Configuration Reference
Complete reference for pitchfork.toml configuration files.
Configuration Hierarchy
Pitchfork loads configuration files in order, with later files overriding earlier ones:
- System-level:
/etc/pitchfork/config.toml(namespace:global) - User-level:
~/.config/pitchfork/config.toml(namespace:global) - Project-level:
.config/pitchfork.toml,.config/pitchfork.local.toml,pitchfork.toml,pitchfork.local.tomlfrom filesystem root to current directory
Within each directory, files are processed in this order:
.config/pitchfork.toml(lowest precedence in directory).config/pitchfork.local.toml(overrides.config/pitchfork.toml)pitchfork.toml(overrides everything in.config/)pitchfork.local.toml(highest precedence in directory, not committed to version control)
This mirrors mise behavior, allowing you to store project config in a centralized .config/ directory if preferred.
JSON Schema
A JSON Schema is available for editor autocompletion and validation:

File Format
All configuration uses TOML format:
namespace = "my-project" # optional, per-file namespace override
[daemons.<daemon-name>]
run = "command to execute"
# ... other optionsDaemon Naming Rules
Daemon names must follow these rules:
| Rule | Valid | Invalid |
|---|---|---|
| No double dashes | my-app | my--app |
| No slashes | api | api/v2 |
| No spaces | my_app | my app |
| No parent references | myapp | .. or foo..bar |
| No leading/trailing dashes | my-app | -app or app- |
ASCII alphanumeric, _, -, . only | myapp123 | myäpp or app@v1 |
The -- sequence is reserved for internal use (namespace encoding). See Namespaces for details.
Namespace Derivation Rules
- Global config files (
/etc/pitchfork/config.toml,~/.config/pitchfork/config.toml) use namespaceglobal - Project config files (
.config/pitchfork.toml,.config/pitchfork.local.toml,pitchfork.toml,pitchfork.local.toml) use:- Top-level
namespace = "..."if set in the config file - Otherwise, the parent directory name as namespace
- Top-level
- For
.config/pitchfork.tomland.config/pitchfork.local.toml, the namespace is derived from the project directory (the.configdirectory's parent), not from.configitself - If the derived directory name is invalid (
--, spaces, non-ASCII, etc.), parsing fails and you should set top-levelnamespace
Top-level namespace (optional)
Overrides the namespace used for all daemons in that specific config file.
namespace = "frontend"
[daemons.api]
run = "npm run dev"Notes:
pitchfork.local.tomlshares namespace with siblingpitchfork.toml- If both declare
namespace, the values must match - Global config files must use
global
Daemon Options
run (required)
The command to execute.
[daemons.api]
run = "npm run server"dir
Working directory for the daemon. Relative paths are resolved from the pitchfork.toml file location. If not set, defaults to the directory containing the pitchfork.toml file.
# Relative path (resolved from pitchfork.toml location)
[daemons.frontend]
run = "npm run dev"
dir = "frontend"
# Absolute path
[daemons.api]
run = "npm run server"
dir = "/opt/myapp/api"env
Environment variables to set for the daemon process. Variables are passed as key-value string pairs.
[daemons.api]
run = "npm run server"
env = { NODE_ENV = "development", PORT = "3000" }
# Multi-line format for many variables
[daemons.worker]
run = "python worker.py"
[daemons.worker.env]
DATABASE_URL = "postgres://localhost/mydb"
REDIS_URL = "redis://localhost:6379"
LOG_LEVEL = "debug"user
Unix user to run the daemon process as. This overrides [settings.supervisor] user for this daemon. Values may be usernames or numeric UIDs.
[settings.supervisor]
user = "app"
[daemons.api]
run = "npm run server"
[daemons.postgres]
run = "postgres -D /var/lib/postgres"
user = "postgres"
[daemons.low-port-web]
run = "python -m http.server 80"
user = "root"
[daemons.worker]
run = "./worker"
user = "501"Behavior:
- If
useris set, the daemon runs as that user. - Otherwise, if
[settings.supervisor] useris set, the daemon runs as that user. - When the supervisor is running as root and
[settings.supervisor] useris set, the default state directory, logs, and IPC sockets are stored under that user's state directory unlessPITCHFORK_STATE_DIRoverrides it. Pitchfork also chowns those state files to the configured user so non-root clients can read and write them. - Otherwise, if the supervisor was started as root via
sudo, daemons run as the sudo-calling user fromSUDO_UID/SUDO_GID. - If no run user can be derived, the daemon runs as the supervisor's current user.
- Switching to another user requires the supervisor to have root privileges; otherwise startup fails.
retry
Number of retry attempts on failure, or true for infinite retries. Default: 0
- A number (e.g.,
3) means retry that many times truemeans retry indefinitelyfalseor0means no retries
[daemons.api]
run = "npm run server"
retry = 3 # Retry up to 3 times
[daemons.critical]
run = "npm run worker"
retry = true # Retry foreverauto
Auto-start and auto-stop behavior with shell hook. Options: "start", "stop"
[daemons.api]
run = "npm run server"
auto = ["start", "stop"] # Both auto-start and auto-stopready_delay
Seconds to wait before considering the daemon ready. When started via pitchfork start or pitchfork run, defaults to 3 seconds if no other ready check is configured.
