NEW (2026-09): If you are interested in a browser-based alternative to STAN, give OpenSEFA a try. OpenSEFA is an active research prototype, developed by MATPLUS in cooperation with TU Wien and Marcelo Forets. Links to a free hosted instance, the user manual, and the documention of the developed reconciliation engine (available on GitHub), together with further information, can be found in this Whitepaper. Feel free to test OpenSEFA, share your experience and contribute to its further development.
NEW (2025-08): STAN (designed for Windows) now also runs on Mac and Linux.
In October 2021, STAN was celebrating its 15th birthday! For this occasion, as a gift to our users, we created a series of video tutorials covering every aspect of STAN!

STAN was developed at the Research Unit for Waste and Resource Management at TU Wien under the direction of Helmut Rechberger. The mastermind behind STAN is Oliver Cencic, who created the mathematical, methodological and practical foundations for the design of STAN. The actual programming work was done by Alfred Kovac (inka software).
