In their own words
Hound
Hound is a free source code search engine that indexes repositories and offers a web interface and a minimal API. Its Go backend maintains a current index for each repository, while its static React frontend provides the web UI. Search uses regular-expression matching with a trigram index. Hound supports Git, Mercurial, SVN, Bazaar, and local repositories; private repositories can be indexed from local directories or reached through file or SSH-style URLs. By default, it checks configured repository URLs for updates every 30 seconds, with an interval that can be changed per repository. It can be built from source or run from the project's Docker image, and the web UI defaults to localhost:6080. Plugins are available for Sublime Text, Vim, Emacs, and Visual Studio Code. Hound is tested on macOS and CentOS and is expected to work on Unix-like systems, but Windows is not supported. It does not support TLS itself; the README suggests running it behind Apache or nginx. Hound uses the MIT license, and the latest listed release is v0.7.1, published May 3, 2023.
jscpd
jscpd is a free, open-source tool for finding repeated code in repositories. It can fail a build when duplication exceeds a configured threshold, making it usable in local development and CI. The project says it supports 224 languages. Exact clones are detected by default, while renamed, near-miss, and semantic clone checks are optional; semantic detection is experimental.
Version 5 is available as a self-contained native binary that does not need Node.js, with direct macOS, Linux, and Windows binaries for x64 and ARM64. Reports include HTML, JSON, XML, README badges, SARIF, CodeClimate, and OpenMetrics. The GitHub Action can enforce a threshold and upload SARIF for GitHub Code Scanning, and GitLab CI reporters are documented. Developers can also use pre-commit hooks or Docker. A dashboard summarizes project size, duplication, complexity, dead code, and a health score. Dead-code analysis covers JavaScript, TypeScript, and Python, plus Rust when compiler diagnostics are supplied.
