Questions & Answers

As answered by people managing Free Plate Check and JavaScript Knowledge Map.

What makes your product unique?

Free Plate Check's answer

It's completely free with no signup, no account, and no paywall. Most vehicle check services either charge per check or hide useful data behind a registration wall. Free Plate Check gives you everything — MOT history, tax status, mileage records, ULEZ compliance, recall alerts and valuations — instantly, with no strings attached.

Why should a person choose your product over its competitors?

Free Plate Check's answer

Most competitors charge £5-£20 per check or require you to create an account before seeing any results. Free Plate Check provides comprehensive vehicle data from official DVLA and DVSA sources at no cost. You get the same government data that paid services use, presented clearly with practical insights like MOT expiry warnings and mileage anomaly detection.

How would you describe the primary audience of your product?

Free Plate Check's answer

Anyone in the UK who needs vehicle information. That includes used car buyers doing due diligence before purchasing, current car owners keeping track of MOT and tax dates, and sellers wanting to present their vehicle's history to potential buyers. It's also useful for fleet managers and anyone checking a vehicle's ULEZ compliance before driving into a Clean Air Zone.

What's the story behind your product?

Free Plate Check's answer

It started as a side project after realising that the DVLA and DVSA make vehicle data freely available through their APIs, yet most car check websites charge for access to the same public information. Free Plate Check was built to make that data accessible to everyone in a clean, easy-to-use format — no fees, no signup, no catch.

Which are the primary technologies used for building your product?

Free Plate Check's answer

Next.js for the frontend and server-side rendering, deployed on Vercel. It integrates directly with the DVLA Vehicle Enquiry API and DVSA MOT History API, with Supabase for caching and rate limiting.

    I was looking for a comprehensive report on a car I wanted to purchase and came across this site. It provides far more than every other site I have seen. And it's laid out beautifully. Would thoroughly recommend.
