Highlights

Pros

  • 0% added transaction fees — no extra markups on top of standard Lightning Network routing fees, unlike many competing wallets.
  • Nostr Wallet Connect (NWC) protocol enables granular permission-based app connections with defined spending budgets and expiry limits.
  • Fully open-source and self-custodial — users retain complete control of their private keys and funds at all times.
  • Comprehensive developer toolkit including SDKs, WebLN, Bitcoin Connect, NWC CLI, and AI dev sandbox for embedding zero-custody bitcoin payments.
  • Custom Lightning and Nostr address with sub-wallet support — create unlimited sub-wallets for family, friends, or teams under one node.

Cons

  • Bolt 12 support and planned ecash integrations (Cashu, Fedi) remain on the roadmap but are not yet implemented.
  • Self-hosting Alby Hub requires technical knowledge of Lightning node management and channel liquidity, which can be daunting for non-technical users.
  • Alby Go mobile app is designed primarily for NWC/app connectivity rather than traditional human-to-human wallet interactions.
  • Account registration was temporarily restricted to invite-only during peak demand, signaling scaling challenges with a 10-person team.
  • Lightning Network limitations apply — users must keep their node online to receive payments and manually manage channel liquidity.
