TL;DR verdict

Twenty is an open-source CRM built for teams that want full data ownership and a modern UI without Salesforce complexity. Close is a purpose-built inside-sales tool with native calling, SMS, and power dialers. They solve fundamentally different problems: Twenty is for teams that want to own their CRM infrastructure; Close is for SDR teams that live on the phone. If your sales motion is email-heavy and you want self-hosted flexibility, Twenty wins. If your reps make 50+ calls a day and need call coaching, Close is the better tool.

Pipeline and data model

Winner: Twenty

Twenty offers a flexible, graph-style data model that lets teams define custom objects and relationships without code. It mirrors how modern RevOps teams think about accounts, contacts, and opportunities. Close's pipeline is purpose-built for inside sales: it tracks leads through call-based sequences and has limited support for complex deal structures or non-linear pipelines. If your data model is simple and your team needs highly customizable object relationships, Twenty has the edge. For a standard lead-to-close pipeline driven by calling activity, Close's opinionated structure is actually a feature — it enforces discipline and reduces configuration overhead.

Ease of adoption

Winner: Close

Close is faster to adopt for sales reps because it strips away everything that isn't directly tied to making calls, sending emails, and closing deals. The UI is focused, onboarding takes hours not days, and reps don't need admin support to get productive. Twenty requires self-hosting setup, which means DevOps involvement before a single rep logs in. For non-technical teams, that's a meaningful barrier. For engineering-led companies already running their own infrastructure, Twenty's setup is routine. The winner here depends on who owns the rollout: if it's a sales manager, Close wins; if it's an engineering team, Twenty is manageable.

Calling and communication

Winner: Close

Close's built-in calling, power dialer, and SMS are its core differentiator. Reps can call from inside the CRM, recordings sync automatically, and call outcomes update lead status without manual entry. Close also offers predictive dialing and voicemail drop. Twenty has no native calling features — you'd need to integrate a third-party tool like Aircall or Twilio and build custom workflows to approximate what Close offers out of the box. If calling volume is central to your sales motion, this is not a close comparison: Close wins decisively. Twenty is not positioned as a calling CRM.

Reporting and forecasting

Winner: Close

Close has strong activity-based reporting: call duration, call outcomes, sequences, email open rates, and deal velocity. It's built to measure what inside sales teams actually care about. Twenty's reporting is still maturing — as an early-stage open-source product, its analytics capabilities are limited compared to mature commercial CRMs. Custom reporting requires direct database queries or external BI tools. For teams that need pipeline forecasting, quota tracking, and activity dashboards without building them from scratch, Close is more production-ready today. Twenty's reporting will improve, but it's not there yet.

Integration ecosystem

Winner: Close

Close integrates natively with Zapier, Segment, Slack, and major email tools, and has a well-documented REST API used by thousands of customers. Twenty is open-source and API-first, which means integrations are technically unlimited — but they require development work. There's no native Zapier integration at scale, and the marketplace is thin compared to mature SaaS CRMs. For teams that want integrations that work out of the box without engineering involvement, Close has the advantage. For teams building custom workflows and happy to write code, Twenty's API-first design is actually more powerful in the long run.

Cost at team scale

Winner: Twenty

Twenty's open-source license means the CRM itself is free — you pay for hosting and internal maintenance, not per-seat SaaS fees. For a 10-person sales team, Twenty can be dramatically cheaper than Close's $49/seat/month starting price, which quickly compounds as you add seats and usage. Close's pricing also scales with features: power dialer, predictive dialing, and call coaching are locked to higher tiers. For engineering-led companies that can absorb infrastructure costs, Twenty's total cost of ownership is substantially lower. For companies without DevOps resources, the hidden cost of Twenty is engineering time, which can exceed Close's subscription fees.

Pricing deep-dive

Twenty

  • Free plan: available for evaluation or limited production use.
  • Entry paid tier: starts from free with feature or usage upgrades on paid tiers.
  • Pricing model: open-source; license is open-source; deployment type is open-source.
  • Open-source: subscription cost may be replaced by hosting, upgrades, and internal maintenance.

Close

  • Free plan: not listed publicly.
  • Entry paid tier: starts at $49/month.
  • Pricing model: paid; license is proprietary; deployment type is saas.

Pricing verdict: Twenty is free to use but requires hosting infrastructure, so real cost depends on your engineering capacity. Close starts at $49/seat/month with no free plan — for a 5-person team that's $245/month minimum before add-ons. At 15+ seats, Close's cost becomes significant. Twenty wins on pure subscription cost; Close wins on predictability and zero infrastructure overhead. If your team can self-host, Twenty is cheaper at scale. If you need a fully managed solution with no engineering overhead, Close's pricing is reasonable for what it delivers.

How to migrate from Twenty to Close

Data export
Export contacts, companies, deals, and activity history from Twenty via its REST API or direct database export. Twenty stores data in PostgreSQL, so you can export structured CSVs for all core objects. Keep a read-only database snapshot until your Close workflows have survived at least one full sales cycle.
Import support
Close supports CSV import for leads, contacts, and organizations via its web importer. Custom fields need to be created manually before import. Use Close's API for bulk imports with relationship preservation. Map Twenty's custom objects to Close's lead/contact/opportunity structure before migrating.
Does not migrate
Twenty's custom object relationships, automation workflows, self-hosted integrations, webhook configurations, and any custom views or saved filters will need to be rebuilt manually in Close. Call scripts and sequences must be created from scratch in Close.
Time estimate
Plan two to three days for a small team with clean data. Allow one to two weeks for mid-size teams with complex custom fields or data quality issues. Add time if compliance review is required or if you need to migrate historical call data from a third-party tool.

What real users say

Twenty: Twenty users consistently praise its modern UI, flexible data model, and genuine open-source ethos with an active GitHub community. Complaints center on early-stage instability, limited native integrations, and the engineering overhead required for self-hosting and upgrades.

Close: Close users love its focused, no-distraction interface for high-volume calling teams and praise the built-in power dialer and automatic call logging. Common complaints are around pricing at scale, limited customization for non-standard sales processes, and reporting that favors activity metrics over revenue forecasting.

Final verdict

Choose Twenty if...

  • Choose Twenty if your team needs a self-hosted, open-source CRM and has engineering capacity to manage infrastructure and integrations.
  • Choose Twenty if data ownership, privacy compliance, or air-gapped deployment is a hard requirement that rules out SaaS CRMs.
  • Choose Twenty if your sales motion is primarily email and relationship-based and you don't need native calling or SMS features.

Choose Close if...

  • Choose Close if your sales team makes high-volume outbound calls and needs built-in dialing, power dialer, and automatic call logging.
  • Choose Close if you want a production-ready, fully managed CRM your sales reps can adopt in a day without involving engineering.
  • Choose Close if your sales process is standardized around inside sales sequences and you need activity-based reporting and quota tracking.

Consider neither if: Consider neither if you need a full CRM platform with deep marketing automation, enterprise reporting, and a large partner ecosystem — look at HubSpot or Salesforce. Also reconsider if your team is primarily relationship-driven without a structured sales pipeline; a lighter tool like Attio may be more appropriate.
