Subbly vs Medusa
Side-by-side trajectory, velocity, and editorial themes.
Subbly rebuilds churn prediction in-house — 68% more accurate, 3x lift on at-risk flagging — alongside steady AI Builder gains.
Subbly is doubling down on the two systems that matter most for subscription commerce: churn intelligence and AI-driven storefront building. The May 6 release replaced its third-party churn engine with an in-house model that's 68% more accurate and flags subscribers who actually churn at nearly 3x the rate. Cancellation now supports immediate or end-of-period semantics, account security adds biometric 2FA and anomaly detection, and AI Builder keeps adding capabilities — Skills, deeper subscription knowledge, an experimental design model, metafield generation.
Investment is splitting cleanly: ML/data science for retention (where Subbly wins by being subscription-native), and AI Builder for storefront acquisition (where Subbly wins by being subscription-aware). Bringing churn prediction in-house is a moat play — proprietary subscription data now feeds a proprietary model, raising switching costs versus Recharge or Bold.
Expect churn-risk scores to feed back into AI Builder for retention-optimised offer flows, and a paid 'churn intelligence' or 'win-back automation' tier built on the new model. AI Builder will likely keep widening its skill catalog and may expose its agent surface via API or MCP next.
Medusa is settling into a steady cadence of point releases while rebuilding its starter around a monorepo.
Medusa is in maintenance mode on the 2.14 line, shipping two patch releases (v2.14.1, v2.14.2) in the past three weeks alongside cleanup work on snapshot files. The headline change of the cycle was v2.14.0, which restructured create-medusa-app into a monorepo with separate backend and storefront packages. The project continues to draw broad contributor participation, with the v2.14.0 release crediting 15 contributors.
After a heavy second-half-2025 push that delivered experimental Translations, HMR for the backend, and priority-based event processing, the project has shifted from feature expansion to consolidation. Recent work is dominated by version bumps, regression fixes, and starter ergonomics rather than new capability surface. The monorepo starter is the signal that the team is now thinking about how teams adopt and structure Medusa, not just what it can do.
Expect another patch release on the 2.14 line within the next few weeks, then a 2.15 cut that builds on the new monorepo starter — most likely tighter storefront-backend conventions, or graduating Translations or HMR out of experimental.
