Aseprite vs Horizon EDA
A side-by-side editorial comparison of Aseprite and Horizon EDA — release velocity, themes, recent moves, and the top alternatives to consider.
Aseprite vs Horizon EDA: at a glance
What is Aseprite?
Aseprite v1.3.18 ships extension save formats and faster undo; patch cadence maintains stability
Aseprite is in stable post-1.3.18 maintenance, shipping crash fixes and platform-specific patches on a rapid cadence (three patch releases in two days). The 1.3.18 anchor release, shipped in late July, was the most substantive version in this window: faster undo/redo via in-memory object retention, full extension read/write format support, a Preferences search feature, and Lua API v40. The patch stream since then has been fixing regressions and long-standing platform-specific bugs rather than adding capability.
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.

Aseprite
5.0DESIGN
Aseprite v1.3.18 ships extension save formats and faster undo; patch cadence maintains stability
◆ Current state
Aseprite is in stable post-1.3.18 maintenance, shipping crash fixes and platform-specific patches on a rapid cadence (three patch releases in two days). The 1.3.18 anchor release, shipped in late July, was the most substantive version in this window: faster undo/redo via in-memory object retention, full extension read/write format support, a Preferences search feature, and Lua API v40. The patch stream since then has been fixing regressions and long-standing platform-specific bugs rather than adding capability.
◆ Where it's heading
The extension API expansion (custom file formats with save callbacks, not just read) started in 1.3.17.x betas and consolidated in 1.3.18, signaling a deliberate push toward a richer plugin ecosystem. The internal 'refactors needed for new layer types' PR merged in 1.3.18 suggests upcoming first-class layer type additions — the infrastructure is in place before any user-visible feature ships.
◆ Prediction
The next minor release will likely expose new layer types through the Lua API, building on the internal refactors already merged. The addition of .psd save support via extensions also sets up community-maintained format parity with tools like Photoshop that would previously require external converters.
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.
