For developers

Ship features,
not infrastructure

Underneath the AI organization is an opinionated .NET 10 framework: domain-driven design, generated vertical slices, and every enterprise concern already wired in. Your team walks in and builds the part that makes your business different.

Code generation

Weeks of work,
generated in minutes

Describe an entity once. Source generators and the nessisone-codegen CLI produce the complete vertical slice: endpoints, commands, queries, validators, domain events, EF mappings, repositories, typed API clients, tests and UI.

  • Consistency guaranteed: every generated file follows the same patterns

  • Change once, regenerate: update a template and every slice follows

  • Juniors productive immediately: the generated code shows the right pattern

Unified commands

Write a command once,
reach it five ways

Every command you build is automatically available from the screen, the command palette, a shareable link, the REST API and plain-English AI, under one set of permissions.

ArchiveDocumentCommand
  • UI button
  • Command palette
  • Link
  • REST API
  • AI, in plain English

AI reaches all of them through two stable tools, search and run, instead of one tool per command. Prompts stay small no matter how big your app grows.

AI for your engineering team

AI that knows
your architecture

JuniorCoder

An AI coding team that understands NessisOne's conventions, domain model and patterns. It writes the change, runs it through a QA loop with an AI judge, and deploys it to a playground for review.

Add a command to archive a document and notify the owner
Creating ArchiveDocumentCommand with its handler, validator and domain event, following your CQRS pattern and notification preferences.

AI code review gate
Every commit can be reviewed by an AI gate that approves, rejects or flags it incomplete.
Systems Designer
Discovery agents study source, databases, APIs and interviews, then design, plan and generate a project.
Dev Workbench and Engineering Desk
A Windows coding workspace where an AI department pairs on your code, reviews branches and diagnoses builds.
Knowledge base over MCP
The framework documentation is served to your coding tools as an MCP server, with sources cited.
Documentation from source
Developer docs generated from the code, and end-user help written from screenshots of the running app.
MCP servers included
Expose your app's data and actions to outside AI tools, with authentication and audit.
Architecture

Built on the patterns
you already know

A principled, opinionated implementation of the industry's most trusted patterns, wired up and ready for production.

One-line startup
One call configures the app and discovers every installed package. A missing optional package never crashes startup.
Truth pattern
SQL is the source of truth; search, vector and graph stores are projections kept in sync for you.
Rules enforced at build
Analyzers flag code that bypasses tenant isolation, layering rules or repository conventions before it ships.
.NET 10 LTS
Built on the long-term support release of .NET, supported by Microsoft through 2028.

A working app in about five minutes

Start from the Kickstart template or the Visual Studio templates. With local sign-in and local file storage you need nothing but .NET and SQL Server to begin.

with the people who built it

Bring your domain and your constraints. We will walk through how NessisOne would structure it, what gets generated, and where your team writes the code that matters.
