Starred Tools

These are my top picks. Tools I've tested thoroughly and found to be excellent. They do their job really well, and I use them a lot. If you're not already familiar with them, I highly recommend checking them out.

Tested Tools

These are tools I've tried and found to be solid, but not standout. Think of them as passing an initial quality screen: worth exploring, though not all will be exceptional.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
