Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
Skills-based hiring platform for technical interviews, assessments and live coding
A multi-file IDE with whiteboard, structured scoring, private notes and code playback so interviewers can assess real problem solving rather than puzzle recall.
Automated pre-screens built from practical engineering tasks, with clear scoring that helps recruiters move qualified candidates forward faster.
AI assistants work with code context, prompts are captured, and AI reviewers rank video or code submissions against your own rubric.
Adaptive tests, activity monitoring, real-time alerts and playback reports help detect suspicious behaviour without manual review.
