Calendly wouldn't sync two emails for free, so ZazenCodes built a scheduler from a phone
Calendly wouldn't let ZazenCodes sync two email accounts for free, so they built their own in about three hours. The first prompt went out from a phone on a walk in the park, and the build finished from the couch in front of the TV, while Codex worked on a laptop sitting on the lock screen. It used the gcloud CLI and Chrome to set up Google Cloud, deployed to Cloudflare on a subdomain and even created the DNS records. 'RIP SaaS,' they say. Calendly charged for a second email. The zombie charged for a stroll.
Calendly wouldn’t let me sync 2 emails for free
So I built my own
It took about 3 hours
I kicked off the first prompt from my phone, as I walked in the park
And finished it from my phone on the couch watching TV
It ran on my laptop which was open (on the lock screen) on my desk.
Codex used the gcloud cli and chrome use to setup whatever it needed in GCP
I told it in the initial prompt to use a subdomain on zazencodes dot com, and deploy to cloudflare
It setup whatever DNS records it needed as well, using my logged in cloudflare account in chrome (Wrangler cli does not let you do DNS)
Long live entrepreneurship with lower barriers
And RIP SaaS
