Alby offers a set of Bitcoin Lightning wallets and tools for using bitcoin online via self-custodial wallets, applications, and cloud hosting services.
Alby is known mostly as a service that helps to send, receive and manage Bitcoin Lightning payments via Alby Hub and browser extension. It supports connections to applications that work with Lightning and Nostr protocols. It is aimed at users who want to make Lightning transactions.
The availability may change, but Alby is not a promo-code-based platform. Discounts can be achieved by selecting the right type of setup, such as free self-hosting or paid cloud hosting, depending on your preferences.
Pricing information can change, and Alby provides free and self-hosting options to people who want to control the settings themselves. This can be an excellent choice for people who want more control and don't want to pay for cloud hosting.
Self-hosting is usually better if you want more control, while Alby Cloud is more convenient since it involves the process of hosting itself, but it requires a monthly subscription fee.
In terms of savings, Alby usually doesn't charge transaction fees in some cases, but Lightning routing fees can still be applied. Always be aware of the difference between service fee and network fee before sending any transaction.
The easiest way to save money is to use either free self-hosted version or paid one if you want more convenience. If you prefer cloud hosting, you should calculate how much time and effort it saves compared to the monthly subscription fee.
It should be noted that Alby can be beginner-friendly if you want to use a guided option to use Lightning Network. If you are more technical, then self-hosting option will be preferable since it provides more control.
