Best Free Help Desk Software in 2026: 8 Tools Compared

Zoho Desk free edition is the closest thing this category has to a full hosted desk at no cost. Three agents get email ticketing, a customer portal, a private knowledge base, predefined service levels, and mobile apps, with no time limit. For a startup or a small support team, that covers the actual job of answering customers and tracking requests.

Paid plans start with Express at $7 per agent per month billed annually, then Standard at $14, which adds more automation and reporting. The free plan omits answer bots, telephony, and multi-department ticketing, and the interface packs in a lot, so expect a learning curve. Still, for email-led support on a zero budget, Zoho Desk is the benchmark.

HubSpot Service Hub free tools suit teams already using HubSpot CRM, or teams that want support and customer records in one place. Free ticketing, a shared inbox, live chat, and basic knowledge base tools let a small team answer customers without buying a separate desk. Customer history from the CRM appears alongside tickets, which helps avoid asking repeat questions.

The free tier is not a full enterprise desk. Reporting, automation, and advanced routing sit on paid plans, and seat details vary by HubSpot plan page, so check the current free tools page before you scale. If your business already lives in HubSpot, starting with its free service tools is simpler than adding a disconnected desk.

tawk.to is the best free option when support happens mainly in live chat. The free plan includes chat, ticketing, a knowledge base, and monitoring tools, with no published cap on agent seats. That makes it practical for larger chat teams that would blow past the three or five seat caps on other free plans.

The trade-off is polish. The dashboard packs many features into one place, and some users find it busy at first. Paid add-ons remove tawk.to branding and add AI features, but core chat and ticketing remain free. If your customers contact you from your website in real time, start with tawk.to.

Help Scout free plan covers up to five users with one inbox and a limited contact count, which suits micro teams that live in email. The inbox feels like email, not a complex ticket queue, so new agents learn it fast. Customers get plain, personal-looking replies, and the knowledge base helps deflect repeat questions.

Paid plans start higher than Zoho Desk, so Help Scout is less attractive once you outgrow free limits and need many seats. For a tiny team that values simplicity and a friendly customer experience over deep automation, the free plan is generous and easy to run.

Crisp combines live chat, email, and a shared inbox in a modern interface that small teams find easy to use. The free plan covers two seats and core messaging, which fits a founder plus one support person, or a tiny team testing chat support. A knowledge base and basic automation help answer common questions without a paid plan.

The free limits are real. The pricing page caps a free workspace at 100 customer profiles, with no sub-inboxes and no AI credits, so growing teams will need to upgrade. Crisp is a good free start for website chat, but check those caps against your customer volume before you commit.

Chatwoot is an open source customer engagement platform that you can self-host for free, or use as a hosted service on paid plans. It brings email, live chat, WhatsApp, and social messages into one inbox, with automation and reporting on top. Because you run it yourself, there is no licence seat cap, which suits teams with many agents and technical skills.

The cost is time, not licence fees. You need hosting, updates, backups, and security care, and support comes mainly from community and documentation on the free version. Chatwoot is our pick for technical teams that want full control and no per-seat bill, and who accept the maintenance work that comes with it.

osTicket is the classic open source ticket system, and it remains useful for internal IT desks and small teams that need straightforward email ticketing. Customers can submit tickets by email or web form, agents can assign and reply, and basic reporting tracks workload. There is no licence cost and no seat limit on your own server.

The interface feels dated next to modern desks, and it lacks built-in live chat and AI features without add-ons. Hosting, updates, and backups are your job. If you want a simple, stable, free ticket queue and you can run a web server, osTicket still does that job well.

Zammad is a more modern open source alternative to osTicket, with a cleaner interface and support for email, chat, phone, and social channels. Agents get a single workspace for tickets, and customers can use a web portal. Self-hosting means no licence fee and no seat cap, while paid enterprise options add support and extra features.

As with Chatwoot, the free version trades licence cost for maintenance work. You handle hosting, security, and upgrades. Zammad suits teams that want a current-looking desk, full data control, and no per-agent pricing, and that have someone able to run it.
