Fat Free CRM vs IntegCRM: 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 IntegCRM?
IntegCRM keeps building out invoicing, bookings, forms and email for service businesses.
IntegCRM ships about one notable feature a month, focused on the operational side of a services CRM: invoices, payments, bookings, forms and now marketing email. The changelog posts are headlines with category tags and little detail, so the depth of each change isn't visible. The latest adds mobile view controls to the email builder.
Fat Free CRM vs IntegCRM: editorial side-by-side
Fat Free CRM
0.0CRM
Fat Free CRM's only tracked release is a test tag that pins the Ruby platform back to 3.4.
◆ 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.
IntegCRM
5.0CRM
IntegCRM keeps building out invoicing, bookings, forms and email for service businesses.
◆ Current state
IntegCRM ships about one notable feature a month, focused on the operational side of a services CRM: invoices, payments, bookings, forms and now marketing email. The changelog posts are headlines with category tags and little detail, so the depth of each change isn't visible. The latest adds mobile view controls to the email builder.
◆ Where it's heading
Payments and invoicing come up more than anything else: payment schedule notifications, editable bookings, custom invoice layouts. Forms and surveys get a steady second track, and the email builder fix shows marketing tools getting attention too. The pattern is a CRM growing toward running a small service business's whole billing and outreach workflow, not just its pipeline.
◆ Prediction
More invoice, payment and email-builder customization is the most likely next step. With such thin release notes, the specific feature is hard to call with confidence.
