# 3. build the binary + symlink to ~/bin
bun build --compile src/cli.ts --outfile clarc
ln -sf $(pwd)/clarc ~/bin/clarc

# 4. set your secret
export CLAUDE_REMOTE_SECRET=dev  # add to .bashrc/.zshrc

# 5. use it like claude
clarc
clarc -r

# 6. open browser/phone
open http://localhost:7200

usage

server

just dev     # development with hot reload
just start   # production
just check   # lint + typecheck + test

Server runs on port 7200 (configure via PORT env var).

create device

just seed <secret> <name>

Creates a device with the given secret and name. The secret is used to authenticate the CLI wrapper.

Default if you just run just seed:

• secret: "dev"
• name: "dev device"

run claude

With the binary installed and CLAUDE_REMOTE_SECRET set, just use clarc like claude:

clarc                    # interactive
clarc -r                 # resume
clarc --help             # shows help
clarc -p "explain this"  # print mode

All arguments pass through to claude.

configuration

Environment variables (add to .bashrc/.zshrc):

export CLAUDE_REMOTE_SECRET=dev                    # required

Or use flags to override:
