anon.li vs Firefox Relay

anon.li combines private email aliases, encrypted file sharing, and confidential forms in one account. Aliases forward messages to verified inboxes, allow replies without revealing a real address, and remove known tracking pixels and tracking parameters from forwarded HTML email. Drop encrypts files in the browser with AES-256-GCM and supports transfers up to 250GB; recipients can decrypt them in a browser without an account. Form supports confidential intake such as whistleblowing, patient intake, and legal contact. Each form uses its own P-256 keypair, and submitters' browsers encrypt answers with AES-256-GCM. The service has a REST API, CLI, MCP server, and browser extensions for Firefox and Chrome. Optional TOTP two-factor authentication includes backup codes. The maker says alias mail is forwarded rather than stored in a hosted mailbox, while Drop and Form content is stored as ciphertext. The free plan includes 10 aliases, one custom alias, one recipient, 5GB bandwidth, a 5GB maximum file size, three-day file expiry, three forms, and 50 submissions per month. Paid plans start at $2.49/mo; no free trial is offered.
