Best Zendesk Alternatives in 2026: Free, Open-Source and Hosted Help Desks

The best Zendesk alternatives depend on one question: do you want to host the software yourself? Zammad suits teams that want a full open-source ticket system, Help Scout suits small teams that want a hosted shared inbox, and Chatwoot suits teams that need live chat and social channels next to email.

Enlisted compares nine alternatives below, with Zendesk in the table as a baseline. The list starts with open-source tools you can run on your own server and moves on to hosted products. A decision guide follows, then a section on free help desk software for teams working with no budget.

Why people look for Zendesk alternatives

Zendesk is a customer service platform with ticketing, AI agents, reporting and a marketplace of apps. The reasons teams leave it tend to be practical:

• No free plan. Enlisted's pricing data lists a free trial but no free tier, so a small team or a side project pays from day one.
• Per-agent pricing. Every published plan is charged per agent per month, and the entry Support plan sits well below the Suite plans, so costs climb as you add seats or need more features. The top tier is quoted by sales. The current figures are on Zendesk's pricing page.
• Closed source and hosted only. There is no self-hosted version and no way to inspect the code, which matters if your customer conversations have to stay on your own servers.
• A large platform for a small job. AI agents, analytics and a marketplace are useful at scale, but a team that mainly needs email tickets and a shared inbox may use only a fraction of it.

How we picked

Each tool here does the core help desk job: it turns customer messages into tickets or shared conversations that a team can assign and answer. For open-source tools, Enlisted checks the licence, whether the repository is actively maintained and whether it can be self-hosted. For hosted products it records the published pricing model and whether a free plan exists. See how Enlisted ranks tools for the full method, or browse every customer support tool in the directory.

1. Zammad: best open-source Zendesk alternative for a full ticket system

Zammad is an open-source helpdesk that gathers email, chat, phone and social media requests into a single ticket system. Zendesk is a hosted product you rent. Zammad is software you can run yourself under the AGPL-3.0 licence, with the source code owned by the independent Zammad Foundation rather than by a vendor.

The company behind much of the development, Zammad GmbH, also sells hosting and support, so teams that do not want to run servers still have a route. It is a browser-based tool aimed at customer support, internal IT help desks and shared team inboxes, which makes it a broad open-source match for Zendesk's core job.

• Best for: teams that want a complete, multichannel ticket system and the option to move between self-hosting and vendor hosting.
• Watch out for: if you self-host, hosting, upgrades, backups and email delivery are your responsibility.

2. Chatwoot: best for live chat and social channels next to email

Chatwoot is an open-source customer support platform that puts website live chat, email, SMS and messaging channels in one shared inbox. Zendesk's pitch centers on ticketing and AI agents, while Chatwoot starts from a shared conversation inbox, with channels such as Facebook, Instagram, Twitter, WhatsApp, Telegram and Line listed in its own description.

It also includes a built-in help center portal for publishing articles and FAQs, an AI agent called Captain for automated replies, private notes with @mentions, canned responses and auto-assignment. You can self-host it or use the hosted cloud, which has a free plan for a very small team. Chatwoot appears again in the Intercom alternatives guide, since it targets both products.

• Best for: support teams whose customers write in through chat, WhatsApp or social media as often as through email.
• Watch out for: Enlisted lists its licence as "Other", so read the licence file in the repository if licensing terms matter to you. AI usage on the hosted plans is billed separately from the seat price.

3. FreeScout: best lightweight self-hosted shared mailbox

FreeScout is a free, self-hosted help desk and shared mailbox built on PHP and Laravel. Its README presents it as an alternative to Zendesk and Help Scout, developed from scratch without using copyrighted material from either product.

It handles tickets, shared mailboxes and an omnichannel approach to customer conversations, keeps data on your own server, and has mobile apps for agents. The project sells some optional add-on modules, so the core stays free but not every extra is.

• Best for: small support teams and agencies that live in email and are comfortable running a PHP application.
• Watch out for: some optional add-on modules are paid, so check that the features you need are in the free core before committing.

The official site is freescout.net, and the Enlisted entry is at /tools/freescout.

4. Frappe Helpdesk: best for SLAs and ERPNext users

Frappe Helpdesk is an open-source ticketing system from the Frappe team, built after they found the support module in ERPNext too limited. It gives agents and customers separate portal views, with customizable SLAs, assignment rules that route tickets by priority, issue type or workload, saved replies and a knowledge base.

It is released under the AGPL-3.0 licence, and self-hosting is free. Enlisted's pricing data shows managed hosting on Frappe Cloud priced by site and server rather than per agent, which is the opposite of Zendesk's model and can suit a growing team.

• Best for: teams that want SLA tracking and rule-based routing without per-agent fees, and companies already using ERPNext.
• Watch out for: the back end runs on the Frappe Framework with a Vue interface, so customizing it means working in that stack.

5. Libredesk: best single-binary help desk for email, chat and WhatsApp

Libredesk is a self-hosted support desk shipped as one Go binary, combining email, a website live chat widget and WhatsApp conversations in a shared inbox. It positions itself as a lightweight alternative to Zendesk, Intercom and Chatwoot, and is licensed under AGPL-3.0.

The feature list covers tags, custom statuses, snoozing, automations, macros, auto-assignment by agent capacity, SLA tracking and CSAT ratings. Role-based permissions, OIDC single sign-on, an API and webhooks are included, along with a help center and an AI assistant. WhatsApp connects through the Meta Cloud API.

• Best for: small teams that want a modern, easy-to-deploy self-hosted desk covering the main channels.
• Watch out for: Enlisted lists no vendor-hosted version, so you run it yourself.

