Stilo is software for the digital management of administrative acts (atti amministrativi) by Italian public bodies. According to the README it covers drafting, checks of accounting regularity, adoption, archiving and preparation for publication, and can record attendance and votes for collegial acts. It also offers workflows tied to a case file, ordinary and certified email (PEO and PEC), notifications, reports, digital signatures and timestamps. Stilo is installed as server software on your own infrastructure; the README lists Java SE 8, an Oracle database and JEE8.
The copyright (2023) is held by Regione Piemonte, the City of Turin and the Metropolitan City of Turin, so by Italian public authorities. The licence is AGPL-3.0-or-later with a linking exception for libraries. Because you run the software yourself, acts and case files stay within your own organisation; no hosted version from the maintainers is described. The project is listed in the Italian Developers Italia catalogue. The README also mentions CSI-Piemonte, but does not describe its exact role.
