Kayba
Kayba
Kayba makes AI agents self-improve from experience. It learns from an agent’s execution traces to detect failures, fix them, and measure whether the fix actually worked. Instead of relying on generic evals that cannot explain why an agent failed, Kayba derives failure modes from the agent’s own traces and builds custom benchmarks for the user’s domain, so teams can measure improvement against real production failure patterns. Kayba wires tracing into an agent with one line of setup, watches it around the clock, and flags the moment a step stops being recorded. Even good tracing rots as teams ship changes, and steps can quietly stop being captured; Kayba checks the tracing users already have, shows exactly what is broken, points to the file that needs attention, and sends the gap to a coding agent through MCP. The coding agent patches the issue, and Kayba verifies that the trace is actually closed.Starting Price: Free -

Papaya
Papaya
Papaya is the optimization engine for AI agents. Engineers connect their agents via SDK, and Papaya analyzes production traces to find improvements across context, prompts, prompt caching, subagents, and tool calls. It delivers actionable recommendations ranked by quality, latency, and cost impact, with the production runs that produced each finding. Approved improvements can be pushed to production as pull requests. Papaya runs more than 200 research-backed analyses and typically finds a 10%+ quality improvement on the first workflow analysis.Starting Price: Free -

LangSmith
LangChain
Unexpected results happen all the time. With full visibility into the entire chain sequence of calls, you can spot the source of errors and surprises in real time with surgical precision. Software engineering relies on unit testing to build performant, production-ready applications. LangSmith provides that same functionality for LLM applications. Spin up test datasets, run your applications over them, and inspect results without having to leave LangSmith. LangSmith enables mission-critical observability with only a few lines of code. LangSmith is designed to help developers harness the power–and wrangle the complexity–of LLMs. We’re not only building tools. We’re establishing best practices you can rely on. Build and deploy LLM applications with confidence. Application-level usage stats. Feedback collection. Filter traces, cost and performance measurement. Dataset curation, compare chain performance, AI-assisted evaluation, and embrace best practices. -

Galileo
Cisco
Galileo is an AI observability and eval engineering platform that helps teams measure, protect, and improve AI systems in development and production. Now part of Cisco, the platform turns offline evaluations into production guardrails so teams can stop AI failures instead of only monitoring them. Galileo helps users build datasets from synthetic, development, and live production data, while capturing subject matter expert annotations as ground truth. The platform includes more than 20 out-of-the-box evals for RAG, agents, safety, security, and custom evaluation workflows. Its Luna models distill expensive LLM-as-judge evaluators into lower-cost, low-latency guardrails that can monitor production traffic. Built for enterprises and developers, Galileo helps teams debug failures, improve agent behavior, enforce AI policies, and ship AI applications with more confidence. -

Sawmills
Sawmills.ai
Sawmills is the first smart telemetry management platform, giving enterprises control over telemetry data before it reaches costly observability tools. No other solution in the market applies AI-based detection for noise to telemetry optimization, making Sawmills uniquely positioned to cut waste, improve data quality, and enforce governance. Traditional filtering and hand-written rules don’t scale. Sawmills applies AI to your telemetry pipeline to continuously detect noise patterns, duplicate and near-duplicate events, low-value attributes, cardinality explosions, PII/policy violations, and broken schemas. For each finding, Sawmills proposes an action: filter, redact, aggregate, downsample, normalize, enrich, and can auto-remediate with approvals, SLAs, and rollbacks. This shifts control upstream, reduces waste, improves data quality, and makes governance automatic.Starting Price: $0 -
