How we make money
This directory is free to browse. We keep the lights on by:
- Display ads: third-party ad units (for example Google AdSense) on some pages. Ads are labeled and never styled like directory results.
- Optional email updates: if you share your email, we may email when we add, remove, or materially update sources in this directory. You can unsubscribe anytime. We do not sell your email to outside marketers.
No site pays us to be listed, and no site can pay for a better rating or a higher spot. Ads never change which sources we list or how we rate them. A listing is not an endorsement.
