Tesla owner tools.

Free tools for things Tesla owners actually look up — battery health, replacement cost, VIN decoding, charging and range. No accounts, no lead forms, nothing stored.

Questions

Are these tools free?

Yes, all of them, with no account required. The battery test asks you to authorise a read-only connection on Tesla's own login page; everything else runs entirely in your browser.

Do you store my data?

No. The calculators never send your inputs anywhere, and the VIN decoder queries NHTSA directly from your browser. The battery test reads your car once and discards the token.

Are you affiliated with Tesla?

No. This is an independent project, not affiliated with, endorsed by or connected to Tesla, Inc.

Independent fan project. Not affiliated with, endorsed by, or connected to Tesla, Inc. Figures are estimates for planning only, not a quote or a substitute for a service diagnosis.
