An independent workshop for open-source data tooling.

No SaaS. No seats. Just software you can read, run, and own - from visual data pipelines to file-format libraries.

Flagship

Loom

Visual data pipeline tool built on Polars. Self-hosted, no SaaS required. Approaching its first public release.

File formats

Reverse-engineering and documenting proprietary binary formats - open specs and clean-room readers for closed file types.

OpenYXDB

Maintained fork of Alteryx's YXDB library. Cross-platform C++ core with Python bindings via nanobind.

OpenQVD

Clean-room Rust reader/writer for Qlik QVD files. Full spec, Python bindings (PyArrow, Polars, Pandas), CLI.

OpenSQLAnywhere

Pure-Rust reader and open specification for SAP SQL Anywhere page-store files. CRC verification, slotted-page parsing, AP deobfuscation primitive.

OpenQBW

Pure-Rust reader for Intuit QuickBooks Desktop .QBW company files. Migrate to CSV, SQLite, or IIF without QuickBooks installed. Validated on 13,375 invoices, $399.9M total.

SigilYX

Standalone Rust reader and writer for Alteryx YXDB files, with Python bindings for Polars, PyArrow, and Pandas. Full E1 read/write; experimental E2 read.

Bioinformatics

GenoLance

Fast, columnar multi-sample variant store on LanceDB. Ingests VCF/BCF and ClinVar - query by region or gene, no Spark, no cloud.

OpenKSpace

Rust library and CLI for Cartesian MRI k-space reconstruction from ISMRMRD .h5 files.

DICOM Atlas

Open registry of public and private DICOM tags compiled from vendor conformance statements plus PS3.6, pydicom, and GDCM.

Mass Spectrometry

Clean-room specs and readers for closed mass-spectrometry formats, reverse-engineered without vendor SDKs.

OpenTFRaw

Pure-Rust parser for Thermo Fisher RAW files. Covers format versions 8-66, from the LCQ Classic through the Orbitrap Astral.

OpenTimsTDF

Pure-Rust parser for Bruker timsTOF TDF bundles. SQLite metadata + binary frames, both LZF and zstd codecs, full calibration.

OpenWRaw

Pure-Rust parser for Waters MassLynx RAW directories. Header, index, function inventory, externs, chromatograms, and frame data.

OpenARaw

Pure-Rust parser for Agilent MassHunter .d directories. Q-TOF and QQQ acquisitions, with centroid and profile signal.

OpenSXRaw

Pure-Rust parser for SCIEX .wiff / .wiff.scan legacy files. TripleTOF and QTRAP instrument families.

OpenMassSpec

Unified Rust and Python stack over all three parsers. Single API, mzML 1.1.0 conversion, Arrow output - no vendor SDKs.

OpenMassSpecCore

The canonical PSI-MS / Arrow vocabulary crate underlying OpenMassSpec. Lightweight, dependency-free, designed to be shared across the mass-spec ecosystem.

SpecLance

Columnar, memory-mapped mass-spec store built on Lance. Ingests via OpenMassSpec or mzML; query from Rust, Python, or the CLI.
