3 Free & Open-Source Zendesk Alternatives
Zendesk prices per agent, so a support team of five or six adds up quickly even before you touch the higher automation tiers. A self-hosted helpdesk removes the per-seat cost entirely — you pay for a server, not for each person who logs in.
The best Zendesk alternatives
Chatwoot
Our top pickOpen sourceSelf-hostedAn open-source live-chat and helpdesk inbox in one.
Chatwoot combines a website live-chat widget with a shared team inbox that also pulls in email, WhatsApp, and other channels — closer to Zendesk's newer omnichannel positioning than a plain ticketing tool.
- Multi-channel shared inbox (chat, email, WhatsApp, and more)
- Canned responses and basic automation rules
- Team collision detection (see who's replying)
- Self-hosted or Chatwoot's own cloud plan
Zammad
Open sourceSelf-hostedA self-hosted ticketing system built for structured support workflows.
Zammad leans closer to classic Zendesk ticketing — queues, SLAs, escalation rules — making it a good fit for a support team that already thinks in tickets rather than live-chat conversations.
- Ticket queues with SLA and escalation tracking
- Email, chat, and social-channel integration
- Knowledge-base module for self-service articles
- Fully self-hosted
Tawk.to
FreeHostedA free, hosted live-chat widget — no self-hosting needed.
Tawk.to is the fastest tool on this list to set up: paste a script tag and you have a live-chat widget and shared inbox running, genuinely free with no seat limits. It's less feature-rich than Chatwoot, but there's nothing to host or maintain.
- Website live-chat widget, free with unlimited agents
- Basic ticketing and canned responses
- Mobile apps for replying on the go
- Hosted by Tawk.to — no server required
Licensing and pricing models change over time — confirm current terms on each project's own site before making a procurement or compliance decision.
Frequently asked questions
What's the easiest free Zendesk alternative to set up?
Tawk.to, by a wide margin — it's a hosted widget you can add to a website in minutes with no server to manage. Chatwoot and Zammad are more capable but both need to be self-hosted.
Can a self-hosted helpdesk handle email support as well as chat?
Yes — both Chatwoot and Zammad handle email tickets alongside chat, so you're not limited to live chat alone.
Is Chatwoot or Zammad better for a small team?
Chatwoot if live chat and multi-channel messaging (WhatsApp, Instagram) matter most to you. Zammad if your support runs primarily on structured email tickets with SLAs.
