Product areas

One portal, one Coding Suite.

The public website focuses on the release Coding Suite: installer, documentation, sandbox testing, metrics, account access, and support.

/coding

Coding Studio

Install the release compiler studio, activate `closedbit-coding`, and learn `.cbp` syntax with copy-ready examples.

/metrics

Measured Performance

See the current ClosedBit versus C++ snapshot, system specs, and why the measured rows are faster.

Sandbox and docs

Try shape, then compile locally.

The browser sandbox checks common `.cbp` mistakes and previews simple 256-bit results. The docs page is built for copy-and-paste learning.

Browser sandbox

Practice `.cbp`, load examples, check structure, and copy the result into Studio.

Open Sandbox

Copy-ready docs

Compiler commands, app templates, game templates, storage, UI, and license notes in copyable blocks.

Open Docs

License account

Login at the start, activate the product license, and keep entitlement visible.

Copy examples

Paste these into Studio.

Short, honest examples that match the current `.cbp` direction and avoid Python/C++ filler.

Storage value
library CB-Storage

fn main() {
    u256 coins = 1_000_000 + 250_000
    CB-Storage.write_text("save.cb", to_string(coins))
    println("saved coins")
    save coins
}
Render window
library CB-Render
library CB-Input

fn main() {
    init_window(960, 540, "ClosedBit Window")
    while (!should_close()) {
        handle_events()
        clear(0x071018)
        draw_text(24, 24, "ClosedBit", 0x64F1AC, 24)
