Osmedeus

Osmedeus - A Modern Orchestration Engine for Security

Osmedeus is a security focused declarative orchestration engine that simplifies complex workflow automation into auditable YAML definitions, complete with encrypted data handling, secure credential management, and sandboxed execution.

Built for both beginners and experts, it delivers powerful, composable automation without sacrificing the integrity and safety of your infrastructure.

• Declarative YAML Workflows - Define reconnaissance pipelines using simple, readable YAML syntax
• Multiple Runners - Execute on local host, Docker containers, or remote machines via SSH
• Event-Driven Triggers - Cron scheduling, file watching, and event-based workflow triggers with deduplication and filter functions
• Template Engine - Powerful variable interpolation with built-in and custom variables
• Utility Functions - Rich function library with event generation, bulk processing, and JSON operations
• REST API Server - Manage, trigger, and cancel workflows programmatically
• Distributed Execution - Scale with Redis-based master-worker pattern for parallel scanning
• Notifications - Telegram bot and webhook integrations
• Cloud Storage - S3-compatible storage for artifact management
• LLM Integration - AI-powered workflow steps with chat completions and embeddings

The high-level ambitious plan for the project, in order:

Osmedeus is designed to execute arbitrary code and commands from user supplied input via CLI, API, and workflow definitions. This flexibility is intentional and central to how the engine operates see Security Warning page for more details.

Think twice before you:

• Run workflows downloaded from untrusted sources
• Execute commands or scans against targets you don't own or have permission to test
• Use workflows without reviewing their contents first

You are responsible for what you run. Always review workflow YAML files before execution, especially those obtained from third parties.

Osmedeus is made with ♥ by @j3ssie and it is released under the MIT license.
