Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Atomic CRM
- Positioned as a customizable starter, not a turnkey product
- Depends on Supabase, adding an external dependency
- Lacks marketing automation, telephony, and advanced reporting
- Small community and limited out-of-the-box integrations
Twenty
- Smaller ecosystem of integrations and marketplace apps versus Salesforce/AppExchange
- Workflow automation, reporting, and analytics are still maturing
- No mature mobile apps
- Younger product, so APIs and data model still evolve between releases
Bottom line
Both are a similar lift to self-host; choose Twenty for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
