ForgePix

Overview

Four modules—Macro, Astro, Hybrid, and Long Exposure—organize ForgePix around different image-series workflows. Automatic mode selects usable frames, aligns and merges them, then applies gentle sharpening; users who want to steer a focus merge can choose among several methods instead. The result is a notably broad toolkit for a free desktop app, though the beta label is a reason to be cautious about relying on it for critical production work.

ForgePix says its processing works locally without AI, a server, or external astronomy software. Optional integrations extend that setup, but are not prerequisites for the core workflow. The interface is in German and English, and users can add languages by translating a language file.

Key features

Stacking and editing

Focus-merge choices include Laplacian pyramid, depth map, weighted average, à-trous wavelet, and halo fix. That range gives users alternatives to the one-click path when they want to choose a merging approach. Automatic alignment, RAW support, batch processing, and manual retouching are supported. A Camera-Raw editor and retouch brush handle edits, while a watch folder and export presets suit recurring jobs. Outputs include JPG, TIFF, layered Photoshop TIFF, and FITS.

Astrophotography and integrations

The Astro module brings calibration-frame detection, star alignment, rejection methods, drizzle, multi-session stacking, and FITS export into the app. That makes ForgePix relevant to astrophotographers who want stacking tools without requiring separate astronomy software for the stated workflow. Siril, GraXpert, StarNet++, and Cosmic Clarity are optional external tools.

Optional language-assistant connections work with OpenAI-compatible servers such as Ollama, llama.cpp, LM Studio, and vLLM, as well as OpenAI and OpenRouter. Assistant setup sends preview frames, a sharpness profile, basic EXIF data, and the user's request; it does not send original files or location data. Local AI image models are experimental, are not enabled automatically, and may change faint structures, flux, or star shapes. Those caveats matter especially for astrophotography, where preserving subtle structures can be important.

Pricing

ForgePix is free: the Free (MIT) plan costs 0.00 USD per free and is distributed under the MIT license. It is not a time-limited trial. The published plan is the app itself, with no paid tier or seat or usage quota to weigh against the price. Its main trade-off is not a cheaper feature-restricted plan, but beta status: v1.28.0-beta is marked as a prerelease and not a release candidate.

Platforms

Prebuilt desktop downloads are listed for Linux, macOS, and Windows. ForgePix is therefore an option across the three major desktop platforms, but not a mobile app. The MIT license is relevant to users who want software they can use under that license.

Who it's for

Choose ForgePix if you need focus stacking or astrophotography tools alongside editing and batch workflows, and prefer a free app whose core processing stays local. It is particularly compelling for users who value the Astro module's calibration, alignment, and multi-session tools or want several focus-merge methods in one desktop package.

Look elsewhere if beta software is unsuitable for your workflow, if you need a mobile version, or if experimental AI image processing must preserve faint detail without risk of alteration. The optional assistant also sends preview and related data, so users unwilling to share those items should leave that integration out of their workflow.

Pros and cons

• Pros: Macro, Astro, Hybrid, and Long Exposure modules bring several image-series workflows together.
• Pros: Multiple focus-merge methods, RAW support, retouching, batch processing, and a watch folder cover both merging and follow-up work.
• Pros: Core processing is described as local and does not require AI, a server, or external astronomy software.
• Pros: The app is free under the MIT license, with prebuilt downloads for Linux, macOS, and Windows.
• Cons: It is a beta prerelease, not a release candidate, which makes it a less reassuring choice for workflows that demand release stability.
• Cons: Experimental local AI image models can alter faint structures, flux, or star shapes, a material risk for detail-sensitive astrophotography.
• Cons: Assistant connections send preview frames, sharpness profile, basic EXIF data, and the user's request, which may not suit every privacy preference.

Alternatives

Browse focus-stacking software for a broader set of options. Consider ImageFocus Alpha if you need a free option that also runs on Android and iOS, or if you use compatible Euromex camera models, for which it is designed. PlaneFuse is another free, MIT-licensed choice for personal or commercial use, with web, API, and self-hosted options alongside desktop platforms. Choose Shine Stacker if you want a free download described by its maker as open source under LGPL-3.0. Aduku Stacker is another free option for macOS and Windows. PICOLAY is free for non-commercial use on Windows and is offered as is without warranty. ChimpStackr, CKAN, and Enfuse are also alternatives for Windows, macOS, and Linux.

Verdict

ForgePix is an easy recommendation for photographers who want a free, local desktop toolkit spanning focus stacking, astrophotography, and image editing. Its strongest reason to choose is the breadth of those workflows in one app; its clearest reason to look elsewhere is beta status, especially if release stability matters more than the feature range.
