Free Help Desk Software, Honestly
Some free help desk software is a real product. Some of it is a trial wearing a costume. And open source is free the way a puppy is free.
The genuinely free help desk software
| Option | Free for | The catch |
|---|---|---|
| Freshdesk Free | Up to 2 agents, core ticketing | No SLAs, no automation depth |
| HubSpot Service Hub Free | Up to 2 users, basic tickets | No knowledge base or portal |
| Zoho Desk Free | A small number of agents | Limited channels and customisation |
| osTicket | Unlimited, self-hosted | You run the server, the upgrades and the backups |
| FreeScout | Unlimited, self-hosted | Same, plus modules for the useful extras |
| Zammad | Unlimited, self-hosted | Capable, and a real administration commitment |
When free is the right answer
Free genuinely works in two situations.
Free stops working the moment you need SLAs, custom roles, automation depth or a third agent. Those are the three walls, and every team hits one of them.
The real cost of self-hosting
Open source software is free. Running it's not.
Budget for a server, backups you have actually tested, TLS certificates, upgrades, email deliverability tuning, and somebody who owns all of that. A rough rule: if the equivalent SaaS costs less than a day of your engineer time per month, SaaS wins on cost alone before you count the risk.
The exception is scale. At a hundred agents the per-seat maths changes completely, which is why large support operations sometimes self-host.
The cost free plans don't remove
Duplicate tickets don't care what you pay for your helpdesk. A tenth of the queue is the same request arriving more than once on a free plan exactly as on an enterprise one.
On a free plan the cost lands entirely in agent time rather than licence fees, which for a two-person team is the more expensive currency. Run the numbers on the duplicate ticket cost calculator.
Frequently asked questions
What's the difference between a free ticketing system and free help desk software?
None. Free ticketing software, free helpdesk software and free customer service software all describe the same free tiers, and a free help desk ticketing system is what you get from Freshdesk, HubSpot or an open source install.
What is the best free help desk software?
Freshdesk Free for most small teams, HubSpot Service Hub Free if you already use HubSpot, osTicket or FreeScout if you must self-host.
Is open source help desk software really free?
The licence is. Hosting, upgrades, backups and email deliverability are not, and they usually cost more than a small SaaS plan.
When should we start paying?
When you need SLAs, custom roles or a third agent. Those three walls arrive in that order for most teams.
Free plan, same duplicate rate
On a free plan the duplicates cost you agent time instead of licence fees, which is the more expensive currency.
