Alby
Lightning wallet and browser extension — send and receive sats on the web, with a hosted or self-hosted hub.
Alby is a Lightning wallet and browser extension that brings sats to the web — sending and receiving payments, logging into Lightning-enabled sites, and streaming value while you browse. You can use its hosted hub to get started or connect your own node for full self-custody.
It is one of the smoothest on-ramps to actually using Lightning day to day, especially for tipping, paywalls and web-native payments. The hosted option is custodial for convenience; the open-source, connect-your-own-node path is there when you want to graduate to holding your own keys.
