The Haystack delivers the essential tools your company needs to build long range, low power wireless-enabled products using DASH7. By combining HDO (Haystack’s open source and developer-ready DASH7 stack), with the powerful developer tools contained in H-Builder, and robust Haystack support, companies get access to the most complete and reliable internet of things development platform in the marketplace today.

Open source software projects enable rapid innovation, but also create challenges for long-term support as individual components and API’s evolve.  To address this gap, we include access to long-term maintained, stabilized, and comprehensively tested and hardened releases of The Haystack, including OpenTag, Haystack Server-side Applications, reference designs, and future components in development for The Haystack.  These supported commercial releases, available exclusively to Haystack customers, include certified binaries as well as source code.

With The Haystack, your company can build against defined, commercially maintained releases of OpenTag with the assurance of long-term binary compatibility and supportability, and without sacrificing the flexibility of open source.  That means your development team can build once and hand off to operations, without the need to constantly update your application to track the latest changes in open source community projects.
