Replit Filesystem Wiped on Redeploy
Your Replit app stores user uploads, generated files, or cached data on the local filesystem. Everything works fine until you redeploy or the container restarts, at which point all those files are gone. Users report that their uploaded images, documents, or other files have vanished.
Replit's deployment infrastructure uses ephemeral containers. The filesystem is rebuilt from your source code on every deploy, meaning anything written to disk at runtime is temporary. This is a fundamental architecture constraint, not a bug.
This problem becomes critical when your app stores user profile pictures, document uploads, generated reports, or any file that users expect to persist permanently.
Error Messages You Might See
ENOENT: no such file or directory
Error: File not found at /home/runner/uploads/image.png
Cannot read file — path does not exist
404 Not Found for uploaded file URL
Common Causes
- Ephemeral filesystem — Replit deployed containers are rebuilt from source on every deploy
- Files saved to /tmp or project directory — runtime files written to the container's filesystem do not persist
- No cloud storage configured — the app was not set up with S3, Cloudinary, or similar persistent storage
- AI-generated upload code — the AI used simple fs.writeFile() without considering deployment lifecycle
- Cron jobs writing to disk — scheduled tasks generate files that are lost on container restart
How to Fix It
- Use cloud object storage — migrate file storage to AWS S3, Google Cloud Storage, Cloudinary, or Supabase Storage
- Store file references in database — save the cloud URL in your database instead of a local file path
- Use Replit's persistent storage — if available on your plan, use Replit's built-in persistent disk or database for small files
- Convert uploads to base64 in database — for small files like avatars, store them as base64 strings in your database
- Add migration script — create a script that moves existing local files to cloud storage before the next deploy

Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

Full-Stack Software Engineer with 8+ years building high-performance applications for enterprise clients. Shipped production systems at Walmart (4,000+ stores), Cigna (20M+ users), and Arkansas Blue Cross. 5 patents in retail/supply chain tech. Currently focused on AI integrations, automation tools, and TypeScript-first architectures.
Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
Why do my files disappear when I redeploy on Replit?
Replit uses ephemeral containers that are rebuilt from your source code on every deployment. Any files created at runtime (uploads, generated files) are not part of your source code and are deleted.
What is the cheapest way to persist files on Replit?
For small files, store them as base64 in your database. For larger files, Cloudinary offers a free tier with 25GB of storage. Supabase Storage also has a generous free tier.
Can I use Replit's database to store files?
Replit's key-value database can store small amounts of data. For actual file storage, use a cloud service like S3 or Cloudinary.
