For .NET teams building AI products
500+ hours of senior .NET work.
$1,499.
Multi-tenant AI infrastructure that would take your team 2-3 months to build. Production-ready, tested, documented. Skip the plumbing and ship your product.
Solo license: $399 for single-project use.
The math
What it costs to build this infrastructure from scratch vs. buying it ready.
Build it yourself
Buy Nexus.NET
Even if your team is faster, $1,499 is less than one day of a senior engineer's time.
What goes wrong when you build it yourself
The demo works. Then you hit production.
Data leaks between customers
One missed .Where() clause and Customer A sees Customer B's data. Your multi-tenant app isn't really multi-tenant.
→ Nexus.NET: PostgreSQL RLS enforces isolation at the database. The query physically can't return wrong-tenant rows.
RAG that vanishes on restart
In-memory vector stores are fine for demos. Your embeddings disappear when the container restarts.
→ Nexus.NET: pgvector stores embeddings in Postgres. Survives restarts, backs up with your database.
Security as a last-minute scramble
Two weeks before launch: "We need vulnerability scanning." Your team scrambles to add security gates.
→ Nexus.NET: Gitleaks, Trivy, smoke tests already in CI. Security scanning runs on every commit.
Months of plumbing, no product
Your team spends Q1 on infrastructure. Competitors ship features. Your roadmap slips.
→ Nexus.NET: Start with the plumbing done. Ship features in week one.
What's already built
Not a starter template. A running application with the hard parts done.
True multi-tenancy
PostgreSQL Row-Level Security policies on every tenant table. Tenant context propagation through EF Core interceptors. Integration tests verify every table has RLS enabled.
Your team doesn't write isolation logic. The database handles it.
Durable RAG
pgvector stores embeddings in Postgres. Document processing pipelines with Hangfire. Hybrid search with vector + keyword matching. Retrieval survives restarts.
Not in-memory demo code. Real persistence that scales.
AI orchestration
Semantic Kernel with config-driven personas. Board Mode routes queries to relevant experts, builds context from RAG, synthesizes responses. Not just one chat endpoint.
Add personas in config. No code changes required.
Auth & security
JWT with refresh tokens. BCrypt password hashing. Account lockout after failed attempts. Per-endpoint rate limiting. Redis-backed distributed counters.
Background jobs
Hangfire with Postgres storage. Tenant-aware job execution. Document processing, embedding generation, stuck job recovery. Dashboard included.
DevOps ready
Terraform configs for Azure. Docker Compose for local dev. GitHub Actions CI/CD. Health endpoints. k6 load tests. Staging smoke scripts.
Verified, not just claimed
Concrete numbers. Run the verification yourself after purchase.
What the audit report covers
Full audit report with exact commands and outputs included with purchase.
One price. Full source. No recurring fees.
You're buying production infrastructure, not a SaaS subscription. Deploy it, modify it, own it.
Solo
For individual developers shipping one product.
- Full source code (backend + frontend + infra)
- Single-project commercial license
- All documentation and runbooks
- 12 months of updates
Team
For teams and agencies shipping multiple products.
- Everything in Solo
- Multi-project commercial license
- Deploy for multiple clients
- Priority support via email
That's less than one day of senior engineer time.
Questions
What exactly am I buying?
Full source code for a production .NET application: API, Angular frontend, database schemas, background jobs, and deployment configs. Plus 20+ documentation files covering architecture, deployment, and operations. You own it—no subscription, no vendor lock-in.
Why not just build it ourselves?
You can. The question is whether spending 500+ engineering hours on infrastructure is the best use of your team's time. Most teams would rather buy the baseline for $1,499 and invest in product differentiation instead of rebuilding multi-tenant isolation and security scanning.
Is this production-ready or just a demo?
Production-ready. 96 test classes, zero high/critical vulnerabilities in security scans, full CI/CD pipeline, and deployment documentation. The audit report shows exact commands and pass/fail results you can verify yourself.
What about ongoing maintenance?
Your license includes 12 months of updates. After that, you own the code—keep using it forever. The codebase follows .NET LTS releases. Team license includes priority email support.
Can multiple projects use this?
Solo ($399): One project, one developer.
Team ($1,499): Multiple projects, entire team. Use it as the foundation for all your AI products.
What's NOT included?
Hosting: You deploy to your own infrastructure (Azure, AWS, etc.).
UI polish: The Angular frontend is functional, not designer-polished.
Compliance certification: Security gates are included, not SOC2/HIPAA audits.
Skip the plumbing. Ship your product.
Your team's time is worth more than rebuilding infrastructure that already exists.
