Build scalable software with Deterministic Accuracy.

Byggr isn’t an assistant. It’s an autonomous development engine.

While LLMs are great for summarization and conversation, they’re unreliable for real code. That’s why we use LLMs only to understand and structure requirements, not to generate software.

AI code is produced by our Deterministic Language Model, a rule-based, predictable system that outputs secure, repeatable, validated code at scale. It’s not a black box. It doesn’t guess. It builds.

This hybrid model, LLM + DLM + human collaboration, is what makes Byggr unique.
You don’t get generic code snippets. You get full, customized applications, including unit tests, documentation, and integrated stubs for your own custom code.

Byggr supports code generation across a growing set of programming languages and database technologies such as: C#, Python, Flutter, .NET, Java, SQL, MySQL, PostgreSQL, and many more are on the way.

Plus, our architecture is designed to be language-agnostic, so you can work across tech stacks or migrate projects without rewriting from scratch.

Soon, you’ll be able to add your own custom language patterns, part of our open, developer-first philosophy.

We’re also building toward full cross-language reconstitution: generate an app in one language, regenerate it in another. Total flexibility. Maximum leverage.

Byggr-generated code adheres to proven software design principles and patterns, including:

Separation of Concerns
Programming to the Interface
Lazy Initialization
Singleton, Composite, Facade, Flyweight Patterns
Front Controller, Proxy, Strategy, Command Patterns
Chain of Responsibility, Servant, Active Object, Lock, Messaging Patterns

You don’t just get code, you get maintainable, scalable architecture from day one.

Yes. Every line of code generated by Byggr is yours to extend.
You can inject custom logic, modify files, or evolve the system model.

Our Smart Re-Authoring ensures your changes persist across future generations; no overwrites, no regressions, no friction. You stay in control. Always.

Your data stays yours.

Byggr isolates all project inputs during ingestion and lets you run private enterprise-grade LLMs if desired. During generation, the DLM will operate locally, no cloud dependency required.

All data is encrypted with industry-standard SSL protocols, and generated code enforces safe defaults with zero use of unauthorized APIs or insecure data flows.

Security isn’t a layer, it’s a core feature.

Yes, and we’re making it even easier.

Byggr accepts requirements in nearly any format, and outputs clean, documented source code ready for handoff or extension. Future versions will support GitHub and repo integrations, along with your own design and architectural patterns.

You can plug Byggr directly into your current stack, or use it to define a better one.

Every project is different,  but the gains are real.

Byggr accelerates requirements processing, automates infrastructure, generates full-stack code, and creates tests; all in minutes.
That means fewer sprints, faster delivery, and drastically lower maintenance costs long-term.

We’ve seen teams save hundreds of hours and tens of thousands of dollars on a single build.
Less grunt work. More progress.
