Kantos vs HubSpot
Looking for a HubSpot alternative?
HubSpot is a capable, mature platform with a large ecosystem. But for many growing businesses the reality is contact-based pricing that climbs as your database grows, and essential capabilities — custom objects, advanced automation, deeper API access — gated behind higher tiers. Kantos takes the opposite approach: a fully customizable data model, automation, and full API access on every paid plan, at transparent flat pricing, with AI integrated at the core.
| Feature | Kantos | HubSpot |
|---|---|---|
| Entry pricing | Free tier; paid from $19/mo (flat) | Free tier; paid plans scale with seats and marketing contacts |
| Pricing model | Flat plans, no per-contact fees | Contact-based pricing that grows with your database |
| Custom objects | Unlimited, on every plan | Available on higher (Enterprise) tiers |
| Automation | Included on all plans | Advanced workflows on Professional+ tiers |
| REST API access | Full access on all paid plans | Rate-limited; broader access on higher tiers |
| AI agent access (MCP) | Native MCP server, 60+ tools, OAuth 2.0 | AI features as add-ons / assistants |
| Data ownership | Full export + API on every plan | Export available; lower tiers limit API |
Why teams choose Kantos
- Unlimited custom objects and fields on every plan — model your real business, not just Contacts/Companies/Deals.
- Full REST + MCP (Model Context Protocol) API access on all paid plans, so AI agents like Claude can operate your CRM directly.
- Transparent flat pricing with no per-contact charges — your bill does not grow just because your database did.
- Automation, custom data model, and data export available without an enterprise upgrade.
Where HubSpot wins
We'd rather be honest. HubSpot is the better fit if you need:
- A large marketplace of integrations and certified solution partners.
- Built-in marketing suite: CMS, landing pages, and a mature email/marketing hub.
- Extensive documentation, community, and brand recognition.
Kantos vs HubSpot: FAQ
Is Kantos a good HubSpot alternative?
Kantos is a strong HubSpot alternative for growing businesses that need a fully customizable data model, automation, and full API access without enterprise-tier pricing — especially teams whose workflows do not fit the standard Contacts/Companies/Deals structure. If you primarily need an all-in-one marketing suite with a large partner ecosystem, HubSpot may suit you better.
How does Kantos pricing compare to HubSpot?
Kantos uses transparent flat plans (Free, then $19/mo and $49/mo) with no per-contact charges, so your price does not increase as your contact list grows. HubSpot uses contact- and seat-based pricing where costs scale with your database and tier.
Does Kantos have an API like HubSpot?
Yes. Kantos exposes a REST CRM API for objects, fields, records, automations, and media with API-key authentication, plus a Model Context Protocol (MCP) server with 60+ tools so AI agents can query and manage your CRM directly. API access is included on every paid plan.
Can I migrate my data from HubSpot to Kantos?
Yes. Kantos supports CSV/Excel import with field mapping and duplicate detection, and its custom data model lets you recreate your existing objects and fields. Reach the founding team via live chat or support@kantos.ai for migration help during early access.
