Built for developers,
by a developer
FavTray is a macOS menu bar application that bundles seven developer-specific tools into a single icon: eye rest timer, AI cost tracker, window manager, port kill, system info, cloud costs, and keep-alive. Every tool is chosen for the way developers actually work.
How FavTray fits into your workflow
Morning standup
Quick glance at CPU and memory before you start. Yesterday's Docker containers are still running and eating 4GB of RAM. You spot it before your IDE starts lagging.
Start coding
FavTray starts your 20-20-20 timer automatically. It detects your typing and waits until you pause before suggesting a break. No interruptions mid-thought.
Port conflict
You start your dev server but port 3000 is taken. Open Port Kill, find the stale process from yesterday, kill it in one click. Back to coding in 5 seconds.
Multi-window workflow
Editor on the left half, terminal on the right. Quick keyboard shortcut and your windows snap into place. No dragging, no manual resizing.
AI-assisted debugging
Deep in a Claude Code session. FavTray shows $3.42 in the menu bar for this session. You notice you have spent more than usual and switch to a cheaper model for the remaining fixes.
Team call
FavTray detects your Zoom call and automatically pauses break reminders. When the call ends, it resumes your timer right where you left off.
Deployment check
Before heading out, you glance at today's AWS + GCP spend. $12.45 combined. The new Lambda function is not spiking costs. Good to go.
Stepping away
You need to step away for 30 minutes but want Slack to show you as active while your long CI build runs. Toggle keep-alive on, set a 1-hour timeout. It pauses automatically when you come back.

Frequently asked questions
Is FavTray built for developers specifically?
Yes. Every tool in FavTray is chosen for the developer workflow: AI cost tracking for Claude and OpenAI, port management for dev servers, window snapping for code + terminal layouts, and system monitoring for build performance. It is not a generic utility — it is a developer toolkit.
How much does FavTray cost for developers?
Two tools are free forever (Eye Rest Timer and Port Kill). Pro costs $20 for 6 months ($3.33/month) and includes all 7 tools. 14-day free trial, no credit card.
Does it work with my existing tools?
Yes. FavTray reads Claude logs from ~/.claude/, uses existing AWS and gcloud credentials, detects Zoom/Slack/Teams for smart pauses, and works alongside any IDE. No configuration needed.
Will it slow down my Mac?
No. FavTray uses minimal resources. System Info only collects stats when the popover is open. Keep Alive uses tiny mouse movements. Eye Rest runs a lightweight timer. Disabled tools use zero CPU.
Can I use it on my work and personal Mac?
The Personal plan covers 1 Mac. The Team plan covers up to 3 Macs for $35/6 months — great for developers with a work machine and a personal laptop.
