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 spends its first six weeks patching what 1.0 shipped.
Spectra Blocks and its Pro edition both launched in mid-July, and every release since has been a fix or a small addition. The window holds five patch releases across the free and Pro plugins, with automatic theme colour sync and version rollback the only additions a user would notice. The release notes carry What's Fixed headings with no fix list underneath, so the specifics are not readable from the feed.

Horizon EDA

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 spends its first six weeks patching what 1.0 shipped.
◆ Current state
Spectra Blocks and its Pro edition both launched in mid-July, and every release since has been a fix or a small addition. The window holds five patch releases across the free and Pro plugins, with automatic theme colour sync and version rollback the only additions a user would notice. The release notes carry What's Fixed headings with no fix list underneath, so the specifics are not readable from the feed.
◆ Where it's heading
Cadence is high and substance per release is thin, which is the normal shape of a young block plugin stabilizing against the range of themes and blocks it meets in the wild. Pro is patching at the same rate as free rather than pulling ahead, so the paid tier has not yet started to differentiate on features. The fixes cluster on styling and the Button block, pointing at cross-theme rendering as the current problem area.
◆ Prediction
Expect the patch cadence to hold until a 1.1 collects new blocks. Given the free and Pro split, the next real feature work most likely lands on the Pro side first.
