Fastest-growing OSS startups for every quarter since Q2 2020
Over five years ago, I started publishing the top 20 trending open-source startups every quarter, based on their relative GitHub star growth — the ROSS Index. It has become quite handy for 60K+ developers, founders, and other OSS fans who have visited it to date. To make it even more convenient, we have just open-sourced its full dataset for 22 past quarters, including the fresh list for Q3 2025, so everyone can play with it — for instance, analyze what happened with startups from the first quarters. Given that in the very first index issue (Q2 2020), 5 out of 20 early-stage startups (n8n,…

In the maker’s words, at launch
Over five years ago, I started publishing the top 20 trending open-source startups every quarter, based on their relative GitHub star growth — the ROSS Index. It has become quite handy for 60K+ developers, founders, and other OSS fans who have visited it to date. To make it even more convenient, we have just open-sourced its full dataset for 22 past quarters, including the fresh list for Q3 2025, so everyone can play with it — for instance, analyze what happened with startups from the first quarters. Given that in the very first index issue (Q2 2020), 5 out of 20 early-stage startups (n8n, Hugging Face, Streamlit, Cortex Labs, Framer) eventually reached $0.5B+ valuation, it seems like an interesting area for research.

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…

Hey 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…
