What's inside the installer
CODEXT is built with Tauri, a Rust-based desktop framework. Here's exactly what gets installed on your machine.
Binary
codext.exe / codext.tech
The main application binary. Compiled from Rust + WebView2 (Windows) or WKWebView (macOS). No embedded scripts or eval().
Config
Local config file
Stores your settings (theme, excluded paths, size cap). Written to your OS app data directory. Never transmitted anywhere.
License
License token (Pro only)
Encrypted license token stored locally after activation. No phone-home after initial validation. Works offline permanently.
Temp
Shallow clones (optional)
When you clone a GitHub repo, it lands in your system temp folder. CODEXT reads it, bundles it, then you can delete it manually or let the OS clean it.
No telemetry
Zero analytics
No analytics SDK, no crash reporting service, no usage metrics. If CODEXT crashes, nothing is sent anywhere.
No background
No background processes
CODEXT does not install system services, launch agents, or startup items. It runs only when you open it.
SHA256 Checksums
After downloading, verify the file integrity by comparing the SHA256 hash. The checksums for each release are listed on the changelog page and in the GitHub release notes. On Windows: certutil -hashfile CODEXT-Setup.exe SHA256. On macOS: shasum -a 256 CODEXT.dmg.
