Become a sponsor to Finbuckle

Support Finbuckle

We are Finbuckle, the creator and maintainer of MultiTenant, an open-source multi-tenancy library for .NET that helps developers build secure, flexible, and maintainable multi-tenant applications.

Effective November 10, 2026
For organizations that use Finbuckle commercially, we require an Open Source Maintenance Fee. This fee helps fund the ongoing maintenance, security, compatibility, and long-term sustainability of the project.

What started as a solution to a common architectural challenge has grown into a mature project used by developers and organizations around the world. Maintaining it means more than writing code—it includes reviewing contributions, answering questions, investigating issues, keeping pace with new .NET releases, improving documentation and samples, and making careful decisions that preserve compatibility for existing applications.

Our goal is to keep Finbuckle dependable, practical, and developer-friendly, while continuing to evolve it alongside the .NET ecosystem.

Sponsorship helps make that possible. Your support gives us more time to:

• Maintain compatibility with new .NET and ASP.NET Core releases
• Investigate bugs and respond to community issues
• Review and collaborate on pull requests
• Improve documentation, samples, and developer experience
• Design and implement new capabilities without sacrificing stability
• Keep the project healthy and sustainable for the long term

If Finbuckle saves your team time, simplifies your architecture, or has become an important part of your application, sponsoring the project is a meaningful way to support its continued development.

Whether you’re an individual developer or a company relying on Finbuckle in production, thank you for using the project, contributing to the community, and helping make open-source .NET better.
