Before you choose

Requirements & limits

The project documents official distributions for Chromium-based browsers and Firefox desktop and mobile. It also provides separate nightly builds for development versions.

  • WebLN support is central to the website interaction model.
  • The extension supports LND, CLN and custodial options rather than a single documented backend.
  • It includes LNURL-pay, LNURL-auth and LNURL-withdraw support.
  • Its scope emphasizes web payment and authentication flows instead of full node and channel management.
  • A native companion can relay calls to native applications for connections such as nodes behind Tor.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
