Here's what you'll find in this issue:

• This founder productized an internal agency tool to $500k ARR instead of going full-time services.
• 5 vibe coding tools. Some of the latest apps for coding with AI.
• Yesterday's build board winners, including three new product launches from indie hackers.
• 30-second growth tip: Build your own search index from stuff that's already public.

Justworks handles HR, payroll, and benefits complexity, so you can focus on building your small business.

Arjun Jain built an internal tool for his dev agency, used it for years, then spun it out into pre․dev. Eight months later it's at ~$500k ARR, with 10,000+ founders having tried it and hundreds of agencies using it on real client work. That last part is the signal I pay attention to.

pre․dev's angle is that the bottleneck is planning (not code generation). The product turns “what should we build?” into a structured architecture and milestone plan first, then executes task-by-task with verification before anything touches your repo. It's basically trying to be an autonomous engineer.

Arjun gets into how he shipped the first version in 36 days, chose product over services, landed agencies early, and much more. Check out the full interview below!

Build your own search index from stuff that's already public.

Devv didn't create original content. They crawled GitHub repos, official documentation, and developer forums, then built a custom search index on top of it. All public information, just organized specifically for coders.

Why bother when Google exists? Because Google serves everyone. (Or at least it will until AI search takes over everything…)

A niche index serves your people better. Devv's search knows what developers actually need, so it surfaces relevant answers faster and with fewer hallucinations. This is tedious, unglamorous work, but that's exactly why it's defensible. Your competitors want to ship features, not spend months crawling and indexing boring documentation. Most will never bother.

A guy I know who's a huge a-hole sent me this tweet. So… maybe don't completely edit who you are, but a little spellcheck probably won't hurt. 🙃
