Karve — a native Windows alternative to Yaak
Karve and Yaak want the same things for you: local data, no forced account, requests you can put in Git. The difference is where each one puts its weight. Karve bets on the standard .http format in a native WinUI 3 Windows app, bought once. Yaak is a cross-platform client with broader protocol coverage that keeps workspaces in its own file format — free for personal use, licensed yearly for work.
Why Karve
What you get
The local-first idea applied to files you already have: Karve works directly on standard .http/.rest files, gathers them from every repo into virtual folders without moving them, and adds environments, tabs, and persistent searchable history — in a native Windows app with a one-time price.
What it leaves out — on purpose
No GraphQL, gRPC, WebSocket, or SSE; no plugins; no macOS or Linux builds; source not public. Karve trades protocol breadth for a smaller, native surface built around one format done well.
Side by side
| Dimension | Karve | Yaak |
|---|---|---|
| Platform & engine | Native WinUI 3, Windows only | Cross-platform desktop (Windows, macOS, Linux) |
| Licensing & price | Proprietary; $29.99 sale ($39.99 regular), one-time | Source-available; free for personal use, ~$50 per user/year for commercial use |
| Request format | Standard .http/.rest files; editor-agnostic, diff in Git | Own workspace format, exportable to plain files for Git sync |
| Organize requests | Virtual folders over files from any repo; files never move | Workspaces and folders inside the app |
| Environments & history | Per-file .env environments; persistent, searchable history saved locally across sessions | Environments with variables; response history per request |
| Protocols | REST / HTTP | REST, GraphQL, gRPC, WebSocket, SSE |
| Extensibility | None — deliberately small surface | Plugin system |
| Account required | No | No |
Yaak details reflect its public product and pricing pages as of July 2026; Karve's reflect the shipping v1.0.5 scope. "On the roadmap" means planned, not yet available.
Where Karve fits
Yaak deserves real credit: it's local-first, account-free, and honestly priced — the same instincts Karve is built on. If you need GraphQL, gRPC, or WebSocket in one client, Yaak is the better tool and this page won't pretend otherwise.
The fork in the road is the file format. Yaak keeps requests in its own workspace format that syncs out to files; Karve works directly on the .http files that VS Code, Visual Studio, and JetBrains IDEs already understand — the same file your teammate runs in their editor is the one you organize and run in Karve, with nothing exported and nothing to keep in sync. Add a native Windows app instead of a cross-platform shell, and a one-time purchase instead of a yearly commercial license, and Karve is the simpler bet for REST work on Windows.
Why developers choose Karve
- Requests stay in the standard .http format — no app-specific workspace between you and your files.
- Native WinUI 3 speed and Windows integration (Mica, file associations) instead of a cross-platform shell.
- One-time $29.99 during the current sale ($39.99 regular) — no separate commercial license renewing every year.
- Virtual folders gather .http files from every repo without moving them.
- Persistent, searchable request history across sessions, saved locally.
One format, one platform, one payment — done well.
FAQ
Both are local-first — what's the difference?
The file format and the platform. Karve works directly on standard .http files in a native Windows app bought once; Yaak is cross-platform with broader protocols and its own workspace format, licensed yearly for commercial use.
Can Karve open Yaak workspaces?
No — Yaak's format is its own. Karve reads plain .http/.rest files, which is exactly why they stay portable across editors and tools.
Is Karve free for personal use like Yaak?
Karve is a one-time purchase with a 15-day free trial — no personal/commercial split, no yearly renewal.
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:
