There are plenty of ways to get a planter attached to a railing or a fence.. but I have a solid, slightly sloping, concrete window sill outside my kitchen window. It would be great to put some herbs in a pot there.. but how do I secure the planter. I've looked everywhere but can't find anything.
Once filled with soil, the planter will become much heavier and much less likely to fall. But I can see how the slope of the ledge could be an issue. One thing you could try to do, to make the planter sit more evenly, is to boost up only the one side of it with something underneath, so that it will be more level and not 'follow' the slope of the ledge.
To secure the planter, you could try something like magnet tape and metal tape. So along the window ledge, you could lay one or two strips of metal tape and then attach the magnet tape to the bottom of the planter. I bought some of both recently on amazon.de.

I'm not sure if the adhesive would stick well to concrete, though.
You could try Hornbach

or search for Balkon Blumentrog Halterung
maybe post a picture of your balcony?
What floor, and what's underneath? If it did fall off would it be annoying or a potential serious accident?
If not dangerous I think getting the level with strips of wood and relying on the weight of the planter should be fine. Have it tilting slightly towards the window would make it a bit more secure.
Don't use one long bit of wood - you don't want water pooling behind it. Also a thinner non-continuous bit will have more pressure on it and therefore is less likely to slip.
Wind in your area could be a problem, it certainly is around here.

I'd second Tom's concerns. Many moons ago I'd put a couple of small pots of seedlings onto my kitchen windowsill, inside a shallow wooden box, and (I thought) securely attached the box to a radiator underneath the kitchen window as there was no railing or other place to tie things onto. After a particularly bad wind storm the box and pots were found on the glass roof of the porch several storeys below, my precious seedlings had disappeared.... and I got a nice bill for the replacement of the glass canopy. It's also against the bylaws of many communes to place planters on the outside of window guards rails, in case they fall onto the heads of people below.
Certainly it's a very bad idea to try this if you're not on the ground floor. But if you are on the ground floor, the suggestions about wedging the planter so that it slopes towards the window should work.
Yes, don't use a wooden or light plastic planter - use one of the heavy Eternit ones or similar.
Of course if you own the property you have more options, like screwing a bracket to the windowsill.
Thanks as always ...
It's a ground floor flat but the idea is to just open the kitchen window and pluck some fresh herbs.. (as opposed to.. you know..the tiresome business of putting on footware and walking out into the garden )
Those brackets on the Hornbach site might be the thing I've been looking for..
(Being in the Basel Borderlands I only associate Hornbach with Germany.. and I can't get over there for now)
You can order them from hornbach.ch and have them delivered. Jumbo, Bau & Hobby, Bauhaus, Obi and Brack will have similar, and they all deliver.
This...ipoddle,I have several Eternit planters in the cellar. If only you could pick them up, I'd be glad to give them away!! Aggggggg...covid, drat!
Yes, the heavier the better.
That way, if it does fall on someone's head, there's no way they are going to be able to complain and report you.
No drilling involved, just place it in front of the planter.
