I've set up a project template that lets you assemble Apple II programs
on a modern computer using Merlin32.
It automatically injects the resulting binaries into a disk image via
AppleCommander, and then launches on the Will Scullin's web based emulator.
The emulator linked in the project is a fork, where I've made a few
modifications to improve its graphical capabilities - handy for testing
different video modes like Composite, RGB and video card displays.
There is also an option to launch AppleWin, since the web emulator doesn't
quite handle the more timing sensitive stuff like Vapor Lock,
although the AppleWin integration doesn't yet support live-reload.
