JetBrains Rider is a deep, polished cross-platform .NET IDE built on the ReSharper
engine — the gold standard for C# refactoring and analysis. binvim is a
~42 MB single-binary terminal editor with native Vim grammar that still ships
real .NET tooling — csharp-ls, netcoredbg debugging, csharpier,
and Razor — and starts in ~14 ms instead of Rider's 10–30 seconds.
Rider is one of the best .NET IDEs you can use. The ReSharper engine gives it the deepest C# refactorings and inspections anywhere; the graphical debugger is first-class; and it bundles database tools, profilers, test runners, and a full project model in a polished cross-platform GUI. For heavy .NET work — large solutions, complex refactors, integrated profiling — Rider is the right tool and binvim does not try to match its depth.
binvim wins on weight and speed. It is a ~42 MB single binary with ~14 ms
startup against Rider's ~1.5 GB and 10–30 second cold start, with no JVM
and a native terminal UI that runs over SSH. Vim grammar is built in rather than bolted on via a
plugin, and you still get competent .NET support: csharp-ls for completion, hover,
rename and code actions, netcoredbg debugging with conditional and hit-count
breakpoints, csharpier formatting, Razor tree-sitter, and dotnet test/task runners. It
is also free and source-available. For quick edits, remote boxes, and a snappy terminal workflow,
binvim is hard to beat.
Pick Rider when you want the deepest .NET refactoring, a graphical debugger, and a complete IDE. Pick binvim when you want an instant, tiny, Vim-native terminal editor with real .NET support — including over SSH. As with Visual Studio, plenty of developers keep both: Rider for heavy lifting, binvim for speed.
A lightweight, vim-native IDE for .NET work rather than a like-for-like replacement for Rider's depth. Rider's ReSharper engine, graphical debugger, and tooling go far deeper; binvim ships csharp-ls, netcoredbg debugging, csharpier, Razor, and dotnet test/task runners — far lighter and faster.
binvim is ~42 MB and starts in ~14 ms. Rider runs on the JVM, is ~1.5 GB installed, and cold-starts in 10–30 s. binvim trades depth for a tiny footprint, instant startup, and no JVM.
Only at the LSP level via csharp-ls — rename (with a modal preview overlay), code actions, goto-definition, find-references. Rider's ReSharper refactorings and inspections are far deeper.
binvim is free to run and source-available under BSAL. Rider is free for non-commercial use and paid for commercial use. Both run on macOS, Linux, and Windows.
