The right choice depends on whether your team needs ticketing, multichannel customer conversations, or a shared inbox—and on whether the exact apps you rely on support the actions your workflow requires. Zendesk has the largest vendor-reported catalog among the three products compared here; Intercom and Help Scout document smaller catalogs with different support and integration features. Catalog counts are not evidence of equivalent integration depth or quality.
Help desk software with marketplace integrations at a glance
| Product | Integration evidence | Support model and examples | Pricing information in the cited sources | Best fit |
|---|---|---|---|---|
| Zendesk | More than 1,200 marketplace apps, according to Zendesk’s undated Marketplace page accessed in 2026. | Official examples include Slack, Jira, Shopify, Salesforce, and Workday. Zendesk documents ticket actions in Slack and customer and order details from Shopify. | The cited sources do not establish a comparable current seat price. Zendesk says some integrations are free and paid listings state their costs. | Teams that need a broad app directory and want to connect support work with business, engineering, commerce, or HR systems. |
| Intercom | 450+ apps and integrations, according to Intercom’s page accessed in 2026. The catalog count is vendor-reported. | Its integrations page covers CRM, developer, ecommerce, and billing tools; documented support channels include email, live chat, phone, SMS, WhatsApp, and social media. | Intercom’s help desk page displayed $29 per seat per month plus $0.99 per outcome when accessed in 2026. This is a volatile vendor-published price, not a guaranteed quote. | Teams managing multichannel customer conversations that also need connections to CRM, engineering, commerce, or billing apps. |
| Help Scout | 100+ apps, according to its pricing and features page accessed in 2026. | Named connections include Salesforce, HubSpot, Aircall, Jira, and Linear. It also lists custom apps, API access, webhooks, and OAuth apps. | The cited pricing and features page does not establish a single integration price for all plans. Plan matrices can restrict features; the source does not give a comparable seat-price figure here. | Teams that want a shared support inbox and integrations with common business, calling, or developer tools. |
The catalog figures come from the vendors’ own pages and use counting methods that are not established as equivalent. They indicate published directory scale, not the number of apps that will meet a particular team’s needs.
How to choose a help desk for marketplace integrations
1. Define the workflow, not just the app name
Write down what agents need to do without leaving the help desk: view customer or order details, create or update a ticket, file an engineering issue, or handle a call alongside an email conversation. Then check the relevant app listing and documentation for those exact actions. A directory entry alone does not establish what data syncs, which side can make changes, or what permissions are required.
For example, Zendesk says its Slack integration can create, view, and act on support tickets, while its Shopify integration displays customer and order details to agents. Those are concrete workflow examples, not proof that every Slack or Shopify use case is covered.

Choose based on the work your team handles most. Intercom documents a support context spanning email, live chat, phone, SMS, WhatsApp, and social messaging. Help Scout’s examples focus on connections such as Salesforce, HubSpot, Aircall, Jira, and Linear. Zendesk’s documented examples range across collaboration, engineering, commerce, HR, and CRM systems. These examples show the kinds of connections each vendor discusses; they do not demonstrate equal channel or app coverage.
3. Check availability, administration, and plan requirements
Confirm whether an integration is publicly listed, private to your company, restricted to particular plans, or dependent on custom development. Zendesk distinguishes public Marketplace integrations from private integrations built for an individual company. Help Scout lists custom apps, API access, webhooks, and OAuth apps, but its plan matrices may restrict features. For any vendor, determine who will configure and maintain the connection and whether your team needs vendor or implementation-partner help.
4. Calculate the full cost for your workload
Compare seat charges with any outcome or usage fees, paid integrations, add-ons, implementation, and the staff time needed to administer the connections. Zendesk says some Marketplace integrations are free and some cost extra; its support documentation says paid listings state their costs and usually offer a free trial. Intercom’s displayed price combines a per-seat charge with an outcome charge, so the seat figure alone would not represent the full cost. Do not assume an integration is included just because it appears in a vendor’s directory.
1. Zendesk: best-supported choice when catalog breadth matters
Zendesk’s Marketplace advertises more than 1,200 apps on an undated page accessed in 2026. That is the largest published catalog figure among the three products in this comparison, but the count should not be treated as a measure of connector quality or depth.

