CodeSonar vs Skylos

CodeSonar is AdaCore’s static application security testing solution for finding security and quality defects in source code and compiled binaries. It supports C/C++, Java, C#, Kotlin, Python, Go, Rust, JavaScript and TypeScript. Abstract interpretation and symbolic execution examine feasible execution paths across procedures and modules. Binary analysis covers mixed-language environments and cases where source is unavailable. Security coverage includes OWASP Top 10, SANS/CWE 25, SEI CERT C/C++ and DISA STIG; coding standards include MISRA-C, MISRA-C++, AUTOSAR C++, JSF++ and CERT. Integrations include Visual Studio, GitLab, Jira, Jenkins and VS Code, alongside project-management, CI/CD and IDE workflows. Pull-request scans, custom security rules and report exports to PDF, HTML or XML are supported. AdaCore offers on-premises, air-gapped and private-cloud deployment. The tool runs on supported 64-bit Windows and Linux distributions with glibc 2.39 or higher. Pricing is on request, with a trial available.

Skylos is an open-source static analysis tool that checks source code for security regressions, secrets, dead code, quality issues, and mistakes introduced by AI. It analyzes Python, JavaScript and TypeScript, Go, Java, Kotlin, PHP, Rust, Dart, C#, Shell, and deployment configuration, with analysis depth differing by language. Its CLI runs locally without an account for scans and CI checks. A free VS Code extension offers inline diagnostics and optional AI verification through OpenAI or Anthropic API keys. Cloud options include GitHub pull request workflows, OIDC identity, and optional Slack and Discord notifications. A normal CLI scan remains on the user's machine; Cloud receives data when reports are uploaded, cloud actions are triggered, or the public scan endpoint is used. Uploaded reports may include findings, file paths, snippets, and scan metadata. Skylos says it does not currently claim SOC 2, ISO 27001, or CSA STAR certification. The free plan includes one cloud project, 10 stored scans, and seven-day history. One-time credit packs begin at 9.00 USD. Skylos supports API, extension, Linux, macOS, self-hosted, web, and Windows use.
