Capacity alternatives: 12 tools compared (October 2026)

Tidio is customer service software for small and midsize businesses, especially online stores. It combines live chat, a help desk and chatbot Flows with Lyro, an AI agent that answers customer questions from the company's own support content and hands complex cases to people.

Key functions

• Lyro AI Agent answers customer questions from your own support content on website chat, WhatsApp, Instagram and Messenger
• Lyro Smart Actions handle tasks such as order updates or lead qualification through connected systems
• Product recommendations drawn from the live store catalog

Compared with Capacity

• Publishes a price (from $24.17 per month); Capacity quotes on request.
• Offers a free trial; we found none for Capacity.
• Can store data in the EU; Capacity states no EU option.
• Different pricing model: freemium instead of usage-based.

Check before buying: Estimate billable human conversations and Lyro conversations separately, because both drive the monthly price. Data is stored in the EEA, but the contracting party is US-based and the AI terms list Anthropic in the US as a subprocessor. US buyers should review CCPA duties. Under Article 50 of the EU AI Act, customers must be told they are talking to an AI agent. SSO is listed only for Premium.

• Offers a free trial; we found none for Capacity.
• Can store data in the EU; Capacity states no EU option.
• Names 4 security certificates, Capacity 1.

Check before buying: Outcome pricing makes costs rise with volume, so model expected resolutions and the monthly minimum for standalone use. Choose EU data residency if you serve European customers, and review the DPA and sub-processors in the trust center. SSO requires the Expert plan.

Forethought provides AI agents for customer support that resolve requests on chat, email, voice and Slack, sort and route tickets and score service quality. They run on top of existing helpdesks such as Zendesk, Salesforce or Intercom.

Key functions

Compared with Capacity

• Strong in the same markets as Capacity: United States.

Check before buying: Ask how the outcome-based part of the price is counted and what happens above plan limits. The subprocessor list names AWS, Google and Microsoft hosting and OpenAI, Groq and Mistral models, all in the US, and Forethought may also use Zendesk subprocessors. Clarify the product roadmap after the Zendesk acquisition. AI QA scores individual reps, which touches employee monitoring rules in some US states and the EU.

Key functions

• Freddy AI Agent resolves customer requests and takes actions

Key functions

• Offers a free trial; we found none for Capacity.
• Can store data in the EU; Capacity states no EU option.
• Different pricing model: per user instead of usage-based.

Check before buying: Seat prices rise with the plan, and AI features are add-ons outside Enterprise, so model the total per seat plus Autopilot usage. Request the EEA hosting region before setup; the subprocessor list names OpenAI and Anthropic in the US and Azure in several European countries for AI functions. Smart QA scores individual agents, which touches employee monitoring rules in some US states and the EU.

The vendor states that customer data is not used to train OpenAI's base models. Budget AI Answers resolutions separately from seats, and note that SAML single sign-on is an add-on below the Pro plan.

Ask which of the language models process your data, and review the published data processing addendum.
