Configuration#

The keys in ~/.openprogram/config.json, what openprogram config can read and write, and the environment variable roundup. For the everyday entry point to changing settings, see Configuration and data directory.

What openprogram config can read and write#

openprogram config list              # every setting: value, group, apply mode
openprogram config get ui.web_port
openprogram config set ui.web_port 8101

The settings registry is defined in openprogram/config_schema.py (the single source of truth; the setup wizard, the TUI settings page, and the Web settings page all render from it). Every setting is labeled with an apply mode: live takes effect immediately, next_start takes effect the next time the worker starts.

key	Group	Meaning	Default	Applies
`ui.web_port`	Ports	legacy alias for the single port (kept for the deprecation window)	18100	next start
`ui.open_browser`	Ports	whether `openprogram web` opens the browser automatically	true	next start
`search.default_provider`	Search	default web search provider; `auto` picks the highest-priority configured one	auto	live
`memory.backend`	Memory	`local` (on-disk memory) or `none` (no prompt memory, recall, automatic writes, organizer, or memory threads)	local	next start
`memory.writer.model`	Memory	optional `provider/model` override for background writing; empty uses the default chat agent's provider, model, and credentials	empty	live
`proactive.heartbeat`	Memory	due-commitment reminder cadence: `daily` at 09:00 local, `hourly` at minute 00, or `off`; requires `cron-worker`	daily	live
`proactive.quiet_hours`	Memory	local-time interval in `HH:MM-HH:MM` form during which reminders are suppressed	23:00-08:00	live
`sandbox.mode`	Sandbox	`danger-full-access`, or `workspace-write` to apply the host-native sandbox to local model-driven commands: writes are limited to the working directory/configured roots, deny-read paths are blocked, and network is disabled	workspace-write	live
`sandbox.writable_roots`	Sandbox	extra directories a sandboxed command may write, as a JSON list	[]	live
`sandbox.deny_read`	Sandbox	globs a sandboxed command cannot read; defaults include credential paths. Linux cannot enforce middle-wildcard patterns such as `/.env`: use an exact path or a concrete directory deny such as `/absolute/path/to/secrets/` for sensitive content	see `openprogram config get sandbox.deny_read`	live
`sandbox.deny_write`	Sandbox	globs a sandboxed command cannot write, on top of the always-blocked function-watcher directory	[]	live
`sandbox.network`	Sandbox	whether a sandboxed command has network access	false	live
`sandbox.pass_env`	Sandbox	environment variable names to pass through besides the built-in allowlist	[]	live
`sandbox.unavailable_policy`	Sandbox	`refuse` fails the command when the platform backend is missing or cannot create its required isolation; `warn` runs it unsandboxed	refuse	live
`tools.disabled.<name>`	Tools	per-tool switch; written as members of the `tools.disabled` list	all enabled	live
`agent.output_style`	Agent	how replies are written; appends a block to the system prompt. See Output styles	default	live
`providers.<name>`	Providers	read-only status row (configured or not); configure with `openprogram providers login` or the Web UI	—	—

The local sandbox is host-native: Seatbelt on macOS and bubblewrap on Linux. Windows and unsupported platforms refuse commands while the sandbox is enabled unless the owner explicitly selects the unsafe sandbox.unavailable_policy=warn or sets sandbox.mode=danger-full-access. Docker is not an automatic fallback.

Top-level keys in config.json#

The top-level keys actually written to ~/.openprogram/config.json (do not edit by hand — go through openprogram config set, the setup wizard, or the Web UI):

Key	Meaning	Code
`ui`	`{port, web_port, open_browser}`, see the table above	`openprogram/config_schema.py`
`search`	`{default_provider}`	`openprogram/setup.py`
`memory`	`{backend, writer: {model}}`, see the table above	`openprogram/config_schema.py`, `openprogram/memory/`
`proactive`	`{heartbeat, quiet_hours}`, see the table above	`openprogram/config_schema.py`, `openprogram/proactive/heartbeat.py`
`tools`	`{disabled: [tool name, ...]}`	`openprogram/setup.py`, `openprogram/config_schema.py`
`sandbox`	`{mode, writable_roots, deny_read, deny_write, network, pass_env, unavailable_policy}`, see the table above	`openprogram/sandbox/__init__.py`, `openprogram/config_schema.py`
`default_provider`	Default LLM provider (written by the setup wizard)	`openprogram/setup.py`
`default_model`	Default model (written by the setup wizard)	`openprogram/setup.py`
`default_workdir`	Default working directory for agents	`openprogram/paths.py`
`providers`	Per-provider settings subtree (enabled models, custom models, etc.), managed by the Web UI model listing	`openprogram/providers/_config_read.py`, `openprogram/providers/storage.py`
`api_keys`	Environment variable name → API key mapping, written by the setup wizard and exported into the environment at worker startup. Used for web-search / TTS keys; LLM provider keys live in the credential store (`openprogram providers login`), not here	`openprogram/_setup_sections/sections.py`, `openprogram/webui/server.py`
`spec_migration_version`	One-time marker for the model-spec migration; see the code for its meaning	`openprogram/providers/storage.py`

Environment variables#

Set these in the shell that launches openprogram (or the worker). Every one has been verified against the code; each row names where it is defined.

