// Why we made this
Every tool on the web wants to sell you something — a plan, an add-on, an email, your attention. We didn't want to do that. So we made twenty-eight of the small, specific utilities we actually use, gave them away, and started honestly reviewing the SaaS you might pay for instead.
If you find us useful, tell a friend. If you find us beautiful, that's the part we worked hardest on.
