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

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

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.