Paths and instances#

Variable	Purpose	Code
`OPENPROGRAM_PROFILE`	State-directory profile, equivalent to `--profile`, reroutes to `~/.openprogram-<name>/`	`openprogram/paths.py`
`OPENPROGRAM_HOME`	Alternative base directory for auth accounts	`openprogram/auth/accounts.py`
`OPENPROGRAM_WORKDIR`	Default agent working directory (takes precedence over the config's `default_workdir`)	`openprogram/paths.py`

Ports and web#

Variable	Purpose	Code
`OPENPROGRAM_WEB_PORT`	the single worker port (default 18100); below explicit flags, above the persisted preference	`openprogram/worker/lifecycle.py`, `openprogram/_cli_cmds/web.py`
`OPENPROGRAM_NO_WEB`	`1` = the worker skips the frontend build gate and does not serve the web UI	`openprogram/worker/runner.py`
`OPENPROGRAM_WEB_NO_FRONTEND`	`1` = `openprogram web` skips the frontend and starts only the backend	`openprogram/_cli_cmds/web.py`
`OPENPROGRAM_DOCS_BASE`	Mount path of the docs site (default `/docs/`; must start and end with `/`)	`tools/docs_site/build.py`

Behavior switches#

Variable	Purpose	Code
`OPENPROGRAM_NO_AUTO_WORKER`	`1` = the TUI does not auto-launch a worker; connects only to an existing one	`openprogram/cli_ink.py`
`OPENPROGRAM_NO_AUTO_UPDATE`	`1` = disable auto-update	`openprogram/updater/runner.py`
`OPENPROGRAM_NO_SLEEP`	`1` = disable the memory sleep-consolidation scheduler	`openprogram/memory/scheduler.py`
`OPENPROGRAM_NO_PROGRAMS_WATCH`	`1` = disable the file watcher on the programs directory	`openprogram/functions/watcher.py`
`OPENPROGRAM_PROJECT_AUTOCOMMIT`	`0` = turn off project auto-commit	`openprogram/store/project/project_commit.py`
`OPENPROGRAM_WEBSEARCH_DISABLE`	Disable a web search provider by name (e.g. `ollama`)	`openprogram/functions/tools/web_search/providers/ollama.py`

LLM calls#

Variable	Purpose	Code
`AGENTIC_PROVIDER` / `AGENTIC_MODEL`	Provider / model that `detect_provider()` (and thus `create_runtime()`) picks first, before config-file and CLI detection	`openprogram/providers/registry.py`
`OPENPROGRAM_MAX_RETRIES`	Runtime retry count for transient API failures (default 6)	`openprogram/agentic_programming/runtime.py`
`OPENPROGRAM_RETRY_BACKOFF_BASE`	Base seconds for the exponential retry backoff (default 1.5)	`openprogram/agentic_programming/runtime.py`
`OPENPROGRAM_EXEC_TIMEOUT_S`	Default wall-clock budget in seconds for every `runtime.exec` when the caller passes no `timeout_s` (unset or `0` = unbounded)	`openprogram/agentic_programming/runtime.py`
`OPENPROGRAM_FALLBACK_MODELS`	Failover chain used when the main model fails before any output. Unset = the other enabled models of the same provider (max 2); a comma-separated `provider/model` list overrides it and may cross providers; `off` disables failover	`openprogram/providers/utils/failover.py`
`OPENPROGRAM_PROVIDER_STREAM_RETRIES`	Maximum retries for streaming requests	`openprogram/providers/utils/stream_retry.py`
`OPENPROGRAM_STRICT_TOOLS`	`0` = turn off strict tool schemas (on by default)	`openprogram/providers/_schema/__init__.py`
`OPENPROGRAM_FORCE_IPV4`	`1` = force an IPv4 source address (for broken IPv6 networks)	`openprogram/providers/utils/http_client.py`

Debugging#

Variable	Purpose	Code
`OPENPROGRAM_DEBUG_RUNTIME`	`1` = mirror runtime logs to stderr	`openprogram/webui/server.py`
`OPENPROGRAM_DEBUG_REGISTRY`	`1` = show function-registry import failures	`openprogram/functions/_registry.py`
`OPENPROGRAM_DEBUG_DISPATCHER`	`1` = dispatcher debug logs	`openprogram/agent/dispatcher/runtime_attach.py`
`OPENPROGRAM_DEBUG_PROVIDER`	`1` = provider-layer debug logs	`openprogram/providers/openai_codex/openai_codex.py`

Others#

The code holds a further batch of more internal variables (HTTP/SSE timeout tuning OPENPROGRAM_HTTPX_* / OPENPROGRAM_SSE_*, TCP keepalive OPENPROGRAM_TCP_*, per-provider retry counts OPENPROGRAM_<PROVIDER>_MAX_RETRIES, OPENPROGRAM_TASK_WORKERS, OPENPROGRAM_IMAGE_DIR, OPENPROGRAM_BROWSER_CDP_URL, etc.). grep -rn "OPENPROGRAM_" openprogram/ lists the full set; every variable is commented where it is defined.
