calibrate-pro, the most finished of them.
A professional display-calibration suite for Windows, with both a graphical interface and a command line. It detects your monitors, matches the panel against a database, and applies real corrections through the hardware: DDC/CI control (sending commands directly to the monitor over a standard cable) and 3D-LUT output (a color-correction table loaded into the display), ICC v4 profiles, HDR-aware. It has a sensorless mode that predicts a good profile from a database of 58 characterized panels (predicted ΔE under 1.0), and a native i1Display3 driver that talks to the colorimeter directly over USB, no third-party color stack required. This is the genuinely shippable one: 297 tests, ~26 working CLI subcommands, and a standalone .exe so you don’t need Python at all.
The forecasting & trading toolkits, paper-first by design.
build-oracle is a toolkit for predicting trends in data over time and spotting unusual breaks or jumps: ARIMA with automatic order selection, structural-break (changepoint) detection by information criterion (a score that picks the simplest explanation that still fits the data), and feature engineering, which builds extra signals like recent averages, lag values, and Fourier terms to help the model see patterns. 187 tests. The honest forecasting layer the others build on.
build-finance is a rule-based trading toolkit for stocks and crypto: backtesting (running a strategy against old data to see what would have happened), portfolio optimization using named methods (Markowitz, Black–Litterman, Hierarchical Risk Parity, Risk Parity), and strategies like an EMA-crossover momentum filter. 142 tests. It runs the analysis and the backtest; it doesn’t pretend a backtest is a promise.
build-engine is the self-adjusting loop on top: it trains forecasters, turns forecasts into signals, paper-trades or backtests them, and feeds the results back to adjust its own internal settings (the numbers that determine how the model behaves). 178 tests. It is paper-trading by default, and live brokerage is deliberately hard to switch on. It refuses to run live unless you set an explicit risk-acknowledgement in the environment. The guardrail is the feature.
These are real toolkits, honestly beta. Nothing here is financial advice, and the design assumes you’ll paper-trade first; it makes that the path of least resistance on purpose.The suite, and one tool reporting itself.
build-ui is the shared visual style and controls (a PyQt6 theme and widget set) the GUI apps are built from, so the suite looks like one thing. build-ecosystem is the single package that installs the whole set in one command, and build-color is the color-science member, with its own page. Here is the most mature member confirming what it is.
$ python -m calibrate_pro --version Calibrate Pro v1.0.0 $ python -m calibrate_pro --help Calibrate Pro - Professional Display Calibration Suite positional arguments: {detect, calibrate, verify, list-panels, list-targets, match, refine, ddc-calibrate, ddc-info, native-calibrate, hdr, uniformity, export-panel, import-panel, generate-profiles, gui, status, ...} detect Detect connected displays native-calibrate Calibrate using the native i1Display3 driver (no ArgyllCMS) ddc-info Show DDC/CI capabilities for connected monitors verify Verify calibration accuracy
The breadth is real: detection, hardware DDC/CI control, a native colorimeter driver, verification reports. Not a wrapper around someone else’s tool; the driver and the panel database are the work.
Real output from calibrate-pro v1.0.0 (297 tests). Suite test counts: calibrate-pro 297 · build-oracle 187 · build-engine 178 · build-finance 142 · build-ui 17 · build-ecosystem 10. Honest limit: every member is marked beta and is currently installed from source (calibrate-pro also ships a standalone Windows build); they are packaged for a public index but not published to one yet, so I won’t claim “available on PyPI.” calibrate-pro is the one I’d call genuinely product-grade today; the quant tools are substantive but still beta.
Where they really are.
These are real, tested software you can use today, a product line that also funds the slower accountability and language work and gives it somewhere practical to land. calibrate-pro is the most finished, a tool I’d hand to a colorist today. build-oracle, build-finance, and build-engine are substantive beta toolkits with named, tested methods, built paper-first with their risk gates on by default. build-ui and build-ecosystem are exactly what they sound like, the shared look and the one-command installer: small glue, not headline products.
Tested and usable, honestly beta, and not on a package index yet. I’d rather you know that than find out.
