Ditching Electron for Rust: Building Cross-Platform Apps with Multiple AI Models

The author shares their journey of transitioning a video editing app to a cross-platform architecture. Due to performance bottlenecks with Electron when handling long videos and multiple subtitles, they switched to writing the core CLI logic in Rust and building the UI with various frameworks on top.
To validate the technical feasibility, the author used AI coding tools to create multiple PoCs:
- GPT-5.6 Sol delivered a decent initial version.
- Cursor + Grok 4.6 generated code extremely fast, but the overall quality was slightly worse.
- Claude produced the best version so far, though it still needs refinement.
The author notes that while AI significantly reduces the cost of writing code, testing and QA costs remain. Unifying core logic in Rust minimizes cross-platform testing overhead.
