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
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

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.
