# Apple targets app bugs with SigLens acquisition Apple acquires SigLens to detect errors in complex app networks. - **Source:** [Cult of Mac](https://brifing.si/source/7e2968d9-bc24-4286-8f9e-146807f06336) - **Published:** 2026-07-13 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/b4ee033e-a89f-41c9-a550-84799f989189 ## Apple's new acquisition Apple has acquired SigScalr, the developer behind SigLens, a tool designed to detect bugs in apps composed of hundreds of interconnected small programs. The deal was disclosed under the EU's Digital Markets Act. ## Complexity of modern apps Today's apps often consist of multiple small processes communicating with each other, making error tracking difficult. SigLens aims to solve this by providing developers with a real-time monitoring dashboard for the entire ecosystem. ## Advantages of SigLens SigLens claims to be twice as efficient as competitors like Datadog and Splunk. For a company like Apple with a vast software empire, having an in-house tool that speeds up debugging could be a significant advantage. ## SigScalr's background SigScalr was a small startup based in New Hampshire that operated in stealth mode for three years. It open-sourced SigLens in 2024. The company had 2-10 employees and about $2 million in pre-seed funding. ## Apple's strategy Apple has been focusing on acquiring developer tools recently. Last month, it purchased Play, a SwiftUI prototyping app. SigLens similarly aims to make developers' lives easier, including Apple's own engineers. ## Expected Xcode integration SigLens technology is expected to be integrated into Xcode's developer toolkit. With the rise of AI-generated code, the need for such monitoring tools is increasing. ## Sources covering this story - https://www.cultofmac.com/news/apple-siglens-acquisition-debugging — --- _Summary written by Brifing from the original reporting.
