Hacker Sidekick is a desktop application that gives penetration testers, red teamers, blue teamers, and security engineers an AI environment purpose-built for cybersecurity work. Built on a VS Code-based interface, it combines an AI model fine-tuned for security contexts with agentic execution โ€” meaning it chains tools together and runs multi-step workflows rather than just providing advice.

Sovereign AI Unlike general-purpose AI assistants, Hacker Sidekick's models are built for cybersecurity work. The AI generates exploit code, analyzes malware samples, writes attack narratives, and works with offensive security terminology natively โ€” without the content restrictions that block legitimate security research.

Agentic Execution Hacker Sidekick executes workflows rather than just chatting. It chains tools like Nmap, vulnerability scanners, and custom scripts into automated pipelines, maintains context across an entire engagement, accesses the terminal on your machine, and produces structured output including reports and documentation.

Local-First Architecture Runs on Windows, macOS, and Linux. Integrates with tools already on your system โ€” Kali Linux, Burp Suite, WSL, Metasploit, and custom scripts. Data stays on your machine by default.

Use Cases Offensive: penetration testing, web application assessment, code analysis, threat emulation (MITRE ATT&CK), bug bounty reconnaissance. Defensive: alert triage, detection engineering, threat hunting, incident response, compliance reporting.

Deployment Individual download (free tier available), team deployment via SSO, and on-premises enterprise deployment with centralized management.

OptMsg is a private, opt-in email service built for people and families โ€” not businesses.

Unlike free inboxes that let anyone reach you, flood you with spam, and profit from your data, OptMsg puts you in control: only senders you approve can message you, and everything else goes straight to Trash. There's no spam to sort and nothing dangerous to click.

Why people switch to OptMsg:

  • Opt-in inbox โ€” only approved senders get through, thanks to a patent-pending opt-in router
  • Passwordless sign-in โ€” no password to steal and nothing to phish
  • No ads โ€” and your data is never sold
  • A clean inbox โ€” no junk to flag, filter, or delete
  • 15GB storage on paid plans, plus Community Recommendations to help vouch for safe senders
  • Full encryption when both people use OptMsg

OptMsg runs on the web, iOS, and Android. Start free with the Reader plan, or upgrade from $49.99/year.
