SpectraFox is a free and open-source desktop application for scanning probe microscopy data. It is mainly designed for managing, processing, and evaluating data files generated by STM, STS, AFM, and related experiments. Rather than being a general-purpose developer tool, it is a scientific data analysis application suited to surface science, materials science, and nanoscale characterization workflows.
In terms of functionality, SpectraFox covers data browsing, quick preview, spectrum and scan image visualization, batch processing, mathematical transformations, and specialized data processing. It supports adding and multiplying scalar or reference data, normalization, nonlinear single- and multi-function fitting, smoothing, averaging across files, data rescaling, as well as advanced features such as force and instantaneous current deconvolution in frequency-modulation AFM. A major advantage is that operations can be applied to multiple files at once, while the original data is never modified, reducing the risk of mistakes in scientific data processing.
The software explicitly supports Windows Vista and later, and depends on the .NET Framework. In terms of file formats, it supports data from instruments or systems such as SPECS, Nanonis, Createc STMAFM, Omicron Matrix, Nanotec Electronica WSxM, and Bruker AFM, including both spectra and scan images. For export, it supports CSV, Origin-compatible files, and Mathematica notebooks, making it easier to move into paper figure preparation and numerical analysis workflows. The website also lists third-party libraries such as Math.NET Numerics, Json.NET, and ZedGraph, but does not provide API/SDK information.
SpectraFox is free to use and is open source under the GNU LGPL v3 license, allowing use, distribution, and modification. If the software contributes to scientific work, the official recommendation is to cite its SoftwareX paper. This model is very friendly to university labs and research teams with limited budgets.
Its strengths are a clear focus on professional research scenarios, strong batch-processing capabilities, broad format compatibility, practical export options, and the fact that it is free and open source. Its limitations are that only Windows support is mentioned, and there is no visible information about commercial support, SLA, cloud collaboration, or plugin/API capabilities; it also has limited value for users outside the SPM field. It is best suited to researchers who regularly process STM/STS/AFM data, rather than general software development teams.
The captured text does not provide information about access from mainland China, mirrors, or payment. Since the software is free and can be installed locally, payment is not a major barrier. If access to the website or Git repository is unstable, alternatives such as Gwyddion, WSxM, instrument vendor software, Origin, or Mathematica may be worth considering.
