What it builds
Breez builds software that lets an application add bitcoin payments without running a Lightning node inside each user's device. Its current SDK documentation describes a nodeless integration that connects Lightning, Spark and on-chain Bitcoin. It provides bindings for mobile, web and server applications, and supports Lightning invoices, Lightning addresses and bitcoin addresses.
The code is published under the MIT licence in the Breez Spark SDK repository. Release 0.28.0, published on 5 November 2026, added a bridging client and support for silent payment addresses. That release record establishes maintained software. It does not prove that every binding, service provider or application integration has the same operating limits.
Custody and dependencies
Breez describes the SDK as non-custodial. Users can bring an external signer or use the included signer, and the documentation says they can withdraw to the Bitcoin blockchain without the Spark operators. The SDK still depends on more than local code. An integration needs a Breez API key, and features can rely on Spark operators, Lightning routing, chain services, swap providers and the application's own key handling.
Those boundaries matter. A unilateral exit is a recovery path, not proof that every payment uses Bitcoin's base layer directly. Developers also need to assess the operator model, fees, availability and recovery process for the exact SDK version they ship.
Organization and limits
Breez's official 2024 payments report says the company was founded in 2018. Current promotion terms identify the organizer as Breez Development LTD, which supports the limited-company classification. The opened sources do not establish a jurisdiction, so none is recorded.
No person profile is needed to describe the released software or the operating company, and no role is inferred from repository activity. No logo file is added because an attributed mark with stated reuse terms was not established. The site uses its existing monogram fallback.
