A native macOS GUI shell for Claude CLI — multi-session, multi-pane, built on top of the full Claude Code harness.
Jetstream is a Tauri desktop app that wraps the claude CLI in a modern three-pane interface. It gives you the power of Claude Code's agentic engine — tools, subagents, permission modes, session history, slash commands, the whole thing — inside a purpose-built GUI designed for running multiple sessions simultaneously.
It doesn't replace Claude Code. It augments it. Under the hood, Jetstream spawns real claude processes in stream-json mode, wires their output into a reactive UI, and lets you manage many concurrent agentic sessions across different working directories without touching a terminal.
Those tools bundle their own model access — you pay their subscription, get their context window, their tool set, their rate limits. When Claude releases a new model or a new agentic capability, you wait for them to ship it.
Jetstream is different:
- Your subscription, your limits. It runs against your own
claudeCLI, which uses your Anthropic or Claude.ai subscription. Every capability Claude Code ships — new models, extended thinking, MCP servers, agents, hooks — is available the day it lands, with no middleman. - The full harness, not a stripped-down API. Cursor and friends call the Claude API directly with a limited tool set. Jetstream runs the actual
claudebinary, which means you get every feature the CLI exposes:/compact,/memory, session resumption,--dangerously-skip-permissions, the whole plugin ecosystem, hooks you've configured globally. - Multi-session from the ground up. Run an agent fixing a bug in one pane, another writing tests in a second session, a third doing research — all from different working directories, all simultaneously.
- Transparent cost tracking. Every session shows live token usage and USD cost from the real Claude API response, not an estimate.
- Three-pane layout — workspace switcher (left), active chat with live todo panel (center), subagents + token/cost view (right)
- Multi-session — unlimited concurrent sessions per working directory; sessions persist and are resumable across restarts
- Full permission mode control — cycle through
bypassPermissions,plan, andacceptEditswith Shift+Tab; color-coded badge shows current mode at a glance - Live subagent tracking — see active subagents in real time as Claude spawns them; last 5 completed stay visible
- Slash command palette — type
/to autocomplete any Claude Code slash command;/modelswaps models mid-session while preserving history - Input history ring — navigate your last 5 sent messages with arrow keys
- Message queue — send messages while Claude is thinking; they're held and drained automatically
- Per-directory project commands — configure
run,test, andbuildcommands per repo; run them with one click and see the last 15 lines of output in a toast - Caffeinate integration — prevents macOS sleep while a session is active
- Context bar — visual 1M token window usage indicator; turns red above 80%
A prebuilt .dmg will be available for purchase on the website — coming soon.
Jetstream is open source. If you have the Rust and Node toolchain, you can compile and run it yourself at no cost.
Prerequisites:
- Rust (stable)
- Node.js + pnpm
- Tauri CLI v2 (
cargo install tauri-cli) - The
claudeCLI installed and authenticated
git clone https://github.com/r0k3tkutt3r/jetstream
cd jetstream
cargo tauri buildThe compiled .app will be in src-tauri/target/release/bundle/macos/.
# Install frontend dependencies
cd ui && pnpm install && cd ..
# Start the hot-reload dev build (backend + frontend)
cargo tauri devSet CCSHELL_CLAUDE_BIN=/path/to/claude to override the auto-detected claude binary.
Set RUST_LOG=debug to see stderr from spawned claude processes.
