## Raindrop

Agents fail differently from normal software. A run can complete without any exception while still producing the wrong answer, calling the wrong tool, or looping on a failed retry. Raindrop is designed around that reality: it records each message, tool call and decision as a trace, then looks for patterns across many runs so a recurring problem becomes a single, trackable issue with severity, affected user counts and confidence.

The workflow moves from signal to fix. Teams trace an individual run to see exactly where things went wrong, use the triage agent to investigate and automate work in Slack, the web app or via MCP, and then run simulations on a pull request to see what a change would do before merging. A comparison view checks the change against real traffic so you can confirm which behaviours improved rather than guessing. A local Workshop tool lets engineers inspect, replay and debug agents on their own machines.

Raindrop covers both monitoring and pre-release testing, which makes it useful for teams shipping agents to large audiences — the site notes customers running agents used by millions of users. Because the space moves quickly, feature names and packaging may change; check the site and docs for the current scope, and note that the company has raised a $50m Series A, a signal of continued investment.

**Pricing & Plans:** Raindrop offers a free starting tier with no credit card required for individual developers and small teams, plus paid plans for larger usage, an enterprise option, and a free programme for teams building agents for social good. Exact seat and usage pricing is on the pricing page and can change, so confirm there before committing.

- **Agent tracing:** See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
- **Automatic issue detection:** Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
- **Triage agent and integrations:** An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
- **Simulations in CI:** Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.
- **Local Workshop debugger:** Inspect, replay and debug agent behaviour locally without round-tripping through production.

**Strengths:** Purpose-built for agent traces and non-throwing failures, not generic APM; Covers the full loop from detection to investigation to simulation; Triage agent works inside Slack, web and MCP where teams already operate; Free starting tier and no credit card required to begin

**Limitations:** Aimed at teams already running agents in production, which is a narrowing audience; Advanced simulation and enterprise capabilities sit behind paid and enterprise plans; Fast-moving product surface means some features may shift or be labelled beta

## Voker

Voker is an analytics platform built specifically for AI agents. As agents move from demos into production, teams run into a familiar problem: it is easy to see that something went wrong, but hard to understand why. Voker instruments LLM calls so you can observe agent behavior at the level that matters — individual sessions, recurring intents and the overall performance of each agent you ship.

Integration is designed to be minimal. Voker ships SDKs for JavaScript/TypeScript (@voker/voker) and Python (voker) that wrap existing provider clients. In most cases you change an import — for example, swapping the OpenAI client for the Voker-wrapped OpenAI provider — and then pass vokerAgent and vokerSession parameters to your LLM calls. Agents are named so they can be tracked separately, and sessions are unique per conversation, giving Voker the structure it needs to analyze behavior. Providers with explicit wrapping support include OpenAI, Anthropic, Gemini and the Vercel AI SDK, and anything else can report through the REST API or the base SDK.

Beyond tracing, Voker is oriented toward improvement. Intent detection shows what users actually ask agents and how well those requests are served — a direct input to prompt engineering and product decisions. The site also emphasizes a frictionless onboarding path, including a setup prompt you can paste into an AI coding assistant so the SDK, API key and first event are configured automatically, typically in a couple of minutes. Voker is aimed at developers and teams running conversational AI in production who want self-service analytics rather than a heavyweight enterprise observability deployment.

**Pricing & Plans:** Voker offers a free tier alongside paid plans, with a free trial available and contact options for larger or custom requirements; see the site's pricing page for current figures.

- **SDK wrapping for LLM providers:** Wrap your existing OpenAI, Anthropic, Gemini or Vercel AI SDK client and every call is instrumented automatically with agent and session context.
- **Agent and session tracking:** Voker organizes activity by agent and by session, so you can follow a single conversation end to end and see how it developed.
- **Intent detection and analysis:** Understand which intents users bring to your agent and how well the agent handles them, revealing where prompts or flows need work.
- **Custom event instrumentation:** If you need more control, create custom events through the SDK or REST API to capture exactly the behavior you care about.
- **AI-assisted setup:** A guided setup prompt can be pasted into your AI coding tool to scaffold the SDK, add your API key and instrument a first event in about two minutes.

**Strengths:** Purpose-built for agent and conversation analytics rather than generic logging; Minimal integration — often just swapping an import and adding two parameters; Supports the major providers (OpenAI, Anthropic, Gemini, Vercel AI SDK) in JS/TS and Python; Intent detection turns raw traces into actionable improvement signals

**Limitations:** Requires code changes — you must swap SDK imports and pass agent/session parameters; Value depends on teams already running agents in production with volume worth analyzing; SDK depth is strongest for OpenAI, Anthropic, Gemini and Vercel AI SDK rather than every framework; Niche focus means it complements rather than replaces a broad APM suite
