Multi-tenant file storage for developers. Built for SaaS teams.
Stop writing tenant isolation logic from scratch. Tenantbox gives your SaaS per-tenant file storage, quota enforcement, and usage tracking in two API calls. Files go directly to Cloudflare R2, your server is never in the way.
We boast faster uploads!
Files go straight to storage - your server is never in the way.

Multi-tenant storage is harder than it looks.
Every SaaS team eventually hits the same six problems. Most discover them in production.
Building it yourself
- —Write custom S3 path logic for every upload endpoint
- —Build quota-check middleware and keep it consistent
- —Maintain a storage_usage table that never drifts
- —Debug upload timeouts caused by server proxying
- —Manage IAM policies as tenants are created and deleted
- —Pay egress fees every time a user downloads a file
Typical time to ship: 2–4 weeks of engineering time
With Tenantbox
- ✓Two HTTP calls: get presigned URL, PUT file, done
- ✓Quotas checked before the upload even begins
- ✓Usage totals updated automatically on every upload
- ✓Files go directly to Cloudflare R2 your server stays free
- ✓Tenants created on first upload, deleted on request
- ✓Zero egress fees globally, always
Typical time to ship: under an afternoon

Your files' actual home
Files are stored on Cloudflare R2, S3-compatible object storage with global distribution and zero egress fees. Your data isn't on some mystery server. It's on infrastructure trusted by millions of developers worldwide.
Files stored in isolated per-tenant namespaces on R2
Your data, always
No lock-in by design
Every file you upload is accessible via a standard presigned URL. You store the file_path in your own database. If you ever leave Tenantbox, your data is yours, no export process, no hostage fees.
File paths stored in your DB, always accessible
Early access, honest terms
Beta, not vaporware
Tenantbox is in active beta. The API is live, uploads work, and early users shape the roadmap. Free tier includes 1 GB storage and unlimited tenants. Pricing will be public before any limits are enforced.
No credit card required ever, for the free tier
Two calls. Any stack.
No SDK required. Copy the snippet for your language and you're done.
import axios from 'axios'
import fs from 'fs'
// Step 1 — Get presigned upload URL
const { data } = await axios.post(
'https://api.tenantbox.dev/api/storage/upload/',
{
tenant_id: 'user_123',
filename: 'contract.pdf',
content_type: 'application/pdf',
},
{
headers: {
'Authorization': 'Bearer sk_live_xxx',
'Content-Type': 'application/json',
},
}
)
console.log('File path:', data.file_path)
console.log('New tenant:', data.is_new_tenant)
// Step 2 — Upload directly to Tenantbox storage. Your server never sees the file.
const fileBuffer = fs.readFileSync('contract.pdf')
await axios.put(data.presigned_url, fileBuffer, {
headers: { 'Content-Type': 'application/pdf' },
})
console.log('Upload complete!')All the features you need to ship faster.
Manage uploads, enforce quotas, and isolate tenants without writing the boilerplate yourself.

Tenants per project
From API call to stored file in two steps.
No complex SDK. No server-side file handling. Just two HTTP calls and your file is safely stored, isolated, and tracked.
Request a presigned URL
Your server makes one authenticated POST to Tenantbox with the tenant ID, filename, and content type. You get back a presigned upload URL and the file path.
Upload directly to storage
Your client PUTs the file directly to the presigned URL. The file never touches your server which means faster uploads and no bandwidth cost on your end.
Done - tenant & file tracked
Tenantbox automatically creates the tenant on first upload, namespaces the file, enforces storage quotas, and starts tracking usage. Zero boilerplate on your side.
Your server is never the bottleneck
Because uploads go client → storage directly, large files don't block your API, consume memory, or rack up egress charges. Tenantbox handles isolation, quotas, and tracking in the background.