What its integrations can do
Zendesk Support documentation names Workday, Slack, Jira, Shopify, and Salesforce among its integrations. Zendesk says its Slack connection can create, view, and act on support tickets; the Shopify connection displays customer and order details to agents. These examples are useful if support depends on collaboration, engineering escalation, ecommerce context, HR systems, or CRM data. Check the individual listing for the exact workflow you need.
Zendesk’s support documentation explains the distinction between public and private integrations: “Public integrations are available on the Zendesk Marketplace for anyone to use.” A private integration is developed for an individual company and is not listed for other customers. A team needing a bespoke connection should therefore account for development and administration, rather than assuming a Marketplace listing exists.
Costs and limitations
Zendesk says many integrations are available for free, while some have a cost. Paid listings state their costs, and Zendesk says they usually offer a free trial. The cited sources do not establish a comparable current Zendesk seat price or show that every integration is included with every plan. Check the listing’s price and prerequisites, as well as how the connection behaves in your workflow, before buying.
Zendesk is a strong candidate when several business systems must connect to support operations and its catalog contains the required apps. The vendor-reported app count alone cannot establish that a particular connector supports the data, permissions, or actions your team needs. See the Zendesk Marketplace and Zendesk’s guide to using the Marketplace.

2. Intercom: best-supported fit for multichannel customer conversations
Intercom’s integrations page states that it connects to 450+ apps and integrations; the page was accessed in 2026. It names Salesforce and HubSpot for CRM, Jira, Linear, and Asana for developer work, and Shopify and Stripe for ecommerce and billing. The same page describes support across email, live chat, phone, SMS, WhatsApp, and social media.
Integration and channel fit
Intercom’s documented combination of customer-contact channels and business-app connections can suit teams handling conversations across several channels while bringing CRM, engineering, commerce, or billing context into support work. The 450+ figure is Intercom’s own directory count. It is not directly comparable with Zendesk’s count because the two vendors’ catalog scope and counting methods are not established as equivalent, and it says nothing by itself about how deeply a specific app integrates.
Displayed price and limitations
Intercom’s help desk pricing page displayed $29 per seat per month plus $0.99 per outcome when accessed in 2026. The amount is vendor-published and may change or vary by package or use, so treat it as a dated reference rather than a quote. The cited information does not establish whether every named integration is available on every plan or whether any connector has a separate charge. Check the current Intercom integrations directory and Intercom’s 2026 help desk comparison for the vendor’s descriptions; that comparison is Intercom’s editorial assessment, not an independent test.
3. Help Scout: best-supported fit for a shared inbox and common business tools
Help Scout’s pricing and features page lists access to 100+ apps. Its named integrations include Salesforce, HubSpot, Aircall, Jira, and Linear, and it also lists custom apps, API access, webhooks, and OAuth apps.

Help Scout gives examples of creating a Jira issue from a conversation and managing Aircall calls and texts alongside email and chat. These workflows can be relevant to teams that want support conversations connected to developer issue tracking or calling tools. The company’s plan matrices can restrict features, so the presence of an integration in Help Scout’s materials does not establish that the needed functionality is included in every plan.
The cited page does not establish one price that applies to all integrations or a comparable current seat-price figure for this article. Check the current plan details and any add-on terms for the specific connection you intend to use. Help Scout’s pricing and features page is the source for its app count and integration examples.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What “best marketplace” can—and cannot—mean
A larger marketplace can make it more likely that a team will find a listed connection, but it does not show whether the connection supports the required sync direction, fields, permissions, reliability, or plan. Nor do the available vendor-published figures establish an objective winner for marketplace quality. Intercom’s 2026 list and the independent iTechGuides comparison with prices and plans checked August 16, 2026 are useful dated comparisons, but neither is a neutral controlled test of integration quality. Treat rankings as editorial assessments rather than measured outcomes.
For a real evaluation, compare the exact app listing and supported actions for each finalist, then test the workflow using representative users and data before rollout. Include any permission model, error handling, and ownership responsibilities in that check: an integration that can display context but cannot safely update the systems agents need may not solve the operational problem.
