Gravatar resolves an avatar from an email hash. It shows whatever image that person uploaded to their own Gravatar account. It is free, ubiquitous in developer tools and comment systems, and great when your users are the people whose photos you want.
Avtrz resolves the real business profile photo for a contact you do not control: a CRM contact, a prospect, a lead an agent surfaced. It works whether or not that person has ever heard of Avtrz.
How they compare.
When to use which.
Use Gravatar when the faces you need belong to your own users and they are likely to have set one up. Use Avtrz when you need the photo of a business contact you did not onboard, which is most of a CRM, a prospecting tool, or an agent's output. Plenty of teams use both: Gravatar for their account holders, Avtrz for everyone else.
Common questions.
Can I use both?
Yes, and many teams do. Gravatar for signed-up users, Avtrz for external business contacts, and a generated image as the final fallback.
Does Avtrz need an email hash?
No. Avtrz takes a plain email or handle as a query parameter and resolves the photo server-side.
Is Avtrz free?
There is a free tier, then usage-based pricing. Gravatar is free, but it is limited to people who set one up.
Real faces, where it counts.
