Horizon EDA vs Spectra
A side-by-side editorial comparison of Horizon EDA and Spectra — release velocity, themes, recent moves, and the top alternatives to consider.
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 Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.

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
5.0DESIGN
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
◆ Current state
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
◆ Where it's heading
After the AI page import push in September, releases have been about trust in the output: render it correctly, make it count for SEO, now make it fast and accessible. The Pro add-on follows the same cadence with design-token and dynamic-data fixes.
◆ Prediction
Expect accessibility passes on other interactive blocks such as tabs or accordions, following the Slider, alongside further Pro fix rounds.
