Rendering

GPU-Accelerated Rendering

Blade uses wgpu to render across every GPU backend from a single codebase. The entire frame draws in just two instanced draw calls.

  • Vulkan, Metal, DX12, and WebGPU backends
  • Glyph atlas with row-based bin packing
  • Damage tracking - only re-render on changes
  • 60+ FPS under heavy output

> 3. Writes to database
 
Shift+Enter for new lines
Color

24-bit True Color

Full RGB color support with 256-color and true color escape sequences. Syntax highlighting, diffs, and status indicators render with pixel-perfect accuracy.

  • CSI 38;2;r;g;b m true color sequences
  • 256-color palette support
  • Bold, dim, underline, strikethrough, inverse

Built-in session multiplexer with WebSocket transport. Sessions persist across disconnects indefinitely - like tmux, but built into the terminal.

  • Persistent sessions that survive disconnects
  • WebSocket server with TLS and auth
  • QR code pairing for mobile devices
  • UDP auto-discovery on local network
