Stop rebuilding the same
infrastructure every project

Think of NessisOne like a fully equipped commercial kitchen: the infrastructure is already there, your team walks in and cooks.

The Traditional Way

Every project starts from scratch

  • 6–12 months building auth, billing, and multi-tenancy before a single business feature ships

  • Senior engineers spend years on plumbing instead of product differentiation

  • Inconsistent patterns across projects: different auth strategies, data layers, UI conventions

  • Security debt accumulates as each team reinvents authentication and authorization independently

  • Junior developers are blocked waiting for architecture decisions and infrastructure to be ready

The NessisOne Way

Walk in and start building features

  • Day one productivity — register modules with one line, the framework handles the rest

  • Senior engineers focus on your competitive differentiators, not boilerplate infrastructure

  • Consistent architecture across every project, every team, every new hire — enforced by the framework

  • Security by default — hardened auth, fine-grained permissions, audit trails baked into every module

  • Juniors are productive immediately — source generators scaffold production-quality code automatically

Everything your enterprise
application needs

37+ production-ready packages covering every layer of a modern enterprise application. Plug in what you need. Skip what you don't.

Security & Access Control

Enterprise-grade authentication with Google, Microsoft, and Auth0 SSO. Fine-grained role and permission management with policy-driven access control. Encrypted secrets vault, comprehensive audit trails, and GDPR-compliant logging. Security defaults mean your app is hardened from commit one.

SSO / OAuth2 RBAC Audit Trails Secrets Vault GDPR Compliant SOC 2 Ready

Billing & Subscriptions

Stripe, PayPal, and Apple Pay integrated with full subscription lifecycle management. Usage-based billing, proration, trial periods, and churn analytics — without writing payment logic.

Stripe PayPal Apple Pay

Multi-Tenant Architecture

One deployment, thousands of customers — with complete data isolation at the repository layer. Tenant-scoped caching, routing, and storage. Scale from startup to enterprise without re-architecting.

Data Isolation Scoped Caching

Data & Storage

Full-text search, blob storage (Azure, local, OneDrive, FTP), performance caching with Redis, and comprehensive audit trail storage. EF Core with the Truth Pattern for reliable projections.

EF Core Redis Azure Blob

Notifications

Multi-channel delivery across email, SMS, in-app alerts, and database. Template management, delivery tracking, and retry logic built in. Never lose a notification.

Email SMS In-App

100+ UI Components

AI that ships with your app
— not bolted on later

NessisOne's AI capabilities are first-class citizens of the framework, not third-party add-ons wired together with hope and duct tape.

Conversational Assistant

Every NessisOne application gets a fully integrated AI chat assistant. Powered by Semantic Kernel with multi-provider support — OpenAI, Azure OpenAI, Anthropic, Google Gemini. Context-aware across your application's data, with conversation history and streaming responses.

Add a command to archive a document and notify the owner
Creating ArchiveDocumentCommand with handler, validator, and domain event. Following your project's CQRS pattern and notification preferences…

✓ ArchiveDocumentCommand.cs
✓ ArchiveDocumentHandler.cs
✓ DocumentArchivedEvent.cs
✓ ArchiveDocumentEndpoint.cs

Plain-English Commands

Users speak naturally; the AI routes to your application's command handlers. "Archive the Q4 report" becomes a typed command dispatched through your CQRS pipeline. No custom NLP training required — the framework handles intent-to-command mapping automatically.
