Build scalable software with deterministic accuracy.
The first development platform delivering hallucination-free, production-grade software for professional engineers.
The future is hybrid.
Byggr pairs LLM agents for understanding specs with our proprietary Deterministic Language Model (DLM). This hybrid combination produces scalable code with zero hallucinations and full predictability.

Our multi-layered Hybrid AI approach
Start your project by uploading your documentation. Byggr understands natural language and written/visual documents.
Byggr converts your requirements into models and deterministically creates secure, structured, and production-ready applications.
Refine, iterate, and customize the initial output, tailoring your product for specific needs and use cases.
"LLM-only coding tools are incomplete, leaving engineers with bloated, confusing, and fragile prototypes instead of trusted software."

THE DIFFERENCE IS CLEAR
Today's AI code generation tools are built on probabilistic models, which are hallucination-prone, unpredictable, and unfit for serious software development. Enterprises, services firms, and startups alike are frustrated: they need real production code, not risky experiments.

THE ADVANTAGE IS POWERFUL
Byggr does not simply accelerate starting projects—it accelerates delivering them at scale, with trust and control. Our hybrid approach solves what pure LLM solutions cannot: consistency, security, compliance, and maintainability at enterprise standards.
HOW IT WORKS
Byggr combines natural language understanding with deterministic software generation, so you can go from messy input to bulletproof output, fast.
PRDs. Data models. Natural language prompts. AI Agents ingests natural, unstructured inputs and proposes a system model, architecture, components, and data flows, purpose-built for your use case.
No black box. No surprises. Developers review, edit, and approve the system model; the source of truth that governs everything downstream. You stay in control.
Byggr’s Deterministic Language Model (DLM) takes over. It produces production-grade code, complete with unit tests, infrastructure, and documentation, with zero hallucination, guaranteed.
Need to evolve the system? Add a new feature? Smart [Re]Authoring ensures your improvements are preserved, and every regeneration respects what you’ve already built.
Export the code. Push to your repo. Plug into CI/CD. Byggr outputs clean, modular code you can drop into your workflow without a rewrite. It’s your software; deploy it whenever and however you want.
Software doesn’t stop at launch, and neither does Byggr. Easily add new features, expand functionality, and adapt your system as your business grows, with full traceability, smart [re]authoring, and system-level control.
Proven in the most complex development environments
Broken CDRL database, flawed and incomplete, unfit for production.
Byggr repaired the database and generated 961,000+ lines of clean .NET Core code in under 45 minutes, fully aligned with Navy standards.
Reduced development time from a year to 45 minutes—no manual cleanup, no delays, no compromises.
15-person team, 10 months building a government accounting system—couldn’t meet requirements.
Two developers rebuilt it in 8 weeks using Byggr, generating 1.3 million lines of code.
Cut down effort from 150 months of work to just 16 weeks; enterprise-grade quality.
Internal team spent two weeks building an API but failed code quality and security tests.
New developers rebuilt it (API + admin UI) in under 5 minutes with Byggr—code scored 96 on VeraCode.
Turned weeks into minutes, saving 240+ hours and $20,000 in costs.
