AI Agent Observability — Tools

  • Archal — Eval platform that tests AI agents against stateful sandboxed clones of GitHub, Slack, and Stripe before production. Free: 100 evals. YC S26.
  • Codag — Compresses 1.2M log lines to 3,300 tokens (8,021x) so AI agents diagnose incidents fast without burning token budgets.
  • Confident AI — LLM evaluation and tracing platform from the DeepEval team, with a free plan, CI regression tests and SOC 2 Type II.
  • Crukx — Enterprise LLM observability and optimization platform for engineering teams monitoring AI models and agents in production at observai.dev.
  • Kashikoi — Kashikoi is a no-code simulation platform for evaluating AI agents, built by the ex-Moveworks lead behind 250+ shipped enterprise agents.
  • Maitai — Maitai is a $50 to $200/mo control plane that indexes production LLM traffic and auto-corrects bad output in real time with Sentinels.
  • Openlayer — AI governance platform with an AI system inventory, 175+ evaluation tests and runtime guardrails that produce audit-ready evidence for regulators.
  • ReasonBlocks — YC-backed runtime that catches AI agent failures mid-run and, since a September 2026 site update, can turn recorded agent traffic into a smaller model the company markets as 3x cheaper at comparable accuracy.
  • SuperPenguin — AI spend platform with 2 native SDKs (Python, TypeScript) that attributes provider costs to a customer, feature, or pull request instead of one monthly total.
