## Why Lithe
Codex, Claude Code, and other AI coding tools can now handle much of the implementation work. Developers still need an IDE to understand the generated code, follow symbols, run and debug the project, and review every diff. Keeping a heavyweight development environment open for those tasks can mean several gigabytes of resident memory.
## Meet Lithe
Lithe is a lightweight IntelliJ IDEA alternative built first for Java and Spring Boot developers. It keeps the core workflows for browsing, editing, navigation, search, Maven, run and debug, Git diff review, local history, and databases.
The Lithe application typically uses about **300–400 MB of baseline memory** after opening a regular project. Language servers, terminals, build tools, debuggers, and database helpers start on demand. Actual usage varies with the project and active services.
> **AI writes the code. Lithe helps you understand it, run it, and review it.**
## If macOS says it cannot open `Lithe.app`
If macOS says that Apple cannot verify whether `Lithe.app` contains malware, the manually downloaded package may not yet be notarized by Apple. First confirm that the app came from the trusted GitHub Releases, then use one of these methods:
1. In **Applications**, Control-click `Lithe.app`, choose **Open**, and choose **Open** again in the confirmation dialog.
2. If macOS still blocks it, open **System Settings > Privacy & Security**, click **Open Anyway** next to the security warning, and launch the app again.
3. You can also remove the quarantine attribute in Terminal:
 [code] 
Only use these steps for an app whose source you trust. Homebrew installations usually do not require manual quarantine removal.
