Zenfyle: PDF Toolkit SaaS (Full Source Code)

About

I have been building software for a long time, and I will tell you straight what this is and what it is not.Zenfyle is a complete PDF toolkit, the kind of product people pay Smallpdf and iLovePDF for every month. Twenty-eight tools. Every one works. I tested each of them start to finish and recorded the whole thing on video, so you can watch it run before you spend a minute talking to me: https://www.youtube.com/watch?v=liNVgC1ZZF0WHAT IS IN THE BOXMerge, split, rotate, reorder, remove and extract pages. PDF to and from Word, Excel and PowerPoint. PDF to JPG and PNG, and back again. Compress PDFs and images. Page numbers, watermarks, annotation, signatures, form filling. Password protect and unlock. Real redaction, where the hidden text is actually destroyed and not just covered with a black rectangle. Document compare. OCR for scanned files.HOW IT IS BUILTI have seen too many projects that look fine and fall apart the first time someone touches them. This one is put together properly.- Simple jobs run in the visitor's own browser. Fast, private, and they cost you nothing to serve.- Heavy jobs go to a real background queue (BullMQ and Redis) and are handled by LibreOffice, Ghostscript, qpdf and Tesseract.- Every engine sits behind its own adapter. If you want to replace one someday, you change one file, not forty.- Passwords never touch the database. Download links are signed and expire. Uploaded files are deleted after two hours.- One tool registry drives the menu, the pages and the search. Tool number twenty-nine is an afternoon's work.A REAL APPLICATION, NOT A DEMOUser accounts, login and password reset, and a dashboard with job history. An admin panel with soft delete, restore and a full audit log. Daily usage limits already built in. Next.js 16, React 19, strict TypeScript, Tailwind 4, Prisma and Postgres, Auth.js 5. Forty-three automated tests pass, lint is clean and the production build passes. A written specification and a progress log are included, so whoever takes this over is never left guessing.CONTAINERIZED AND READY TO DEPLOYThis ships as a Docker project, not a folder of loose files. A Dockerfile and a Docker Compose file are included. One command starts the whole stack: docker compose up -dThat brings up the web app, the background worker, Postgres and Redis together. Database migrations run on their own on first start. The image already contains the heavy software the server tools need (Ghostscript, LibreOffice, qpdf, Tesseract), so you install none of it by hand. It runs as a non-root user with health checks on every service.Going to production is a matter of settings, not rewrites. Set your environment variables and point it at your own services: Postgres on Supabase or Neon, Redis on Upstash, file storage on Supabase, and any SMTP provider for mail. A Docker guide covers variables, volumes, backups and troubleshooting. Any VPS or container host that runs Docker will do. One honest note: a serverless-only platform will not run the heavy tools, because they use real system software.WHAT YOU GETThe full source code in a private repository, transferred to you. The Zenfyle name and branding. The demo video. Two weeks of my time after the sale to get you running. The sale is exclusive: one buyer, and then it is yours alone.WHAT YOU DO NOT GETNo domain, no hosting, no live site. And no traffic, no users and no revenue, because it has never been launched. You are buying a finished product and a long head start, not an established business. I would rather you hear that from me now than discover it later.WHAT A CAREFUL BUYER SHOULD KNOW- Ghostscript is AGPL-licensed. It runs as a separate program behind an adapter, and the repository documents how. If you want complete certainty, Artifex sells a commercial licence.- The project was built with AI coding assistance. I will assign every right I hold to you in writing.- A short list of known npm audit findings is in the README.- Converting out of PDF is approximate by nature. PDF to Word recovers the text but not the exact layout. Going to PDF from Word, Excel or PowerPoint is high fidelity.WHY THE PRICE IS FAIRRebuilding this from nothing is hundreds of hours of skilled work, and that is before you spend a week on the document engines. At ordinary freelance rates, you would pay several times what I am asking. You are paying for a finished, tested, documented product and the months you will not spend building it.HOW WE DO THISYou ask your questions. I send a short NDA. Once it is signed, I walk you through the running project on a call. We agree the price in writing, with a clear list of what is included. Payment is by bank wire or a similar traceable transfer, with a small deposit to start and the balance before handover. I transfer the repository as soon as the funds have cleared. No surprises on either side.Price: $3,500, exclusive, one time. If you have a serious proposal, send me a message and tell me what you plan to build with it. I answer every serious offer.
