Lumide is engineered with a strict performance mandate: one keystroke should touch O(log n) rope nodes, a handful of visible lines, and nothing else synchronously.
- Virtualized Rendering: Only what you see is what we draw.
- Asynchronous Pipeline: Syntax highlighting and diagnostics run off the main thread to keep the input loop lag-free.
- Rope Data Structure: High-performance text manipulation that handles large files with ease.
Lumide is designed to be a private and secure tool for developers.
- Local First: Your code stays on your machine.
- No Telemetry: We don't track your keystrokes or project data.
- Zero bloat: No background analytics processes.
