Horizon EDA vs Spectra

Horizon EDA vs Spectra: at a glance
What is Horizon EDA?
Horizon EDA ships one feature release a year and spends the rest fixing what it broke.
Horizon EDA runs a slow, deliberate cadence: roughly one named feature release per year — Kepler in 2023, Luna in 2024, Mirage in 2025 — followed by two bugfix releases in the same series. The 2.7 series added pick-and-place export save/load, polygon pad rendering performance, project pool cache updates from the editors, and parameter fixing in the package editor. Its two patch releases were crash fixes and export correctness, mostly around silkscreen and PDF output.
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.
Horizon EDA vs Spectra: editorial side-by-side
Horizon EDA
0.0DESIGN
Horizon EDA ships one feature release a year and spends the rest fixing what it broke.
◆ Current state
Horizon EDA runs a slow, deliberate cadence: roughly one named feature release per year — Kepler in 2023, Luna in 2024, Mirage in 2025 — followed by two bugfix releases in the same series. The 2.7 series added pick-and-place export save/load, polygon pad rendering performance, project pool cache updates from the editors, and parameter fixing in the package editor. Its two patch releases were crash fixes and export correctness, mostly around silkscreen and PDF output.
◆ Where it's heading
The feature work tracks a single theme across all three named releases: making the editors forgiving. Undo and redo that never forgets, undo/redo of selection, sticky selection and configurable selection modifiers arrived in 2.5 and 2.6; 2.7 pushed into export workflows and rendering speed. The bugfix pattern is consistent too — most patches land in the board editor, which is where the complexity lives.
◆ Prediction
On the established cadence a 2.8 feature release is due, and the recent bugfix concentration suggests export and silkscreen handling get attention in it.
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.
