Fat Free CRM vs Nutshell: at a glance
What is Fat Free CRM?
Fat Free CRM's only tracked release is a test tag that pins the Ruby platform back to 3.4.
Fat Free CRM, the open-source Rails CRM, has one tracked entry: an April 2026 GitHub release tagged "test" that normalizes the platform setting and drops back to Ruby 3.4. It is build configuration, not a feature release.
What is Nutshell?
Nutshell adds CallRail call attribution after a quiet September
Nutshell shipped a dense run of features in August: branching email Smart Sequences, per-user quotas, calendar invitations with video links, a reworked QuickBooks Online integration, RingCentral SMS sync, revenue installments and numeric custom fields. After more than a month with no entries, it is back with a CallRail integration that ties inbound calls to the marketing source that produced them.

◆ Current state
Fat Free CRM, the open-source Rails CRM, has one tracked entry: an April 2026 GitHub release tagged "test" that normalizes the platform setting and drops back to Ruby 3.4. It is build configuration, not a feature release.
◆ Where it's heading
One CI-facing tag is too little to read a direction from. The Ruby version pin hints at maintenance work keeping the app on a supported runtime rather than new CRM capability.
◆ Prediction
The entries don't support a confident prediction; a tagged versioned release would be the first signal of where the project is heading.

Nutshell adds CallRail call attribution after a quiet September
◆ Current state
Nutshell shipped a dense run of features in August: branching email Smart Sequences, per-user quotas, calendar invitations with video links, a reworked QuickBooks Online integration, RingCentral SMS sync, revenue installments and numeric custom fields. After more than a month with no entries, it is back with a CallRail integration that ties inbound calls to the marketing source that produced them.
◆ Where it's heading
Nutshell is folding jobs that usually need separate tools into the CRM: behavioral email, invoicing handoff, SMS and now call attribution. The newest move points the product toward small businesses that judge marketing spend by how often the phone rings, not only toward sales teams.
◆ Prediction
Expect more marketing-attribution reporting built on the CallRail data, since Smart Sequences and call tracking both feed the question of which channel produced a customer. The month-long gap makes the shipping cadence harder to predict.