[daemons.api]
run = "npm run server"
ready_delay = 5ready_output
Regex pattern to match in output for readiness.
[daemons.postgres]
run = "postgres -D /var/lib/pgsql/data"
ready_output = "ready to accept connections"ready_http
HTTP endpoint URL to poll for readiness (2xx = ready).
[daemons.api]
run = "npm run server"
ready_http = "http://localhost:3000/health"ready_port
TCP port to check for readiness. Daemon is ready when port is listening.
[daemons.api]
run = "npm run server"
ready_port = 3000ready_cmd
Shell command to poll for readiness. Daemon is ready when command exits with code 0.
[daemons.postgres]
run = "postgres -D /var/lib/pgsql/data"
ready_cmd = "pg_isready -h localhost"
[daemons.redis]
run = "redis-server"
ready_cmd = "redis-cli ping"depends
List of daemon IDs that must be started before this daemon. Dependencies can be:
- short IDs in the same namespace (e.g.
postgres) - fully qualified cross-namespace IDs (e.g.
global/postgres)
When you start a daemon, its dependencies are automatically started first in the correct order.
[daemons.api]
run = "npm run server"
depends = ["postgres", "redis"]Behavior:
- Auto-start: Running
pitchfork start apiwill automatically startpostgresandredisfirst - Transitive dependencies: If
postgresdepends onstorage, that will be started too - Parallel starting: Dependencies at the same level start in parallel for faster startup
- Skip running: Already-running dependencies are skipped (not restarted)
- Circular detection: Circular dependencies are detected and reported as errors
- Strict validation: Invalid dependency IDs fail config parsing (they are not skipped)
- Force flag: Using
-fonly restarts the explicitly requested daemon, not its dependencies
Example with chained dependencies:
[daemons.database]
run = "postgres -D /var/lib/pgsql/data"
ready_port = 5432
[daemons.cache]
run = "redis-server"
ready_port = 6379
[daemons.api]
run = "npm run server"
depends = ["database", "cache"]
[daemons.worker]
run = "npm run worker"
depends = ["database"]Running pitchfork start api worker starts daemons in this order:
databaseandcache(in parallel, no dependencies)apiandworker(in parallel, after their dependencies are ready)
watch
Glob patterns for files to watch. When a matched file changes, the daemon is automatically restarted.
[daemons.api]
run = "npm run dev"
watch = ["src/**/*.ts", "package.json"]Pattern syntax:
*.js- All.jsfiles in the daemon's directorysrc/**/*.ts- All.tsfiles insrc/and subdirectoriespackage.json- Specific file
Behavior:
- Patterns are resolved relative to the
pitchfork.tomlfile - Only running daemons are restarted (stopped daemons ignore changes)
- Changes are debounced for 1 second to avoid rapid restarts
See File Watching guide for more details.
watch_mode
Select which file watcher backend to use for this daemon. Default: "native"
[daemons.api]
run = "npm run dev"
watch = ["src/**/*.ts", "package.json"]
watch_mode = "auto"Allowed values:
"native"- OS-native filesystem notifications (default)"poll"- Polling-based watcher (better compatibility on some NFS/remote mounts)"auto"- Prefer native, automatically fall back to polling if native watcher setup fails

expected_port
TCP ports the daemon is expected to bind to. Used for port conflict detection before starting a daemon.
[daemons.api]
run = "node server.js"
expected_port = [3000]
[daemons.multi]
run = "./start.sh"
expected_port = [8080, 8443]auto_bump_port
When true, pitchfork automatically finds an available port if the expected port is already in use. All ports in expected_port are bumped by the same offset to maintain relative spacing. Default: false
[daemons.api]
run = "node server.js"
expected_port = [3000]
auto_bump_port = trueBehavior:
- Tries incrementing all ports by the same offset (1, 2, 3, ...) up to
port_bump_attempts(default: 10) - Resolved ports are available via
pitchfork statusand in the start output - Useful for running multiple instances of the same service
port_bump_attempts
Maximum number of port increment attempts when auto_bump_port is enabled. Default: 10
[daemons.api]
run = "node server.js"
expected_port = [3000]
auto_bump_port = true
port_bump_attempts = 20boot_start
Start this daemon automatically on system boot. Default: false
[daemons.postgres]
run = "postgres -D /var/lib/pgsql/data"
boot_start = truehooks
Lifecycle hooks that run shell commands in response to daemon events. Hooks are fire-and-forget — they run in the background and never block the daemon.
