Bangsai is a professional-grade drag-and-drop builder for people who are tired of platform walls. Pixel-perfect control. No lock-in. No ceiling.
Move, resize, and align anything with pixel precision. No broken layouts. No guessing where things will land.
Interactions at sixty frames per second. Instant feedback. Rendering engineered to feel like a real design tool — not a webpage.
Export your code. Extend the engine. Move hosts. Bangsai is yours the moment you build it.
Smart alignment, responsive inheritance, multi-select precision, and a professional command system — engineered as one coherent tool, not a pile of plugins.
Snap to edges, centers, baselines, and equal spacing automatically. The guides fade in exactly when you need them — and never when you don't.
Absolute, Flex, and Grid — switch between them anytime without breaking your structure.
Design for desktop, tablet, and mobile with a proper inheritance model. Override only what needs overriding.
Build once, reuse everywhere. Structured sections, nested containers, and a registry you can extend.
Select many. Align, distribute, and resize as one. Works across containers — with proper bounds math, not approximations.
Every action tracked, every change reversible. Transactions group what belongs together — undo a drag, not a thousand micro-moves.
Ship landing pages at the speed your ideas move. No design debt from day one.
Build, test, and iterate layouts without a developer in the loop. Own your conversion.
Extend the engine. Register components. Plug in your stack. No abstraction tax.
Ship faster for every client. Reusable systems, consistent output, zero platform lock-in.
No credit card. No onboarding call. Open the editor and ship something in the next ten minutes.
