Integrates with what you’re already doing
Already logging using NLog, Log4Net, or pretty much any other logging framework? No problem – Loupe can capture that information too and integrate it with the rest of the data.
Using common .NET technologies like ASP.NET, Entity Framework, and Web API? Loupe has agents for each that gather useful performance and error information to handle many logging needs out of the box.Find out more

“Loupe is an indispensable tool for us and even more important is the very positive feedback I get from our customers for being proactive in identifying issues and fixing them without the need of those cumbersome ‘I need your logs’ conversations”
Andreas Schneider, CEO
“We are a small team running a huge code base across many servers and environments. Without Loupe in the mix, we could never achieve the level of stability and issue resolution time we have. I can’t imagine our team without Loupe in the mix”
Chris Rajczi, Developer

Loupe Technical FAQ
What makes Loupe different from other tools?
Loupe combines logging with error reporting. This unique combination of centralized log management with automated error analysis saves you time pinpointing the root cause of runtime errors and performance issues.
Loupe is also extremely efficient and reliable in production. All Loupe data is buffered first to memory then to local disk so it is super fast and nothing is lost even if the network goes down.
How safe is Loupe? Will it slow down my application, use a lot of memory or disk?
Loupe was designed from day one to do no harm.
- It's safe and efficient in highly multithreaded or single threaded applications.
- It does its work on background threads to incur negligible latency on your applications.
- It makes efficient use of memory and writes data to compressed files to mimimize disk consumption.
- It manages local storage consumption within configurable storage limits
- Streaming log transmission is restartable, transactional and tolerant of intermittent network connectivity.
Is it difficult to integrate Loupe with my software?
Not at all. The simple setup captures unhandled errors as well as any existing logging you're already doing and it takes just a couple minutes.
What type of applications does Loupe work with?
Loupe captures all the logging you're already doing via System.Diagnostics, Console, log4net, Nlog, and it also integrates easily with your homegrown logging system.
What are the key parts of Loupe?
Loupe consists of three parts:
- Loupe Agent is a lightweight .NET assembly that runs in-process within your applications safely and efficiently collecting errors, events, metrics and configuration information.
- Loupe Desktop is a desktop application used to manage and analyze Loupe logs.
- Loupe Server is a powerful web application brings your data and your team together.
