[跟风作品] 最近竞价排行榜挺火,我也做了一个,看看能有什么效果 最近看到 Outbid 、WinBid 这类“付费竞价决定排名”的网站,觉得模式挺有意思。 规则简单直接,开发量看起来也可控,所以我跟风做了一个自己的版本: https://bidfight.lol 项目叫 BidFight ,玩法没刻意包装: - 提交产品、网站或个人项目,最低 $1 上榜 - 排名按照 Stripe 实际确认的累计付款金额决定 - 已上榜项目想提高排名,只支付目标金额与当前金额的差额 - 金额相同时,先达到该金额的排在前面 - 点击项目后会先统计次数,再跳转到目标网站 - 榜单、付款金额和点击数据都是真实的,不填充假项目 技术上用了 Vite 、Cloudflare Workers 、D1 和 Stripe 。 目前只有 1 个项目和 $1 的竞价,算是刚把完整流程跑通。这个模式是不是能带来流量、会不会有人愿意付费、榜单最后会变成什么样,我自己也不知道。 发出来主要就是想看看它最终能产生什么效果。 我比较想验证几个问题: 1. 大家会不会

AI CFO for small businesses that shows the math behind financial numbers.
u/Beautiful_Peak6908 · Reddit
I built an AI CFO for small businesses, where tapping any number opens the math behind it. Three App Store submissions later, it's live! My app went live on the App Store this morning after three submissions and I'm still a little wired, so here's the story while it's fresh. For the last while I've been maintaining an open source stats engine called Aurora. Its whole thing is that it measures its own false positive rate and refuses to report findings it can't defend. Very sati

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial."

出海 SaaS/APP 怎么定价?手搓了个沙盘模拟工具 最近在和朋友一起看了下工具类产品的报表 发现有一些持续创收的产品,其实最终看下来,还是倒贴的 因为一开始就自己俩人捣鼓,也不懂专业的财务知识,后面慢慢才发现会存在 gap 值 这一些 gap 值的原因就是各种佣金、消费税和预扣税等等 而且这个和开发者账号主体以及产品推广的地区还都有关系 捋清楚之后,自己也做了这个工具 也希望有专业的小伙伴可以给点宝贵意见哈~ https://trueproceeds.com/
