ScheduleSorter vs Bullet Solutions
The closest thing to a like-for-like competitor — aimed at a different buyer.
ScheduleSorter
Constraint solver
You enter events, instructors, rooms, attendees and the rules that constrain them. A constraint solver then searches for a weekly schedule in which nothing clashes — and when no such schedule exists, it names the specific enrolment and the specific rule that made it impossible.
From $24/mo, 14-day free trial, no card required
Bullet Solutions
Constraint solver
A genuine constraint-based timetabler for higher education, with mandatory, important and preferential priority levels, what-if scenario planning and room/resource optimisation. Part of Volaris, within Constellation Software.

Where Bullet Solutions is the better choice
This is the one product on the list solving the same technical problem ScheduleSorter solves. If you are a university with a timetabling office, Bullet Timetabler is a serious, credible choice and its institutional backing is worth real money to you.
- ✓A longer track record in large, complex institutional timetabling.
- ✓Explicit three-tier constraint priorities, more granular than a hard/soft split.
- ✓What-if scenario comparison built into the product.
- ✓The reassurance of Constellation Software behind the contract.
Where ScheduleSorter is the better choice
ScheduleSorter is a constraint solver: you describe the rules and it searches for a week in which none of them are broken. Instructors, rooms and attendees are each guaranteed to be in only one place at a time, because those are hard constraints in the model rather than warnings on a grid.
- ✓Published pricing and a free trial: you can test a real schedule against your own data today rather than booking a demo.
- ✓Built for programmes, studios, cohorts and rosters — not only degree timetabling.
- ✓Per-enrolment infeasibility explanations aimed at an administrator, not a timetabling specialist.
- ✓Set-up measured in an afternoon rather than an implementation project.
