A customer messaging platform is the software that collects your customer conversations from live chat, email, SMS and messaging apps into one inbox, routes them to the right person and, on most platforms now, lets an AI agent answer the routine ones. The nine platforms below cover that job for a website that needs to capture leads and answer customers in real time: Intercom, Zendesk, HubSpot, Freshchat, Crisp, Front, respond.io, Tidio and Gorgias.
Vendor prices and channels on this page come from each vendor's own pricing or product pages. Prices change often, so confirm on the vendor's site before you sign.
One disclosure before the list: we make CoSupport AI Agent, an AI agent for customer support. It isn't a messaging platform, so it isn't in the list. It gets its own short section at the end, next to a table of what AI agents cost on each platform.
The order below is editorial, large suites first and specialists after. It isn't a ranking.

1. Intercom: best for an AI-first support suite
Best for: teams that want the helpdesk, the live chat and the AI agent from one vendor.
Channels: Messenger live chat, email, phone, WhatsApp, Instagram and Facebook, SMS, Discord and Slack.
Price: Essential is $29 per seat per month billed yearly, with $19 shown for new customers. Advanced is $85 and Expert is $132 per seat. Pay annually to save up to 35%.
Free plan or trial: 14-day free trial, no credit card. The pricing page lists no free plan.
AI agent: Fin costs $0.99 per outcome on every plan. An outcome counts when the customer confirms the issue is resolved, doesn't ask for more help, or Fin completes a workflow, including a handoff. Intercom reports a 76% average resolution rate across its Fin customers.
One thing to check: the seat price is the floor. WhatsApp is charged per message sent and SMS per message on top, and the Copilot add-on for agents is $29 per teammate per month billed yearly. If you use Fin with another helpdesk, a minimum commitment applies.
2. Zendesk: best for support at scale across many channels
Best for: larger support teams that need ticketing, voice and messaging in one system.
Channels: messaging and live chat, email, voice, text messages (an add-on), Facebook, Instagram, X, WhatsApp, Slack, WeChat and LINE.
Price: Support Team is $19 per agent per month billed yearly, but that plan is email and tickets. Messaging and live chat start at Suite Team, $55 per agent per month. Suite Professional is $115.
Free plan or trial: 14-day trial of Suite Professional. The pricing page lists no free plan.
AI agent: $1.50 per automated resolution on a commitment, $2.00 pay-as-you-go. Suite plans include 5 to 10 automated resolutions per agent per month before the meter starts. A resolution means the AI agent closed the conversation without escalating it.
One thing to check: the $19 headline price doesn't include live chat. For a website chat widget, budget from $55 per agent. Our comparison of Zendesk, Freshdesk and Intercom on AI automation goes deeper on the three suites.
3. HubSpot: best for website leads with a CRM behind them
Best for: sales and support teams that want chat conversations logged in the same CRM as their contacts.
Channels: live chat, email, forms and meeting booking. HubSpot's customer agent also answers on WhatsApp and Facebook Messenger, and there is a voice option.
Price: a free tier with no credit card. Starter is per seat; the page shows only a limited-time promo price, so check the current figure. Professional is $90 and Enterprise $175 per seat per month billed yearly, with 10,000 and 15,000 HubSpot Credits a month included.
Free plan or trial: free plan.
AI agent: the customer agent is $0.50 per resolution and runs on HubSpot Credits. A resolution means the agent helped and the conversation wasn't handed to a person for 72 hours. A qualified lead can also count as a resolution, so sales chats can bill at the same $0.50. It needs a Professional or Enterprise edition.
One thing to check: live chat and meeting booking are on the free plan, but automated follow-up and the AI customer agent start at Professional. Chat routing rules can send a chat to the least busy of the selected teammates, which needs a Sales or Service seat.
4. Freshchat: best for a low per-agent price with a free tier
Best for: teams that want messaging channels at a low per-agent price.
Channels: chat widget and email on the free plan; Facebook, Instagram, SMS, WhatsApp and LINE from Growth.
Price: Free for up to 10 agents. Growth is $19 per agent per month billed yearly, Pro $49, Enterprise $79.
Free plan or trial: free plan; 14-day trial of Enterprise.
AI agent: Freddy AI Agent is $49 per 100 sessions, which is $0.49 per session, after the first 500 sessions included.
One thing to check: social and text channels start at Growth, so the free plan is website chat and email only.
5. Crisp: best for a flat price per workspace
Best for: small teams that don't want to count seats.
Channels: chat widget on Free; WhatsApp Business, Instagram DMs, SMS, LINE and Viber from Essentials.
Price: Free for 2 agents. Mini is $45, Essentials $95 and Plus $295 per month per workspace, with 4, 10 and 20+ seats included and $10 per month for each extra agent.
Free plan or trial: free plan; 14-day trial, no card.
AI agent: AI runs on credits included in each plan ($5, $25 and $75 worth). The pricing page shows included credits and rough conversation estimates, not a per-outcome price.
