GPS trackers to prevent theft?

I recently had a scare when my Kia was stolen from my driveway last month. Thankfully, it was recovered, but the experience left me anxious about my vehicle's security. I'm now looking into real-time car theft alert and GPS tracking solutions to prevent this from happening again.​

Has anyone here used a GPS tracker that provides instant alerts and real-time tracking? I'm particularly interested in devices that don't require additional hardware or complex installations. Any recommendations or experiences would be greatly appreciated!​

Thanks in advance for your help.
