Making a textboard

Did you ever make one? Which frameworks did (or would) you use? Did you program any unique features? Do you host it?

I don't get how C is supposed to be unsafe. Just use pledge(2) and unveil(2), mever use unsafe functions like strcpy and run it through a static analysis to find potential bugs. Optionally stick to a very secure standard/style. Very unlikely to still have any vulnerabilities right?
