About

A self-hosted alternative to Gravatar.

Your own avatar endpoint: GET /avatar/<name> returns a deterministic geometric blobatar SVG for any username, email or id, with Gravatar-compatible URLs.

Features

  • Get the same avatar every time for the same username, email or ID
  • Embed avatars in your website with an image URL
  • Choose the avatar size, colors, background and expression
  • Reuse Gravatar-style URLs by changing the host
  • Keep the original avatar style with a generation setting

Deploy blobatar API on Cloudflare

  1. Step 1: Set up Appflare in your Cloudflare account

    Once

    Appflare installs itself into your own Cloudflare account from your browser, and runs on the free Workers plan, as blobatar API does. See what blobatar API needs on your account.

    Set up AppflareAlready have Appflare? Install blobatar API

  2. Step 2: Install blobatar API

    blobatar API needs no keys or settings from you.

    One switch on the form puts blobatar API behind Cloudflare Access, so only the people who use your Appflare can open it.

  3. Step 3: Finish setting it up

    After the install, Appflare shows a short step for blobatar API, on its page.

With Appflare instead of by hand

  • Nothing to build on your computerAppflare sets itself up from your browser, with no API token to create and nothing to install.
  • Updates in one clickAppflare tells you when the catalog has a new version, and Update installs it.
  • Health checksAfter every install and update, Appflare checks that the app answers.
  • It stays in your own accountEverything runs on your Cloudflare account and your plan, and Appflare records what it creates, so an uninstall removes it.

What it needs on your account

Nothing beyond a Cloudflare account on the free Workers plan.
