Claude Code Prefers Building Tools Over Buying Them

📝 What Claude Code Actually Chooses This week a fascinating report came out. But the most important finding in @edwin's research is the one nobody is talking about. And it's not the tool rankings. Build vs. Buy The report tracked 2,073 tool picks across 20 categories. Custom/DIY appeared in 12 categories with 252 total picks. More than any single product. Claude's default instinct isn't "use PostHog or LaunchDarkly." It's "I'll just build Feature Flags myself." Winners today. Losers tomorrow The other finding nobody is connecting: Prisma went from 79% to 0% between model versions Redis from 93% to 29% These look less like preference shifts and more like extinction events. Not because the product got worse, but because the training data shifted. LLMs have Recency Bias Newer models seem to favor newer tools. The implication is wild: your adoption curve now has to outrun the model retraining cycle. If you're not generating fresh content, you're fading from the AI's memory. But if you keep shipping, the same cycle works in your favor. The Growth is Real At @resend we're seeing this firsthand. Claude Code recommends us 62.7% of the time for email. Our internal data shows that, of the people who say where they found Resend, 1 in 4 say Claude. This doesn't translate to just new sign ups. It translates to actual revenue. But we're not taking this for granted. The same dynamics that put you on top can take you out if you stop shipping. Takeaways The blank-canvas moment is your new distribution channel. Invest in it. Don't confuse a snapshot for a moat. Today's default can become tomorrow's forgotten. The best defense is still the same: build something developers love. http://x.com/i/article/20274222271974686…
