Activity Monitor lists a thousand processes, a hundred of them called Google Chrome Helper. Vitals adds every helper to the app that launched it, so you see 60 apps instead of 1,000 processes, each with one figure for memory, CPU, energy, disk and network. It keeps 30 days of history, alerts you when an app misbehaves, finds forgotten dev servers, and shows temperatures, fans and battery. Every readout can sit in your menu bar, arranged your way. Pay once. No subscription, no account.

VibeDefend installs on your AI coding agent (Claude Code, Cursor, Windsurf, Copilot, Codex and more) with one command. From then on the agent writes with your business rules, mined from your repo, and your security rules in its context. It scans each diff while the file is still open, and a guard refuses rm -rf, sudo or a read of your secrets before it runs. Scanners check code after the commit, this runs before the line is written. Free plan, no card.
