Free Tesla Tools

A growing collection of free Tesla utilities — designed for shoppers, owners, and the merely curious. No sign-up. No email. The tools are funded by display advertising on this site so that we can keep them open to everyone.

Available tools

• Tesla VIN Decoder & Autopilot Hardware Checker — Paste up to 10 Tesla VINs to see model year, plant, body style, and an HW1 / HW2 / HW2.5 / HW3 / HW4 estimate with a confidence label and a plain-English explanation.
• Tesla Battery Health & Range Estimator — Enter model, year, trim, and mileage to estimate a used Tesla's remaining battery capacity (battery health %) and its real-world range at full charge, with the original EPA-rated range for comparison.

What's next

We are working on a used-Tesla payment calculator (based on real OwneDeals comparable sales) and a Supercharger-cost-of-ownership calculator. Have a tool idea? Tell us what you'd find useful.
