Find the expensive hardware mistakes while they're still cheap.
Four tools built from the questions hardware founders ask us most. Is this ready for production? What certifications does it need? What will a unit really cost? How long will the battery last? Results on screen in minutes, with a link you can send your cofounder.
Built by the engineers behind an industrial gas router with 50+ valves under real-time safety control, an armored EV battery system and a small-batch respirator assembly line. See the work →
Production readiness score
Find out how close your hardware really is to production, and what will stall it.
- 0–100 score across six areas
- Your real stage: EVT, DVT or PVT-ready
- Top three risks, each with a next action
Certification map
See which certifications your product needs in each market before a lab tells you.
- FCC, ISED, CE/UKCA, RCM, MIC/PSE, UL, UN 38.3…
- Why each one applies to your product
- Primary sources linked for every rule
Unit cost & NRE model
See what a unit really costs delivered, and how tooling and setup costs amortize with volume.
- Landed cost per unit vs volume
- Gross margin for DTC or retail
- Break-even volume, and where tooling stops mattering
Battery life calculator
Estimate runtime from your duty cycle, before you pick a cell or promise a number on the box.
- Runtime from your duty cycle, regulator and chemistry
- Which state eats your power budget
- Assumptions shown, not hidden
Why free
The cheapest time to find a problem is before you pay for it.
A missed certification, an unknown landed cost or an untested factory process usually surfaces after the tooling deposit. These tools surface them first. If one shows a gap we can help close, you'll know where to find us. If not, you've spent three minutes.
- 01No email gate. The full result is on screen. Email is optional, for a saved copy or a free review.
- 02Assumptions shown. Every estimate says what it assumes and how the number is built.
- 03Sources cited. Regulatory rules link to the primary text: eCFR, EUR-Lex, ISED, ACMA, METI.
- 04Not legal advice. They tell you what to ask; an accredited lab or your counsel gives the final answer.
