Free help desk software
Free help desk software comes in three shapes: a capped free tier (Freshdesk, Zoho Desk, AcornReply), a free ad-supported tool (Spiceworks), or free-to-license software you host yourself (osTicket, FreeScout), where the hosting is the price. Which suits you depends on whether your real constraint is seats, volume, or time.
Free help desk software is real, and every version of it is paid for by somebody. Working out how is the whole job of this page, because the plan you sign up for on Monday is the paywall you meet in three months.
Our own free plan is on the list with its limits printed rather than linked. AcornReply is free forever, not a trial, and that free plan gives you 20 AI drafts in total (a lifetime allowance, not a monthly one) plus 500 outbound emails a month. If the AI is the reason you are here, the first of those two numbers is the one that decides whether the plan fits.
Is free help desk software actually free?
Yes, in three different ways, and the difference decides which one suits you. A free tier is a paid product with limits, usually on agents, volume, or features, offered because the vendor expects you to grow into a paid plan: Freshdesk, Zoho Desk and AcornReply all work this way. Ad-supported free means the software costs nothing because your attention is the product, which is how Spiceworks has funded a free IT desk for years. Free and self-hosted means the license costs nothing while the server, upgrades, backups and security patching are yours, as with osTicket and FreeScout, and that is time rather than money, which for a small team is often the more expensive currency. None of these is a trial that expires, but every one of them has a ceiling somewhere, so the useful question is never whether a tool is free. It is which paywall you would reach first.
The free options, and what each one costs you
Same two questions for every row: where is the limit, and who is paying for the software?
| Tool | Best for | Pricing model |
|---|---|---|
Freshdesk A genuine free tier with a capped number of agents. Automations, reporting and the AI features begin at the paid tiers. | A small team that wants real ticketing at no cost | Free tier, then per agent, tiered |
Zoho Desk Email ticketing and a knowledge base for a handful of agents. The free tier is email only, so chat and social mean paying. | A few agents, especially alongside other Zoho tools | Free tier, then per agent, tiered |
Spiceworks Free because it shows ads to IT professionals. Bundles device inventory, which is why internal IT keeps choosing it. | Internal IT teams that want a free hosted desk today | Free, ad-supported |
osTicket No license fee at all. You pay in hosting, upgrades, backups and patching, which is a real cost with an unglamorous name. | Teams with a server and somebody to run it | Free self-hosted, plus a paid cloud edition |
Tawk.to Genuinely free live chat, funded by extras such as removing the branding. Chat only, so it complements a desk rather than replacing one. | A free chat channel on a site with no support budget | Free, with paid add-ons |
AcornReply Not a trial, and the draft allowance is lifetime rather than monthly. Paid plans are flat $20 a month for the whole workspace, not per seat. | A small team trying AI drafts on its own support email | Free forever: 20 AI drafts total, 500 outbound emails a month |
Every free tier is a funnel, including ours
Nobody gives away support software for the love of it. Freshdesk and Zoho Desk want you on a paid tier as soon as you add agents. Spiceworks wants your attention. The self-hosted projects want your contributions, or your money for a hosted edition. And we want you to keep drafting once your 20 free drafts are gone. None of that is a reason to avoid free tools. It is a reason to work out which ceiling you personally would hit first: watch the agent cap if you are about to add people, watch the volume cap if a small team sends a lot of mail, and watch the draft allowance if AI writing is the point. Then pick the tool whose limit sits furthest from where you actually live.
Frequently asked questions
What is the catch with free help desk software?
There is always one, and it is usually printed somewhere. Free tiers cap agents, volume or features and expect an upgrade. Ad-supported tools sell your attention. Self-hosted tools are free to license and cost you a server, upgrades, backups and security patching. The catch worth hunting for is the unprinted one: before you migrate, check that you can export your conversations, and check whether the free plan is permanent or a trial dressed as one.
Is there a free Zendesk alternative?
For a small team, yes, though not a like-for-like one. Freshdesk and Zoho Desk have free tiers covering ticketing basics that Zendesk charges for, Spiceworks is free for internal IT, and osTicket or FreeScout are free to license if you host them. AcornReply is free to start if what you mostly need is support email answered rather than a full desk. None of them reproduces Zendesk at scale: omnichannel routing, SLA dashboards and deep reporting are what you give up.
What is AcornReply's free plan?
Free forever, not a trial. It includes 20 AI drafts in total, which is a lifetime allowance rather than a monthly one, and 500 outbound emails per month. The inbox, the shared workspace and the help center are not draft-limited, so a team can keep answering email after the 20th draft. It is the AI drafting that stops until you upgrade. Paid plans are flat $20 a month for the whole workspace rather than per seat.
Is free help desk software good enough for a small business?
Often, for a while. A free tier comfortably covers two or three people answering a modest volume, and the limits that eventually bite are predictable: another person to add, a busier month, or one feature sitting behind the paywall. Plan the exit rather than the entry. Check the price of the tier above free, and check that your data comes out cleanly, because the cost of switching later is nearly always larger than the gap between two subscriptions.
