LED ON and OFF without the SD card support?

I’m trying to dig a bit deeper here as to how I can toggle LEDs if I had just the ESP8266 without the SD card support. As of now. the HTML file we made sits on the SD card of BOLT and is continuously run by it (if I’m not wrong).
can I achieve this without the SD card? what would I use, a standalone web server?

Offcource. Just use Bolt cloud for the same.
