Features and specs

What each product offers, as listed by its team.

Arize Phoenix 5 features
Telemetry.dev 3 features
  • Open source and free to self-host
    Phoenix is open source (Elastic License 2.0) and can be run locally, in a notebook, in Docker, or on Kubernetes at no licensing cost. This gives teams full control over their data and avoids vendor lock-in, which is useful for experimentation and privacy-sensitive workloads.
  • Built on OpenTelemetry and OpenInference
    Tracing is based on OpenTelemetry standards and the OpenInference instrumentation conventions. This makes it vendor- and framework-agnostic, with auto-instrumentation for LangChain, LlamaIndex, OpenAI, Anthropic, Bedrock, DSPy and others, and lets traces be exported to other OTel-compatible backends.
  • Comprehensive LLM observability and evaluation
    It combines tracing, LLM-based and code-based evaluations, datasets, experiments, prompt management and a playground in one tool. Teams can inspect spans, debug retrieval and agent workflows, run evals on traces, and compare experiments as they iterate on applications.
  • Easy local setup and notebook-friendly
    Phoenix can be launched with a simple pip install and a few lines of code, running locally or in Jupyter/Colab. This shortens the path from prototype to visibility into how an LLM app behaves, without requiring account creation or heavy infrastructure.
  • Clear upgrade path to Arize AX
    Because Phoenix shares concepts and instrumentation with Arize's commercial AX platform, teams can begin with the free tool and later move to a managed, enterprise-grade offering with more scale, monitoring and support without re-instrumenting their code.
  • Likely focus on developer telemetry
    I could not browse the site or verify its current features. Judging by the name and domain, it is probably aimed at developers who want to collect and view telemetry data such as usage, performance, or events. If so, it would suit teams that want insight into how their software behaves in production. Check the site to confirm.
  • Potential for fast setup
    Developer-focused telemetry tools usually offer SDKs or simple integrations that take little time to set up. I can't confirm that Telemetry.dev does. Check its documentation and quickstart guides.
  • Centralized visibility
    Tools in this category typically gather metrics, events, or logs in one place, which can speed up debugging and decision-making. Verify which data types Telemetry.dev supports.
