TruLayer
TruLayer gives AI engineering teams real-time tracing, eval-rule-backed failure detection, and a closed control loop that retries, gates on human approval, and rolls back automatically — turning every production failure into a system fix instead of an incident.

What it does
TruLayer is an AI reliability platform for teams shipping LLMs to production. Tracing — OTLP-native plus SDKs for OpenAI, Anthropic, LangChain, Vercel AI SDK, CrewAI, and 11 others. Evals — 25 LLM-judge evaluators inline: hallucination, faithfulness, tool-call correctness, PII, citation density. Control loop (new in v0.1) — eval fires → cluster → prompt diff → A/B → auto-ship → auto-rollback on regression. HITL gate at any step. Free tier: 1M spans/month, no card.
Evals score every output. A closed control loop retries with a fallback model, gates high-stakes actions on human approval, and rolls back automatically when a fix introduces a new regression — turning every production failure into a system fix before it hits the next user. Most tools stop at the trace. TruLayer takes you from “something’s wrong” to “here’s the fix, shipped” in one platform. Distributed traces, failure clustering, anomaly detection, and semantic search — everything you need to go from "something’s wrong" to "here’s exactly why." Configurable retry depth prevents runaway cascades: when a trace has been retried N times without passing eval, it escalates to the…from trulayer.ai

TracciaAug 2026 · traccia.ai · ▲197AI applications are becoming agents, which has started to take autonomous decisions. There are plenty of tools and platform available to trace, and observe what an agent or llms calls does. They are good in what they do, but tracing and observability isnt enough for AI agents era. We need a solution that can help you observe, evaluate, create run time policies to govern and finally audit the actions of the agent. We built Traccia to solve this problem. The good part, all of these can be achieved by just writing few lines of code. Traccia has an open-sourced sdk that can work with your…
Progress AI ObservabilityAug 2026 · telerik.com · ▲168Hi HN! We’re the team behind Fiddler, and we recently built an Agent Cache feature. It works by capturing an LLM request/response pair and, once caching is enabled, serving subsequent matching calls locally so duplicate requests never hit the provider. It’s meant to reduce three pains that show up together in agent development: token cost, feedback-loop latency, and output non-determinism. We’d love to hear your thoughts.
Kelet – Root Cause Analysis agent for your LLM appsApr 2026 · kelet.ai · ▲47I've spent the past few years building 50+ AI agents in prod (some reached 1M+ sessions/day), and the hardest part was never building them — it was figuring out why they fail. AI agents don't crash. They just quietly give wrong answers. You end up scrolling through traces one by one, trying to find a pattern across hundreds of sessions. Kelet automates that investigation. Here's how it works: 1. You connect your traces and signals (user feedback, edits, clicks, sentiment, LLM-as-a-judge, etc.) 2. Kelet processes those signals and extracts facts about each session 3. It forms hypotheses…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
