Tenantbox is a developer-focused platform designed to provide multi-tenant file storage for SaaS teams. It addresses the challenges of building per-tenant storage, enforcing quotas, and tracking usage without requiring custom logic or significant engineering time. By offering an API that enables per-tenant file storage, Tenantbox allows SaaS applications to avoid writing tenant isolation logic from scratch and simplifies the integration of file storage capabilities.
The platform operates by letting developers make two API calls: one to request a presigned upload URL and another to upload the file directly to storage. Files are stored on Cloudflare R2, an S3-compatible object storage service with global distribution and zero egress fees. Tenantbox ensures that files are uploaded directly from the client to Cloudflare R2, bypassing the application server entirely, which results in faster uploads and eliminates server-side bandwidth costs. Each tenant’s files are automatically namespaced, and tenants are created upon their first upload. The service enforces per-tenant storage quotas before uploads begin and updates usage totals automatically after every upload. Usage tracking, quota enforcement, and tenant isolation are managed in the background, removing the need for developers to maintain custom middleware, storage usage tables, or IAM policies.
Tenantbox is currently in early beta and is free to use during this phase. The free tier includes 1 GB of storage and unlimited tenants, with no credit card required. Pricing details will be made public before any limits are enforced. The platform is language-agnostic, requiring no SDK, and provides code snippets for various programming languages such as TypeScript, JavaScript, Python, PHP, Go, Java, Ruby, Swift, and C. Files remain accessible via standard presigned URLs, and file paths are stored in the user's own database, ensuring that users retain control over their data and are not subject to lock-in or export fees.
Tenantbox is positioned as an infrastructure tool for SaaS developers seeking to manage multi-tenant file storage, quota enforcement, and usage tracking in a streamlined and efficient manner.
In the Infrastructure & Backend space, Tenantbox takes a focused approach. It focuses on implementing secure, scalable multi-tenant file storage and quota management for SaaS applications without custom boilerplate. It is built as a B2B product for saaS developers and engineering teams. Tenantbox costs nothing to use. It runs on the web and API.
