There is no evidence-based universal winner for Zendesk teams in the available product information. The clearest choice depends on whether you want Zendesk’s native AI agents, a custom build with Sunshine Conversations, or a third-party bot. Zendesk’s September 2026 guidance also makes migration timing part of the decision: legacy bot-builder features are scheduled for removal in December 2026.
This is a decision guide, not a ranked test. The available sources establish these three approaches and identify Ada as a vendor-described integration, but do not support ranking seven independent chatbot products or comparing their real-world performance. Before choosing, compare the channels you need, what the agent is allowed to do, how it hands work to people, usage charges, and the effort to move any legacy bots.
Which chatbot approach fits a Zendesk team?
Zendesk documents three routes: use its native AI agents, build a customizable experience with Web Messenger and Sunshine Conversations, or connect a third-party bot through the Zendesk or Sunshine Conversations marketplace. These are different implementation paths, not equivalent products with independently measured results. Zendesk says the features and setup of marketplace bots depend on their developers. Zendesk’s overview of chatbot options explains the routes.
| Option | Best fit | What is established | Key consideration |
|---|---|---|---|
| Zendesk AI agents | Teams prioritizing a native Zendesk setup | Agents can use trusted knowledge sources, procedures, authorized actions, and connections to other systems. AI agents are included in Suite, with plan-based automated-resolution allowances. | Usage allowances vary by plan; Copilot is a separate paid add-on. New AI agents cannot serve messaging and email simultaneously according to current help guidance; separate agents may be needed by channel. |
| Web Messenger with Sunshine Conversations | Teams that need more customization and control | Zendesk describes this as a do-it-yourself route for a customizable, asynchronous chatbot. | Sunshine Conversations requires a separate license; the available material does not establish a universal implementation price. |
| Third-party marketplace bot | Teams seeking a vendor-built bot integrated with Zendesk | Zendesk supports marketplace bots, which can act as first responders; developer documentation describes bot integration and OAuth requirements. | Channels, workflows, pricing, setup, and current listing status are vendor-specific and must be checked for the particular bot. |
The table reflects Zendesk documentation edited in 2026. Plan allowances and configuration can differ by account. See Zendesk’s AI offerings overview and its AI-agent setup guidance.

1. Zendesk AI agents: the native starting point
Zendesk’s AI agents are the most direct option for teams that want automated customer interactions inside the Zendesk environment. Zendesk says agents can answer from trusted knowledge sources, follow procedures, take authorized actions, and connect to other systems. This makes the distinction between an answer bot and an action-taking agent important: a team should define which sources the agent may rely on and which actions its permissions allow.
Plans, usage, and channels
Zendesk’s September 2026 documentation says AI agents are included in Suite and usage is measured through automated resolutions, with allowances based on plan. It does not establish one universal price or allowance for every account, so a flat cost comparison cannot be made from the published material here. Copilot is a separate paid add-on, not a synonym for the included AI-agent capability. Review the plan-specific details in Zendesk’s AI offerings overview.
Zendesk’s current help material says one new AI agent cannot work across messaging and email at the same time; separate agents are needed by channel type. Confirm how that constraint applies to your account and desired configuration. The source material does not establish support for every social or voice channel across every configuration.
Migration implications
Zendesk announced a phased rollout beginning May 11, 2026, simplifying AI-agent packaging and removing the Essential-versus-Advanced distinction. Its September migration guidance says technical development for AI agents–Essential and legacy bot-builder features stopped on August 31, 2026, with removal due in December 2026. Migration may involve rebuilding agents and creating separate agents for different channel types; complex legacy setups may need expert help. Check the current migration instructions and account-specific dates before scheduling the change: expanded access announcement and migration guidance.

Zendesk presents Web Messenger with Sunshine Conversations as a do-it-yourself approach for a customizable, asynchronous chatbot. This is a better match for teams that need to shape the experience and integration around their own workflows than for teams seeking a ready-made, independently ranked bot. Zendesk states that Sunshine Conversations requires a separate license; the cited material does not give a universal license price.
