With GSD, I was able to write 250K lines of code in less than a month, without prior knowledge of claude.
That sounds awful.
I got a promotion once for deleting 250K lines of code in less than a month. Now that sounds better
I get it now. Hopefully the utility of it will eventually bring some value. Maybe Utility and corresponding LOC should help you assess my work. Since I didn't share what I have, I can see people getting alarmed at 250K lines of code.
I could copy 250k lines from github.
Faster than using ai. Cheaper. Code is better tested/more secure. I can learn/build with other humans.
This is how I test my code currently.
1. Backend unit tests — fast in-memory tests that run the full suite in ~5 seconds on every save.
2. Full end-to-end tests — automated UI tests that spin up a real cloud server, run through the entire user journey (provision → connect → manage → teardown), and
verify the app behaves correctly on all supported platforms (phone, tablet, desktop).
3. Screenshot regression tests — every E2E run captures named screenshots and diffs them against saved baselines. Any unintended UI change gets caught
automatically.loading story #47419165

I was not a app developer before, but a systems engineer with devops experience. But I learnt a lot about apple development, app store connect and essential became a app developer in a month. I don't think I can learn so quickly with other humans help.

yes vibecoding is fun.
250K? Could you expand your experience with details about your project and the lessons and issues you found?
A self-hosted VPN server manager: a TypeScript/Hono backend that runs on your own VPS, paired with a SwiftUI iOS/macOS app. It lets you provision cloud servers across multiple providers (Hetzner, DigitalOcean, Vultr), manage them via a Tailscale-secured connection with TLS pinning, and control an OpenClaw gateway.
I will open source it soon in few weeks, as I have still complete few more features.

It's important to build a local dev environment that GSD can iterate on. Once I have done that, I just discuss with GSD and few hours later features land.
