# The LLMOps Stack 2026 — OpenTelemetry, self-host & pricing models

First-party research dataset from the **Lattice network**, published open under CC-BY 4.0 with a
permanent DOI. Nothing here is scraped from another dataset — it is computed and published under a
single ORCID-verified byline.

## What it is

A structured comparison of 19 production LLM-operations tools across four stack layers (gateway/routing, observability/tracing, evaluation/testing, guardrails/safety) on five interoperability and cost dimensions: OpenTelemetry-native support, self-host availability, open-source licensing, pricing model, and whether evaluation and guardrails are built in. Compiled vendor-neutral with conflict disclosure; each cell read from the tool's own documentation, repository, or pricing page. Methodology and full sourcing at https://nesyona.com/research/llmops-stack-comparison-2026/ . License CC-BY 4.0.