A custom route shifts more responsibility to the team and its implementation partner: specifying how the bot behaves, what systems it connects to, what actions it can take, and how a conversation passes to a human. Zendesk’s chatbot-options guidance describes this path. The available information does not establish its implementation cost, delivery timeline, or channel coverage for every build.
3. Third-party marketplace bots: choose by verified fit
Zendesk says teams can connect third-party bots through the Zendesk and Sunshine Conversations marketplaces. A marketplace bot may act as the first responder, but the vendor determines its features and setup. That makes the specific listing—not the general category—the unit to evaluate. Confirm the bot’s current availability and documentation in the Zendesk Marketplace.
Ada as a documented vendor lead
Ada’s vendor-authored brochure describes an Ada chatbot platform integrated with Zendesk. That establishes a vendor claim about an integration, not independent proof of performance, superiority, current marketplace listing status, or current commercial terms. See Ada’s Zendesk brochure. The available sources do not provide a comparable current price, plan allowance, or independently verified channel matrix for Ada, so those details should not be treated as established here.
What marketplace integration requires
Zendesk’s developer documentation describes how a marketplace bot is integrated and the OAuth requirements involved. The implementation details are relevant both to teams selecting an existing bot and to developers building one. Review Zendesk’s marketplace bot guide alongside the individual vendor’s current listing and setup documentation.
How to compare the options for your support operation
Compare each candidate against the same workload and service rules. A bot that answers common questions but cannot complete the customer’s next step may not reduce the work your team needs to handle.
- Channels: List the actual entry points your customers use—messaging, email, web forms, voice, and relevant social channels. Confirm support for each one in the exact product configuration, and account for Zendesk’s documented channel-specific AI-agent constraint.
- Integration depth: Distinguish Zendesk-native functionality from a marketplace integration and a custom Sunshine Conversations build. Ask what data, ticket context, and conversation history the bot can access.
- Tasks and permissions: Separate knowledge-based replies from procedures, authorized actions, and API connections. Define what the agent can do without approval and which situations must be handed to a person.
- Handoff and governance: Specify escalation triggers, human ownership, permissions, monitoring, and how incorrect or unresolved responses are reviewed.
- Measurement and total cost: Identify how the provider defines a resolved issue, what usage is included, what triggers extra charges, and whether separate add-ons or licenses apply. Estimate cost against your own ticket volume rather than comparing unlike allowance metrics.
- Migration burden: Inventory legacy bot-builder dependencies, channel-specific agents, and workflows that must be rebuilt. Include the December 2026 removal schedule in planning.
A practical evaluation sequence
- Inventory the current Zendesk setup. Record channels, legacy bot-builder workflows, knowledge sources, connected systems, and the actions agents currently perform.
- Choose the implementation path. Start with native AI agents for a platform-native route, consider Sunshine Conversations for a custom build, or shortlist a third-party bot for vendor-provided capabilities.
- Map the customer journey. For each frequent request, define what the bot should answer, what it may change or initiate, and the point at which a human takes over.
- Check exact channel and account fit. Verify the candidate’s current documentation and listing, then confirm Zendesk account eligibility, channel configuration, and any need for separate agents.
- Model cost at your volume. Compare resolution definitions and included usage with your expected workload; include licenses and paid add-ons where relevant.
- Plan migration and governance. Decide what must be rebuilt, who approves permissions, how conversations are monitored, and how unresolved or risky cases reach staff.
What is not established about chatbot performance
The available sources do not establish an independent head-to-head comparison, a named performance statistic suitable for ranking, or a universal best provider. Zendesk’s statements about automation are company product claims, not independent comparative results. In a May 19, 2026 announcement, Zendesk CEO Tom Eggemeier said, “The era of the chatbot – the era of frustration and deflection – is over.” That is company positioning, not evidence that one Zendesk option performs better than another. See the May 2026 announcement.
