The Verdict
osTicket is built for small businesses and budget conscious teams, with a focus on ticket-management and email-piping. Polar targets open source developers and indie hackers and leads with subscriptions and one-time-payments.
Polar uses custom enterprise pricing, while osTicket starts at $12/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Polar has a slight overall edge — but if completely free self-hosted version matters most to you, osTicket may still be the right call.
