cysh $ voice "deploy the staging branch"
Deploying branch staging to cytherra-staging.fly.dev... done in 14sEvery layer designed for developers who live in the terminal.
The terminal is the primary interface, not an afterthought. Every system action is a command away.
Claude Code, OpenClaw, and NemoClaw run directly from the shell. AI is woven into the OS, not bolted on.
Stripe, Supabase, Slack, and Notion ship as pre-connected MCP servers. Your tools are always ready.
A Rust-based shell with object pipelines and structured output. Pipe JSON, not strings.
Text, voice, camera, and files all flow through one unified input bar. Talk to your OS.
Designed for 9-10" ARM64 tablets with gesture navigation, split views, and swipe commands.
IDE, browser, file manager, and Kanban board included. Everything a developer needs, nothing extra.
Linux 6.x kernel, open OS, community device trees. Inspect, modify, and contribute to every layer.
From bare tablet to full dev environment in minutes.
Any ARM64 tablet with 2 GB+ RAM. We maintain device trees for popular models, or wait for the Cytherra Arc.
Download the image, flash to an SD card or internal storage. Boot into CytherraShell in under 60 seconds.
Claude Code is ready. MCP servers are connected. Open a terminal and ship your next project.
