I'm Phil, the creator of Graffiti - A web-based hyper-local anonymous message board (think YikYak but with no app required and the frontend aesthetics of Craigslist). It's meant to be pretty lightweight and run on almost anything with a browser and basic location services. It's built mostly in Python and Svelte, and currently running on a small Ubuntu VM + Postgres DB.

I originally started this project to leave geo-located comments for my brother and his friends around town since we all were fans of long meandering walks. I saw some friends-of-friends leave posts as well so I started to add additional features like:

-Replies: Start your message with "@@post_id" to get added to a thread below the parent post.

-Hashtags: Use a URL like https://graffitihere.com/#parks to see only comments including #parks.

-Distance filters: Currently Graffiti supports sorting distances between 400M and 5KM, though I'd like to build better ways to support more granular radii and other geo-based options.

-Tripcodes (optional): Use an imageboard-style tripcode to identify yourself to friends and build a reputation without having to keep the same username.

-Basic Search: Search the text of a post, username, or tripcode to filter posts.

There's plenty more to work on, and I'm really interested in what HN thinks would be useful features to prioritize next.

Most people probably won't see many posts outside major cities like Boston, New York, DC, etc. but we're always looking for new use-cases and to see how people interact with Graffiti so I encourage playing around!
