#13777 ESP-01 modules are dirty cheap these days. You can find them at < $3 in single quantity.

Unfortunately, the most common ESP-01 module is not really breadboard friendly: its dual row connector is such that there is no way you can plug it into a standard breadboard directly.

Of course, makers are not really stopped by this kind of details, and it didn't take long before some among them came with more or less interesting solutions to this problem.

As opposed to all adapters I have found so far, mine doesn't require to make a PCB, only standard easy to find parts and tools are required. It doesn’t take long to build and does not require any special skills either…

Easy, quick and cheap HOWTO:
