Made me think of <https://github.com/LeonHeidelbach/trailblazer.nvim>, one of my favorite neovim plugins. Can highly recommend it as a harpoon and marks alternative!

Show HN guidelines state that their should be an easy way to use your product.

How can I test your product without giving you my email address and/or paying USD150? Is there a free tier?

Good point, I read over that in the guidelines, I removed the Show HN from the title accordingly. My apologies its my first HN post, we offer free trials for users on case by case basis - send an email to lodi@labofdata.com with what you plan on using the product for and we'll follow up with you about free trial details.
