WhyLabs was an AI observability platform for monitoring ML models, LLM apps, and data pipelines. WhyLabs, Inc. has discontinued operations; docs say the AI Control Center became Apache-2.0 OSS on January 23, 2025 and hosted SaaS access ended March 9, 2025. The whylogs, LangKit, and whylabs-oss repos remain public, so this page is a self-hosted OSS handoff, not an active managed SaaS recommendation.

WhyLabs was an AI observability platform created at the Allen Institute for Artificial Intelligence (AI2) by Amazon Machine Learning alumni. WhyLabs, Inc. has discontinued operations, and the AI Control Center became an open-source project on January 23, 2025. Hosted SaaS access for existing customers was available until March 9, 2025, so this page now reflects the self-hosted OSS handoff rather than an active managed SaaS.

The platform monitors ML models, LLM applications, and data pipelines, surfacing data drift, quality issues, performance degradation, and bias. Automated alerting across dozens of data vitals comes with out-of-the-box configurations. Purpose-built agents analyze raw data without moving or duplicating it, ensuring privacy and security.

For LLM applications, WhyLabs extracts telemetry from prompts and responses to detect malicious prompts, toxicity, hallucinations, and jailbreak attempts. The system processes 100% of data without sampling, supporting tabular, image, text, and embedding data types across any platform.

The OSS handoff centers on the whylabs-oss platform plus whylogs for privacy-preserving data logging and LangKit for LLM monitoring. The repositories remain public under Apache-2.0, but WhyLabs docs say the AI Control Center OSS project is not accepting community contributions or new feature requests from the former team.

Historical integrations included Azure, SageMaker, MLflow, Apache Spark, Pandas, Kafka, Ray, Airflow, dbt, and Databricks. Teams evaluating the code now should plan for self-hosting, Highcharts licensing where dashboards require it, and their own maintenance path.

Pricing

Hosted SaaS ended March 9, 2025; AI Control Center is Apache-2.0 self-hosted OSS.

Self-hosted OSS; hosted SaaS discontinued

Why it died

WhyLabs, Inc. has discontinued operations. Official WhyLabs docs say the AI Control Center became an Apache-2.0 open-source project on January 23, 2025 and hosted SaaS access for existing customers remained available only until March 9, 2025. Keep this page as a historical/self-hosted OSS handoff for whylabs-oss, whylogs, and LangKit rather than as a current managed-SaaS buying recommendation.

Session reports for Claude Code and Codex runs

Spotlight by Backplanes turns completed Claude Code and Codex sessions into concise reports for engineering, security, and spend review. The CLI installs on macOS, Linux, or WSL 2, watches sessions after they finish, redacts PII and credentials locally before upload, then summarizes files touched, commands run, external domains reached, scope drift, risky actions, and next-session improvements.
