Agent Prism
Open-source React components for rendering AI agent traces, tool calls and reasoning inside your own app.
For a React developer who wants agent trace visualization living inside their own product, Agent Prism is the shortest path: TraceViewer, SpanCard and DetailsView with Thinking and Todos tabs do the span-tree work that charting libraries leave to you. Treat it as a rendering layer, not an observability platform — storage, filtering and alerting stay yours. If you need dashboards, retention or SSO on trace data out of the box, buy a platform instead.

Skip Agent Prism if you want to buy an observability service with hosted dashboards, retention and access control rather than assemble a viewer inside your own React app.
The library is free, but you absorb the engineering cost of storing, filtering and retaining traces yourself — that pipeline is the real line item.
Agent Prism is open-source and free to embed, which puts it in a different budget conversation from hosted agent observability platforms that charge per seat or per ingested trace. The cost you compare isn't licence fee versus licence fee — it's zero licence plus your own storage and engineering time versus a platform subscription that bundles retention, dashboards and access control.
In short

Free to use.
What is Agent Prism?
Agent Prism — Open-source React components for rendering AI agent traces, tool calls and reasoning inside your own app. Best for React and TypeScript developers building agentic workflows, Teams that want trace visualization without sending logs to a SaaS vendor, Product teams adding AI transparency inside an existing React UI. Free to use.
Agent Prism is an open-source React component library for visualizing AI agent traces and reasoning inside your own application. Rather than exporting logs to a hosted observability platform, you import the pieces and render structured traces yourself. The Storybook reference lists five main components — TraceViewer, TraceList, TreeView, SpanCard and DetailsView — plus atoms including SpanBadge, TokensBadge, ThinkingBadge, TimestampBadge, PriceBadge, ErrorCountBadge and ErrorStatusCircle, along with SearchInput and Tabs for narrowing noisy runs. DetailsView carries its own Context and Thinking tabs and a Todos section, so one span can be inspected for what the model saw, what it reasoned, and what it planned. Components are built around span trees and tool-call chains instead of generic log lines — the assembly work charting libraries leave to you. Per the project's own positioning, trace data never leaves your app: you supply storage, filtering and alerting; Agent Prism supplies the rendering layer. It targets React and TypeScript developers building agentic workflows who need to see which tools fired, in what order, and what each returned — and who would rather ship that view inside an existing design system than send production traces to a third party. The trade is deliberate. You get full control of rendering and styling and take on the data pipeline behind it. Against hosted trace viewers such as LangSmith or Arize, Agent Prism is the embeddable rendering layer, not the platform.
Key features
- TraceViewer component for rendering a full agent trace
- TraceList component for browsing multiple runs
- TreeView component for span hierarchies
- SpanCard with status and token badges
- Status and timestamp badges on span cards
- PriceBadge atom for per-span cost display
- DetailsView component with Context, Thinking and Todos tabs
- Thinking tab for inspecting an agent's reasoning on a span
- Context tab showing what the model received for a span
- Todos section for planned steps within a span
- Tool-call and tool-result display on spans
- ThinkingBadge and TokensBadge atoms
- ErrorCountBadge and ErrorStatusCircle for failure states
- SearchInput for filtering traces
- Tabs and CollapsibleSection for nested span detail
Behind the verdict
Pick Agent Prism when the trace view is supposed to be part of your product, not a separate tab you bookmark. If your spans already land in your own store and you want them drawn inside an existing React design system, the component set maps closely to that job. The strongest argument is the span-level detail. DetailsView splits Context, Thinking and Todos into tabs, so a reviewer can see what the model received, what it reasoned, and what it planned without leaving the run. ErrorCountBadge and ErrorStatusCircle surface failure states at a glance, and SearchInput plus the collapsible sections keep long runs readable. Where it bites: this is a rendering layer. Retention policies, alerting, filtering on the backend and multi-user access control are all yours to build. Teams expecting a managed service will spend the first week on plumbing. Compared with a hosted platform like LangSmith or Arize, the split is clean. They sell you the pipeline and the dashboard; Agent Prism sells you nothing and gives you the view. If trace data must stay in your app, that difference decides it. In practice, budget for styling work — the atoms help, but matching your design system is on you. Start with TraceViewer plus SpanCard for a single run, add TreeView once span hierarchies get deep.
Limitations
- Agent Prism is a rendering layer, so it ships no storage, retention, alerting or access control — you supply the trace pipeline behind the components.
- It is open-source software in early development, and the public reference is a Storybook component playground rather than a guide to running it in production, so plan to read the source and pin versions.
- Its value depends on your traces already being structured into spans before they reach the components.
- Budget engineering time for the parts it deliberately leaves out.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Agent Prism actually fits — and what changes day-one when you adopt it.
You already emit structured spans from your agent runtime into your own store. You import TraceViewer and TreeView, feed it a run, and click into the failing span to read its status, token count and tool result.
Outcome: You find which tool call returned bad data without leaving your app or exporting logs to a third party.
You want customers to see what your assistant did on their behalf. You render a trimmed TraceList of tool calls and timestamps in the customer dashboard, styled to your design system.
Outcome: The AI feature gains a visible audit trail, and you control exactly which spans are exposed.
A run takes an odd path. You open DetailsView on the suspect span and compare its Context tab with its Thinking tab and Todos section.
Outcome: You see whether the model was given the wrong input or reasoned correctly from bad context, and fix the right layer.
Use cases
- Render agent reasoning traces inside a React debugging dashboard
- Show a multi-step tool-calling chain in an AI assistant's admin view
- Add step-by-step transparency to a user-facing AI feature
- Inspect span context and thinking to refine agent prompts
- Present agent capabilities in demos and documentation
- Give support engineers a read-only trace view for customer escalations
Setup time & first value
How long it actually takes to get something useful out of Agent Prism — broken out by persona, not the marketing-page minute.
For a React developer with traces already flowing: under an hour to render your first TraceViewer by importing the components and mapping your span shape. Add half a day for styling into an existing design system. Teams that have not yet built trace capture and storage should budget that work first — it dominates the timeline.
Switching to or from Agent Prism
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a custom in-house trace UI: replace bespoke span cards and tree rendering with SpanCard and TreeView against the same span data.
- →From a hosted observability dashboard: keep your existing trace storage and point TraceViewer at it for in-product rendering while the platform remains for ops.
- ↗To LangSmith or Arize: keep the span schema you built and forward the same traces to a managed platform for retention, dashboards and alerting.
