Trends
Pyod
A Python library for anomaly detection across tabular, time series, graph, text, image, and audio data. 60+ detectors, benchmark-backed ADEngine orchestration, and an agentic workflow for AI agents.
Pricing: Open source under the BSD-2-Clause licence; check the website for any paid hosted plans.
Latest release 3.6.7:
- ABOD: cast non-float numeric input (integer lists and DataFrames, bool, float16) to float64 before the Numba angle kernel, which previously raised a TypingError. Scores for float32 and float64…
- XGBOD: keep estimatorlist and standardizationflaglist as given and store the resolved detectors in estimatorlist and standardizationflaglist, so getparams() and clone() round-trip. #767, fixes #755.
- Sampling and KPCA: store randomstate as given and resolve it in fit, so repeated fits with an integer seed are reproducible. #753, fixes #750.
- INNE: call BaseDetector.init, so an out-of-range contamination raises ValueError like every other detector. #759, fixes #752.
WrenAI
WrenAI gives AI agents a semantic layer and context layer over databases so they generate governed SQL and dashboards from natural-language questions. It ships as a CLI and MCP server for agents such as Claude Code and Cursor and connects to 22+ data sources.
Pricing: Open-source engine is free; Wren AI Cloud Free $0/month (20 monthly credits), Essential Cloud $179/month and Enterprise Cloud $559/month (billed annually); Enterprise Plus quoted by sales.
Latest release 0.3.1:
- sdk: read project artifacts as UTF-8 (#2764) (87b438a)
