Open-source self-hostable CRM vs. AI-native modern CRM.
Twenty is an open-source CRM that launched in 2023 as a reaction to Salesforce's complexity and cost. It is free, self-hostable, and has a flexible data model. Attio is a proprietary AI-native CRM at $34-119/user/month, built for technical startups that want a modern alternative to HubSpot or Salesforce. Both position themselves as modern CRMs for teams that have outgrown basic contact managers. The differences come down to the open-source trade-off — Twenty is free but early-stage and requires technical setup; Attio is paid but more polished and actively developed.
Open-source vs. proprietary
Twenty is open-source under the AGPL license. You can inspect the code, self-host it on your infrastructure, and contribute to development. For technical teams who want full control over their data and no SaaS dependency, this matters. Attio is proprietary — you get a polished product but no access to the underlying code and no option to self-host. All your data lives in Attio's cloud.
Maturity and reliability
Twenty is early stage. It ships fast, the community is active, and the roadmap is ambitious — but it is not the tool you reach for when you need a CRM that has been battle-tested across thousands of companies. Attio is more mature, has better documentation, and has a full-time team focused on stability and support. For companies where CRM reliability is critical, Attio's track record is more bankable.
AI features and automation
Attio has invested heavily in AI — automatic contact enrichment, AI-powered insights, and tight integrations with the modern GTM stack. Twenty has AI features on the roadmap and some in beta, but it is earlier in development. If AI-native workflows — like automatically enriching a contact when added or surfacing pipeline insights — are important to your team, Attio's implementation is more mature.
| Attio | Twenty | |
|---|---|---|
| Pricing | $34–119/user/month | Free (self-hosted) — cloud version in development |
| Open source | No | Yes — AGPL, self-hostable |
| AI features | Yes — enrichment, insights, AI-native | Early stage — roadmap items |
| Data model flexibility | Very high — custom objects + relationships | High — flexible but less mature tooling |
| Setup complexity | Medium — cloud, works immediately | High if self-hosting — technical setup required |
| Support | Yes — documentation + team support | Community-based |
| Maturity | More mature — stable, well-documented | Early stage — active development |
| Best for | Technical teams wanting a polished modern CRM with active development and support | Technical teams comfortable self-hosting who want a free, customizable CRM with no SaaS lock-in |
The verdict
Twenty for technical teams who are comfortable self-hosting, want zero ongoing cost, and value the ability to inspect and own the codebase. The trade-off is early-stage maturity — you will hit rough edges, and setup is not trivial. Attio for teams that want a polished, AI-native modern CRM with active development, full support, and no infrastructure to manage. Attio's data model flexibility is comparable to Twenty's, but you get it in a product that has been running in production for thousands of companies.
Can Twenty handle a real sales pipeline, or is it still too early?
Twenty has working pipeline management, deal stages, and contact tracking. For a small technical team willing to accept some rough edges, it is functional. It is not at feature parity with Attio or HubSpot on pipeline management, reporting, or integrations — but it is progressing quickly. Check the GitHub repo for current status before making a decision.
Is there a hosted version of Twenty I can use without self-hosting?
Twenty has been working on a cloud-hosted version, but as of early 2025, self-hosting is the primary path for full control. Their cloud offering has had limited availability. Check twenty.com for current cloud access status.
How does Attio's pricing compare at team scale?
Attio's Plus plan is $34/user/month and covers most small team needs. Pro is $119/user/month and adds advanced automation, AI credits, and API access. For a 5-person team on Plus, that is $170/month versus free on Twenty. The question is whether the polished UX, support, and mature AI features are worth $2,040/year for your team.
