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 Blocks Pro 1.0.6 fixes dynamic data and Loop Builder on the front end.
Spectra Blocks Pro 1.0.6 is a fix release that makes dynamic content in templates, query loops and sliders behave reliably on the live site. It follows free-plugin 1.0.12, which fixed per-card featured images in Post blocks and added shortcode Button labels in full-site editing.

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 1.0.6 fixes dynamic data and Loop Builder on the front end.
◆ Current state
Spectra Blocks Pro 1.0.6 is a fix release that makes dynamic content in templates, query loops and sliders behave reliably on the live site. It follows free-plugin 1.0.12, which fixed per-card featured images in Post blocks and added shortcode Button labels in full-site editing.
◆ Where it's heading
Spectra's last several releases have focused on matching the editor preview to the live site, first for AI-imported pages and containers, now for dynamic data and loops. The Pro add-on is filling in reliability after its style-guide and white-label features.
◆ Prediction
Expect more fidelity patches on both plugins; the entries don't point to a new feature release yet.
