Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.
AI wireframing tool closing the loop from prompt to design to code
Visily's dated update posts show a steady march up the fidelity ladder. March added code generation for designs, a Plan Mode for ideation ahead of AI generation, and unsupported font replacement on Figma imports. February brought Figma import itself and blur effects; January added Design Instructions for consistent output and a Deep Design mode. Earlier releases covered shadows, a browser capture overlay, an AI Content Filler and interactive dropdowns.

This is an early-life product being hardened in public, and the choices reveal the audience. Version rollback is a safety net for agencies who update client sites and need an exit; theme colour sync is about blocks inheriting the site palette instead of fighting it. Both point at Spectra Blocks being positioned as infrastructure a professional builds on rather than a set of decorative blocks.
Expect the 1.0.x fix cadence to continue for several more weeks before the block library itself starts expanding, with Pro staying a release or two behind the free edition. The changelog bodies are truncated in this feed, so which specific blocks ship next is not visible from here.

Earlier releases covered shadows, a browser capture overlay, an AI Content Filler and interactive dropdowns.
The arc runs from making generated designs look right to making them useful downstream. Design Instructions and Deep Design addressed consistency and polish; Figma import opened a migration path in; code generation opens an exit path out. Plan Mode is the interesting addition — separating intent from generation, rather than treating one prompt as the whole brief.
With import from Figma and export to code both in place, expect the round trip to tighten — keeping generated code and design in sync is the obvious unsolved half, though the entries do not describe work on it yet.
