Show HN: Grid Mapper – a routing tool for finding safe, fun ways through cities

Welcome to Grid Mapper

Grid Mapper is for anyone trying to get around town without relying on a car. Plan bike rides, walking routes, or transit trips that prioritize safety and exploration over just getting there fast. Create detailed routes with a focus on finding the fun stuff and avoiding the dangerous roads.

Who made this?

Just me, Jay. I built this whole thing in my free time because I wanted my friends to have a better way to get around the city safely and maybe stumble onto some adventures along the way.

What started as a simple routing tool snowballed into something more: a way to share cool spots, warn each other about rough intersections, and maybe help people connect over the routes and places they love. It's been my nights-and-weekends passion project for the past year, and it's eaten up way more evenings and weekends than I'd care to admit.

What's next?

There's a lot I want to add if I can keep this running:

• Native iOS and Android apps
• Custom routing profiles
• Better social features for finding riding buddies
• Whatever else makes sense based on how people use it

Hosting, API calls, and databases all cost money. I'm covering everything out of pocket to keep Grid Mapper running. If you find this useful and can chip in, it'd help a lot.
