Tesla service is booked weeks out, but earlier slots open all day as people cancel — you just have to catch them. SlotWatch watches up to 3 Tesla service centers (including nearby ones you'd drive to) and emails you the moment an earlier appointment opens, so you reschedule in the Tesla app before it's gone. No Tesla login required — we never touch your account. One-time $24 for a 60-day watch, money-back guarantee. There's also a free open-source self-host version on GitHub.
