My name is Tim, and I'm a both a DM and web developer.
I find the Pathfinder Society scenarios to be incredible books filled with amazing stories, locations, events, NPCs and illustrations. I often use them as-is, or as a source of inspiration for my own homebrew scenarios. Each time I read one, it gives me tons of ideas to incorporate into my own game.
But there are so many of them!
I often need to find scenarios dealing with a specific location (like a prison, a desert, or a boat). Or to filter out scenarios that are high-level or low-level for my current party of adventurers. Finally, after reading a bunch of them, I also have some favorite authors, and would rather read those in priority.
All that lead me to building the website you're using today. Initially it was just for me, but I thought it might help other DMs out there, so I made it public.
The data is then pushed to Algolia (an awesome service that provides lightning fast search capabilities). I used to work at Algolia, so building the search UI around the data was right in my comfort zone. The code for this website is also Open-Source and available on GitHub. Please, send any feedback, bug report or feature request there.
I don't know. Let me know on Twitter if there's any feature you'd like me to add, or any bugs you encountered.
