vs Firefox Relay

Mozilla's alias service. Broadly the same idea, with a free tier and a paid one.

What it does well

Mozilla is a known quantity with a real privacy history, the browser integration is good, and the free tier lets people try the concept without paying anything.

Where it stops

The free tier is small. A handful of masks, which is enough to understand the idea and not enough to use it as a habit. Aliases only work if you make one every time, and a low cap trains you not to.

Custom domains are a paid feature with constraints, rather than the centre of the product.

It is a feature of a browser company, not a product on its own. That is not a criticism of the team, it is an observation about priorities. Mozilla has discontinued things before, and a service holding addresses you have handed out is one where "will this still exist in five years" is a fair question to ask of anyone, us included.

Mozilla's own data practices are a live conversation, particularly around their advertising work. Reasonable people disagree about how much that matters for Relay specifically. It is a conversation their users are having and it is worth knowing about.

What we do differently

No cap that discourages the habit. Custom domains and catch-all as the main event. Anonymous signup with no email address. Cash and crypto payment. Fully open source, including the server, so a self-hosted instance is a real option rather than a slogan.

What they do better

Mozilla's name carries weight ours does not yet, and the free tier costs nothing. If you want an alias service from an organisation with a twenty-year track record, that is a legitimate reason to pick them.

Last checked: August 2026. Tiers and limits change; check theirs.
