Tidio vs Zendesk, paying per conversation or per agent
Tidio is a live chat inbox with a free plan for up to 10 people. It bills for the conversations your team answers and sells its AI agent, Lyro, in monthly packages. Zendesk is a helpdesk that charges for every agent and puts an AI agent on every plan, billed by the resolution past an allowance. Here’s what each costs, how each counts and caps its AI, and which kind of team each one suits. The third column is Deacon, an AI customer support agent for founders who answer support themselves. It has a free plan, and it needs no card.

What Tidio and Zendesk charge for
Tidio bills for the conversations your team answers
A billable conversation is one someone on your team replies in, counted once however long it runs. Messages nobody answers don’t count, and nor do replies from Lyro. Free covers 50 a month, Starter 100 and Growth from 250 to 2,000, and every self-serve plan has room for 10 seats at no charge. Lyro has a meter of its own. It counts every conversation it replies in, and it’s sold in monthly packages from 50 conversations to 1,000.
Zendesk bills for agents, then for resolutions
Every agent needs a paid seat, and chat on your site starts on Suite Team. AI agents come with every plan and are billed by the automated resolution, a request settled with no person stepping in. An allowance is included, which the pricing page counts in resolutions and the help centre in dollars. Past it, each resolution is $2.00, or $1.50 if you commit in advance, and the AI agent keeps answering unless you switch overage off.
The figures in these cards are from tidio.com/pricing, zendesk.com/pricing and Zendesk’s help centre, read on 23 September 2026. Zendesk AI pricing works through a month of Zendesk’s AI for one or two agents.
So the two bills grow with different things. Say three of you share the chat on your site. On Tidio, once you answer more than the free plan’s 50 conversations a month, that’s Starter, at $29 a month or $24.17 billed yearly, whether one of you replies or all three, because seats are free. On Zendesk, it’s three seats on Suite Team, at $69 an agent a month or $55 billed yearly, which comes to $207 a month, or $165 billed yearly, by our arithmetic, before the AI settles anything.
Tidio’s bill moves with volume instead. Starter covers 100 conversations a month between the three of you, and Growth starts at $59 a month for 250. Lyro comes on top, from $39 a month for 50 conversations. Zendesk doesn’t price by the conversation at all. It prices by the agent, and its AI agent answers on an allowance first, then at $2.00 a resolution, unless you set it to pause.

Its answers are what the plan sells |
| What the AI is counted by | Any conversation Lyro replies in at least once, solved or not. A conversation Lyro hands over straight away isn’t taken from the quota | A request the AI agent settled without passing it to a person.

| Bills that rise on their own | On a new project billed monthly below Plus, a package moves up a level at 95% of its quota unless you switch that off | Overage is on unless you switch it off, and it’s billed monthly whatever your subscription terms | Never.

| Removing their branding | Not on Free or Starter. A $20 a month add-on on Growth, or $16.67 a month billed yearly, and included on Plus | From the messaging widget, only on Suite Enterprise, which is sold through sales | No plan shows a “powered by” line, so there’s no badge to pay to remove |
| Handing over to a person | By default Lyro passes the chat to your inbox. During your hours it offers Talk to a person, and it can create a ticket instead | The AI agent escalates to your agents, and a request a person had to finish isn’t billed as a resolution | It says when it doesn’t know and asks for the visitor’s email. You’re emailed when they leave it or ask for a person, and your reply appears in their chat while it’s open |
| Seeing what customers ask | Basic analytics on every plan and advanced analytics from Growth. AI insights are listed with Premium, which is priced through sales | Prebuilt dashboards on every plan. Intelligent triage, which classifies every ticket by what the customer needs, starts on Suite Professional | Every conversation, searchable by what visitors asked, and Topics that group questions, count who asked and label most of them, on every plan |
| What the AI learns from | Website pages, up to 60 on a priority scan, Q&A pairs, CSV or PDF files, articles imported from a Zendesk help centre, and Shopify or WooCommerce products | Your Zendesk help centre, plus outside content brought in by a web crawler or a knowledge connector | A crawl of your website or single pages, files (PDF, Word, Markdown, text, CSV or HTML), pasted text and the answers you write |

