Side by side

Astrée vs SeaHorn

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

Astrée

Paid LinuxWindows

Astrée covers a broad range of static-analysis needs, from run-time errors to concurrency and coding rules. Buyers should confirm pricing and license capacity for their team before choosing it.

Visit Astrée

Choose SeaHorn for research-oriented verification of C and other LLVM-based programs, especially when its model-checking and invariant-analysis components fit your workflow. Look elsewhere for a turnkey static analyzer or a platform beyond Linux and macOS.
