Head-to-Head Competitor Analysis

Why SpriteCraft 2D is cheaper, faster, and more secure than TexturePacker ($49.99/yr subscription).

Comparison Metric	SpriteCraft 2D	TexturePacker ($49.99/yr subscription)
License Model & Price	$24.99 (One-Time Perpetual)	$49.99 per year recurring
Annual Financial Savings	Save $50/yr every single year
Competitor Drawbacks	Recurring annual subscription fee, online license validation nagware, missing integrated normal map generation
Why Vivian Is Better	One-time $24.99 perpetual license, built-in dynamic normal map generator and collision hull tracer, zero subscription
Execution Environment	100% Offline Air-Gapped	Mandatory cloud check-in
Runtime Telemetry	Zero Telemetry (0.00KB sent)	Cloud telemetry & user tracking

Headless CLI Reference & Execution

SpriteCraft 2D includes a headless command-line binary ready for automation pipelines, cron daemons, and CI/CD runners:

# Headless command execution:
spritecraft --pack ./sprites/ --out atlas.png --format godot --generate-normals --trim-whitespace
# Cryptographic node-lock activation:
spritecraft --activate YOUR-CROCKFORD-KEY

Core Architecture & Asymmetric Security
