Karve — a native Windows alternative to Insomnia
Karve leads with Windows-native quality: a WinUI 3 app — not an Electron/React shell — that starts fast, follows your system theme with Mica, and keeps your requests as plain .http files organized into folders on disk. Insomnia is a cross-platform Electron client built around accounts, plugins, and a CLI. For a Windows team that just wants to open a file and run it, Karve is the shorter path — bought once, no sign-in.
Why Karve
What you get
A native WinUI 3 app that feels at home on Windows — no Electron, no storage-mode decision, no sign-in. Your requests are .http files organized into folders on disk, bought once. Install from the Store, open a file, run.
What it leaves out — on purpose
No plugin hub, built-in Git Sync, CLI, or GraphQL/gRPC, and Windows-only. Karve keeps a narrow surface so there's less to learn and nothing to wire up — you version files with your normal Git workflow.

Where Karve fits
Both can run offline, so local-first alone isn't the difference — the feel of the app on Windows is. Karve is built directly on WinUI 3, so it starts quickly, follows your system light/dark theme with Mica, and behaves like a first-class desktop app rather than a web view in a wrapper.
For a team where most developers are already on Windows, that's a shorter path from install to first request: buy it once from the Store, open a .http file, and run. No plugin hunting, no storage-mode decision, no sign-in.
Why developers switch to Karve
- Native WinUI 3 — starts fast and follows your system theme with Mica, not a web view in an Electron wrapper.
- One-time $29.99 during the current sale ($39.99 regular); every v1.x update included — no per-user tiers or account gating.
- Requests are plain .http files on disk, versioned with your normal Git workflow — no storage-mode decision.
- No sign-in and no cloud sync to configure — fully local.
- Environments and persistent, searchable history built in.
A smaller, native Windows tool you own outright.
FAQ
Is Karve just another local-first client like Insomnia?
Both run offline, but Karve is a focused native Windows app — fast, themed with Mica, one-time price — with your requests as plain .http files. Insomnia is a cross-platform Electron app built around accounts, plugins, and a CLI.
Does Karve have Git Sync and plugins?
Karve doesn't need them — your requests are already plain .http files on disk, so you version them with your normal Git workflow, in any repo.
Does Karve support GraphQL?
Karve is built for REST and the .http format — that focus keeps it fast and simple. GraphQL and gRPC aren't part of it.
On Karve's roadmap
Everything above ships in Karve v1.0.5 today — including environments and persistent, searchable history. A few more things are planned for upcoming v1.x updates, included in the one-time price and on the way:
