# macOS (Homebrew)

# Linux & macOS (install script)
curl -fsSL https://raw.githubusercontent.com/Resetnak/cooldeck/main/install.sh | sh && cooldeck --demo
Prefer Go? go install github.com/resetnak/cooldeck/cmd/cooldeck@latest. Prefer a binary? Every
release ships Linux, macOS and Windows
archives plus .deb/.rpm/.apk. --demo runs against deterministic sample data - the same data
the golden tests render - so you can judge the product before you hand it a token.
💡 Why CoolDeck?
Checking whether a deploy went through should not cost you a browser tab, a login, and three clicks through a dashboard. CoolDeck puts the same fleet - statuses, deployment history, runtime logs and the deploy button - into a terminal window you can leave open next to your editor, and drives all of it from the keyboard.
It talks to the Coolify REST API directly. No proxy, no agent, no daemon: one static binary that reads your config, pulls a token out of your OS keyring, and renders.

🚀 Quick Start
- Look before you connect:
cooldeck --demo- the full UI on deterministic fake data, offline. - Create a Coolify API token: in Coolify, profile → API tokens. Give it the least privilege you can live with (
readplus only the write scopes you actually want). - Connect:
cooldeck setupwalks you through URL, token and keyring storage. - Use it:
cooldeck. Press?for the key map,:for the command palette,/to filter.
One degraded app, start to finish: / to filter, enter for the detail, l for runtime logs, d to redeploy behind a confirmation, 2 a to watch it land in the active queue. Rendered from cassette.tape.
✨ Key Features
- 🖥️ The whole fleet on one screen: status, branch, last deploy and domain for every application, with filtering (
/) and sorting (S). - 🔎 Detail without a context switch: overview, deployment history, runtime logs and configuration as tabs on the same screen.
- 🛰️ Fleet tail: mark applications with
space, presst, and read their runtime logs interleaved in one buffer, each line named and coloured by the application it came from - the view Coolify's web UI cannot give you. - 📜 Real log ergonomics: follow, pause, wrap, in-buffer search with
n/N, copy the match, clear the buffer,+/-to widen or narrow the line window. - 🚀 Operations behind a confirmation: deploy, force deploy, restart, start/stop - every destructive action asks first, and only one mutation runs at a time.
- 🛟 Honest about failure: a refresh that fails keeps the last good data on screen behind a stale banner instead of blanking the list. See When Coolify blinks.
- 🔀 Several instances, one session: switch fleets with
3without restarting; add, edit and delete local instance entries from inside the TUI. - ⌨️ Keyboard-first, mouse-optional: vi-flavoured bindings borrowed from
lazygitandk9s, a command palette (:/Ctrl+K) for the day you forget one, and a?overlay that always shows the truth - every hint is generated from a singleKeyMap. - 🎨 Eight themes, responsive layout: auto, dark, light, Dracula, Catppuccin, Nord, Gruvbox, Tokyo Night; three-pane at 150+ columns, single column when the window is small.
- 🔐 Tokens you never see: OS keyring by default, and tokens are kept out of the UI, the logs, the toasts and the diagnostics export by construction.
- 🤖 An MCP server in the same binary:
cooldeck mcphands your fleet to an agent - read-only until you say otherwise. See Your fleet, in your agent. - 🧪 Offline demo mode:
--demois a full implementation of the same service interface, which is also what the golden snapshot tests render.
🛰️ Fleet Tail
The one view Coolify's web UI cannot give you. Mark the applications you care about with
space, press t, and their runtime logs arrive interleaved in a single buffer - every line named
and coloured by the application it came from. One incident, one screen, instead of a browser tab per
service.
f follows, space pauses, c copies the merged buffer, esc goes back. Coolify serves runtime
logs as whole snapshots rather than a stream, so CoolDeck polls one request per marked application
every 4 seconds, staggers them, and merges the replies by timestamp - up to five applications at a
time, and it says so when it drops the rest. The concurrency model is
ADR 0007.
🤖 Your Fleet, In Your Agent
cooldeck mcp speaks the Model Context Protocol over stdin/stdout,
so an agent can ask what is running, why a build failed, and what the logs say - through the same use
cases the TUI uses. No second HTTP client, no separate token, no daemon.
It cannot touch your production by default. The read-only surface is list_applications,
get_application, list_deployments, get_runtime_logs, get_deployment_logs and
get_instance_info. --allow-mutations adds deploy_application, restart_application,
start_application and stop_application - and nothing behind them asks for confirmation, because an
agent has no one to ask. Grant it deliberately, and prefer a token scoped to the instance you are
willing to let it operate.
// Point any MCP client at the binary you already have:
{ "mcpServers": { "cooldeck": { "command": "cooldeck", "args": ["mcp"] } } }
Try it before you wire it up: cooldeck mcp --demo serves the same tools against the offline demo
fleet, so you can watch an agent work without a Coolify instance in the loop.
📖 Full guide: docs/mcp.md - client setup, every tool and its arguments, what to decide before granting mutations, and troubleshooting.
🧭 How It Compares
CoolDeck is not a replacement for the Coolify web UI - it is the fast path for the handful of things you do twenty times a day.
Everything it does is an ordinary Coolify API call, so nothing here locks you in or out of the web UI.
🛟 When Coolify Blinks
Dashboards that clear the screen the moment a request fails are worse than useless during an incident. A failed refresh in CoolDeck keeps the last good snapshot, flags it as stale, and tells you how old it is. When the instance comes back, the next refresh heals it - no restart, and you keep your place in the list. Every API call is bounded by a 20-second timeout, every request kind is cancellable, and stale replies from a superseded request are dropped rather than rendered.

📦 Installation
No runtime dependencies. Every option below leaves you with a single static binary; only building from source needs a toolchain (Go 1.26.6+, no CGO).
Option 1: Homebrew (macOS)
brew install resetnak/tap/cooldeck
cooldeck --demo
Upgrades come with brew upgrade like anything else. The tap publishes a cask, which Homebrew on
Linux does not support - on Linux, use the install script below.
Option 2: Install script (macOS & Linux)
curl -fsSL https://raw.githubusercontent.com/Resetnak/cooldeck/main/install.sh | sh
Detects your platform, verifies the checksum, and drops the binary in ~/.local/bin. Override
with COOLDECK_INSTALL_DIR, or pin a version with COOLDECK_VERSION=v0.2.1. Read it first if you
would rather not pipe a script into a shell - it is short.
Option 3: Linux packages
# Resolve the newest tag once, then pick your package manager:
VER=$(curl -fsSLI -o /dev/null -w '%{url_effective}' \
https://github.com/Resetnak/cooldeck/releases/latest | sed 's|.*/v||')
BASE=https://github.com/Resetnak/cooldeck/releases/download/v$VER
# Debian / Ubuntu
curl -fsSLO "$BASE/cooldeck_${VER}_linux_amd64.deb"
sudo dpkg -i "cooldeck_${VER}_linux_amd64.deb"
# Fedora / RHEL
sudo rpm -i "$BASE/cooldeck_${VER}_linux_amd64.rpm"
# Alpine
curl -fsSLO "$BASE/cooldeck_${VER}_linux_amd64.apk"
sudo apk add --allow-untrusted "cooldeck_${VER}_linux_amd64.apk"
.deb, .rpm and .apk are built for amd64 and arm64 on every release - swap amd64 for
arm64 above if that is your machine.
Option 4: Release binaries
Download an archive for your platform from Releases,
unpack it, and put cooldeck on your PATH:
tar xzf cooldeck_*_Darwin_arm64.tar.gz # or Linux_x86_64, Linux_arm64, Darwin_x86_64
sudo mv cooldeck /usr/local/bin/
cooldeck version
Windows ships as a .zip. Every release carries a checksums.txt; verify before you trust it:
shasum -a 256 -c checksums.txt --ignore-missing
Archives for Linux and macOS (amd64 & arm64) and Windows (amd64) are built by
GoReleaser from v* tags.
Option 5: go install
go install github.com/resetnak/cooldeck/cmd/cooldeck@latest
Option 6: Build from source
git clone https://github.com/Resetnak/cooldeck.git
cd cooldeck
make build # -> bin/cooldeck, with version/commit/date baked in
./bin/cooldeck --demo
install -m 0755 bin/cooldeck ~/.local/bin/cooldeck
⚙️ Configuration
CoolDeck reads one TOML file. Find it - and check it - with:
cooldeck config path
cooldeck config validate
version = 1 # schema version; a newer one is rejected, never guessed at
default_instance = "production"
theme = "auto" # auto|dark|light|dracula|catppuccin|nord|gruvbox|tokyo-night
refresh_interval = "10s" # dashboard poll (minimum 3s)
log_refresh_interval = "2s"
log_lines = 300 # default log window (10–10000)
confirm_destructive_actions = true
confirm_deploy = false # set true to confirm ordinary deploys too
[ui]
nerd_font = "auto" # auto|on|off
compact_mode = "auto"
mouse = true
[instances.production]
name = "Production"
url = "https://coolify.example.com"
token_source = "keyring" # keyring|command|env|plaintext
token_key = "production"
COOLDECK_CONFIG_DIR moves the whole directory - handy for keeping experiments away from your real
setup. Full reference: docs/configuration.md.
🔑 Token sources
Resolved in this order: COOLDECK_TOKEN in the environment always wins, otherwise the instance's
token_source decides.
cooldeck auth add production # store a token in the keyring
cooldeck auth status production # is one there? (never prints it)
COOLDECK_TOKEN=… cooldeck # one-shot, nothing written anywhere
🖥️ CLI
cooldeck the TUI dashboard
cooldeck --demo offline demo data, no Coolify needed
cooldeck --instance production start on a specific instance
cooldeck --theme catppuccin theme override for this run
cooldeck --debug structured debug log (redacted)
cooldeck mcp serve the instance to an agent over MCP (read-only)
cooldeck mcp --allow-mutations ... and let it deploy, restart, start and stop
cooldeck setup first-run wizard: URL, token, keyring
cooldeck theme interactive theme picker with live preview
cooldeck auth add|status|delete <instance>
cooldeck config path|validate
cooldeck version version, commit, build date
🔒 Security
- Tokens stay out of sight: never rendered in the UI, never written to logs, toasts or the diagnostics export -
internal/logging/redact.goenforces the log side, and the diagnostics dump is secret-free by construction. - Anything that leaves the app is redacted: the fleet snapshot, the diagnostics export, every copy to the clipboard and every frame the MCP server sends pass through the same redactor, so a credential that slipped into a commit message or a runtime log does not travel with the paste. Logs on screen stay untouched.
- Log output is sanitised: raw ANSI control sequences from a remote log stream cannot repaint your terminal.
- Only
http/httpsURLs are ever handed to the browser. - Deleting an instance removes the local config entry and its keyring item. It never touches anything in Coolify.
- Permissions degrade gracefully: Coolify has no permission-introspection endpoint, so CoolDeck assumes full capabilities and switches individual features off on a
403- showing them disabled with a reason rather than hiding them. - What it does not protect you from: the config file is written
0600but aplaintexttoken source still puts the token on disk;insecure_skip_verify = truereally does disable TLS verification for that instance; and an MCP client started with--allow-mutationscan deploy, restart, start and stop without a confirmation, because an agent has nobody to ask. All three are opt-in, and all three are worth a second thought.

🏗️ Architecture
Layered so that the same use cases back the TUI, a CLI subcommand and the MCP server:
cmd/cooldeck → internal/cli cobra, flags, config, service construction
→ internal/tui Bubble Tea model + views (presentation only, no I/O)
→ internal/mcpserver MCP tools over stdio (no HTTP client, no TUI imports)
→ internal/app Service interface = the use cases
├── app/demo deterministic fake service (demo mode + golden tests)
└── coolify HTTP client + DTO → domain mapping
→ internal/domain, config, credentials, logging, platform, version
Built on Bubble Tea / Charm v2. Every TUI screen is covered by golden snapshots rendered from the demo service, so a layout regression fails CI instead of shipping.
Development
make check # fmt-check + vet + lint + test + build - run this before every PR
make run # go run ./cmd/cooldeck --demo
make test-race
make test-update-golden # refresh the TUI snapshots, then *read the diff*
make lint # staticcheck + golangci-lint (same versions as CI)
make bench # view rendering benchmarks
make vuln # govulncheck
The four GIFs in this README are generated, not hand-recorded: vhs cassette.tape, vhs tail.tape,
vhs mcp.tape and vhs outage.tape rebuild the binary and re-record against --demo, so they
cannot drift from the working tree. All of them run in a throwaway COOLDECK_CONFIG_DIR under
/tmp and touch nothing of yours.
🗺️ Roadmap
Shipped: applications dashboard, detail with logs, confirmed mutations, deployments queue,
deployment outcome notifications, multi-instance management, diagnostics, eight themes, demo mode,
an MCP server on the same app.Service, golden tests, multi-OS CI.
Next: richer in-TUI token sources beyond the keyring, optional read-only views for services, databases and servers, and a non-interactive CLI for scripts and CI.
