RangeViewr - FREE Preflop Tool for the Poker Community

RangeViewr - FREE Preflop Tool for the Poker Community

Built this initially for my own study, mainly because I couldn’t find what I wanted on the market. Then I thought I could turn this into something useful for the Poker Community:https://rangeviewr.com/
Feel free to test it and give feedback — I’m planning to maintain and improve it in my free time based on what people actually need, and hopefully make it a solid preflop tool for everyone.

Here are the main features I couldn’t find in one place: library sharing, range comparison, instant display, and cloud access.

➡️ Share range libraries instantly with friends :


You can share any custom library through a single link so your friends get it instantly.

➡️ Compare two ranges in a snap :


Makes comparing spots way easier afterwards.

➡️ Fast visualization (no clicking through spots) :


➡️ Cloud access to keep everything synced across devices : You just build everything through range tabs, pretty straightforward.


So I put this together — it’s free and supports building libraries from HRC / GTOW / PIO outputs.

If you’re doing preflop work with a group, I hope this tool save you a fair amount of time and avoid duplicated work.
Everything is customizable, and there’s a small onboarding to help you get started.

Since this is for the community first, feedback is more than welcome — here or on Discord: https://discord.gg/Dk7c8vyPaG
