Alby Wallet bridges the gap between Lightning Network payments and the web browser — a connection that no other wallet handles as seamlessly. Starting as a browser extension for one-click Lightning payments, Alby has evolved into Alby Hub: a self-custodial Lightning node that connects to web applications through Nostr Wallet Connect (NWC). If you use Nostr, tip content creators, or want to pay for web services with bitcoin, Alby is the wallet designed specifically for that workflow.
This review covers Alby Hub’s architecture, its NWC integration, deployment options, fee structure, and how it compares to mobile-first Lightning wallets in 2026.

From Extension to Hub: Alby’s Evolution
Alby started in 2022 as a browser extension that let users pay Lightning invoices on websites with a single click — similar to how a password manager auto-fills login forms, Alby auto-fills Lightning payments. The extension connected to external Lightning backends (your own node, LNbits, or Alby’s custodial wallet service).
In 2024-2025, Alby phased out its custodial shared wallet and launched Alby Hub — a self-custodial LDK-based Lightning node that users can run on their own hardware, on a cloud server, or via Alby’s managed cloud service. The browser extension still exists but now connects to your Alby Hub rather than to a third-party custodian.
This transition moved Alby from a custodial convenience layer to genuine self-custody — a significant philosophical and technical shift.
Nostr Wallet Connect (NWC): The Killer Feature
Alby’s most significant contribution to the Lightning ecosystem is Nostr Wallet Connect (NWC), an open protocol standardized as NIP-47. NWC lets any application request payments from your wallet through the Nostr protocol, without the app ever touching your funds.
Here is how it works in practice:
- You run Alby Hub (your Lightning node)
- You create an NWC connection for a specific app (e.g., a Nostr client like Damus)
- The app receives permission to request payments up to limits you define
- When you want to zap a post on Nostr, the app sends a payment request to your Alby Hub via NWC
- Your Alby Hub processes the payment from your self-custodial balance
The breakthrough: your wallet is always available for payments without keeping a mobile app running. NWC works across platforms — web apps can connect to your hub, mobile apps can connect to your hub, even other desktop applications. The one-click wallet connection flow makes linking a new app as simple as a QR code scan.
NWC has been adopted beyond Alby itself. Other wallets and services now implement the protocol, creating an open standard for wallet-app communication.
Deployment Options
Alby Cloud
The easiest option. Alby runs your node on their cloud infrastructure. You retain your keys, but Alby manages the server. This is self-custodial (Alby cannot spend your funds) but not fully sovereign — you depend on Alby’s infrastructure for availability. Alby Cloud costs a small monthly subscription fee.
Self-Hosted on Your Hardware
Run Alby Hub on a Raspberry Pi, home server, or any Linux machine. Full sovereignty — you control the hardware, the node, and the network connection. Requires basic Linux administration skills and a stable internet connection.
Self-Hosted on a VPS
Deploy Alby Hub on a cloud VPS (Digital Ocean, Hetzner, etc.). You control the software but rely on the VPS provider for hardware. A middle ground between convenience and sovereignty.
Alby Hub can also run on existing node platforms like Umbrel and Start9 as an application, integrating with your broader Bitcoin node setup.
Fee Structure
- Alby Hub software: Free and open source
- Alby Cloud hosting: Subscription fee for managed hosting (varies by plan)
- Lightning payments: Standard network routing fees only — no Alby markup on transactions
- Channel management: On-chain fees for opening/closing channels. LSP fees if using managed liquidity
- Browser extension: Free
The only paid component is Alby Cloud hosting, which is optional. Self-hosting eliminates all recurring costs.
The Browser Extension Experience
Alby’s browser extension remains its most visible product. Once installed and connected to your Alby Hub, it enables:
- One-click payments on any website that supports Lightning (LNURL, Lightning Address, or BOLT 11 invoices)
- Nostr zaps — tip posts directly from your feed with a single click
- Website authentication — log into services using Lightning (LNURL-auth)
- Budget controls — set daily or per-app spending limits so connected apps cannot drain your balance
The extension is available for Chrome, Firefox, Edge, and Brave. It integrates with the browser’s native payment API where supported.
Pros and Cons
Pros
- Best browser-native Lightning payment experience — nothing else comes close for web payments
- Nostr Wallet Connect (NWC) enables seamless app-wallet communication across platforms
- Multiple deployment options from fully managed to fully self-hosted
- Multiple Lightning backend support (LDK, LND, Phoenixd, Cashu)
- Budget controls and per-app permissions prevent overspending
- Open source
- Contributed NWC as an open standard benefiting the broader ecosystem
Cons
- No native mobile app — mobile access requires connecting a third-party NWC-compatible app
- Self-hosting requires technical skills (Linux, networking, port forwarding)
- Alby Cloud adds a monthly cost that other wallets do not have
- LDK-based node is less mature than LND or CLN for advanced routing scenarios
- Initial channel setup requires opening at least one channel (manually or via LSP)
- Primarily optimized for small to medium payments — not designed for large-value Lightning transactions

Verdict
Alby is not trying to be the best mobile Lightning wallet. It is the best Lightning wallet for the web. If your Lightning usage centers on Nostr interactions, tipping content creators, paying for web services, or building applications that integrate Lightning payments — Alby Hub with the browser extension provides a workflow that no mobile wallet can replicate.
The NWC protocol is Alby’s lasting contribution. By creating an open standard for wallet-app communication, Alby has made Lightning wallets composable — any app can request payments from any NWC-compatible wallet, creating a pluggable payment layer for the internet.
For daily mobile spending, Phoenix remains the better choice. For running your own node from a phone, Zeus excels. But for connecting Lightning to the web ecosystem — Alby is unmatched.
Frequently Asked Questions
Is Alby Wallet custodial or non-custodial?
Alby Hub is self-custodial — your keys are generated and stored locally (or on your self-hosted server). The former custodial shared wallet service has been discontinued. Alby Cloud manages the server infrastructure but does not have access to your private keys or funds.
Do I need a Nostr account to use Alby?
No. Alby Hub functions as a standard Lightning wallet without any Nostr involvement. However, the browser extension and NWC features are specifically designed to integrate with Nostr, so the best Alby experience includes Nostr usage.
Can I use Alby on my phone?
Not directly as a native app. However, you can connect NWC-compatible mobile apps (like certain Nostr clients) to your Alby Hub, giving you mobile access to your Lightning funds through those apps.
What happens if Alby the company shuts down?
If you self-host your Alby Hub, nothing changes — you run the software independently. If you use Alby Cloud, you would need to migrate your node to self-hosted infrastructure. Your seed phrase allows on-chain fund recovery in any scenario. The NWC protocol is an open standard and would continue to function independently of Alby the company.
