## 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

## Kapsul

Kapsul approaches storage as a programmable layer rather than a fixed bucket of capacity. Users describe what a dataset needs — which fields must stay private, which jurisdictions apply, how many replicas are required, which reliability tier is acceptable — and the platform translates those constraints into storage behavior. Because the same control surface spans multiple cloud providers and self-hosted nodes, the intent is to avoid lock-in and keep data portable without rewriting how applications read and write it.

The blockchain component provides verifiable, immutable records of storage activity. That matters for teams that need to demonstrate to auditors, regulators or enterprise customers that data handling rules were actually enforced rather than merely documented. Compliance-oriented features are built in rather than bolted on, which makes Kapsul interesting for regulated industries and for Web3 applications that want durable off-chain data storage.

Kapsul is aimed at builders and platform teams dealing with sensitive or high-stakes data: healthcare records, media assets, financial workloads, supply-chain telemetry, and decentralized applications. The vendor offers a free trial plus demo-led onboarding, and publishes documentation for developers, which suggests a product rather than a purely experimental project. Prospective users should verify current pricing, region availability and supported cloud integrations directly with the vendor, since the platform evolves quickly.

**Pricing & Plans:** Kapsul advertises a free trial leading into paid plans, with custom pricing for teams and enterprises. Exact tiers and rates are not published on the homepage; a demo request is the documented path.

- **Programmable Storage Policies:** Define privacy, encryption, replication and reliability rules per dataset so storage behavior follows your specification instead of a provider's defaults.
- **Built-in Multi-Cloud Support:** Spread data across several cloud providers or self-hosted nodes from one control surface, reducing single-vendor dependency.
- **Adaptive Privacy and Security:** Tailor encryption and access strategies to each application's data sensitivity, keeping sensitive workloads isolated without separate tooling.
- **Compliance-Oriented Controls:** Regulatory requirements are modeled as first-class storage settings, helping teams document and enforce data-handling policy.
- **Verifiable, Immutable Records:** Blockchain-anchored logging gives tamper-evident proof of storage activity for audits and trust-sensitive use cases.

**Strengths:** Unifies privacy, compliance, reliability and multi-cloud control in a single platform; Blockchain-backed verification gives audit-friendly, tamper-evident storage records; Policy model is designed to be application-specific rather than one-size-fits-all; Positioned for regulated industries and AI-scale data volumes

**Limitations:** Public pricing is not listed, so budgeting requires a sales conversation; Homepage provides limited technical detail compared with a full developer reference; Decentralized storage adds architectural complexity that smaller teams may not need
