This is the Web Submit map with third party tools to show cells. We are not allowed to share links to third party tools. We used to be allowed to share links to the Wayfarer Discussion Discord where we can discuss these tools, but Niantic started removing those links, too. If you are really interested, you should be able to search Google for wayfarer tools and find a link to the discord server.
The person who created these tools has spoken about them openly here. They are not designed to help cheat, but for understanding and accuracy. 2025 is near the end, what's your proudest Wayspot project? - #4 by Tntnnbltn
