Note that while the 555 is definitely a classic, definitely an amazing and useful chip, it puts large current spikes on the power supply and you would probably want to use something else in new designs unless you’re feeling nostalgic.
What’s the alternative? Is the Ne555 or is there better?
This was the first IC I ever saw, when I was pulling apart busted electronics equipment in the early 1970s. I understood why transistors had three leads, but what the heck could possibly need eight leads?!?!?

Replacing a 555 timer is a very common job for this type of part. It will typically have an internal oscillator, so it won't need the additional components the 555 needs, reducing cost further. Even if you use something more expensive like an ATtiny (cut down version of the microcontroller found in Arduinos, so very easy to develop for) it might still be competitive because of the reduced parts count and board space.
Earlier quoted context omitted.

There are many better alternatives now.
