Monocle is a pure OpenTelemetry instrumentation SDK with a companion test-assertion library. Everything the product does - the metamodel, the framework adapters, the test tools - ships in this Apache-2.0 repository, and there is no vendor selling a hosted or gated tier alongside it.

  Built under the Linux Foundation AI & Data umbrella. "This repository contains the Python implementation of Monocle's tracing SDK and metamodel", plus a separate monocle-test-tools package, with exports to local JSON files, console or an OTLP-compatible backend - no hosted service is described anywhere.

Adoption is measured by monthly PyPI downloads of monocle_apptrace, the SDK itself, since installing the package is installing Monocle and there is no separate platform behind it. GitHub stars on the project, which started in 2024, corroborate a still-growing community without adding to the reading.

Monocle is a standards-focused tracing and testing layer: broad framework coverage across LangChain, LlamaIndex, Haystack, Google ADK and more, plus a distinctive trace-assertion test tool, monocle-test-tools. It stops at instrumentation and testing, with no prompt management, evaluation, dataset or playground surface - the same shape as OpenLLMetry in this category and a step below Langfuse.

• https://raw.githubusercontent.com/monocle2ai/monocle/main/README.md recorded 2026-09-02

  Feature description: a metamodel for entities (agents, prompts, responses, tools, vector operations), instrumentation adapters for LangChain, LlamaIndex, Haystack, Google ADK, OpenAI and Anthropic, OTLP-compatible export, and a separate monocle-test-tools package for asserting on traces themselves - no evaluation, prompt-management or dataset section exists.
