LNbits, free and open-source Lightning wallet and accounts system.

LNbits — The most powerful Bitcoin & Lightning toolkit

Run it for yourself, for your community, or as part of a larger stack.

What is LNbits?

LNbits is a lightweight Python server that sits on top of your Lightning funding source. It gives you safe, isolated wallets, a clean API, and an extension system for rapidly adding features - without locking you into a single node implementation. The Inspiration for LNBits came from ideas pioneered by OpenNode and LNPay — both today work as funding sources for LNbits.

What you can do with LNbits

• Harden app security: Create per-wallet API keys so individual apps never touch your full balance.
• Extend functionality fast: Install extensions to explore and ship Lightning features with minimal code.
• Build into your stack: Use the LNbits HTTP API to integrate payments, wallets, and accounting.
• Cover LNURL flows: Use LNbits as a reliable fallback wallet for LNURL.
• Demo in minutes: Spin up instant wallets for workshops, proofs-of-concept, and user testing.

Funding sources

LNbits runs on top of most Lightning backends. Choose the one you already operate - or swap later without changing your app architecture.
