Dungeon Map Doodler - online mapmaker. Very basic, but it features all the tools required to draw a decent map quickly.
Ye Olde Mapmaker (now defunct) was quite an unique thing. It was mobile mapmaking application, that didn't suck. It wasn't the pinnacle of design, but it allowed to sketch a useful map quickly.
Character sheets by Mad Irishman - dated, but still useful collection.
Campfire - one of most powerful worldbuilding applications. It has plenty of modules, maps, characters, encyclopedia, story arcs. It's amazing.
Dundjinni - back in the days, this was quite useful, fun to work with, albeit a bit crude mapmaker. Now the website is gone, the software no longer legally available...
AAR-Kelaan - this is one of the first modern pieces of hexmapping software. It is dated, needs a little tinkering to run, but the effect is worth it.
ProFantasy - for years, this was the best mapmaking suite the money could buy. It features a handful of focused applications (city designer, campaign cartographer).
Grid Cartographer - relatively unknown but quite powerful, easy to use and original mapmaker (it features visualization of the map made)
Map Forge - mapmaker made by Battlegrounds developers. It boasts high compatibility with popular VTTs and is quite easy to use.
Battlegrounds - not as famous and massive as the most popular VTTs out there, but it still works and is still capable of delivering fun.
2 Minute Tabletop - collection of free/1$ worth battlemaps. Please check the more expensive ones too - lots of good stuff there.
Tom Cartos - library of maps, tokens. Fantasy and modern styles available, plenty of free content.
Lost Gaymer - massive collection of battlemaps. Grid/no-grid, free/commercial versions available.
Chaos Gen - fantasy generators with text output (5 room dungeon is very interesting)
Cosmic Peril Generators - dozens of generators. They provide short descriptions as the result, but they are quite useful nevertheless.
Box full of Boxes - a bunch of random tables. Well think through content, if I may say so.
Polygon map generator - quite a handy map generator, with a few variables to toy with
Tangrams Tron Style - a map of the world presented in Tron-like fashion. Perfect for cyberpunk or SF games.
Deepnight - free, standalone and browser-based floorplaner, that works best for modern and SF settings.
Other World Mapper - offline mapmaker sporting quite a massive library of assets. It's not as easy as Inkarnate, but offers similar experience and deliver no worse results.
