lift/framework
This system is the Lift web framework, a Scala-based toolkit for building web applications. It provides core infrastructure for asynchronous processing, HTTP request handling, and template rendering, while offering utilities for JSON, Markdown, and HTML manipulation. The codebase has been significantly refactored to modernize its build system, migrate to Jakarta Servlet APIs, and support Scala 2.13 and 3, while removing numerous legacy components and deprecated integrations.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 7ea53e8dc2 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
