Horusec vs Skylos

Horusec is a static code analysis tool for identifying security flaws during development. It scans source code and searches project files and Git history for leaked keys and other security issues. The project describes analyzing 18 languages with 20 security tools; listed coverage includes C#, Java, Kotlin, Python, Ruby, Golang, Terraform, JavaScript, TypeScript, Kubernetes, PHP, C, HTML, JSON, Dart, Elixir, Shell, and Nginx. Analysis is configurable through CLI resources. Developers can use its command-line interface, while DevSecOps teams can add it to CI/CD pipelines; a Visual Studio Code extension is also provided. Horusec-Web offers vulnerability dashboards, false-positive controls, authorization tokens, and vulnerability updates. Horusec Platform integrates with the CLI to visualize and manage vulnerabilities, and supports native Horusec, LDAP, and Keycloak authentication. Its repository was archived by its owner on March 19, 2025 and is read-only. Running Horusec with all its tools requires Docker; the platform requires RabbitMQ and PostgreSQL. The open-source plan is free under Apache License 2.0.

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.
