Which one to pick
Choose Attio if
- You want a free CRM for up to 3 seats and 50,000 records with API, webhooks, workflows and MCP.
- You want the database to stop duplicate companies and people: upsert on domain or email returns the existing record.
- Your integrations need a high per-second rate: 100 reads and 25 writes a second.
- You want custom objects modelled as relational records (Pro and up).
Choose HubSpot if
- You load records in bulk: batch upsert takes 100 records per call and the Imports API takes millions of rows a day.
- You want a low entry seat price: Starter lists at $20 a seat a month, with a limited-time offer for new customers.
- You want email sequences and marketing tools in the same platform.
- You build in Node.js, PHP, Python or Ruby and want an official API client.
If neither fits: A CRM stores your own records. If the real job is finding emails for a list of people, find and verify them first, then load them into whichever CRM you pick.

Questions people ask
Is Attio cheaper than HubSpot?
At entry level HubSpot's list price is lower: Starter is $20 a seat a month, against $35 a user a month billed annually for Attio Plus. Higher up, Attio Pro is $79 a user a month billed annually and HubSpot Professional is $90 billed annually plus $1,500 onboarding. Both have a free plan.
Which free plan gives more?
Attio Free covers up to 3 seats, 50,000 records and up to 3 objects, with API, webhooks, workflows and MCP. HubSpot's free tools cover up to 2 users and 1,000 contacts, with API access and no workflows.
How do Attio and HubSpot handle duplicate companies created by API?
Attio treats company domain as unique: a plain create with an existing domain is rejected, and an upsert updates the existing company. HubSpot dedupes contacts on email, but companies created through the API are not deduplicated by domain, so search before you create.
Can I bulk import records through the API?
HubSpot has batch endpoints of 100 records per call and an Imports API that takes up to 80,000,000 rows a day. Attio's API has no batch record endpoint, so records go one per call within its 25 writes a second.
Do Attio and HubSpot have MCP servers?
Yes. Attio's is at https://mcp.attio.com/mcp and HubSpot's at https://mcp.hubspot.com. Both sign in with OAuth and can read and write CRM records.
