Pourquoi c'est important

You have spent months building a game in a major proprietary engine, only to wake up to news that the company is changing its pricing model in a way that threatens your livelihood. You want to move to an open-source alternative, but the thought of manually rebuilding every scene, reassigning every material, and rewriting thousands of lines of code is paralyzing. You are trapped in an ecosystem you no longer trust because the technical barrier to leaving is simply too high.

  • · Conçu pour Indie game studios and solo developers with existing projects who want to switch engines but cannot afford to start from scratch..
  • · Monétisation la plus probable : One-time per-project license or usage-based pricing based on project size.

Mise sur le marché

Utilisateur cible exact

Indie game developers with half-finished projects in proprietary engines looking to migrate to open-source alternatives.

Nombre d'utilisateurs estimé

~20,000 active indie developers currently evaluating engine migrations.

Canal d'acquisition principal

Targeted outreach in specific game dev subreddits and Discord communities focused on open-source engines.

Ancre de prix

$99 one-time license per project migration.

Premier jalon

10 developers paying for early access to migrate a single scene or small project.

Périmètre MVP · 1–2 semaines

Semaine 1
  • Research and document the raw file structure of a basic scene in the source engine (e.g., YAML format).
  • Research and document the raw file structure of a basic scene in the target open-source engine.
  • Write a basic Python script to parse the source scene file and extract object coordinates and hierarchy.
  • Write a generator function to output those coordinates into the target engine's scene format.
  • Create a simple CLI tool that takes a source file and outputs a target file.
Semaine 2
  • Add support for extracting and translating basic material properties (colors, simple textures).
  • Integrate an LLM API to attempt basic translation of simple movement scripts.
  • Build a simple web interface where users can upload a source scene file.
  • Implement a processing queue to handle the file conversion on the backend.
  • Deploy the web app and create a landing page demonstrating a successful simple conversion.
Fonctions MVP: Automated scene hierarchy conversion · Material and texture mapping translation · AI-assisted script translation (e.g., C# to GDScript) · Migration readiness report highlighting incompatible features

Différenciation

Solutions existantes
UnityUnreal EngineGodot
Notre angle
There is a massive gap for middleware that abstracts engine lock-in, allowing developers to build logic and assets that can be easily ported between major platforms.

Pourquoi cela pourrait échouer

Auto-contre-argument — le signal de confiance le plus important

  1. 1The technical complexity of translating complex physics and custom shaders may prove impossible to automate reliably.
  2. 2Proprietary engine creators might encrypt or obfuscate their project files to intentionally prevent this kind of tool.
  3. 3Users might expect a flawless 1-to-1 conversion and churn when they realize manual cleanup is still required.

Résumé des preuves

Comment l'IA a synthétisé cet aperçu — pas de citations textuelles

Multiple developers expressed deep frustration with sudden corporate policy changes, describing them as betrayals of trust. Several commenters explicitly stated they migrated to open-source alternatives to protect their projects, indicating a strong market movement. The primary barrier mentioned is the loss of existing work and the time required to learn and rebuild in a new system.
