## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Instalog

Instalog is built around a single idea: production problems should be explained, not just recorded. Instead of dumping raw stack traces on you, it groups crashes, correlates them with logs, events, and device state, and then has AI describe the failing path in plain English. You can ask follow-up questions about millions of log lines in natural language and get answers that reference the real data, along with suggested patches tied to your actual code.

Integration is deliberately thin. One SDK package covers iOS, Android, Flutter, React Native, and Expo, and initialization is a single call at app start. After that, crashes, logs, and events flow automatically into one dashboard where sessions stream live and are grouped by event, so you can follow the sequence of user actions that led to a failure.

Beyond raw telemetry, Instalog folds in the human side of debugging: in-app feedback lets users report bugs with screenshots without leaving your app, AI code review inspects pull requests to flag problems before they ship, and Slack alerts and one-click Linear issues route findings straight into your team's existing workflow. The result is a shorter loop from first log line to shipped fix.

**Pricing & Plans:** Free plan at $0 forever for side projects and indie apps, including all SDKs, crash reporting, logs, and AI crash analysis. Team plan is $29 per developer per month with unlimited projects, AI code review, Slack and Linear integrations, and priority support. Enterprise pricing is custom with SSO/SAML and self-hosted deployment.

- **Crash reporting with device context:** Full stack traces paired with the device state that caused them, including OS version, device model, battery level, and build number.
- **Real-time logs and events:** Every session streams in live and is grouped by event, so you can reconstruct exactly what a user did before something went wrong.
- **AI crash analysis and suggested fixes:** Each crash group gets a plain-English explanation of the failing path, plus suggested patches that reference your actual code instead of generic advice.
- **Ask your logs in natural language:** Query millions of log lines in natural language and receive answers grounded in the underlying data rather than guesses.
- **In-app user feedback capture:** Users submit bugs with screenshots without leaving the app, and reports land in the same place as your technical telemetry.

**Strengths:** AI writes plain-English crash explanations instead of leaving you to parse stack traces; Single SDK spans mobile and cross-platform frameworks including Flutter, React Native, and Expo; Natural-language log querying makes large log volumes approachable for non-specialists; Free tier is genuinely usable, with AI crash analysis included at no cost

**Limitations:** Mobile-first focus means less depth for web backend or infra log pipelines; AI code review is behind the paid Team tier, not available on the free plan; Self-hosted and SSO options are limited to Enterprise contracts; Smaller ecosystem and fewer third-party integrations than legacy crash-reporting incumbents
