What is Sketch?
Sketch is clearing its feature-request backlog while the web app quietly becomes the main surface.
Sketch ships two named Mac releases a year — Dublin in April, Edinburgh in June — each bundling long-requested craft features: selection colors, independent borders, corner smoothing, a rebuilt eyedropper with color variables, multi-paste, and perceptual gradients. Point releases in between carry those features forward with fixes and nothing else. The web app is on its own track, most recently gaining a Command Bar, reworked notifications, and steady developer-handoff improvements.
What is Spectra?
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.
Sketch vs Spectra: editorial side-by-side
Sketch
5.0DESIGN
Sketch is clearing its feature-request backlog while the web app quietly becomes the main surface.
◆ Current state
Sketch ships two named Mac releases a year — Dublin in April, Edinburgh in June — each bundling long-requested craft features: selection colors, independent borders, corner smoothing, a rebuilt eyedropper with color variables, multi-paste, and perceptual gradients. Point releases in between carry those features forward with fixes and nothing else. The web app is on its own track, most recently gaining a Command Bar, reworked notifications, and steady developer-handoff improvements.
◆ Where it's heading
The Mac app's roadmap reads as debt repayment — features designers have asked about for years, plus performance work on symbols and Libraries — rather than any bid to change what the tool is. Momentum is shifting toward the browser, where collaboration, handoff, and navigation are getting the attention. The one forward-looking move sits outside the release line: a public skills repository giving AI agents reusable workflows against Sketch documents.
◆ Prediction
Expect the next named Mac release to continue the craft-feature backlog while the web app absorbs more workspace and handoff surface; agent-facing work will likely stay in the skills repo rather than the app itself.
Spectra
6.3DESIGN
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
