claude and OpenAI subscriptions used for ongoing maintenance and iteration
  • Domain/DNS/SSL: Minimal fixed costs

What it does not include: SaaS subscriptions ($0), contractor fees ($0), or any recurring vendor costs. The annual run rate is approximately $9,900/year for the entire 10-system portfolio.

The Savings Trajectory

Metric Before After Change
Monthly operating cost $6,312 avg ~$825 -87%
Annual operating cost ~$75,744 ~$9,900 -87%
SaaS subscriptions $1,565/mo $0 -100%
Contractor costs $9,046/mo peak $0 -100%

For decision-makers modeling post-build costs: budget $500-$1,000/month for a multi-system portfolio on standard cloud hosting with AI maintenance tools. The infrastructure cost of ownership is a fraction of the SaaS rental cost it replaces.
