System Requirements

Curlex is a native desktop application built with Tauri and Rust. Because it uses your operating system's built-in webview rather than bundling a full browser, it is significantly lighter than Electron-based tools — the installer is approximately 15 MB and memory usage stays low even with many tabs open.

Supported Operating Systems

Platform	Supported versions
macOS	macOS 11 Big Sur and later
Windows	Windows 10 (64-bit) and later
Linux	Not currently supported

macOS

Curlex is available in two builds:

Apple Silicon (M1, M2, M3, M4 and later) — download the aarch64 build for native performance on Apple Silicon Macs.
Intel (x86-64) — download the x64 build for older Intel-based Macs.

If you are unsure which chip your Mac has, click the Apple menu () → About This Mac. The chip or processor line will say either "Apple M..." or "Intel Core...".

Windows

Curlex supports Windows 10 and Windows 11, 64-bit only. 32-bit Windows is not supported.

Hardware

Component	Minimum
CPU	Any 64-bit processor (Intel, AMD, or Apple Silicon)
RAM	512 MB free
Disk space	100 MB for the application; additional space for request history and response artifacts
Display	800 × 600 minimum resolution. 1 280 × 800 or larger recommended for comfortable two-panel layout.
Internet	Required only for sending API requests and (optionally) Git Sync. The app itself works completely offline.

What Curlex Uses from Your OS

Curlex integrates with several native OS features:

Feature	What it is used for
OS Keychain	Storing OAuth tokens, the Vault encryption key, and Vault secrets. On macOS this is Keychain Access; on Windows it is Credential Manager.
Native file dialogs	Selecting files for binary upload, importing collections, and exporting reports.
System Git binary	Git Sync uses the Git executable already installed on your system. See Git Sync for details.
System webview	Curlex renders its interface using WKWebView (macOS) or WebView2 (Windows) — the same engine your browser uses. No separate browser installation is required.

WebView2 on Windows

Curlex on Windows uses Microsoft Edge WebView2. WebView2 comes pre-installed on Windows 11 and on most up-to-date Windows 10 systems. If it is not installed, Windows will prompt you to install it the first time you launch Curlex — the download is approximately 2 MB and the installation takes under a minute.

Network

Curlex itself makes no outbound connections. The only network activity is:

Your API requests — sent from your machine to whatever server you configure.
Git Sync — if enabled, pushes and pulls to a Git remote you have configured.
Auto-update checks — Curlex checks for updates in the background and notifies you when one is available. No data about your usage is sent.

No telemetry, no usage tracking, no analytics.
