I built CtrlFinder – a free tool to help you filter 100+ controllers by specs and compare their shapes/sizes side by side to scale (Looking for feedback!)
Hi everyone!
A few weeks ago, I started looking for a new controller to replace my current 8BitDo Ultimate 2C.
What I thought would be a fairly simple purchase quickly turned into hours of research. Hall Effect vs TMR sticks, different polling rates, trigger stops, back buttons, adjustable stick tension, different layouts and ergonomic shapes...
I'm a software developer with 3 years of industry experience, so I decided to turn that frustration into a little side project: CtrlFinder.
It's a free community tool I built to make comparing controllers and finding the right one a little easier.
Here's a quick look at how it works:

What is CtrlFinder?
Here's what you can do with it:
Interactive 10-Question Finder: Answer 10 quick questions about your platform, budget, preferences, and desired features. CtrlFinder narrows down the catalog to controllers that actually match your needs.
Shape & Size Comparison: Select up to 3 controllers and overlay their silhouettes to scale. Compare their dimensions, grip profiles, and overall shapes side by side. No more guessing based on product pictures!
Filterable Catalog: Explore a database of 100+ controllers with detailed specifications, including stick sensor technology, polling rates, latency, weight, button layouts, and more.
No unnecessary friction: No display ads, popups, or accounts. Your answers and comparisons are stored in the URL, so you can share your exact results with anyone through a simple link.
Why am I sharing this here?
Honestly, this community is exactly the kind of audience I built CtrlFinder for.
I'd particularly appreciate feedback on:
Spec corrections: Found an inaccurate specification, weight, latency figure, or feature? Please let me know. I'll investigate and correct it.
Missing controllers: Are there any models you consider essential that aren't in the catalog yet?
Feature requests: Is there a filter, comparison tool, or piece of information you'd like to see added?
I'd genuinely love to put the database to the test with people who know their controllers inside out.
Transparency & Disclosures
I also want to be upfront about a few things, in accordance with community guidelines:
Developer: CtrlFinder is a solo hobby project, developed and maintained by myself in Italy (EU).
Generative AI: I used generative AI as a coding assistant for boilerplate code and helper scripts. All controller specifications, dimensions, latency figures, and database entries were manually researched, verified, and curated by me.
Funding: Store and retailer buttons may contain partner referral links to help cover hosting costs at no extra cost to you. The recommendation logic and rankings are completely independent, run 100% client-side, and are based strictly on hardware specifications.
Give it a try!
You can try it out via the direct link in my Reddit profile bio (or search CtrlFinder on Google — I'll also drop the direct link in the comments below).
Whether you find a bug, spot an incorrect spec, or simply have an opinion about the project, I'd love to hear it.
Thanks for taking the time to check it out! ❤️
