Visit osTicket →"Free" means two different things in helpdesk software, and both are legitimate. Free SaaS tiers give you a hosted product at zero cost with limits on agents, channels, or features — perfect for a team that wants no infrastructure. Free self-hosted tools cost nothing to license but require a server and your time. We picked the strongest options in each camp, ruling out "free trials" masquerading as free plans.
If you have no ops capacity, a hosted free tier (Freshdesk, HubSpot, Zoho Desk, Spiceworks) is the obvious start — nothing to install, instant value. If you have a server and want unlimited agents with no feature caps, self-hosted (FreeScout, osTicket) wins once your team grows past the free-tier seat limits.
All six are free at the entry point. The catch differs: SaaS free tiers cap agents, automation, or channels and nudge you toward paid plans as you grow; self-hosted tools are free to license but cost a VPS (~$10–40/mo) plus your maintenance time. Map your real agent count and feature needs against each tier's limits before committing.
Free tiers trade away advanced automation, AI deflection, deep reporting, and SLA management — and SaaS free plans often limit channels or add branding. Self-hosted free tools trade away polish and hands-off operations. Free is the right starting point for a small team or a budget-constrained launch; expect to upgrade (or add ops work) as volume and complexity grow.
Don't over-engineer the choice — free means you can just try it. Stand up two candidates with a test mailbox, route a week of real tickets through each, and watch where your team is fastest. If a free tier's limits start to pinch within a month, that's a healthy signal you've outgrown free and should price the paid tier or commit to self-hosting properly.
