CloneWorks vs jscpd

Both stand on code clone detection tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

CloneWorks

Free plan LinuxMacWindows

CloneWorks provides code preparation and token-based clone detection, with configurable extraction granularity and similarity threshold. Its prerequisites, Cygwin limitation, experimental partition sizing, and license conditions are important considerations.

jscpd

Free plan Open source APILinuxMac+2

jscpd combines repository-wide clone detection with build thresholds, reports, and developer workflow integrations. Its experimental semantic detection and language-specific dead-code limits are worth considering when choosing which checks to rely on.

CloneWorks: what it does well

Supports Java, C, C++, C#, and Python inputs.
Extracts code at block, function, or file level.
Threshold can range from 0.0 to 1.0.
Available for Linux, macOS, and Windows.

What to know first

Requires FreeTXL, gcc, make, and Java 7 or later.
Input builder is slower on Cygwin.
Partition size must be determined experimentally.
License requires free distribution and provides no warranty.

jscpd: what it does well

Supports 224 languages, according to the project
Can enforce duplication thresholds in builds
Offers multiple report formats, including SARIF
Runs as a native binary without Node.js
Free and open source

What to know first

Semantic clone detection is experimental
Dead-code analysis covers only specified languages
Rust dead-code analysis needs compiler diagnostics
