H2O Driverless AI vs Vizly

H2O Driverless AI automates machine-learning work from feature engineering and model building through validation, tuning, selection, visualization, interpretability, and scoring-pipeline generation. It explains model output at both global and individual-prediction levels. Models can be deployed as REST endpoints, cloud services, or optimized Java code for edge devices. Supported hardware includes NVIDIA GPUs, IBM Power 9, and Intel x86 CPUs; GPU-accelerated algorithms include XGBoost, TensorFlow, and LightGBM. Documented integrations include Kubernetes, Kubeflow, SageMaker, Alteryx, Jupyter/Python, KDB, Qlik, Trifacta, and UiPath. Data sources include HDFS, Amazon S3, Azure Blob Storage, Google BigQuery, Google Cloud Storage, Snowflake, JDBC, Databricks, and Delta Table. Cloud installation options are H2O AI Cloud, AWS, Azure, and Google Cloud. H2O offers a 21-day public-cloud evaluation license and a guided two-hour cloud test drive. Commercial licensing requires contacting sales; no price is listed. The default installation disables security, so production use calls for secure installation.

Vizly is a web-based conversational data analyst that turns natural-language questions into charts, explanations, and insights. It translates questions into Python or R code for analyzing uploaded data, then creates interactive bar, pie, line, Sankey, and scatter visualizations. The service says it supports all file types and specifically highlights CSV, Excel, SPSS, PDF, image, and JSON files; Google Sheets is also listed as a use case. Users can generate reports, share them by link, export reports to Word or PDF, and export analyzed or transformed data as CSV or Excel. Uploaded files are encrypted in transit and at rest and kept in an isolated environment accessible only to the user, according to Vizly. Files are removed after one hour of inactivity, while Premium users can choose longer retention. The Free plan allows up to 0 messages per month. Basic costs $19.99 a month for up to 200 messages; Premium costs $29.99 a month with unlimited messages, persistent files, and priority support.
