I'm not a big fan of working from home (too many distractions) or co-working spaces (too much commitment, not enough variety), so cafes are usually where I sit down to work every day. I like that my commitment is just the price of a cup of coffee and that I can mix things up a bit every day with a new working space.
But when I get to a new city I'm always starting from scratch figuring out which cafes have fast wifi, power outlets, and an overall work-friendly environment.
Back when I was living in San Francisco, my friends and I made it a point to try and visit every cafe in the city. We kept track of them all in a big shared spreadsheet we called "Cafe Grind".
Once I went nomad, I kept adding cafes to the spreadsheet wherever I went. Eventually the sheet was too big and covered too many cafes to make choices with quickly.
That was the impetus for https://goodworkcafes.com/
Please let me know if you hit any bugs. You can add cafes by clicking the "add cafe" button in the bottom right corner and adding a row to the original spreadsheet which still serves as the backend of the web app.
The website is still in beta, but I hope other nomads here will find it useful too.
