I have set up a website dedicated to crafters in the Elder Scrolls Online, called Masters of Craft at https://mastersofcraft.info. The site provides several tools for crafters:

The Master Writs Module
In the Master Writs module, you can keep track of all the master writs your characters have in stock. This provides you with a way of keeping track of all the master writs you still need to craft which allows you to craft all items for multiple master writs in one go, then travel to the master writs merchant where you can start each master writ quest and immediately turn in the crafted item. This is way faster than having to travel back and forth between the crafting stations and the master writ merchant. It also allows you to start an experience scroll or experience potions to gain more XP from the master writs quickly. The module also provides additional support for alchemy writs and enchanting writs, as it shows which ingredient combinations (alchemy) or runes combinations (enchanting) create the requested item.



The Motifs Module
In the Motifs module, you can keep track of which motifs your characters have already learned and which you still need to find. The learned motifs are also linked to the Master Writs Module so you can see with master writs you can and which you cannot yet craft. You can also keep track of your stock of tradeable motif pages and which character (or banker or storage chest) has them. An upcoming update, will provide means to search for other players with whom you might be able to trade motif pages based on what you both need and both have in stock.



Guild House Map Hosting
You can host interactive maps of your own in-game house with locations to set craftings stations and other services, like mundus stones, training dummies etc., that your house provides. You can give other players access to these maps they can see where to find the services in your house. There is a link from the master writs module to the location of set crafting stations in houses and writs can be sorted based on the location in a house. This can make it even more efficient to craft multiple equipment master writs by providing an optimal route. For several in-game houses, we already provide stock maps to use, for other houses you can upload your own designed map images. Defining locations and what can be found at these locations can all be done on the site with easy to use tools.



Daily Crafting Calculator
A tool to calculate how many items you have to craft for daily crafting writs if you want to craft them a few days in advance.

Alchemy Calculator
A tool to find out which ingredient combinations result in a potion/poison with the one, two or three effects you select. Or combine two or three ingredients to see what effects they provide in a potion or poison.

Multiple Character Support
You can define multiple characters on the site and keep track of master writs and motifs for all your characters.

Basic Guild Support
The site also offers some basic guild support, so you can give other members of your guilds access to your guild house maps.

As I am a crafter in ESO myself, I started setting this up and decided to make it freely available for fellow ESO crafters to use (and I don't use advertisements or share any of your data with other parties).

You can find the website at mastersofcraft.info

The site has been designed to work on PC/Mac, tablets and mobile devices (except for the location editor which works best on larger displays).

Here are a couple of more screenshots to give you an impression of the site:
