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 maintenance branches carrying security backports, not features
The visible stream is release-branch commits rather than named releases, and the recent ones are all corrective. Two July entries backport the same fix — an authorization gap where CourseTeamManageAPIView required only authentication, letting any enrolled learner call the endpoint. Earlier entries block SSRF in SAML metadata fetching by validating the URL against loopback, link-local, reserved and private ranges, add LTI launch logging, and normalize block structure keys.

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 maintenance branches carrying security backports, not features
◆ Current state
The visible stream is release-branch commits rather than named releases, and the recent ones are all corrective. Two July entries backport the same fix — an authorization gap where CourseTeamManageAPIView required only authentication, letting any enrolled learner call the endpoint. Earlier entries block SSRF in SAML metadata fetching by validating the URL against loopback, link-local, reserved and private ranges, add LTI launch logging, and normalize block structure keys.
◆ Where it's heading
This window shows the maintenance side of a large deployment-driven platform: fixes land on master and are backported across named release branches (teak, ulmo, verawood) so operators on older lines get them. The security items share a shape — endpoints and integrations that trusted their callers more than they should. Nothing here indicates feature direction, because feature work does not surface in this branch stream.
◆ Prediction
Expect continued backporting across the active named branches, since the same authorization fix already landed on two of them within a minute of each other. What ships in the next named release is not visible from these entries.
