Vibe coding makes launching an app almost free. Running it is another story. I built to calculate your full AI + app stack costs and show which free tier breaks first. Sourced pricing. No signup. No guessing. ->

Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.

Tako's free preview is live: Paste your URL, get a security verdict on your vibe-coded app in 60s. Not an AI wrapper: it fires real requests and PROVES exposure, pulling data from your open DB with no login. Scanning puts you on the early-access waitlist.

Last week I shipped the piece I wish I had started with: five single-ques

有位大兄弟制作了一个计算variational积分价值的网站，使用起来很方便： 我以市值1.5B，总积分9.3M，空投25%来计算，每分的价值是40u，1000分就是40000u 我认为这是保守估计，如果8月份variational上线了swaps和api，数据会更好看，而且以var的格局来看，空投应该不止25%,可能30%以上！

做了一个免费的 Concrete Calculator，帮 DIY 用户估算混凝土用量 最近做了一个英文站：The Concrete Calculator 地址： https://the-concrete-calculator.com 它主要解决一个很具体的问题：用户在做 patio 、shed base 、walkway 、slab 这类小型混凝土项目时，不知道该 买多少混凝土、多少袋，或者该订多少 cubic yards 。 目前支持： - Concrete Slab Calculator - Concrete Pad Calculator - Concrete Yard Calculator - Concrete Bag Calculator - waste factor - cubic yards / cubic feet / cubic meters - 简单材料成本估算 做这个站的原因是我发现很多英文混凝土计算器要么广告太重，要么结果不够直观。这个版本尽量把核心计算和 单
