SeaHorn vs Semgrep Code

SeaHorn is a free, open-source framework for automated analysis of C and other LLVM-based programs, developed mainly for research in automated verification. It is not an out-of-the-box static analyzer. Its frontend prepares LLVM IR bitcode, and its middle end converts optimized bitcode into verification conditions written as Constrained Horn Clauses. Backend engines use SMT-based model checking, including PDR/IC3 techniques, and CRAB can provide numerical invariants through abstract interpretation. SeaHorn supports abstract interpretation, context-sensitive pointer analysis, bounded model checking, constrained-Horn-clause software model checking, and termination or non-termination analysis. For C programs with assertions, `sea pf` translates the program, generates and solves verification conditions, displays invariants for safe results, or saves a counterexample for violations. `sea inspect` reports program structure and can produce memory or call-graph data. The framework also checks generated clauses for inconsistent code fragments using path coverage. Docker is described as the easiest starting point, with a nightly image refreshed daily. Building requires LLVM, Z3, and Boost, whose exact versions change. SeaHorn runs on Linux, macOS, or self-hosted systems under a modified BSD license.

Semgrep Code is a cloud-based static application security testing product for finding vulnerabilities in source code and helping developers address them. It combines deterministic analysis for issues such as XSS and SQL injection with AI analysis aimed at complex flaws, including IDOR and business logic vulnerabilities. Pull requests can carry tailored, step-by-step remediation instructions, and the product supports 35 programming languages. Semgrep lists integrations with GitHub, GitLab, Bitbucket, Jenkins, CircleCI, Azure and Buildkite, plus VS Code and IntelliJ extensions and Slack, email and webhook notifications. The Free Edition includes Code and Supply Chain, with scanning for up to 10 repositories and a limit of 10 contributors. Teams supports up to 500 private repositories; Enterprise has no repository or contributor limit. For local or fully CI-based scans, code stays on the user's computer or CI environment; opting into AI processing sends part of a file containing a finding to a model. The Free Edition costs nothing. Teams — Code is listed at $30 a month.