6. Help Scout: best hosted shared inbox for small and mid-size teams

Help Scout is a hosted customer support platform built around a shared inbox, with AI assistance and automation for small and mid-size support teams. Compared with Zendesk, it keeps the product narrower: an inbox, a Copilot assistant for agents, an AI agent that automates workflows, a mobile app and Signal, which turns customer patterns into insights.

There is a free plan for a small number of users, which Help Scout's pricing page confirms, and paid plans are charged per user. The AI Answers add-on is billed per resolution rather than as part of the seat price. Its site speaks directly to teams ready to leave Gmail for a proper shared inbox, which is a useful hint at who it is built for. If Help Scout is the product you are leaving, the same self-hosted tools above also work as Help Scout alternatives.

• Best for: small teams moving from a Gmail inbox to a proper support tool, with no servers to run.
• Watch out for: closed source with no self-hosted version, and per-user pricing that grows with the team.

7. Freshdesk: best like-for-like hosted replacement

Freshdesk is a Freshworks help desk that brings support requests from several channels into one workspace, with workflow automation and a set of AI features. The vendor lists email AI agents that act on customer intent, an AI Copilot that helps agents prioritize, and AI Insights on service performance.

Its structure is close to Zendesk's: agent-based plans, a ticket-centered workspace and tiers that add features. Freshdesk's pricing page shows no free plan, only a free trial, so it does not solve the budget problem on its own. AI add-ons cost extra, and the current plans are on Freshdesk's pricing page.

• Best for: teams that want a hosted, familiar per-agent help desk and are leaving Zendesk for feature or contract reasons rather than to cut cost.
• Watch out for: no free plan, and AI features are sold as add-ons.

8. Zoho Desk: best for teams already on Zoho

Zoho Desk is Zoho's help desk, turning customer requests into tickets that agents can assign, track and resolve, with service level agreements and automation to keep response consistent as volume grows. It is part of the wider Zoho suite, so it connects naturally to Zoho's other business apps.

A free edition covers a small team, and paid editions add capacity and features. Enlisted's entry for this product is brief, so confirm channels, integrations and edition limits on Zoho's site before you commit.

• Best for: small support teams, especially those already using other Zoho products.
• Watch out for: the free edition is limited to a very small team, so growth moves you to a paid edition.

9. Jira Service Management: best for IT and internal service desks

Jira Service Management is Atlassian's service desk and IT service management product, built around request queues and SLAs for IT, operations and business support teams. Requests arrive through a portal or email, land in queues that agents work through, and can be escalated to engineers as Jira issues.

It also covers incident and change management and includes a knowledge base. There is a free tier for a small number of agents. Teams searching for Freshservice alternatives will find the same fit here, since both are service desks for employee and IT requests rather than customer-support inboxes.

• Best for: IT, operations and engineering-adjacent teams, especially those that already run Jira.
• Watch out for: its focus is IT and internal service requests, so a pure customer support team may prefer a tool built around customer conversations.

More Zendesk alternatives worth a look

The ten tools above cover most needs. These are also in the Enlisted catalogue and fit narrower cases.

Open source and self-hosted

• osTicket: a lightweight ticket system under the GPL-2.0 licence that collects requests from email, phone and web forms into one multi-user interface.
• UVdesk: a Symfony-based helpdesk under OSL-3.0 that converts email into tickets, with workflow automation and a support center portal. Hosted plans are available.
• Request Tracker: a Perl-based ticket and issue tracker under GPL-2.0 from Best Practical, with commercial hosting if you do not want to run it.
• Znuny: a GPL-3.0 continuation of the OTRS Community Edition, aimed at help desks and IT service management.
• GLPI: a GPL-3.0 IT service desk that combines ITIL-style ticketing with asset inventory and a configuration database. Along with Znuny, it is a self-hosted option for anyone searching for Freshservice alternatives.

Hosted

• Intercom: a customer service platform built around a helpdesk, inbox and its Fin AI agent. The Intercom alternatives guide covers the field from that side.
• Front: a shared inbox for email, live chat and text messages, where teams assign and discuss conversations together.
• Hiver: a shared inbox and helpdesk that runs inside Gmail.
• Gorgias: a help desk made for Shopify and other online stores that brings order information into the conversation.
• HappyFox: a help desk with ticketing, automation and a knowledge base for customer service, IT, HR and operations teams.

Which Zendesk alternative should you choose?

Two questions settle most decisions. First, can you host it? If yes, the open-source options remove licence costs and keep data in-house. If no, pick a hosted tool and use the free plan to test the fit. Second, which channels do customers actually use? Email-first teams are well served by FreeScout or Help Scout, while teams that rely on chat and messaging apps should start with Chatwoot or Libredesk.

Is there free help desk software?

Yes, in two forms. Open-source help desks are free to download and run on a server you control. A smaller group of hosted help desks offer a free plan that limits agents or features. Neither is free in the sense of costing nothing to operate.

Free and self-hosted. Zammad, FreeScout, Libredesk, Frappe Helpdesk, osTicket and UVdesk all have free open-source editions. Your costs move from licences to time and infrastructure: a server, a database, backups, upgrades, and a way to send and receive email. If nobody on the team wants that job, a vendor-hosted option from the same project, such as Zammad GmbH's hosting or Frappe Cloud, is the middle path.

Free hosted plans. Help Scout, Zoho Desk and Jira Service Management have free tiers aimed at very small teams, and Chatwoot offers a free cloud plan as well. Faveo Helpdesk lists a free Freelancer edition for a couple of agents alongside its open-source community edition. Each limits seats, features or both, so read the current limits on the vendor's pricing page.

What "free" usually leaves out. Expect caps on the number of agents, fewer automations and reports, and AI features billed separately. For a one-person support desk, a free plan is often enough. For a growing team, compare the paid tiers early so the switch does not catch you out.
