LINQPad Query Plan Visualizer
An SQL Server and PostgreSQL query execution plan visualizer for LINQPad.
LINQPad allows users to execute LINQ queries, but it has no way to display the query execution plan so I started an open-source plugin for LINQPad which shows the query execution plan.
Features:
- View query execution plan inside LINQPad
- View missing indexes for query
- Share plan to https://www.brentozar.com/pastetheplan/ or https://explain.dalibo.com/
- Create missing indexes directly from LINQPad
- Open plan in SQL Server Management Studio or another default app
- Save plan to disk
I’m a backend engineer and software architect with 17+ years of .NET, mostly in banking and fintech: payment and transaction processing, public APIs, and the internal platforms other teams build on. I’ve led teams and a platform unit, and I stay hands-on in the code, increasingly through AI coding agents like Claude Code and Codex.
Alongside that, I build open-source .NET libraries and developer tools with 45M+ NuGet downloads: DuckDB.NET, EntityFramework.Exceptions, EFCore.Visualizer and others. That work sits where .NET meets the database: native interop, Native AOT extensions for DuckDB and PostgreSQL, and tooling that makes query plans easier to debug. I also speak about .NET and databases at conferences like NDC, KCDC and .NET Conf.
