Configuration reference

Every configuration key of BrowserHive (50 keys), generated from the zod schema in @browserhive/contracts/config. For a guided introduction see the configuration guide.

Precedence

Four sources, lowest to highest precedence. Rightmost wins.

defaults  <  environment (BROWSERHIVE_*)  <  browserhive.config.json  <  CLI flags

Standard OTEL_* variables are read as a sub-source just below BROWSERHIVE_* (provenance env(otel)). When a key is supplied by more than one source, startup logs one line per key naming the winner and what it shadowed; secret values render as <redacted>:

config: maxSessions=8 (cli) shadows config-file=4, env=2
config: logLevel=debug (config-file) shadows env=info
config: authTokens=<redacted> (cli) shadows env=<redacted>

The same provenance is shown by browserhive config show, the System page of the dashboard and GET /api/v1/system/config. An empty value in the environment or the config file is a usage error, not “unset”.

Naming

Every key has one camelCase name. The other spellings are mechanical: --maxSessions, BROWSERHIVE_MAX_SESSIONS, "maxSessions". CLI flags are case-sensitive; kebab-case flags are unknown and fail with a “did you mean” hint. Unknown flags, environment variables and file keys stop startup with exit code 64.

Canonical key	CLI flag	Environment variable	Config file key
maxSessions	--maxSessions	BROWSERHIVE_MAX_SESSIONS	"maxSessions"
otelEndpoint	--otelEndpoint	BROWSERHIVE_OTEL_ENDPOINT	"otelEndpoint"
allowInsecureBind	--allowInsecureBind	BROWSERHIVE_ALLOW_INSECURE_BIND	"allowInsecureBind"

Config file discovery

First hit wins: --config <path> (or BROWSERHIVE_CONFIG), then ./browserhive.config.json, then <dataDir>/browserhive.config.json. The file is plain JSON; "$schema" is the only extra key tolerated. A config file found inside the data directory may not set dataDir. The JSON Schema is config.schema.json (also printed by browserhive config schema).

Value grammars

Grammar	Accepted forms
boolean	true, false, 1, 0, yes, no (case-insensitive). CLI: --admin means true, --admin=false or --noAdmin sets false; --admin false is not accepted.
duration	integer plus ms, s, m, h or d; a bare integer is milliseconds.
bytes	integer plus B, KiB, MiB, GiB, KB, MB or GB; a bare integer is bytes.
integer / port	decimal integer, range-checked per key; ports are 1–65535.
host	IPv4 literal, IPv6 literal (with or without brackets) or an RFC 1123 hostname.
enum	exact member, case-sensitive.
path	relative paths resolve against the working directory (CLI, env) or the config file directory (file).
list	CLI/env: comma-separated, trimmed, no empty items. File: JSON array of strings.
map	CLI/env: k=v,k2=v2 (first = splits). File: JSON object of strings.
url	absolute http: or https: URL.

OpenTelemetry environment variables

Variable	Key
OTEL_EXPORTER_OTLP_ENDPOINT	otelEndpoint
OTEL_EXPORTER_OTLP_HEADERS	otelHeaders
OTEL_EXPORTER_OTLP_PROTOCOL	otelProtocol
OTEL_SERVICE_NAME	otelServiceName
OTEL_TRACES_SAMPLER_ARG	otelSampleRatio

Cross-field rules

Checked after all sources are merged. Violations exit with code 64 unless noted.

1. minAttentionWait must be less than attentionTimeout when it is greater than 0.
2. humanize=true requires stealth to be standard or max.
3. fingerprint=true (set explicitly) requires stealth to be standard or max.
4. captcha=attention (set explicitly) requires admin=true and transport=http.
5. admin=true requires transport=http (ADMIN_REQUIRES_HTTP, exit 3).
6. auth=token requires transport=http.
7. otelEndpoint, otelProtocol, otelHeaders, otelServiceName and otelSampleRatio require otel=true.
8. trustedProxies requires a non-loopback host.
9. screenshotTrace=true requires trace=true.
10. blocklistWatch=true requires blocklist to be set.
11. A non-loopback host without auth=token and without allowInsecureBind=true is refused (INSECURE_BIND_REFUSED, exit 3).

Reserved keys

These names are reserved for future releases. Setting any of them fails fast with a “reserved” message: proxy, proxies, proxyRotation, notifications, notificationChannels, otelMetricsInterval, captchaSolver, extensions, profiles, resourceBudget, tenant.
