云服务定价，专治看不懂
Cloud pricing, decoded
云厂商的定价页面，就是不让你看懂
选完服务、上线项目，账单出来一脸懵

向量数据库、VPS、图片生成、支付
鉴权
全是独立开发者真正在吵的那类账单

六类工具，砍到最刚需
Six categories that matter
LLM tokens、向量数据库
VPS、图片生成、支付
鉴权——六个分类，不多不少
每个背后都是独立开发团队真金白银踩过的坑
不是罗列所有云服务
而是只做大家真正在吵的那些
Six categories — LLM tokens, vector DBs, VPS
image gen, payments, auth. Not every cloud service
just the ones indie teams actually argue about
That's a product decision

数据不离开浏览器
Nothing leaves your browser
12 个工具全部客户端运行
你输入的任何数字都不会上传
不用注册、不用登录
定价数据每月人工对照官方文档更新——作者自己说这活很枯燥
但这样才值得信
All 12 tools run client-side — nothing you
type leaves the browser. No signup. Pricing is
reviewed monthly against official docs. The author says
it's tedious, but it's the only way to
be trustworthy
作者在帖子里原话：「收到一张 340 美金的意外账单后
我做了这个免费 API 成本计算器」
没有融资故事、没有增长黑客
就是一个人被账单刺痛后动手做了个东西
The author's own words: 'I built a free
API cost calculator after a $340 surprise invoice.'
No growth-hacking, no fundraising story — just one
person getting stung by a bill and shipping
a fix
