The Story

I'm a solo founder in Chicago. I built 250+ free tools using AI — primarily Claude — and deployed them all to spunk.codes with zero VC funding.

No team. No investors. No paywall. Just one person proving that AI lets solo creators ship at a scale that used to require entire engineering teams.

The tools are free because I believe the best developer tools should be accessible to everyone. The site makes money through ads and affiliates — not by charging developers.

SPUNK.CODES is part of a 170+ site network all operated under SPUNK LLC, covering everything from crypto to music production to home services.

Maker Comment

Hey Product Hunt! I'm the solo founder behind SPUNK.CODES. I built 250+ free developer tools using AI (primarily Claude) — all by myself, no team, no VC money. Why free? Because I've been frustrated by tools that make you create accounts, verify emails, and then hit you with a paywall after 3 uses. Every tool on SPUNK.CODES works instantly with zero friction. Some highlights: - JSON Formatter, API Tester, Regex Tester for devs - Meta Tag Generator, Keyword Density Checker for SEO - Password Generator, JWT Decoder for security - Invoice Generator, Pitch Deck Builder for business - 32 free ebooks on topics like Vibe Coding and AI Automation The site is part of a 170+ site network I operate under SPUNK LLC — covering crypto (coincould.com), music production (musichog.com), home services (fencejob.com), and more. I'd love your feedback — what tool do you wish existed? I'll build it this week. Thanks for checking it out!

LinkedIn Post

I just launched SPUNK.CODES on Product Hunt. 250+ free developer tools. Built entirely by one person using AI. No signup required. No paywall. No email gates. Here's what I learned building 250+ tools as a solo founder: 1. AI makes solo scaling possible. What used to require a team of 10 engineers, I did alone with Claude AI. 2. Free tools win. The best way to build an audience is to give massive value upfront. Zero friction = maximum adoption. 3. You don't need VC money. SPUNK LLC operates 170+ websites with zero outside funding. Revenue comes from ads and affiliates. 4. Ship fast, ship often. I added 45 new tools in a single week. AI lets you iterate at speeds that weren't possible even a year ago. The tools cover: JSON formatting, API testing, SEO analysis, password generation, code playgrounds, regex testing, invoice creation, and 240+ more.
