Which Platforms and Services Use Gravatar?

Gravatar is used by WordPress, GitHub, Slack, OpenAI, Atlassian, Figma, Mailchimp, Stack Overflow, and Coinbase, among thousands of other platforms. If you use the same email address across these services, each one can pull your Gravatar avatar and profile automatically — so you upload and update your image in one place instead of on every site. This is worth setting up if you want a consistent identity across tools you already use, and less useful if you only care about a single platform.

Platforms That Display Gravatar

Gravatar's own site lists the following services as users of its avatars and profiles:

The key point is that these are not integrations you configure yourself. Gravatar works by matching the email address you registered with on each platform to the profile tied to that same address on Gravatar.

How the Matching Actually Works

Gravatar links your identity to an email address, not to your name. When a platform supports Gravatar, it takes the email address on your account, hashes it, and requests the corresponding image from Gravatar's servers.

The hashing is visible in Gravatar's own developer examples. In JavaScript:

const sha256 = require('js-sha256');

function getGravatarURL(email) {
  const address = String(email).trim().toLowerCase();
  const hash = sha256(address);
  return `https://gravatar.com/avatar/${hash}`;
}

In PHP:

function get_gravatar_url($email) {
  $address = strtolower(trim($email));
  $hash = hash('sha256', $address);
  return 'https://gravatar.com/avatar/' . $hash;
}

Two details matter for whether your avatar shows up:

• The email must match exactly. Both examples trim whitespace and lowercase the address before hashing, so casing and stray spaces are normalized — but a different address (work vs. personal) produces a different hash and therefore a different avatar.
• The platform must actually request the image. Being on the list above means the service supports Gravatar; it does not guarantee every surface within that product displays it.

What Syncs When You Update

Gravatar's stated behavior is "update once, sync everywhere." When you change your avatar or profile, the changes appear across the platforms that pull from Gravatar, rather than requiring a separate upload on each one. Your profile can also carry social links, a portfolio, a website, and other links, functioning like a digital business card or link-in-bio page.

Because Gravatar ties identity to an email address, you can manage separate work, personal, and anonymous profiles under different addresses.

Privacy Controls

Gravatar states that you control what is shared: you can make your profile private or choose what you share and when. If you are deciding whether to set one up, the practical question is which email address you use on the platforms above — that address is what determines which profile those services can surface.

When Gravatar Is Worth Setting Up

• Worth it if you use several of the listed platforms with the same email and want one avatar to follow you across them.
• Worth it if you want a single link-in-bio page tied to that identity.
• Less useful if you only use one platform, since you can set an avatar directly there.
• Check first if you use different email addresses per service — you would need a Gravatar profile for each address to get consistent results.
