The link in the browser's address bar always describes to the currently planned route - you can simply save it as a bookmark or share it.
In the upper left corner you can select different profiles (trekking, mountain bike, racing bike etc.). Furthermore, three alternatives are planned for each route, which can also be selected in this menu.
Round trips can be planned by placing the final point a little bit next to the startpoint (watch out: if you click exactly on the startpoint, it will be deleted).
The profiles can be adjusted directly in BRouter-Web (change priorities for certain street types etc.) - after clicking on "Upload" they are used for routing immediately. Attention: the modified profiles are not permanently available. You should copy and save them if necessary. You can paste them into the edit field next time.
In the upper right corner of the map you can select different map views (OpenStreetMap Mapnik style, OpenTopoMap and many more)
Also in the upper right corner there is a button with a table icon, which shows details about the road conditions etc. for each individual route section.
The pie chart icon opens a statistical breakdown of road types, pavement and way conditions. This function is only available on the BRouter instance at https://bikerouter.de/currently (May 2020), but will hopefully be included in the official BRouter-Web source code soon.
At the bottom right there is a button to display the elevation profile. If you move the mouse pointer over the elevation profile, you can see the corresponding position at the top of the map view.
You can load GPX tracks into BRouter-Web via the “Load” button.
VeloViewer Explorer Max Square fans watch out: The VeloViewer KML file can be easily imported into the BRouter using the "Load" function - it couldn't be easier to plan new routes for “ticking of the tiles” (described here: BRouter and the Explorer Max Square)
“Export” creates the route in various formats, which can then be imported into e.g. Garmin Connect, to load it onto a GPS device.
If you want to exclude certain areas for a route (e.g. a road with a bad surface), you can define so-called "no-go areas". These are circles through which the BRouter will not lay a route. These areas are also stored in the link in the address bar - so you can create no-go areas in the vicinity once and then save a bookmark and always start the routing with a predefined list of blocked areas.
Currently (June 2020), the data for route calculation is taken directly from the latest OpenStreetMap raw data four times a day - so changes to OpenStreetMap arrive are available in BRouter very quickly.
If you want to view the map directly under the route, you can set the opacity of the route with the slider on the left side of the screen. Tap and hold the M key for a quick view: As long as the M key is pressed, the route is invisible; if the button is released, the route reappears immediately.
