About Kantiro
Kantiro is the core backend for organizations that need serious authentication, authorization, and subscription management without rebuilding those foundations for every product.
What we built
Kantiro provides multi-tenant organizations, role-based and object-level access control, subscription plans with permission gates, and REST APIs that frontends and mobile apps can integrate with. It handles identity, authorization, and org structure so your team can focus on customer-facing features.
Who it is for
Agencies, consultancies, and SaaS teams that work with multiple clients or business units and need per-organization isolation, audit-friendly access rules, and a single place to manage users, clients, projects, and files.
How it works
Applications authenticate users via JWT tokens against Kantiro's API. Permissions are enforced server-side through ACL and subscription checks. File uploads use presigned URLs so content goes directly to object storage (S3-compatible or Azure Blob) while metadata stays in Kantiro.
