Ask anyone who has been in the scene a while where you find out what's on, and the honest answer is usually some version of: you have to already know.
You know because a friend added you to a group. Because you saw a flyer in the one bar that puts them up. Because somebody posted a thread three months ago and you happened to scroll past it. That works fine if you're already in the room. It's useless to everybody else, which is most people. It's how someone can live in a city with a monthly munch for years and never hear about it.
Collr exists because I got tired of that being the answer.
The moment it changed was a conversation with WoofThePup. I was talking about letting people list their next events on their PawPup profile, so others could see where they'd be. He asked why I'd stop at pup events. Nobody was building an event database for us kinksters — so why not that? That was it. The event database was born, the name changed, and Collr became the new project.
Two problems, one site
Collr solves two problems, though they didn't arrive at the same time.
One is finding events — the problem that came later, and the one Collr is now really for. Munches, club nights, rubber socials, contests, workshops — all happening, almost none of it findable unless you were already plugged in.
The other is where it all started, and it came up constantly: you meet someone at a night, you get on, and they ask how to keep in touch. The easy answer is your Instagram. But your Instagram is also your family, your work, your old school friends. Handing that over isn't always what you want to do. What I wanted was a page I could give somebody that was just the kink side of me — my name, my links, what I'm into, what I'm going to — and nothing I'd rather they didn't see.
It started as PawPup
The first version wasn't Collr. It was PawPup: a link-in-bio service for pups. One page with all your kink socials on it, to hand to someone instead of reeling off your accounts one by one.
PawPup began as a private project around March 2026 — version 0.1.0 — and launched publicly in July as version 0.3. Early on, it was just me and a few others using it.
Then I built the event database, and opened the site up to every kink, and something became obvious. People weren't using it as a pup site with events bolted on. They were using it as a catalogue of what the whole scene was doing — leather, rubber, handlers, bears, riggers, furries, everybody turning up to the same nights.
A site called PawPup tells most of those people it's somebody else's. A name shouldn't be the thing that makes you feel you've walked into the wrong room. So on 26 August 2026 it became Collr: shorter, easier to say out loud, and named after the one thing the whole scene shares.
Your profile is your collar.
Nothing got thrown away in the move. Handles, links and themes all carried over, and pawpup.app still points here.
Why I rebuilt it from scratch
The original PawPup was a completely different kind of application. Bolting a proper event database onto it would have meant fighting it forever, so I rewrote the whole thing.
That's why the version number is still below 1.0, why so much has changed so quickly, and why the release notes read the way they do. The event database is the newest part of Collr, and honestly it's the reason for everything else.
The technical side has been the easy part. I've been building my own servers and infrastructure since I was about 13, so standing up everything Collr runs on wasn't the hard bit. Shaping Collr into what it is today — working out what it should be, who it's for, and what it should never do — has been the real challenge.
The rules I set myself
Building something for this community means getting a few things right before anything else. These were non-negotiable from the start:
- You aren't the part that gets indexed. No member profile shows up in search engines. Your page is something you hand to people, not something that surfaces when somebody googles your name.
- Going to something is private. Events show how many people are going, never who — unless you choose to be named.
- No feed, no inbox. Collr isn't somewhere to scroll or to get messaged by strangers. People reach you through whatever links you choose to put on your page.
- Collr never touches your money. No ticket sales, no booking fees, no commission. Listing an event is free and always will be.
- Gear, not nudity. The public site is safe to open with someone standing behind you. Explicit events are marked and kept off the open web, because one explicit page in a search index can get a whole domain filtered — and take every ordinary munch listing down with it.
If I had to pick one, it's privacy by default.
People using a site should never be the product.
I avoid using certain platforms for my own email for exactly that reason — there, you are the product — so why would I build Collr the same way?
The help I've had
Building Collr on my own has been difficult. I've had to lean on people to help me make the right decisions and guide me towards the place Collr is today. Without WoofThePup, and people like PupMax, Extortion, Dougal and Handler Dan, Collr could quite easily have been scrapped. Thank you, all of you. And thank you to Edinburgh Pups, our first Partner, for trusting Collr with their events.
Collr has always been a solo project, and today I'm still running it on my own and paying for it myself. Maybe one day I'll have help. For now, I keep asking the people close to me for advice and showing new ideas to others for feedback. I don't think it will ever be a paid job with its own staff — but I can dream.
Where you come in
The listings are only as good as what people know about, and plenty of the scene never makes it onto a website. Often the person who heard about it is the only way it gets found.
So:
- Know about something that isn't listed? If you know about a munch, a social or a night that isn't on Collr yet, add it — you don't have to be the organiser.
- Run events? Claim your page so the details stop being guessed at.
- Tired of handing out your Instagram? If you've ever wished you had something better to hand somebody at a bar than your Instagram, make yourself a page.
That's why I built it. Go and find something on.
