What It Is
Imagine a co-pilot for ethical hackers and penetration testers. Nebula is a desktop application that consolidates all the tools a security professional needs—terminal, code editor, browser, notes, and an AI assistant—into one interface.
This matters because it streamlines the often-fragmented process of a security engagement, from initial investigation to final reporting. It helps reduce repetitive manual work, ensures a clear audit trail, and lets human operators focus on critical thinking, not context switching.

How to Use It
Nebula is currently a Linux x86_64 desktop application primarily installed via an APT repository. It requires Docker or Podman for its terminal and automation features. The first launch may involve downloading a Kali image.
Prerequisites:
- Linux x86_64
- Docker or Podman
- Internet connection
Estimated setup time: 15 minutes.
sudo apt update
sudo apt install -y ca-certificates curl gnupg
curl -fsSL https://berylliumsec.github.io/nebula-apt/nebula-archive-keyring.asc | sudo gpg --dearmor -o /usr/share/keyrings/nebula-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/nebula-archive-keyring.gpg] https://berylliumsec.github.io/nebula-apt prerelease main" | sudo tee /etc/apt/sources.list.d/nebula.list >/dev/null
sudo apt update && sudo apt install nebulaWhat I'd Build With This
Automated Recon & Report Generator for Freelance Pentesters (micro-saas)
Freelance pentesters spend significant time on repetitive reconnaissance and report formatting. Build a cloud service wrapping Nebula that automates initial scans, organizes findings, and generates professional, customizable reports. Pentesters upload scope, get structured output, and save hours. Target them via cybersecurity communities and LinkedIn.
Effort: 1 Month Build Time · Target: Freelance Pentesters, Small Security Consultancies · Pricing: $79/month
Managed AI Pentesting Platform for SMBs (saas)
Small to medium businesses often lack dedicated security teams or budget for expensive external pentests. Offer Nebula as a managed cloud platform, providing a guided, AI-assisted environment for their IT staff to perform internal security assessments. This reduces reliance on consultants and improves internal security posture. Market through B2B tech platforms and direct sales.
Effort: 4 Months Build Time · Target: SMB IT Departments, Mid-Market Security Teams · Pricing: $399 - $1499/month
Customizable Internal Red Team Workbench (enterprise)
Large enterprises require highly controlled and auditable security tools for their internal red teams. Provide an on-premise or private cloud deployment of Nebula, deeply integrated with their existing SIEMs, vulnerability management systems, and compliance frameworks. Offer professional services for custom module development, training, and ongoing support. Target via direct enterprise sales and security conferences.
Effort: 6-12 Months (initial deployment & integration) · Target: Large Enterprise Security Teams, Government Agencies · Pricing: $75k - $300k+ annually
Sai Pavan Gopularam's Take
Nebula is a seriously impressive tool that brings AI to the often-manual world of pentesting. I see a clear path to building a multi-tenant SaaS platform for small security teams, automating their initial recon and reporting. I bet a well-executed version of that could hit $50k MRR within 18 months.
Watch Out For
- Linux Only (Currently): Nebula 3.x is currently only available for Linux x86_64. macOS, Windows, and ARM-based Linux systems are not supported in the current release candidate.
- Container Runtime Required: Core terminal and automation features rely on Docker or Podman. Ensure one of these container runtimes is installed and properly configured on your system.
- Preview Build: This is a preview release (alpha.5). Expect potential bugs, breaking changes, and ensure you back up engagement data before use. It's not yet production-ready.
- Initial Download Time: The first launch of Nebula may take several minutes as it needs to download and prepare the official Kali Linux container image, depending on your internet speed.
