| Spec score · Code Clone Detection Tools | 8.6 (#1) | 8.6 (#2) |
| Clone types | Without a reserved-word list, the tool detects type 1 clones; with one, it detects type 1 and type 2 clones. | It detects exact clones by default and offers opt-in detection for renamed, near-miss, and semantic clones; semantic detection is described as experimental. |
| License | The repository license file includes the MIT License for CCFinderSW and a BSD 3-clause license for ANTLR components. | The project and its published packages use the permissive MIT license. |
| Purpose | CCFinderSW is a token-based code clone detection tool that detects similar code fragments and outputs clone pairs. | jscpd scans source code for duplicate code and can fail a build when duplication exceeds a configured threshold. |

In their own words
CCFinderSW
CCFinderSW is a free, open-source command-line tool that detects similar code pairs through token-based clone matching. It takes a source directory, a language, and an output file as command-line arguments. The default minimum clone-token threshold is 50 and can be changed with the -t argument. Output can use CCFinder, CCFinderX, CCFinderSW text, or JSON formats, and clone-pair results can be read by Gemini or CCFX. A comment rule file is required for the target language; a reserved-word list is optional but recommended. Without that list, the tool detects type 1 clones; with it, it detects type 1 and type 2 clones. It excludes pairs containing inserted or deleted sentences. The implementation is Java-only, and the project recommends Java 8 or later. Windows is the listed platform, with Windows 10 Pro named as its test environment. The repository offers a CCFinderSW-1.0.zip download and includes an MIT license for the project; bundled libraries use Apache License 2.0.
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.
