Tools I use daily myself
I'm a marketing consultant with more than ten years of experience in digital marketing. I collect tools here that I needed myself and couldn't find anywhere else — or were hidden behind unnecessary registrations and paid plans.
The goal is to build a quality, open collection of tools that saves time for me and for you.
Privacy first
No accounts, no third-party cookies, no tracking. Everything runs in your browser.
No compromises
Each tool does one thing — and does it well. No paid upgrades for basic features.
Open to everyone
Free for everyone. Advanced features and client tools coming gradually.
