What it is

Kitty is a GPU-accelerated terminal emulator written primarily in Python and C, designed for high performance and rich feature support across Linux, macOS, and Windows. It uses hardware acceleration to render text and graphics, replacing traditional CPU-bound terminal rendering with modern GPU pipelines for speed and visual fidelity. Polyglot monorepo: 3rdparty/ contains vendored C libraries (base64 with architecture-specific codecs: AVX, AVX2, AVX512, NEON, SSE); Go modules handle orchestration and CLI (go.mod present); Python implements terminal logic and UI layer. Architecture separates low-level hardware codec acceleration from high-level terminal protocol handling.

Start here

Open these first:

• __main__.py — Entry point for the kitty terminal application; all contributors must understand the initialization flow.
• Makefile — Defines build targets and compilation process; essential for setting up development environment.
• go.mod — Go module manifest declaring all dependencies and Go version 1.26.0; critical for reproducible builds.
• embeds.go — Embeds resources and assets into the binary; core build artifact generation for cross-platform distribution.
• gen/__main__.py — Code generator for constants, parsers, and platform-specific glyphs; required pre-build step for consistent behavior.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/kovidgoyal/kitty.git && cd kitty. Build requires Go 1.26+ (evident from go.mod). For exact build steps, verify the repository's Makefile or setup documentation—no Python setup.py or…

Daily commands:

Not directly inferrable from provided data. Repository contains Makefile (1046 bytes) but contents not shown. Verify Makefile for build targets and check README for launch instructions. Likely: make or `go build ./...…

Key cautions & unknowns

• Concentrated ownership — top contributor handles 74% of recent commits
• GPL-3.0 is copyleft — check downstream compatibility
• SIMD codec selection (3rdparty/base64/lib/arch/*/codec.c files) is CPU-feature-gated: building on x86 generic may not enable AVX2 optimizations. Go 1.26.6 is pinned in go.mod; deviating versions may break builds. GPU…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
