GuestLot vs Tessie

Tessie provides Tesla tracking, automation, Supercharging costs, service alerts, and battery health tools for fleet operators. Its drive history includes maps, analytics, and CSV exports.

GuestLot organizes a shop's care of a customer vehicle around one visit, from arrival to pickup. Its focus is the relationship between condition records, staff handoffs, authorized visibility, and an optional owner report.

LAST REVIEWED SEPTEMBER 4, 2026

Compare workflows, not just telemetry

Tessie is a relevant option for Tesla data and fleet operations. We have not established that it cannot support a shop's customer vehicles. Ask each vendor to demonstrate authorization, changing vehicle rosters, access closure, and the report a service advisor would retrieve later.

Questions to bring to a trial

Owners manage third-party permissions through Tesla. Keep each connection distinct, and do not ask an owner to share their existing Tessie or Tesla credentials with shop staff. Tesla explains how owners review and revoke app access.

Questions

Can a shop use Tessie to track customer cars?

Tessie offers Tesla tracking and fleet tools. Confirm with Tessie how customer authorization, rotating vehicles, access removal, and reporting work for your shop. We have not established that it cannot support that use. GuestLot focuses on a visit record with condition notes, staff handoffs, last-reported authorized location and its timestamp, and an optional owner report.

Should a shop consider Tessie for its own loaner cars?

Tessie is a relevant option to evaluate for Tesla loaners because it offers fleet tracking, automation, battery health, service alerts, and Supercharging cost information. Compare those capabilities with your operational requirements and current fleet terms. GuestLot's focus is documenting customer vehicles during a shop visit.

Can an owner run Tessie and authorize a shop at the same time?

Tesla supports separately authorized third-party applications, subject to vehicle compatibility and telemetry limits. The owner should grant the shop its own permission and review that connection in Tesla's access settings, rather than share an existing Tessie or Tesla login. Check connection status during setup; do not assume telemetry is available just because another application works.
