Zendesk charges $19–$115 per agent per month on a yearly plan, and its AI is billed on top: AI agents per automated resolution, Copilot at $50 per agent. If that bill is why you are looking, the seven tools below all cost nothing to start. We compared what each free plan really includes, where AI costs extra, and when Zendesk is still the better choice.

Plans and prices as listed on each vendor's pricing page on October 17, 2026. Vendors change them often, so check the pricing page before you buy.
1. CustomerGPT
CustomerGPT is an AI agent that answers your customers from your own content: website pages, help-center articles and files. Instead of handing your team another inbox to work through, it answers the repeat questions itself and passes the rest to a person.
Best for: SaaS, e-commerce and service teams whose tickets are mostly questions the docs already answer, and who want those answered without paying per agent.
- Trains on what you already have: crawl your site from one URL, upload PDF, DOCX, TXT, MD or CSV files, or sync your Zendesk Help Center.
- Goes live with a single script tag, about two minutes after you paste your URL.
- Answers in 95+ languages.
- Hands the chat to your team when a visitor clicks Speak to a Human Agent; you reply from Chat History.
- Lists the questions it could not answer, so you know which article to write next.
From $49 / month, billed yearly
$59 month-to-month. Starter: 1 team member, 4,000 messages a month. Growth ($99): 4 team members, 10,000 messages. Scale ($349): 10 team members, 40,000 messages. AI on every plan, no per-agent or per-resolution fees.
Free: a 14-day full-access trial with no credit card, then a free tier with 1 chatbot, 100 pages of content and 100 AI messages a month (no API or integrations).
Watch out for: each plan has a monthly message limit. When it runs out, the bot stops answering until the count resets or you add 5,000 messages for $49/month. It is not a ticketing system either: there are no queues, SLAs or phone support.
Why Teams Choose CustomerGPT
“Cheaper than Zendesk” is a claim, so here is the arithmetic. Monthly prices on a yearly plan, from each pricing page on October 17, 2026:
| Team size | Zendesk Suite Team, seats only | CustomerGPT, AI included |
|---|---|---|
| 1 person | $55/mo | $49/mo (Starter, 4,000 messages) |
| 4 people | $220/mo | $99/mo (Growth, 10,000 messages) |
| 10 people | $550/mo | $349/mo (Scale, 40,000 messages) |
Suite Team is Zendesk's cheapest plan with live chat and messaging, and its column is seats only: AI agents are billed per automated resolution and Copilot adds $50 per agent per month, so the gap widens once AI is on. CustomerGPT's limit is message volume, not people.
Price follows volume, not headcount
A new teammate does not add a seat fee. Plans include 1, 4 or 10 team members.
AI is the product, not an add-on
Every plan answers with AI, including the free tier after the trial.
Setup is a URL, not a project
Crawl your site or sync Zendesk, paste one script tag, and test it the same day.
CustomerGPT vs Zendesk
Zendesk is a full help desk; CustomerGPT is an AI agent that sits in front of your support. Here is what changes when you switch, including what you lose.
| Feature | CustomerGPT | Zendesk |
|---|---|---|
| Pricing | Flat per plan, from $49/mo billed yearly | Per agent, $19–$115/mo billed yearly; live chat from $55 (Suite Team) |
| Free option | 14-day trial, then a free tier (1 chatbot, 100 AI messages/mo) | No free plan |
| AI answers for customers | Included on every plan | AI agents billed per automated resolution |
| Setup | About 2 minutes: crawl your site, paste one script tag | A configuration project: admin setup, workflows, team training |
| Knowledge sources | Website crawl, file uploads, Zendesk Help Center sync | Help Center articles |
| Human handoff | Speak to a Human Agent; your team replies from Chat History | Native ticketing with queues and SLAs |
| Department routing | Escalation webhook on Scale and Enterprise | Built-in multi-department routing |
| Phone support | Not available | Zendesk Talk |
What you give up
- Native ticketing with queues, SLAs and reporting
- Built-in multi-department routing
- Phone support through Zendesk Talk
- Handoff alerts: CustomerGPT does not send email or push notifications for handoffs yet
What you gain
- AI answers on every plan, with no per-resolution fee
- One flat price instead of a seat for every agent
- A working assistant built from content you already have
- Answers in 95+ languages
How to switch from Zendesk
- Export first. Download your tickets and Help Center articles before you cancel, because access ends with the subscription.
- Bring your Help Center over. In CustomerGPT, open Integrations → Knowledge Bases & Helpdesk Sync and connect Zendesk to sync Help Center articles and solved tickets (Growth plan and above). On any plan you can crawl your help-center URL instead.
- Make it yours. Set the bot's name, greeting and colour in the Customizer, then paste the embed script on your site.
- Run both for a week. Check the answers against your docs, then remove the Zendesk widget.

2. Tawk.to
Tawk.to is the only tool on this list that stays free however big the team gets. Live chat, ticketing and a knowledge base cost nothing; the company earns from paid extras instead.
Strengths
- Unlimited agents, chats and tickets on the free plan
- Knowledge base included
- Live in about 10 minutes
Weaknesses
- The “Powered by” branding stays unless you pay $29/month
- AI Assist answers from your knowledge base, but is free only for sites with limited chat volume, then from $29/month

Free plan. Branding removal and AI Assist from $29/month.

- Self-service help center included
- A cheap first paid step: Express from $7/agent/month, billed yearly

Free for 3 users. Paid plans from $7/agent/month, billed yearly.
When it is the better choice: Choose it over CustomerGPT if your support runs on email tickets, your team is three people or fewer, and you already use Zoho CRM.

From $0

Strengths
- Chat widget, shared inbox and contact form for 2 seats
- Mobile apps included
- Live in 10–20 minutes
Weaknesses

Strengths
- Up to 10 seats on the free plan
- Live chat and ticketing in one widget
- Set up in 15–30 minutes
Weaknesses
- 50 billable conversations a month is fewer than 2 a day

From $0
Free for 50 conversations a month. Paid plans from $29/month, Lyro AI extra.
When it is the better choice: Choose it over CustomerGPT if you get only a handful of chats a week and want them handled in a free widget. See CustomerGPT vs Tidio.
7. Freshdesk
Freshdesk is the closest like-for-like Zendesk replacement here, but it is not free for long: the pricing page offers $0 for 1–2 agents for the first six months, with no permanent free plan.
Strengths
- Full traditional ticketing, the nearest match to Zendesk
- Free for 1–2 agents for six months
- Paid plans from $19/agent/month, billed yearly
Weaknesses
- Every agent is billed once the six months end

- Full setup takes 1–3 days
From $0 for 6 months
Then from $19/agent/month, billed yearly.
When it is the better choice: Choose it over CustomerGPT if you need a complete ticketing system and are ready to pay per agent once the free months run out. See CustomerGPT vs Freshdesk.
Which Tool Is Right for You?
Every free plan caps something: seats, conversations, contacts or AI. Pick the tool whose limit you will hit last.
Choose CustomerGPT if most of your tickets are questions your docs already answer and you want them answered automatically, without a seat fee for every person on the team. If your team lives in tickets, queues and phone calls, keep a help desk and put CustomerGPT in front of it.
