Why CastCodes

Built for your workflow,
not a subscription model.

Everything you loved about a modern terminal — without hosted services, telemetry, or platform lock-in.

🔒

Local First

No cloud accounts, no upstream auth. Everything runs on your machine. Your data never leaves your terminal.

Blazing Fast

GPU-accelerated rendering on a battle-tested terminal core. Startup is instant; response is immediate.

🌿

Open Source

Every line is auditable. Fork it, extend it, contribute back. No black-box telemetry, no hidden analytics.

🎨

Modern UI

Blocks-based command history, inline completions, and a clean interface that gets out of your way.

🔗

Deep Integration

Registers castcodes:// URL scheme and cast-codes CLI for seamless workspace opens.

🛡️

Zero Telemetry

Upstream crash reporting, billing hooks, and hosted services are fully disabled — not just opt-out.

Comparison

Same great terminal foundation. Very different relationship with your data.
