Blockly vs TAO Testing
A side-by-side editorial comparison of Blockly and TAO Testing — release velocity, themes, recent moves, and the top alternatives to consider.
Blockly vs TAO Testing: 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 TAO Testing?
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.

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.
TAO Testing
2.5EDTECH
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
◆ Current state
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.
◆ Where it's heading
TAO is maintaining several customer-pinned construct lines simultaneously and moving work between them rather than shipping forward on a single trunk. The version numbers run non-monotonically as a result — v55.0.1.13 is newer than v56.3.5.2 by date — so tag order says nothing about what a given release contains. Nothing here indicates development on new capability.
◆ Prediction
Expect more per-branch backport tags with contentless notes as features already merged upstream are pulled into supported lines. Whether dual preview reaches the v55 line is not visible from these entries.