One thing to check: WhatsApp, Instagram and SMS start at Essentials ($95). If those channels are the reason you're shopping, that's the real starting price.
6. Front: best for a B2B shared inbox
Best for: account-based support where several people work the same email threads.
Channels: Starter is one channel type. Professional and above add email, SMS, social and WhatsApp.
Price: Starter is $25 per seat per month billed yearly for up to 10 seats. Professional is $65 and Enterprise $105.
Free plan or trial: 14-day trial of Professional, no card. The pricing page lists no free plan.
AI agent: Autopilot starts at $0.05 per conversation. That unit is a conversation, a lower bar than a resolution, so it isn't comparable one to one with the resolution prices above.
One thing to check: the WhatsApp channel is an add-on billed with Meta's message costs plus a 20% admin fee.
7. respond.io: best for WhatsApp-first messaging
Best for: businesses whose customers write on WhatsApp, Instagram and other messaging apps first, and websites second.
Channels: WhatsApp, Instagram, Messenger, TikTok, Telegram, Viber, LINE, WeChat, plus calls and email.
Price: Starter is $79 per month billed yearly, Growth $159, Advanced $279. From Growth up, the price also depends on monthly active contacts.
Free plan or trial: 7-day trial, no card. The pricing page lists no free plan.
AI agent: AI Agents start on the Growth plan with included AI credits. The pricing page lists no unit price.
One thing to check: WhatsApp message fees are billed by Meta on top of the subscription. respond.io's AI Agents qualify leads, book appointments and pass chats to the right agent with the full history.
8. Tidio: best for small teams and ecommerce
Best for: small stores and teams that want chat, Flows (Tidio's automation builder) and an AI agent at a low entry price.
Channels: live chat, email, WhatsApp, Messenger and Instagram.
Price: Starter is $24.17 per month on the annual toggle and covers 100 billable conversations. Growth starts at $49.17, Plus at $300 plus usage.
Free plan or trial: free plan; 7-day trial, no card.
AI agent: Lyro is sold as a quota of AI conversations. The smallest stand-alone quota is $32.50 per month for 50 conversations on annual billing.
One thing to check: "billable conversations" is the unit on the Starter plan. Count your monthly chats before you pick a tier.
9. Gorgias: best for Shopify stores
Best for: ecommerce support teams that live in Shopify. Gorgias describes itself as built for ecommerce and Shopify.
Channels: email, live chat, social and a contact form, plus TikTok Shop. SMS and voice are add-ons. The vendor also names WhatsApp, Instagram and Facebook.
Price: helpdesk-only plans: Starter is $10 per month for 50 tickets on monthly billing. Basic is $50, Pro $300 and Advanced $750 per month on annual billing ($60, $360 and $900 billed monthly). The pricing page also shows bundles that include the AI Agent.
Free plan or trial: 7-day trial. The pricing page lists no free plan.
AI agent: $0.90 per automated interaction on annual billing, $1.00 on monthly, with $1.50 overage. Each AI interaction also counts as a ticket against your plan.
One thing to check: Gorgias prices by ticket, with no per-agent fee. If your volume is seasonal, the plan you need in November isn't the plan you need in February.
Which platform fits which job
Most searches for a customer messaging platform start with one job. Here's which platforms cover each job and the plan to check, according to the vendors' own pricing and product pages.
| The job | Platforms that do it | Plan to check |

Before The Conversation Starts - ZoomInfo
ZoomInfo: know who's on your site before the conversation starts. Customer messaging platforms help you engage website visitors, but engagement without identification is an opportunity lost. ZoomInfo sits upstream of the conversation, identifying anonymous visitors in real time, enriching records with firmographic and contact data, and automatically routing high-intent accounts to your sales team.
Tools like WebSights de-anonymize your website traffic so you know which companies are browsing and what they're viewing. FormComplete shortens web forms by auto-populating verified contact fields, reducing friction and increasing conversions. And when a high-value account lands on your pricing page, ZoomInfo's intent signals trigger your chat and outreach tools at exactly the right moment.
For sales teams serious about prospecting with precision, pairing your messaging stack with ZoomInfo's intelligence layer is how you close the gap between traffic and revenue.
When Leads Start in Instagram DMs - InstantDM
Website chat isn't the only way businesses can capture and qualify leads. Brands also generate valuable leads through Instagram comments, Story replies, and direct messages. InstantDM helps businesses automate these interactions through comment-to-DM automation, keyword-triggered messages, and Story reply automation. It allows brands to automatically deliver links, share resources, collect leads, and follow up with interested users without manually handling every conversation. For businesses that rely on Instagram for marketing and lead generation, InstantDM complements website messaging platforms by automating conversations on social media.
