Bitcoin software provider Breez has released a new app it says will serve both everyday users and developers. 

The product, dubbed Glow, is supposed to be an easy way to make Lightning transactions easier for everyday users, while also doubling as an open-source blueprint — a way to see exactly how easy it is to implement Bitcoin features using the SDK’s API — for builders. 

Breez claims the app will help developers exploring Bitcoin see what’s possible by packaging in the features that are essential for any Bitcoin app to compete in its category.

Being open-source, developers can open up Glow’s codebase and see exactly how each of those features — such as passkey login, Lightning addresses or stablecoin transfers — work and use them for their own app, rather than building it from scratch. 

For example, a developer building a social app doesn’t need to figure out how Lightning address or contacts should work — they can look at Glow’s code, see the API calls it makes, and replicate that in their own product with minimal effort. 

Developers can fork Glow, rebrand it, and ship it as their own, according to Breez. 

Because developers building on the SDK never take custody of user funds, Breez notes the regulatory footprint stays minimal — letting teams focus on product rather than compliance overhead.

The Glow app release comes after Breez announced it was working with Turnkey last month, a deal letting developers add non-custodial Bitcoin to apps running wallets from their own servers — solving a custody problem that has kept many of the largest consumer platforms from integrating Bitcoin at all.

According to the companies, keys now stay out of reach of the app’s servers, Breez, and Turnkey. The company’s backend holds a credential that defines what actions it can take, while authority to move funds rests with the user.

The deal positions some of the world’s largest consumer apps to add non-custodial Bitcoin without rebuilding their backend architecture or taking custody of user funds.
