Free Tesla Tools

A growing collection of free Tesla utilities — designed for shoppers, owners, and the merely curious. No sign-up. No email. Each tool is backed by OwneDeals marketplace data, public Tesla production information, or both.

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 Is My Tesla Worth? — Enter model, year, trim, and mileage to estimate the current marketplace value of a used Tesla, with a realistic low-to-high range based on recently sold listings.

How the tools fit together

Start with the VIN decoder to understand the car's model year, factory, and likely Autopilot computer. Then estimate battery health from model, trim, age, and mileage. Finally, use the value estimator to compare the car against recent used-Tesla market data before you buy, sell, or negotiate.
