Active failure detection · not just observability

Your AI agent is breaking.
You just don't see it.

Dottle detects failures, explains why they happen, and helps you fix them before your users complain.

No dashboards to configure. We set everything up for you.

The problem

Agents fail silently.

01

Infinite loops draining tokens

Your agent retries forever. No exit condition, no backoff. 43 tool calls, $12 wasted. You find out from your invoice.

02

Tool failures without visibility

A tool call fails silently. Your agent continues with an empty result. The user gets a broken experience and you never know.

03

Wrong outputs reaching users

No output validation. The agent returns a hallucinated or off-topic response. It's logged as a success. Nobody catches it.

04

No clear root cause

All three runs failed. You dig through logs for hours. Every error says 'exit code 1'. Nothing tells you why.

The solution

We don't just show logs.
We tell you what broke.

Other tools give you observability — a passive stream of data you still have to interpret. Dottle does the analysis for you.

Detect failures automatically

Loops, tool errors, bad outputs — caught the moment they happen. No manual thresholds or configs.

Trace every agent run

Every step, tool call, and LLM decision captured end-to-end. Full timeline, not just error lines.

Highlight exactly where it failed

Not 'something broke at step 4.' The exact call, input, and response — isolated and explained.

Suggest the root cause

Pattern-matched diagnosis across thousands of agent runs. We tell you why and how to fix it.

Set up in under an hour.

Monitoring from day one. No dedicated team required.

01

Connect your agent

SDK or webhook — works with any framework. Minimal code change, no infrastructure to manage.

< 30 min setup
02

We monitor every run

Every step, token, tool call, and LLM response is captured in real-time, automatically.

Zero config
03

Get instant failure alerts

When something breaks we flag it, explain it, and send you the root cause via Slack or webhook.

Alert in < 10s

Not another observability tool.

Langfuse, LangSmith, and Datadog show you data. Dottle tells you what went wrong and why.

Built for teams running AI agents
in production.

Not for researchers. Not for hobby projects.

Startups using LangChain or custom agents

You move fast and can't afford production failures killing your demo or your users' trust.

Teams with agents serving real users

Your agent is customer-facing. A broken run isn't just an error — it's a bad user experience.

Engineers tired of debugging blindly

You've spent hours in logs with no answers. Dottle tells you what broke in seconds.

Stop guessing why your agent failed.