Lyro Actions can check an order’s status or change an address, with one Action free | AI agents on every plan can connect to outside systems to read and write data and trigger actions | None. It answers questions, and it declines any about the visitor’s own account, order or data |
| Working with a helpdesk | A Zendesk integration on every plan, Free included, turns a chat into a Zendesk ticket with the customer’s details and messages. Its plan table lists Lyro Connect, which puts Lyro inside another helpdesk, on Plus and Premium | It’s the helpdesk, with more than 1,800 apps in its marketplace | It isn’t one and connects to none. You reply from Deacon’s own dashboard |
| For startups | No startup offer on its pricing page | Zendesk for Startups, the Suite free for 6 months, or up to 2 years through some funding partners | The free plan, with every feature on it |

Choosing between Tidio and Zendesk
Pick Tidio if a few of you answer customers in one inbox and you’d like to start free. Live chat, ticketing, email, WhatsApp, Facebook Messenger and Instagram are all on the free plan, for up to 10 teammates. It suits an online shop too. There are plugins for Shopify, WordPress, Wix and other platforms, Lyro can learn your products from Shopify or WooCommerce, and from Growth your team can cancel a Shopify order, change its address or offer a refund without leaving the chat.
Pick Zendesk if support is a team with queues, service levels and a phone line. Suite Team brings messaging, live chat, social channels and voice into one place, and Suite Professional adds phone menus, callbacks, skills-based routing and community forums. You decide before a busy month whether the AI agent keeps answering past its allowance or hands the work to your agents. And if you qualify, Zendesk for Startups can make the first 6 months free.
Or run both. Tidio’s Zendesk integration works on every plan, Free included, and turns a chat into a Zendesk ticket with the customer’s details and messages. Lyro can import your Zendesk help centre, and Tidio says it can answer inside Zendesk too, through Lyro Connect, which its plan table lists on Plus and Premium. Then Tidio bills the AI, per Lyro conversation, and Zendesk bills your agents.
Either way, you’re buying tools for a team. If you answer support yourself, between building, a seat price or a shared inbox is the wrong shape of bill, and there’s a third option.
Deacon, for founders who answer support themselves
A helpdesk and a live chat inbox both assume someone is sitting in them. When that someone is you, the same questions keep pulling you away from the product. Deacon answers them on your site in seconds, day or night, from your own docs and in the language each customer writes in, with no flows or macros to set up first. When your docs don’t cover a question, it tells the visitor it doesn’t know rather than inventing an answer, and asks for their email. You’re emailed when they leave one or ask for a person, and your reply from Deacon’s dashboard lands in their chat if it’s still open. That’s human handoff without a queue to staff.
Each gap turns into an answer once. The questions your docs missed are listed with an Answer this button, and what you write becomes part of what Deacon knows. Save & check then asks Deacon the question again, shows you the reply it gives now and counts how many other open questions your answer covers. The more you answer, the less it needs you.
You also see what your customers need, not only what the loudest few send you. Every conversation is saved and searchable by what visitors asked. Topics group the questions, count the people behind each one and label most of them, as a bug report, a feature ask, a how-to and so on, so you know what to fix and what to build. That’s on every plan, the free one included, where Tidio lists AI insights with Premium and Zendesk’s intelligent triage starts on Suite Professional. The same script counts your visitors, where they came from and which goals they reach.
And what you pay never waits on a model’s verdict about whether a conversation was resolved, because Deacon counts its own replies. Every feature is on every plan, and the plans differ only in answers, knowledge, crawled pages and seats, with the seats included. Nothing is billed past a plan’s answers, no plan moves itself up, and there’s no badge to pay to remove. The free plan gives you 50 answers every month, needs no card and has no end date.
