Hey everyone,
A couple weeks ago I shared how I built LastSend entirely on n8n (40+ workflows, Google Play Billing, media processing, the whole thing).
But I want to share something that happened right after.
On February 19, I published my build story here. On February 21, just 48 hours later, the domain lastwithyou(dot)com was registered. By February 23, they had a live site with the same concept: posthumous message delivery with text, photos, videos, voice recordings, and a check-in dead man’s switch system.
The site is run by a Korean web agency called Webworks (webworks.co.kr). No named founder, no social media presence, no mobile app. Their support email is literally their domain registrar catch-all ([email protected]). They’ve since published dozens of AI-generated blog posts.
I’m not posting this to complain. I knew building in public had risks. But I want other builders here to be aware: when you share detailed build stories with architecture breakdowns, someone might use that as a blueprint. The n8n community post gave them the concept, the feature list, and the confidence that the idea works.
A few things I’ve learned from this:
-
Get your SEO up before you share publicly. I had zero blog content on lastsend.app when I posted here. That was a mistake.
-
Your moat is what they can’t copy. For me that’s the native mobile app, the trusted contact verification system, and the fact that I actually care about the people using this product.
-
Building in public is still worth it. The connections and feedback have been more valuable than what the copycat can take.
If anyone else has dealt with this, I’d love to hear how you handled it.
