Both sit on a developer's machine and that is where the resemblance stops. One evaluates what your coding agent produces, the other explains what your computer is doing. Here is what each actually covers, and which to reach for first.
TL;DR
These two do not compete. VibeDefend installs inside your coding agent, mines your repo for business rules, scans each diff while the file is open and refuses rm -rf, sudo or a raw .env read before the command runs. Vitals is a Mac activity monitor that groups 1,000 processes into 60 apps, keeps 30 days of history and costs $5 once. Install VibeDefend if an AI agent writes code you have to sign off on; install Vitals if your machine's fans are the mystery.
| Feature | VibeDefend by CybeDefend | Vitals |
|---|---|---|
| What it is | AI code-security layer for coding agents | Mac activity monitor |
| Runs inside | Claude Code, Cursor, Windsurf, Copilot, Codex | macOS menu bar app |
| Pricing | Free CLI install, CybeDefend platform tiers above it | $5 one-time launch price, 14-day refund |
| Blocks commands | Yes — rm -rf, sudo, raw secret reads, unsafe deletes | No |
| Rule injection | Business rules mined from your repository | No |
| Security scanning | SAST, SCA, secrets, IaC, CI/CD, MCP servers | No |
| Compliance context | OWASP, SOC 2, GDPR, ISO 27001 in-session | No |
| History | Per-diff findings during the session | 30 days of per-app metrics |
| Coverage area | The code your agent writes | CPU, memory, disk, network, GPU, battery |
| Platform | CLI inside your AI coding agent | Mac, menu bar |
| Offline mode | Scanners run locally against your repo | Native app, works offline |
| Best for | Teams shipping code written by AI agents | Mac users who want to know what is eating the machine |
Pick VibeDefend by CybeDefend if
When the pull request came out of Cursor or Claude Code, a layer that holds your repository's rules and refuses destructive shell commands catches what review alone misses.
Pick Vitals if
Grouping processes by application, keeping a month of history and flagging misbehaviour turns 'the browser is heavy again' into a number worth acting on for the price of a coffee.
No. One evaluates the code your agent writes and the commands it runs; the other measures resource use on your Mac. Installing both is reasonable and they do not interact.
If an AI agent commits into a shared repository, the guard comes first, because a bad diff costs more than a slow laptop. If the machine itself is the daily problem, start with the monitor.
No. VibeDefend plugs into the coding agent rather than the operating system, so it follows Claude Code, Cursor or Copilot wherever they run. Vitals is macOS-only, with Windows on a waitlist.
VibeDefend installs from a free CLI package with CybeDefend's platform tiers behind it. Vitals is $5 once at launch pricing, refundable for 14 days.
