Blockly vs Open edX
A side-by-side editorial comparison of Blockly and Open edX — release velocity, themes, recent moves, and the top alternatives to consider.
Blockly vs Open edX: at a glance
What is Blockly?
Post-v13 cleanup: three beta tags in one evening, two of them carrying nothing at all.
Blockly is servicing the v13 line it opened in June with keyboard navigation and screenreader support on by default. The 13.2.2 beta train tagged three times in under three hours, but only beta.0 carries changes — an undo-stack corruption fix, a nested-tree traversal speedup, and focus restoration on toast dismissal. beta.1 and beta.2 record an empty commit range.
What is Open edX?
Open edX is rebuilding course authoring around reusable Libraries.
The Ulmo release in January 2026 lets authors build complete course structures inside Libraries and sync them into multiple courses with visual diff before apply. That extends the Teak (mid-2025) Libraries work and the Sumac (Feb 2025) Content Libraries beta. Content Tagging (March 2025) sits underneath as the indexing layer making reuse navigable.

Blockly
5.0EDTECH
Post-v13 cleanup: three beta tags in one evening, two of them carrying nothing at all.
◆ Current state
Blockly is servicing the v13 line it opened in June with keyboard navigation and screenreader support on by default. The 13.2.2 beta train tagged three times in under three hours, but only beta.0 carries changes — an undo-stack corruption fix, a nested-tree traversal speedup, and focus restoration on toast dismissal. beta.1 and beta.2 record an empty commit range.
◆ Where it's heading
The work since v13.0.0 is consolidation around focus, rendering, and performance rather than new surface area — insertion markers rewritten for memory, connection-database updates sped up, field labels made translatable. Accessibility remains the organizing concern, now expressed as correctness fixes in the machinery that shipped rather than new capability. The rapid empty beta tags suggest release automation firing on non-code commits.
◆ Prediction
Expect a 13.2.2 final shortly, continuing the pattern of small fix batches on the v13 line. Nothing in these entries points to a v14 or a new feature theme.
Open edX
0.0EDTECH
Open edX is rebuilding course authoring around reusable Libraries.
◆ Current state
The Ulmo release in January 2026 lets authors build complete course structures inside Libraries and sync them into multiple courses with visual diff before apply. That extends the Teak (mid-2025) Libraries work and the Sumac (Feb 2025) Content Libraries beta. Content Tagging (March 2025) sits underneath as the indexing layer making reuse navigable.
◆ Where it's heading
Open edX has spent the last four named releases — Sumac, Teak, Ulmo, with Content Tagging in between — turning Libraries into the first-class authoring primitive instead of treating each course as a silo. The product is moving from one-course-at-a-time authoring toward a content-reuse model that resembles how textbook publishers and large training orgs actually want to work.
◆ Prediction
The next release will likely close more of the Libraries-to-course gap: branching/versioning of library content, finer-grained sync controls, and probably AI-assisted authoring on top of the tagged-and-libraried content base.
