Spectragryph Alternative
A modern alternative to Spectragryph — no download, no license keys, works on any device
Spectragryph was one of the most widely used free spectroscopy tools available — relied on by thousands of researchers and widely cited in academic literature. It was the work of Dr. Friedrich Menges, who built and maintained it alongside his professional career for over a decade.
Dr. Menges' journey in spectroscopy software began with Spekwin32, which he developed from 2000 to 2016. He evolved it into Spectragryph in November 2016, and it became a go-to tool for the spectroscopy community.
Dr. Menges passed away in December 2024. His software is no longer maintained, and new license activations are no longer possible. SpectralBench was built to help fill the gap his absence created — ensuring that researchers and students continue to have a free, capable tool available to them.

SpectralBench is a free, browser-based spectroscopy tool designed for researchers, students, and analysts who need capable spectral analysis without cost barriers or platform restrictions.
Cross-platform access. SpectralBench runs in any modern browser — Mac, Linux, iPad, Chromebook, or Windows. Your spectra are accessible from any device, anywhere, with no installation required.
Modern analysis tools. AI-powered spectral interpretation that explains your peaks in plain language, a library of 54,825+ reference spectra for instant matching, PCA for multivariate analysis, and automated peak assignment across FTIR, Raman, and UV-Vis databases.
Collaboration built in. Share your spectrum with a colleague via a single link — no file attachments, no format compatibility issues. Contribute to the community reference library. Generate PDF reports for publications.
Active development. SpectralBench is under active development with regular feature releases and a growing reference library.
No download, no installation, no account. Just open your browser and go.
Drop your JCAMP-DX, SPC, CSV, or text file onto the viewer. Format is auto-detected.
Identify peaks, correct baselines, run PCA, match references, and export in any format.
SpectralBench supports 30+ spectral file formats from 16+ instrument vendors with intelligent auto-detection. If you have data from Spectragryph, export it as JCAMP-DX or CSV and open it directly.
SpectralBench is a free, browser-based spectroscopy tool that works on any platform — Windows, Mac, Linux, and iPad — without installation. It offers AI-powered spectral interpretation, a 54,825+ reference spectrum library, shareable links, a community library, PCA analysis, and advanced curve fitting.
SpectralBench supports JCAMP-DX (.dx, .jdx), SPC, CSV, and delimited text formats — the same formats Spectragryph can export to. If you have data saved in Spectragryph, export it to any of these formats and open it directly in SpectralBench.
Yes. SpectralBench runs entirely in your web browser — no installation or download required. It works on Windows, macOS, Linux, ChromeOS, and iPads. Unlike Spectragryph, which was Windows-only, SpectralBench is truly cross-platform.
Dr. Friedrich Menges, the sole developer of Spectragryph, passed away in December 2024. He dedicated over two decades to building free spectroscopy tools — first Spekwin32, then Spectragryph — serving thousands of researchers and students worldwide. The software is no longer maintained, and new license activations are no longer possible.
The Spectragryph download site remains online, but the software has not been updated since June 2022. Existing users with activated licenses can continue using it, but there will be no further updates or support.
Spekwin32 was Dr. Friedrich Menges' original spectroscopy software, developed from 2000 to 2016. He evolved it into Spectragryph in November 2016, which became widely adopted by researchers worldwide. Dr. Menges' passing in December 2024 left a gap in the community's free tooling. SpectralBench is an independent project built to help fill that gap — free, cross-platform, and actively developed. Users of either Spekwin32 or Spectragryph can export their data as JCAMP-DX or CSV and open it directly in SpectralBench.
Yes, SpectralBench is completely free for academic, research, and personal use. No account is required for core analysis features including file viewing, format conversion, peak identification, baseline correction, and curve fitting. No installation needed — it works in any browser.
