About
For the moment the app works, and is yours to run
AI tools can produce a working app in an afternoon. Running it is another job: deploying, undoing a bad change, renewing certificates, keeping backups, watching the bill, answering for the data. Keelmark is a short course on that job, with an exam at the end and a certificate of completion for those who pass.
How the course is made
The lessons were drafted with help from an AI model, then checked against the documentation each lesson links: MDN, the Git and npm documentation, Let’s Encrypt, the US Copyright Office, the FTC, the W3C and others. Every lesson shows the date its sources were checked. No AI runs on the site: grading is plain code comparing your answer with the right one.
What the certificate means
It is a certificate of completion for this course: all eighteen lesson checks passed and the final exam passed, with the score printed. It is not a professional certification, not an accredited credential, not an industry certification and not a licence. The exam is unsupervised. The certificate and its check page say all of this, so nobody reading it is misled.
Who runs it
Keelmark is built and run by WeldonPC.com, a computer and web services company in Northeast Ohio. Once checkout opens it will be paid for mainly by the people who use it; until then the exam and certificate are free. The public reading pages also carry one banner ad from AdEngine, WeldonPC.com’s own small ad network (see Privacy). It does not sell or share anyone’s data.
The name
A keel keeps a boat upright when the wind pushes. The course is meant to do the same for the apps you build. Keelmark is not connected with any company that uses “vibe code” or “certified” in its name; vibecodecertified.com is simply the address.
