## What it is
Glimpse is an open-source diagnostics platform for ASP.NET web applications that inspects requests in real time, profiling server-side activity, database calls, view rendering, and routing. It presents insights in-browser via HTML/CSS/JS with no proprietary browser plugin required.

## Use cases
- profile asp.net mvc request performance with a gantt chart
- debug slow or excessive database queries in a web app
- see how asp.net routes are matched for a request
- inspect view resolution and rendering paths
- view trace statements without digging through log files
- decode viewstate in asp.net webforms
- inspect ajax and historical requests

## When to choose
- you maintain a legacy ASP.NET or ASP.NET MVC/WebForms application and need in-browser diagnostics
- you want lightweight profiling without a proprietary browser extension
- you need route debugging and server configuration visibility in .NET

## When to avoid
- you are starting a new project - the project is abandoned and v2 work moved to an unfinished prototype
- you use ASP.NET Core or non-.NET stacks - Glimpse targets classic ASP.NET
- you need actively maintained monitoring - prefer modern APM or Application Insights tooling

## Facets
- artifact type: library
- maturity: abandoned
- function: monitoring, tracing, logging, benchmarking, middleware
- domain: web-development, developer-tools, performance
- platform: dotnet
- tags: aspnet, profiling, diagnostics, request-inspection, gantt-chart, route-debugging, nuget, debugging, web-server, iis
