I built SlugPath — UCSC class search + schedule planner that checks whether you can actually make the walk between your classes
I'm a student at UCSC. Last quarter I scheduled a class at Oakes right after one on Science Hill because there was a 15 minute gap and that seemed fine, and then spent ten weeks half jogging across campus twice a week.
So I built a class planner that checks the walk.
It routes every gap between your classes over the real footpath network from OpenStreetMap instead of measuring in a straight line, which on this campus is off by anywhere from 18 to 56 percent because of the ravines. That Oakes leg looks like 739 meters and is 1153 on foot. You find out the gap doesn't fit before you enroll instead of during week 2.
The rest is a normal class search. Six quarters back and forward, filter by GE or department or day, live seat counts, RateMyProfessors scores on the results. When you add something with a lab or a section it ranks every option by whether you can actually get there in time, which is the part I use most.
There's also a campus map with all 489 buildings you can click around, walking directions that tell you if you're going to be late, and a GE checklist that fills itself in from your schedule.
Free, no login to search, works on mobile. The location stuff runs on your phone, I don't have a server to send it to. Happy to answer questions. If a class shows up in the wrong building please tell me, I match the room names by hand and that's where it breaks.