How to choose
Start with the channel, then add the channel fees
Pick the platform that names the channels your customers actually use. Then read the fine print on fees: respond.io and Front say Meta bills WhatsApp message costs on top of the subscription, Intercom charges WhatsApp and SMS per message as usage, and Gorgias sells SMS and voice as add-ons. A $19 seat is only the start: WhatsApp and SMS add per-message fees, and Front adds a 20% admin fee on top of Meta's.
Know what the price is based on
Five pricing bases show up in this list, and the same team gets a very different bill on each:
- Per seat: Intercom, Zendesk, Freshchat, Front, HubSpot. Cheap for small teams, grows with every hire.
- Per workspace: Crisp. One price for the workspace, with a set number of seats included.
- Per ticket: Gorgias. Grows with ticket volume.
- Per monthly active contact: respond.io from the Growth plan. Grows with your customer base.
- Per billable conversation: Tidio's Starter plan.
A worked example from the published prices: a team of 5 agents handling 3,000 conversations a month pays about $95 per month on Zendesk Support Team ($19 × 5), $275 on Suite Team if they need live chat ($55 × 5), $145 on Intercom Essential ($29 × 5), $55 on Crisp Mini (4 seats included plus one extra at $10), or $95 on Essentials if they need WhatsApp, Instagram or SMS, and about $660 on Gorgias Pro ($300 plus 1,000 extra tickets at $0.36), if each conversation is one ticket. None of those figures include AI resolutions or channel fees, and on Gorgias each AI interaction also counts as a ticket.
Decide where the help desk ends and the messaging platform begins
A messaging platform is where conversations arrive and get answered. A help desk adds tickets, queues and reporting. Intercom, Zendesk and Gorgias sell both in one product. If you already have a help desk, you may only need the messaging layer, or only an AI agent on top of what you have.
Some teams choose the inbox first, such as Hiver, which pulls email, chat, Slack and voice into one queue, then add an AI agent on top.
Support teams whose conversations need to reach product and engineering can look at DevRev, which puts support, product and engineering on one system and links each ticket to the engineering issue behind it.
What an AI agent costs on each platform
All nine platforms sell an AI agent, and most bill it in a different unit. The table shows the published price and the unit each vendor bills.
| Vendor | AI agent price | What the vendor counts | Plan needed |
|---|---|---|---|
| Intercom (Fin) | $0.99 | Per outcome: customer confirms, asks for nothing more, or a workflow completes | All plans; minimum commitment with another helpdesk |
| Zendesk | $1.50 committed, $2.00 pay-as-you-go | Per automated resolution without escalation | Suite Team and up, after included allowances |
| HubSpot (customer agent) | $0.50 | Per resolution: no handoff for 72 hours; a qualified lead can also count | Professional or Enterprise, on credits |
| Freshchat (Freddy) | $0.49 ($49 per 100) | Per session, after the first 500 | Growth and up |
| Gorgias | $0.90 yearly, $1.00 monthly | Per automated interaction; also counts as a ticket | Every plan |
| Front (Autopilot) | From $0.05 | Per conversation | Add-on on every plan |
| Tidio (Lyro) | Quota pricing (from $32.50 for 50) | Per AI conversation | Stand-alone or with a plan |
| Crisp | Credits included in the plan | No unit price on the pricing page | Credits from Mini |
| respond.io | AI credits included in the plan | No unit price on the pricing page | Growth and up |
| CoSupport AI Agent | $0.50 | Per AI resolution: 72 hours without a customer reply; unresolved tickets free | Zendesk, Freshdesk, Intercom, Zoho Desk, or standalone |
Intercom and Gorgias include their AI agent on every plan and charge per outcome or interaction, and Tidio gives 50 free Lyro conversations. Zendesk (from Suite Team), HubSpot (from Professional), Freshchat (from Growth), Crisp (from Mini) and respond.io (from Growth) keep the AI agent for higher tiers, and Front sells Autopilot as an add-on on every plan.
Units differ: an outcome, a resolution, a session, an interaction and a conversation aren't the same thing, so these prices aren't like for like. For how per-resolution and flat-fee models compare on real volumes, see per-resolution vs flat-fee pricing for AI support.
Add an AI agent on top of your helpdesk
CoSupport AI Agent is the AI layer that answers routine tickets from your company's own knowledge and closes them. It runs inside Zendesk, Freshdesk, Intercom and Zoho Desk, going live in about 10 minutes on Zendesk, or as a standalone chat widget on your site when you don't have a helpdesk.
You pay $0.50 per AI resolution, and tickets the AI doesn't resolve cost nothing. The first 1,000 AI responses are free, so you see the resolution rate on your own tickets before you pay. HubSpot publishes the same per-resolution price, and Freshchat and Front publish lower units of a different kind, so this isn't the lowest AI line on the page. A resolution here means the customer hasn't replied for 72 hours after the AI's answer.
The agent answers in 120+ languages, replying in the customer's language. Chat that qualifies website leads is a different job from resolving tickets; our guide to AI chatbots for lead generation covers it.
