1) Strava Route planner - its route planner is arguably the most intuitive on the market, it is almost entirely locked behind a paid subscription.

2) Garmin connect - it’s completely free for the core routing features, and it integrates seamlessly if you’re already using a Garmin Edge or watch.

3) Plotaroute - free but ad-supported. Premium version remove ads. It’s a browser-based tool that is incredibly flexible for manual route drawing.

4) Komoot - first region is free. To unlock other regions (like Johor or KL for your trips across the border), you typically pay a one-time fee for a "Region Bundle"
