Karve vs Visual Studio 2022 HTTP files
Visual Studio's built-in HTTP editor is excellent beside an ASP.NET Core project. Karve runs the same portable REST files in a dedicated native Windows workspace, especially when those files are spread across more than one solution.
Side by side
| Dimension | Karve | Visual Studio 2022 |
|---|---|---|
| Context | Standalone workspace across files and repositories | Built into the currently open solution and project |
| File compatibility | Portable REST subset of .http/.rest | .http/.rest with Visual Studio-specific variables and helpers |
| Request generation | No endpoint generation in v1 | Endpoints Explorer can create requests from ASP.NET Core routes |
| Methods | GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS | Also documents TRACE and CONNECT plus optional HTTP version selection |
| Response workflow | JSON tree, raw body, headers, request snippet, and persistent searchable history | Response pane beside the editor; no built-in request history according to Microsoft |
| Environments | Selectable per-file dotenv environments; file variables win | http-client.env.json, process environment, and dotenv helpers |
| Licensing | $29.99 sale ($39.99 regular), one-time | Bundled with Visual Studio 2022 (free Community edition; paid Professional/Enterprise) |

- You want persistent searchable history in a dedicated client.
- You want to run files without opening a full IDE.
- Your workflow uses ordinary REST syntax shared by multiple editors.
Choose Visual Studio when
- The request belongs to the ASP.NET Core solution already open.
- Endpoints Explorer should generate requests from project routes.
- You need Visual Studio-specific helpers or HTTP version controls.
- You want request execution directly beside the implementation.
FAQ
Can Karve run Visual Studio files?
Yes, when they use ordinary REST request lines, headers, bodies, separators, and variables. Visual Studio helpers and methods outside Karve's supported set do not carry over.
Why use a separate app?
Karve gives files from multiple repositories one workspace, response viewer, environments, and persistent searchable history without opening every solution.
Does Karve generate requests from endpoints?
No. Endpoints Explorer is a Visual Studio advantage. Karve focuses on organizing and running files that already exist.
