Process
From zero to merged PR in three simple steps.
Filter by stack, YC batch, or contribution area. See GitHub activity, past sessions, and reviews before you book.
Pick a time that works for you and pay per session — no subscriptions, no commitments. Cancel before start for a full refund.
Live screen-share on an actual open-source PR. Merge code into repos that people use and grow your GitHub profile doing it.
Why Codraft
Every other mentorship platform gives you a talking head and a todo app. We give you a pull request with your name on it.
Every session ends with code merged into a real repo. No contrived exercises — your GitHub profile shows exactly what you've shipped.
Our engineers came from YC startups that raised real rounds, scaled real products, and yes — some failed. That experience is exactly what you need.
No monthly subscriptions. No platform lock-in. Book one session or twenty — you pay when you show up, and only then.
Social Proof
“I shipped my first open-source PR to a real React library in my second Codraft session. The mentor caught three bugs I would've spent weeks tracking down on my own.”

“Finally a platform where I can mentor juniors on real-world problems. No contrived exercises — just actual production code and the kind of messy, interesting challenges I love.”
Sarah R.
Senior Engineer · YC W22
“Three sessions in and I understand React internals way better than from any tutorial. Watching someone with 10 years of experience debug live in a production context is priceless.”
