FAQ

Frequently asked questions

Intercom vs Crisp vs Drift?

Intercom: premium, $74+/mo, best AI agent and feature depth. Crisp: budget-friendly, $25-95/mo, similar core features. Drift: B2B-focused, ABM features, $500+/mo, premium positioning. For B2B SaaS at scale: Intercom. For early-stage: Crisp. For enterprise sales: Drift.

Will Intercom slow my page?

The Intercom widget loads ~200KB but defers until after page load, so it doesn't affect LCP. Some impact on INP if you have many other scripts; for fast-page-priority sites, consider Crisp (lighter weight).

Can Intercom integrate with HubSpot?

Yes — native HubSpot integration syncs Intercom conversations to HubSpot contacts and pulls contact properties into Intercom. Useful for B2B sales teams that run CRM in HubSpot but chat in Intercom.

What about live chat for ecommerce?

Intercom works for ecommerce but is overkill for most. For pure ecommerce, use Gorgias or Zendesk (purpose-built). For service-business ecommerce hybrid (e.g., online courses, info-products), Intercom is fine.
