It lets you pick your framework and stack, then generates a tailored .cursorrules file for your project. No signup, no tracking, runs entirely in the browser.
Why free: I was collecting cursor rules for different frameworks anyway (React, Go, Rust, FastAPI, etc.) and realized the hardest part for most people is not finding rules — it is combining them correctly for a multi-framework project. A Next.js + Tailwind + Prisma project needs different rules than a pure React SPA.
Cost to operate is basically zero — it is a static site on Surge.sh. The content took real effort though, I reviewed cursor rules across 16 frameworks to extract what actually improves AI output versus what is just noise.
No monetization plan for the generator itself. I do sell a more comprehensive collection with project-specific templates on Gumroad, but the generator covers the most common use cases for free.

- All my projects are hosted on Vercel (and/or Cloudflare), within their free/hobby tiers.
- No plans to monetize any of them.
- I find it more interesting to work on projects that are used by someone, whether that is myself or others.
- These projects are for learning. I would love to make a living developing novel UX like these projects. Perhaps a future project, or through someone I meet via these projects. (I did get a GitHub sponsorship, which was partially made possible by my work on these projects.)
Has a tip jar in case anyone wants to support the effort
I'm building Tech Talks Weekly[1], a free newsletter where my readers get one email per week with all the latest Software Engineering conference talks and podcasts[1] published that week.
Recently, I've released a paid tier[2] where my subscribers additionally get:
1. Access to my internal database of all the talks and podcasts since 2020 (+48,000 in total) where they can search, filter, sort, and group by title, conference/podcast, view count, date, and duration.
2. See the list of the most-watched talks over the last 7, 30, 90 days, 6 months, and 12 months based on number of views.
3. Get category-based view of new talks & podcasts by tech stack, language, and domain (Software Architecture, Backend, Frontend, Full Stack, Data, ML, DevOps, Security, Leadership and every major language & ecosystem).
It costs almost nothing besides the domain and Claude subscription to improve my tooling.

The blog has no monetization or advertising. Right now, I am only investing my time in creating content and looking for founders to talk to. My plan is to build an audience over the next few years and then offer consulting services.
It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
The core product is free 100%. I'm building a paid version for lawyers/law firms (https://plus.fillvisa.com/).
In my case, building a free product helps in: - genuinely helping users/immigrants - it helps in word of mouth, growth - We use the same forms for Free and Plus. So, more feedback = more improvements.
Note: It's still in developement. But, the early feedback has been positive.
It runs completely on the user's computer so there is no service to maintain.
It is a new kind of data management system that was originally an object store to replace conventional file systems; but the tagging features I designed made it useful for creating, querying, and analyzing relational tables.
It is a hobby, so I like seeing how much faster I can perform operations than regular RDBMSs. It is extremely flexible, so lately I have been testing it out using large data sets. Creating tables with 100,000 columns or doing a pivot table in a 227M row table is fun for me.
See my profile for links.
Suddenly, a few of them have some friend requests, and then it grows. Until I see the numbers that could change the way I work, it's just a help for like-minded people, who like using sthing that goes beyond "this is vibecoded MVP". At the same time I really like going beyond that MVP bar, which is kinda de facto standard rn. So it's just a hobby of creating something cool
Though costs are low for me — few subscriptions (Supabase, GH) and $50 on LLM calls
Btw, why are you asking?
Because we use it (and depend on it), I am vested in making sure it works and continues to work well, and doesn't get too complex or complicated, unnecessarily.
That being said, I've made some money from donations, grants, and people paying me to manage instances for them, for example.
Cost is the VPS instance, which I already had, and apple developer fee per year. I need the clipper for myself, and put it out there without any monetization strategy and many folks are using it now. Have thoughts about adding some features for monetization if users ask for more. So far, it is doing the job for me and haven't heard any burning asks from others, so plan to keep it as is.
To keep costs down, I manage my own VPS and limit myself to projects that can run 100% client-side (e.g. no reliance on third-party APIs).
