The short version
- Each has a real cost: Metasploit the free Framework edition is command line only; the web interface is Pro only; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
- They diverge on capability: Metasploit covers Exploit database, Weka covers Classification.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Metasploit
- The free Framework edition is command line only; the web interface is Pro only
- Automated exploitation, automated credential attacks and antivirus evading dynamic payloads are restricted to Metasploit Pro
- Reporting, audit wizards, task chains and closed loop vulnerability validation are Pro only
- Rapid7 publishes no price for Metasploit Pro and routes buyers to contact sales
Weka
- The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
- Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
- Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture

Questions people ask
- Is Metasploit or Weka better?
- Neither clearly leads. Metasploit starts at Free and Weka at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Metasploit or Weka?

- Does Metasploit or Weka run on more platforms?
- Metasploit runs on Desktop, Cli. Weka runs on Linux, Mac, Windows.
- Can I use Metasploit for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Metasploit best used for?
- Metasploit is most often used for penetration testing and exploit development against known vulnerabilities, validating whether a reported vulnerability is actually exploitable, running phishing and credential attack simulations on the pro edition. Of those, penetration testing and exploit development against known vulnerabilities and validating whether a reported vulnerability is actually exploitable are not what Weka is typically brought in for.
- What can Metasploit do that Weka cannot?
- Metasploit covers Exploit database, Payload generation, Post-exploitation, Evasion modules. Weka covers Classification, Regression, Clustering, Association rules.
