CrossPromo Club
I built CrossPromo Club, a free tool to help newsletters grow by promoting each other. It provides ways to find and connect with partners, and organize cross-promotions. There is also an automated cross-promotion feature that matches newsletters via a single link. There's a full demo - no signup needed. I made it because I was finding cross-promotion difficult for my own newsletter. I'd welcome any and all feedback.
CrossPromo Club launched on October 21, 2025 with 11 votes, #1,209 of 8,178 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.
What it does
Cross-promotion allows two newsletters to put each other in front of their respective audiences. This is an incredibly effective way to grow, but finding partners and organizing a fair exchange can be tricky. I built crosspromo.club to make it easier.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
