Overview
A user built and shipped Tools Vault, a file conversion web app hosted on Replit with FastAPI and Tailwind, for about $34 so far.
Workflow
Suggested implementation: Build a privacy-first file conversion web app named Tools Vault using Replit, FastAPI, and Tailwind. Design the system to process files entirely in RAM with immediate deletion, while storing session data in PostgreSQL for seven days. Use a cheaper model like Grok to draft a detailed master prompt before using Replit Agent for scaffolding. Human role: Review the generated code to ensure strict adherence to RAM-only processing and correct session retention policies.
Reported result
Actual outcomes are unknown as the source returned an HTTP 403 error and no verified execution data is available. The original case claimed a total cost of $34 and a live app, but these cannot be confirmed. Proposed acceptance check: Deploy a minimal version and verify that no temporary files persist on disk after conversion, and that session data expires exactly after seven days.
Human role

Limitations
Prerequisites include access to Replit, FastAPI, Tailwind, and PostgreSQL. The primary constraint is cost control: avoid extensive back-and-forth prompting in Replit by using cheaper models for initial exploration. Source reliability is low due to the 403 error and lack of verifiable metrics. Human approval is required before deploying any code that handles user files to ensure privacy compliance.
Try it
Act as a senior full-stack developer. I need to build a privacy-first file conversion web app called 'Tools Vault' using Replit, FastAPI, and Tailwind. 1. **Context**: The app must process files entirely in RAM and delete them immediately after conversion. Session data should be stored in PostgreSQL for exactly 7 days. 2. **Inputs**: [Replaceable: List of file types to support, e.g., PDF to PNG, DOCX to TXT]. 3. **Steps**: - First, draft a detailed master prompt using a low-cost model (e.g., Grok) to define the architecture and privacy constraints. - Use this prompt to guide Replit Agent to scaffold the FastAPI backend and Tailwind frontend. - Implement the file conversion logic ensuring no disk writes occur for file content. - Set up PostgreSQL for session management with a 7-day TTL. 4. **Output**: A complete, runnable codebase in Replit. 5. **Quality Check**: Before publishing, run a dry run with a sample file. Verify via logs that the file is never written to disk and is deleted from RAM immediately. Confirm session data expires after 7 days. 6. **Error Handling**: If Replit Agent generates code with disk writes, reject it and refine the prompt to explicitly forbid `open()` or `write()` operations for file content. 7. **Human Confirmation**: I will review the code for security and privacy compliance before deploying to a live environment. Do not spend money on Replit credits without my explicit approval.
