在Replit上构建一个以隐私为首要考虑的文件转换网页应用
Build a privacy-first file conversion web app on Replit
一位用户构建并发布了工具保险库，一个基于Replit的文件转换网页应用，使用FastAPI和Tailwind，至今花费约34美元。
做了什么
They built Tools Vault on Replit with FastAPI and Tailwind, hosting everything there and designing it so file conversions run entirely in RAM and are deleted right away, while sessions live in PostgreSQL for seven days. In comments, they said they first used Grok to draft a detailed master prompt, iterated on the concept outside Replit, then used Replit to implement and make targeted app changes once the requirements were clear.
效果如何
The app was shipped as a live privacy-first file conversion web app, and the builder said total cost so far was $34. They did not share usage or revenue numbers, and commenters challenged both the marketing tone and the app’s security.
值得注意
Their main cost-control tip was to avoid lots of back-and-forth prompting in Replit and do exploration or pivots in cheaper models first.
试试这个 Prompt
Build a privacy-first file conversion web app for [file types, e.g. PNG to JPG and PDF to text] using FastAPI and Tailwind. Process files in memory or delete them right after conversion, and never store or log user uploads. When conversions work and the app is deployed, give me the live URL and a short summary of the privacy approach and the estimated hosting cost.