[daemons.api]
run = "npm run server"
retry = 3
[daemons.api.hooks]
on_ready = "curl -X POST https://alerts.example.com/ready"
on_fail = "./scripts/cleanup.sh"
on_retry = "echo 'retrying...'"Fields:
on_ready- Runs when the daemon becomes ready (passes readiness check)on_fail- Runs when the daemon fails and all retries are exhaustedon_retry- Runs before each retry attempton_stop- Runs when the daemon is explicitly stopped by pitchforkon_exit- Runs on any daemon termination (stop, clean exit, or crash); also fires during supervisor shutdown
Hook commands receive environment variables: PITCHFORK_DAEMON_ID (fully-qualified namespace/name), PITCHFORK_DAEMON_NAMESPACE, PITCHFORK_RETRY_COUNT, PITCHFORK_EXIT_CODE, and (for on_stop/on_exit) PITCHFORK_EXIT_REASON ("stop", "exit", or "fail"). See Lifecycle Hooks guide for details.
cron
Cron scheduling configuration.
[daemons.backup]
run = "./backup.sh"
cron = { schedule = "0 0 2 * * *", retrigger = "finish" }Fields:
schedule- Cron expression (6 fields: second, minute, hour, day, month, weekday)retrigger- Behavior when schedule fires:"finish"(default),"always","success","fail"
mise
Enable mise integration for this daemon. When true, the daemon's command is wrapped with mise x -- to activate mise-managed tools and environment variables.
[daemons.api]
run = "node server.js"
mise = trueThis is especially useful for daemons running via pitchfork boot (login daemon mode) where interactive shell hooks haven't set up tool paths. When not set, falls back to the global general.mise setting. See mise Integration guide for details.
memory_limit
Maximum physical memory (RSS) for the daemon process. Accepts human-readable byte sizes. The supervisor periodically monitors the daemon's RSS and kills it if it exceeds the limit.
[daemons.worker]
run = "python worker.py"
memory_limit = "512MB"
[daemons.api]
run = "node server.js"
memory_limit = "2GiB"Supported formats: "50MB", "512MB", "1GiB", "256KiB", etc. Both SI (MB, GB) and binary (MiB, GiB) units are accepted.
Behavior:
- The supervisor checks RSS at each interval tick (configured by
general.interval, default10s) - When a daemon's RSS exceeds the limit, the process group is killed via
SIGTERM(thenSIGKILLif unresponsive) - The daemon is marked as
Errored, so ifretryis configured, it will be restarted (consuming a retry attempt) - Works reliably with all runtimes (JVM, Node.js, Go, Python, etc.) since it measures actual physical memory, not virtual address space
- For multi-process daemons (e.g. gunicorn workers, nginx workers), RSS is aggregated across the root process and all its descendants, consistent with the process-group kill used for enforcement
- Only affects the daemon's process group, not the pitchfork supervisor itself
- Default: no limit
cpu_limit
Maximum CPU usage as a percentage for the daemon process. The supervisor periodically monitors the daemon's CPU usage and kills it if it exceeds the limit.
[daemons.worker]
run = "python compute.py"
cpu_limit = 80 # 80% of one CPU core
[daemons.batch]
run = "./run-batch.sh"
cpu_limit = 200 # Up to 2 CPU coresSupported values: Any positive number. 100 = 100% of one CPU core. Values above 100 are valid on multi-core systems (e.g. 200 allows up to 2 full cores).
Behavior:
- The supervisor checks CPU usage at each interval tick (configured by
general.interval, default10s) - To avoid killing daemons during transient spikes (e.g. JIT warm-up, burst responses), the process is only killed after 3 consecutive samples exceed the limit. A single sample below the limit resets the counter. This threshold is configurable via
settings.supervisor.cpu_violation_threshold(default:3). - When the consecutive threshold is reached, the process group is killed via
SIGTERM(thenSIGKILLif unresponsive) - The daemon is marked as
Errored, so ifretryis configured, it will be restarted (consuming a retry attempt) - CPU usage is measured as a percentage of one core (not system-wide)
- For multi-process daemons (e.g. gunicorn workers, nginx workers), CPU usage is aggregated across the root process and all its descendants, consistent with the process-group kill used for enforcement
- Only affects the daemon's process group, not the pitchfork supervisor itself
- Default: no limit

Slugs for the reverse proxy are defined only in the global config (~/.config/pitchfork/config.toml), not in per-project pitchfork.toml files. The global config is the single source of truth for slug→project mappings.
# ~/.config/pitchfork/config.toml
[slugs]
api = { dir = "/home/user/my-api", daemon = "server" }
frontend = { dir = "/home/user/my-app", daemon = "dev" }
# If daemon name matches slug, it can be omitted:
docs = { dir = "/home/user/docs-site" } # defaults daemon = "docs"Each slug entry maps to:
dir— the project directory containing thepitchfork.tomldaemon(optional) — the daemon name within that project. Defaults to the slug name if omitted.
Use pitchfork proxy add to manage slugs:
pitchfork proxy add api # current dir, daemon = "api"
pitchfork proxy add api --daemon server # current dir, daemon = "server"
pitchfork proxy add api --dir /home/user/api --daemon srv # explicit dir and daemon
pitchfork proxy remove api # remove a slug
pitchfork proxy status # show all slugs and their state
