FET
What it is
FET is free software for building timetables for schools, high schools, and universities. It supports automatic, semi-automatic, and manual allocation, with time and space constraints for teacher and student availability, preferred times and rooms, gaps, working hours, and room or building changes. FET imports CSV and accepts flexible XML input; completed timetables can be exported as HTML, XML, or CSV. The maker states algorithm limits of 500,000 activities, 30,000 student subgroups, 30,000 rooms, and 30,000 buildings. The software runs on Linux, macOS, and Windows under the GNU Affero General Public License version 3. Documentation includes manuals, instructions, tips, and frequently asked questions, alongside a user forum. The maker also lists tools for converting FET XML timetable results to Microsoft Excel and importing FET-compatible timetables into RosarioSIS. It says complicated schedules usually take 5–20 minutes, simpler ones under five minutes, and extremely difficult ones may take hours. The download page publishes SHA256 checksums for release files and an ASCII signature for the source archive.
