Binary-to-Native Porting

We ingest binary-only input and reconstruct it into clean code. Port Windows-only legacy tools to Linux, Mac, or Web in hours, not months.

Legacy Porting

Binary Ingestion

Unlimited Feature Extensibility

Describe your intent and Nulla adds the feature. Complex systems remain maintainable because new features enter our rigorous 5-phase pipeline - never naively appended.

  • // Structural_Synthesis_v4.2
    // Phase 2: Atomic Binding

    export const BehavioralCore = {
    atomic_id: "PORT_LINUX_X64",
    constraints: "DETERMINISTIC_ONLY",
    binding_status: "SUCCESS",
    synthesize_runtime() {
    return this.map_to_ground_truth();
    }
    };
  • // Structural_Synthesis_v4.2
    // Phase 2: Atomic Binding

    export const BehavioralCore = {
    atomic_id: "PORT_LINUX_X64",
    constraints: "DETERMINISTIC_ONLY",
    binding_status: "SUCCESS",
    synthesize_runtime() {
    return this.map_to_ground_truth();
    }

Proof of Concept

Executing the Impossible

We port mission-critical legacy binaries to modern infrastructure in hours, not years - without ever seeing the source code.

DRAG TO EXPLORE

DRAG TO EXPLORE

Industry-First Deterministic Port: Notepad++ to Linux

We took the Notepad++ binary—without source code—and reconstructed it into a clean, portable implementation for Linux, Mac, and Web.

Impact :

5 Hours to initial transformation

Zero Source Code required for ingestion

100% Behavioral Parity with original binary

50+ Features synthesized post-deploy

Unlocking Mission-Critical Binaries: MobaXterm

Ported entirely from binary-only input, proving that complex, OS-specific enterprise software can be decoupled from legacy infrastructure in hours, not years.

Impact :

5 Hours to reconstruct from binary

Experimental Web + Python backend implementation

Decoupled from legacy OS dependencies

Eliminated Windows licensing overhead

Standardizing Software Portability: Linux Bash

Our first experiment in unoptimized behavioral reconstruction, setting the floor for our engine's capability to reimplement core OS utilities from description.

Impact :

15 Hours for initial transformation

10 Hours for full reimplementation from description

Scorecard Rank #2 bypasses GitHub Codespaces and Replit

Zero Technical Debt accumulation

Strategic Value

Core Benefits of Deterministic Reconstruction

Recover absolute control over your software ecosystem with a system designed for resilience, portability, and infinite extensibility.

Unmatched Portability

We transform legacy applications into clean, portable assets. Port Windows-only software to Linux, Mac, or Web without needing the original source code.

Deterministic Reliability

Eliminate the risk of AI hallucinations. Nulla uses a deterministic engine to ensure your rebuilt software behaves exactly as intended, every time.

Embedded Security

Security constraints are embedded at generation time, not patched on afterward. Deliver software hardened to a high level of demonstrable resilience.

Technical Debt Elimination

Stop maintaining expensive, insecure legacy environments just to keep mission-critical apps alive. Reduce operational overhead by moving to clean codebases.

Autonomous Self-Correction

Nulla finds and fixes issues autonomously by continuously refining output against the behavioral ground truth of the original system, regardless of complexity.

Infinite Extensibility

Add any feature you want, regardless of complexity. Simply describe your intent, and the system synthesizes new features without breaking the existing architecture.
