AT Protocol vs Let's Encrypt
Who’s behind each, what their homepages track, what they cost and how often their policies changed, measured the same way for both. By what they offer, they’re close.
Documentation and developer resources for the AT Protocol, an open standard for decentralized social networking that underpins Bluesky, covering user-owned domain identities, JSON data records with shared schemas, and a public event firehose.
A nonprofit certificate authority that issues free, automated TLS/SSL certificates so websites can enable HTTPS, using the ACME protocol and client software for issuance and renewal.
