Your finance team would never approve renting laptops at a 300% markup. So why are you doing it with test devices?
Every month, engineering teams wire thousands of dollars to cloud testing providers for infrastructure they could own outright. Not because the cloud is better—but because nobody ran the numbers.
Let's run them.
The Math Your CFO Needs to See
Here is the actual cost breakdown for a standard 10-device lab:
| Cost Factor | Cloud (BrowserStack) | DeviceLab (Own Hardware) |
|---|---|---|
| Monthly cost | $2,500 | $891 (9 paid + 1 free) |
| Annual cost | $30,000 | $10,692 |
| Hardware (one-time) | $0 | $779 (Mac Mini + Hub + Cables) |
| Year 1 Total | $30,000 | $11,471 |
| Year 2 Total | $60,000 | $22,163 |
| Year 3 Total | $90,000 | $32,855 |
3-Year Savings: $57,145
That is $19,000+ per year saved on just 10 phones. Not a rounding error—enough to hire a junior engineer or upgrade every developer's laptop.
The 100-Device Reality
When you scale this to a full enterprise lab, the "Cloud Tax" becomes indefensible:
| Devices | Cloud Cost (3 Years) | DeviceLab Cost (3 Years) | You Keep |
|---|---|---|---|
| 10 | $90,000 | $32,855 | $57,145 |
| 25 | $225,000 | $83,940 | $141,060 |
| 50 | $450,000 | $167,880 | $282,120 |
| 100 | $900,000 | $335,760 | $564,240 |
At 100 devices, you are saving $188,000 per year. That is pure bottom-line profit.
"But We Need Instant Access to Any Device"
No, you don't.
Look at your test logs. 90% of your runs happen on the same 15 devices. The iPhone 15. The Galaxy S24. The Pixel 8. Your core regression suite does not need a Finnish Nokia from 2019.
The smart play is not all-or-nothing. It is the Hybrid Model:
┌─────────────────────────────────┐ ┌──────────────┐
│ │ │ │
│ CORE REGRESSION (90%) │ │ EDGE CASES │
│ │ │ (10%) │
│ DeviceLab │ │ BrowserStack │
│ │ │ │
│ $0/minute │ │ $$$/minute │
│ │ │ │
│ • Daily CI/CD │ │ • Rare OS │
│ • Smoke tests │ │ • Old devices│
│ • Regression suite │ │ • One-offs │
│ │ │ │
└─────────────────────────────────┘ └──────────────┘
Keep your cloud subscription for the weird stuff. Run your daily workload on hardware you own.
You are not killing your safety net. You are right-sizing it.
The Hidden Costs Nobody Talks About
The Parallelism Tax
Want to run 10 tests simultaneously? That is 10 parallel slots. At $250 each. Per month.
Your developers are waiting in queues because you are rationing access to save money. That is not a testing problem—it is a procurement problem.
With owned devices, parallelism is free. Run 50 tests on 50 devices. No slots. No queues. No artificial scarcity.
The Latency Problem
Cloud devices sit in Virginia or Frankfurt. Your staging server sits in your VPC.
Every test command travels: Your CI → Cloud Provider → Their Device → Back.
That is 100-500ms of latency per interaction. Multiply by thousands of UI actions. Your test suite is slow because of geography, not code.
Local devices respond in under 50ms. That is not incrementally better—it is a different experience entirely.
The Security Liability
Every test run uploads your unreleased binary to someone else's server. Your staging credentials. Your test data. Your intellectual property.
"But they're SOC2 compliant!"
SOC2 means they have security policies. It does not mean your data is not sitting on shared infrastructure, passing through their network, visible in their logs.
With on-premise devices, your binary never leaves your building. Zero trust is not a marketing term—it is an architecture decision.
What You Actually Need to Buy
Stop overcomplicating this. A production-ready 10-device lab costs less than one month of cloud:
| Item | Product | Cost |
|---|---|---|
| Host | Mac Mini M4 (16GB) | $599 |
| USB Hub | Sabrent HB-BU10 | $60 |
| Cables | Anker PowerLine III (10x) | $120 |
| Total | $779 |
No server room. No dedicated IT. No ongoing hardware maintenance contracts.
Plug it in. Install DeviceLab. Run tests.

The Objections (And Why They're Wrong)
"We don't have DevOps bandwidth for hardware"
Modern device labs are software-defined. DeviceLab auto-recovers disconnected devices, monitors battery health, and reboots hung phones. You are not hiring someone to babysit USB cables.
"What about device coverage?"
You are already testing on 15 devices. You will still test on 15 devices. The only difference is who owns them.
Buy refurbished. An iPhone 13 tests iOS apps just fine—and costs $400 instead of $1,200.
"Our enterprise security team won't approve random hardware"
They will approve it faster than they will approve uploading proprietary code to a third-party cloud. On-prem is the security team's preferred answer.
"Scaling is easier in the cloud"
Scaling cloud costs is easy. Just add more zeros to the invoice.
Scaling owned hardware means buying another Mac Mini. Once. Then it is yours forever.
Calculate Your Exact Savings
Every team is different. Here is how to run your own numbers:
- Count your current cloud devices (check your invoice)
- Multiply by $250/month (conservative cloud cost)
- Compare to DeviceLab: $99/device/month + one-time hardware
- Calculate 3-year difference
Or use this formula:
Annual Savings = (Devices × $250 × 12) - (Devices × $99 × 12) - Hardware Cost
For 25 devices with $2,800 hardware:
= (25 × $250 × 12) - (25 × $99 × 12) - $2,800
= $75,000 - $29,700 - $2,800
= $42,500 saved in Year 1
Year 2 and beyond? That $2,800 hardware cost disappears. You save $45,300 every year after.
Who Already Made the Switch
Teams running 50+ devices on DeviceLab instead of cloud:
- Fintech apps that cannot upload binaries to third-party servers
- Healthcare platforms with HIPAA data in test scenarios
- Enterprise teams tired of explaining cloud costs to finance
- Startups that refused to accept "testing is expensive" as a given
They did not switch because they hate BrowserStack. They switched because the math stopped making sense.
What Happens Next
Option 1: Keep paying the cloud tax. Budget $30,000/year for 10 devices. Explain to finance why testing costs more than the developers writing the tests.
Option 2: Spend $779 on hardware. Pay $99/device/month. Save $18,500+ in Year 1 alone. Redeploy that budget to hiring, features, or literally anything else.
The cloud made sense in 2015 when the alternative was building a data center. It does not make sense in 2025 when the alternative is a Mac Mini under your desk.
Frequently Asked Questions
How much does BrowserStack cost per device?
BrowserStack charges approximately $250-300 per device per month for dedicated real device access, translating to $3,000+ per device annually.
What is a cloud exit in mobile testing?
A cloud exit is the strategic move from renting cloud-based device testing infrastructure to owning your own private device lab, reducing costs by over 60%.
How long does it take to recoup device lab hardware costs?
Most teams break even within 2 months. A 10-device lab saves over $1,600/month compared to cloud rentals, paying off the hardware investment in roughly 45 days.
What hardware do I need to build a 10-device lab?
A Mac Mini M4 ($599), Sabrent HB-BU10 USB hub ($60), and 10 Anker cables ($120). Total: $779 one-time cost.
Is the hybrid model better than full cloud exit?
For many teams, yes. Keep 10% of devices on cloud for rare OS versions and edge cases, move 90% of daily regression to owned hardware. You get cost savings without losing coverage.
Your test infrastructure is either an asset or an expense. Renting makes it an expense. Owning makes it an asset. The math is simple. The decision should be too.
