FucuFlow Studio
Cinematic Screen Recording & Auto-Zoom Workspace
Empowering developers to tell clearer stories.
FucuFlow was founded on a simple belief: high-impact video creation should be fast, private, and free of subscription paywalls.
Traditional video editing software was built decades ago for Hollywood filmmakers, making it hopelessly complex for modern software engineers, product designers, and creators who just want to showcase their work.
Core Engineering Principles
Why we built FucuFlow differently than commercial cloud screen recorders.
100% Local & Private
Your screen captures never touch a cloud server. Video processing, zooming, and rendering happen entirely on your machine via IndexedDB and GPU shaders.
Hardware-Accelerated WebCodecs
Built on modern W3C WebCodecs and WebGL 2.0 to deliver real-time 4K rendering with silky-smooth frame rates and negligible battery consumption.
Intelligent Focal Camera Easing
Catmull-Rom spline curves with critically damped spring physics glide the virtual camera effortlessly into user interactions, banishing abrupt cuts.
Permissive MIT Open Source
Every single line of code is open on GitHub. No subscription gates, no feature paywalls, and no hidden telemetry. Built by developers, for creators.
Standard screen captures vs. FucuFlow Presentation
Standard recordings force viewers to squint at high-resolution monitors to find which tiny button was clicked. FucuFlow creates automatic focal journeys.
- ✕Flat 2D canvas with unreadable tiny interface fonts
- ✕Requires manual keyframing of every camera pan
- ✕Uploads private work recordings to third-party clouds
- ✕Monthly recurring subscription costs & watermarks
- Cinematic auto-zooming targeting mouse clicks
- Spline spring easing with realistic 3D perspective
- 100% offline device storage via IndexedDB & Tauri
- 100% Free & Open Source under permissive MIT License
Rapid evolution in the open.
Built with transparency and shaped directly by community feedback.
v0.1.4 Cross-Platform
Universal macOS DMG, Windows installer, and Linux AppImage packages powered by Tauri Rust.
WebGL GPU Pipeline
Hardware-accelerated real-time 3D canvas tilts, isometric angle presets, and cursor ripple effects.
Focal Spline Engine
Autonomous mouse tracking with cluster-based zoom anchors and sub-second timeline keyframe snapping.
Open Source Genesis
Founded by Eric Va to provide an open-source, local-first alternative to closed screen recording tools.
Created by Eric Va.
FucuFlow is designed and maintained by Eric Va. It combines screen capture technology, dynamic spline camera choreography, and offline privacy into a clean, focused editing environment.
