Alternatives to Skylos

{"intro": "Skylos brings security-regression detection, secret scanning, dead-code and quality checks, and checks for mistakes introduced by AI into one open-source static-analysis workflow. Its CLI runs locally without an account and supports CI checks across many languages and deployment configuration. The free VS Code extension adds inline diagnostics and optional AI verification, while cloud options connect GitHub pull requests and OIDC, with Slack and Discord notifications available. Local scans stay on the machine unless a report or cloud action sends data.\n\nIts free plan combines local scans with one cloud project, 10 stored scans, and seven days of history. Paid credit packs begin at $9 once, while Enterprise pricing is custom; retention and capacity expand by plan. Supported platforms include Linux, macOS, Windows, web, API, extensions, and self-hosting. Skylos does not claim SOC 2, ISO 27001, or CSA STAR certification. Consider whether you need C#-specific editor warnings, dependency and license governance, Python taint analysis, mobile testing, runtime web testing, or a different pricing model.", "rows": [{"ref": "sw:puma-scan", "name": "Puma Scan", "best_for": "C# teams using Visual Studio and build gates", "pricing": "Free plan; paid from $299/user/yr; 30-day trial", "key_difference": "Puma Scan focuses on real-time C# warnings in Visual Studio, including AI-generated code, rather than Skylos’s multi-language analysis.", "choose_when": "Choose it when C# and Visual Studio feedback, configurable severity gates, and GitHub Actions, GitLab CI, or Azure DevOps matter most."}, {"ref": "sw:snyk-open-source", "name": "Snyk Open Source", "best_for": "Dependency vulnerability and license management", "pricing": "Free plan; paid from $25/mo", "key_difference": "Snyk Open Source analyzes open-source dependencies, licenses, pull requests, CI/CD, and live environments instead of Skylos’s source-focused checks.", "choose_when": "Choose it when dependency reachability, exploit prioritization, automated upgrade pull requests, continuous monitoring, or license policies outweigh Skylos’s code analysis."}, {"ref": "sw:horusec", "name": "Horusec", "best_for": "Free multi-language security scanning with Docker", "pricing": "Free plan", "key_difference": "Horusec combines 20 security tools across 18 languages, Git-history secret searches, dashboards, and configurable CLI analysis, while requiring Docker for full coverage.", "choose_when": "Choose it when broad free language coverage, Git-history scanning, web metrics, or a VS Code workflow fits better than Skylos."}, {"ref": "sw:pysa", "name": "Pysa", "best_for": "Python taint analysis with custom data-flow models", "pricing": "Open source", "key_difference": "Pysa specializes in configurable Python source-to-sink taint analysis with models, sanitizers, SAPP results, and a Language Server Protocol extension.", "choose_when": "Choose it when precise Python data-flow modeling and sanitizer rules matter more than Skylos’s broader language and issue coverage."}, {"ref": "sw:semgrep-code", "name": "Semgrep Code", "best_for": "Multimodal SAST with broad language and workflow integrations", "pricing": "From $15/user/mo", "key_difference": "Semgrep Code supports 35+ languages, combines deterministic and AI detection, and supplies pull-request remediation guidance beyond Skylos’s scope.", "choose_when": "Choose it when multimodal detection, tailored remediation instructions, extensive SCM and CI integrations, or IDE notifications are priorities."}, {"ref": "sw:mobsf-static-application-security-testing-tool", "name": "MobSF", "best_for": "Mobile application security and penetration testing", "pricing": "Free plan", "key_difference": "MobSF tests Android, iOS, and Windows packages with static, dynamic, and malware analysis, whereas Skylos analyzes source and deployment configuration.", "choose_when": "Choose it when mobile binaries, runtime behavior, API interactions, exported reports, or mobile-focused CI integrations are required."}, {"ref": "sw:veracode-dast", "name": "Veracode DAST", "best_for": "Automated runtime testing of web apps and REST APIs", "pricing": "Pricing on request; free trial", "key_difference": "Veracode DAST probes live web applications and APIs, including authenticated workflows and assets behind firewalls, rather than performing Skylos’s static source analysis.", "choose_when": "Choose it when scheduled, scalable runtime scans, API business-logic testing, low false-positive reporting, or PDF, JUnit, and CSV exports are needed."}]}
