Karve — the same .http files, without the IDE
This isn't a rivalry — it's a relay. The JetBrains HTTP Client is one of the best reasons the .http format exists, and if you live in IntelliJ or Rider you should absolutely use it there. Karve picks up where the IDE stops: a standalone native Windows app for the same files — for the machine without an IDE license, the QA teammate, or the moment you want to run requests without opening a project.
Why Karve
What you get
A dedicated native Windows home for the .http files you already write: double-click a file and run it, gather files from every repo into virtual folders without opening projects, keep per-file .env environments and a persistent searchable history — no IDE, no JVM, no per-project window.
What it leaves out — on purpose
No response handler scripts or request chaining, no http-client.env.json support (Karve uses plain .env), no CLI for CI, no code completion tied to your Spring or ASP.NET routes. Inside the IDE, JetBrains keeps those advantages.
Side by side
| Dimension | Karve | JetBrains HTTP Client |
|---|---|---|
| Runs as | Standalone native Windows app (WinUI 3) | Feature inside JetBrains IDEs; separate free ijhttp CLI (needs a JDK) |
| Licensing & price | $29.99 sale ($39.99 regular), one-time | Bundled with paid JetBrains IDE subscriptions; CLI free |
| Request format | Standard .http/.rest files | Same .http format |
| Scope | Any file on disk; virtual folders gather files across repos | Files within the open IDE project |
| Environments | Plain .env files (dotenv), global active environment | http-client.env.json (+ private variant) |
| Scripting | None — requests stay declarative | JavaScript response handlers, request chaining, tests |
| History | Persistent, searchable, saved locally across sessions | Recent responses kept per project |
| CI / automation | None | ijhttp CLI runs files in CI |

Where Karve fits
The JetBrains HTTP Client's strength is also its boundary: it lives inside an IDE window, scoped to the open project, on a machine with a JetBrains license. That's perfect while you're deep in the code. It's less perfect when your .http files are spread across a dozen services, when a teammate without an IDE seat needs to reproduce a call, or when opening a heavy IDE just to send one request feels absurd.
Karve is the standalone half of that workflow. The same files — unchanged, still in Git, still runnable in the IDE — get a fast native Windows app of their own: organized across repos in virtual folders, with environments, tabs, and a history that survives restarts. Keep the IDE client; give the files a home outside it.
Why developers choose Karve
- Run .http files without opening an IDE — double-click and send.
- One workspace over every repo's request files, not one project window at a time.
- No JetBrains subscription or JVM needed — one-time $29.99 during the current sale ($39.99 regular).
- QA and teammates without IDE licenses get the same requests, same format, native app.
- Persistent searchable history and per-file .env environments built in.
Same format the IDE taught you — in a home of its own.
FAQ
Do my JetBrains .http files work in Karve?
Yes — same plain-text format: requests, headers, bodies, ### separators, @variables, and {{variable}} references run as-is. JetBrains-specific extras — response handler scripts and http-client.env.json — are the exception: Karve doesn't execute or read those.
Can I use the JetBrains HTTP Client without an IDE?
Only as ijhttp, the free CLI runner (JDK required) — there's no standalone JetBrains GUI. Karve is a standalone native Windows GUI for the same files.
Does Karve read http-client.env.json?
No — Karve uses plain .env files in its Environments panel. The {{variable}} references in your .http files stay identical; see the environments guide for the mapping.

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:
