For teams who need to know what their agents actually decided
Your agent ran.Did it work?
Logs show execution. Traces show decisions - every tool called, every choice made, exactly where it went wrong.
Free tier · Works with LangChain, AutoGen, LlamaIndex, CrewAI, and custom agents
Building in production with teams like these
Traces, not just logs.
You see "agent ran." You have no idea what it decided.
Every LLM call, tool use, and memory read captured with full input/output context.
Root cause takes hours of log archaeology.
Root cause identified in plain English, in under 2 minutes.
Framework-specific logs are partial and incomplete.
Single unified trace across LangChain, AutoGen, CrewAI, and custom agents.
You find out from a customer complaint, 72 hours later.
Silent failures surface before your users notice them.
No credit card required · Free tier · Setup in 2 minutes
The agent returns a result. Just the wrong one. Your logs show a 200. Your customer sees garbage. You find out three days later.
Running isn't the same as working.
Logs show execution, not reasoning
You can see that your agent ran. You cannot see the chain of decisions that led to the wrong output. There is a difference between "it ran" and "it worked."
72-hour failure windows
The average team discovers agent logic failures 3 days after they start, in production, after real damage. By then, the context is cold and the trail is gone.
Framework traces are incomplete
LangChain gives you partial visibility. AutoGen gives you logs. Neither gives you the full picture of what actually happened inside a multi-agent pipeline.
“You're running the most complex software you've ever shipped, with less visibility than a 2015 REST API.”
Your agents are making decisions you cannot see right now.
See your traces liveThe decision that broke it is in there somewhere.
For twenty years, we built observability for systems that do what they're told. A function takes inputs, returns outputs. Add a log line. Done.
“A trace isn't a log. It's a map of every decision your agent made, in the order it made them, with full context at each point.”
Ready to stop guessing what your agent decided and just know?
One SDK. Full visibility.
Connect in 2 minutes
Drop the Syrin SDK into your existing agent code. It auto-detects your framework - LangChain, AutoGen, LlamaIndex, custom. No config. No refactoring.
See your first trace immediately
Open the Syrin dashboard. Every LLM call, tool use, and memory read appears as a structured trace - with full inputs, outputs, timing, and token cost.
Find what failed and exactly why
Click any failing span. Syrin surfaces the root cause in plain English - not a stack trace, not a log ID. The exact decision that went wrong, explained.

Book 20 min with our team
No sales deck. No pitch. We get on a call, understand your agent setup, and either show you how Syrin solves it right now - or take your problem back to our engineers and build it.
Book a free callWe have shipped features in <2 weeks after a single user call. If your problem is real and affects other teams running agents in production, it goes on our roadmap - and you'll be the first to use it.
From 'something broke' to 'here's the exact step.'
What used to take hours of log archaeology now takes minutes. The trace shows you exactly where to look.
Every LLM call, tool use, and memory operation, captured automatically. No manual instrumentation.
Works with your existing agents. Drop in the SDK and traces start flowing. No refactoring required.
Teams using Syrin traces resolve production incidents 3× faster than teams using logs alone.
Your agents are deciding things right now.
Don't find out what they decided from a customer complaint.
