NativeRest

NativeRest is a fast, native (non-Electron) REST API client for Windows, macOS, and Linux that runs fully offline, imports Postman and Insomnia collections in one click, and uses a fraction of the memory of Electron-based rivals.

What is NativeRest?

NativeRest is a native REST API client from NativeSoft that positions itself as the anti-Postman: a 100% native desktop application for Windows (and now macOS and Linux) built without Electron, Chromium, Node.js, or JavaScript frameworks. The payoff is a client that starts instantly, uses dramatically less RAM and CPU than its Electron-based rivals, and runs entirely offline — collections, environments, and requests stay in local workspaces on your machine, with no mandatory account or cloud sync. It imports Postman and Insomnia collections, environments, and variables in one click, and offers the everyday API workflow features developers expect: folders with up to 8 levels of nesting, layered system/global/workspace/environment variables, built-in functions (hash, hmac, base64, random, date, math, string), simple single-line response tests, custom color-coded HTTP methods, and code snippet generation in 15+ languages. A preconfigured proxy server, cloud workspaces, cross-device sync, and collaborative team workspaces live on the paid cloud tiers. The interface is multilingual (10 languages) with light/dark themes, and a portable version ships as a single ~8MB executable needing no admin rights. On Dealify it's offered at $33 to $99 lifetime for one, two, or three codes. The trade-offs are real: this is a young solo-developer product whose base tier is offline-only, whose Mac/Linux builds are new, and whose '100x faster' claim is about memory efficiency more than feature depth — so compare it against Postman's free tier before you buy.

Key Features

Who is it for?

• Developers who are tired of Electron bloat and want a snappy, low-memory REST client that opens in an instant
• Privacy-conscious engineers who want offline, local-only workspaces with no mandatory account or cloud sync
• Windows-first developers (or anyone who wants a portable ~8MB client to carry on a USB stick)
• Solo devs and small teams migrating from Postman or Insomnia without rebuilding their collections
• Developers who work across multiple languages and want quick code snippet generation in 15+ languages

Who is it NOT for?

• Teams deeply invested in Postman's team libraries, monitors, docs, and scripting ecosystem — the switching cost is high
• Developers who need cloud-based collaborative workflows on the cheap, since sync and team features require the paid tiers
• macOS- or Linux-first teams who want a proven, long-matured native client — Windows is the mature platform here
• Power users who rely on Postman-style scripted test suites, assertions, and CI integration
• Anyone who only ever sends the occasional request and is already served fine by a free tier
