I built an open-source FSD CAN Mod Tracker using SvelteKit and Tailwind

TL;DR · WeSearch summary

An open-source FSD CAN Mod Tracker has been developed using SvelteKit and Tailwind to monitor Tesla's FSD performance metrics. The application aims to provide a lightweight and responsive tool for automotive enthusiasts, addressing the lack of modern software solutions in this area. Key features include dynamic filtering of telemetry data and compatibility profiles across different Tesla hardware versions.

Key facts

▪The FSD CAN Mod Tracker was created to fill a gap in the software ecosystem for tracking automotive hardware modifications.
▪SvelteKit was chosen for its fast load times and reactivity, while Tailwind CSS was used for clean and readable dashboard layouts.
▪The application features an optimized client-side filtering system to manage dynamic CAN signals without database bottlenecks.
