installHosted cloud signup or official one-line/Docker Compose self-host install
dataCRM records and configuration in PostgreSQL; files in local storage or S3-compatible object storage on the selected host

licenseAGPL-3.0
runsyour server

runsyour machine or their cloud
installOne-click Frappe Cloud signup or the official Python easy-install deployment script on your server
dataCRM DocType records and attachments in the Frappe site database/files, on Frappe Cloud or the user's server
the catch vs AttioFrappe CRM is less flexible and polished than Attio for building custom relationship objects, live views, and enriched records.

Easiest to get running
Monica — a one-click install, no server to maintain.
Most proven

what you give up by leaving Attio
- real-time data model, enrichment, email sync, automations, and collaborative polish
- automatic email and calendar capture
- data enrichment
- large integration ecosystem

why people still pay for Attio
People still pay for Attio because CRM value compounds as the system becomes the shared memory of every customer interaction and embeds itself in the rest of the stack. The recurring cost buys deduplication, permissions, imports, sync, enrichment, email capture, automations, backups, and audit history, not just the visible interface. If none of that applies to you, any pick above saves $528 a year.
