enabled-features

Static feature-flag source used across Studio, docs, and www. The source of truth is enabled-features.json; every flag listed there is enabled (true) or disabled (false) at build time.

Using a flag

import { isFeatureEnabled } from 'common/enabled-features'

if (isFeatureEnabled('logs:templates')) {
  // ...
}

const { logsTemplates, logsMetadata } = isFeatureEnabled(['logs:templates', 'logs:metadata'])

Passing an array returns a camelCased object so consumers can destructure.

isFeatureEnabled(feature, runtimeDisabledFeatures?) accepts an optional list of features disabled at runtime (e.g. from the authenticated profile) that compose on top of the static defaults.

In Studio, prefer useIsFeatureEnabled from @/hooks/misc/useIsFeatureEnabled — it layers the authenticated profile's disabled_features and the self-hosted runtime override (below) on top of the static JSON.

Runtime override (Studio self-hosted)

Self-hosted Studio deployments can disable flags at container start time without rebuilding the image. Set one env var per flag under the ENABLED_FEATURES_ prefix:

ENABLED_FEATURES_LOGS_ALL=false
ENABLED_FEATURES_LOGS_TEMPLATES=false
ENABLED_FEATURES_BRANDING_LARGE_LOGO=true

Env var values are true / false (case-insensitive). Any other value is logged and ignored.

Key → env name mapping

Uppercase the feature key and replace every non-alphanumeric character (:, _, -) with _:

Feature key	Env var name
logs:all	ENABLED_FEATURES_LOGS_ALL
branding:large_logo	ENABLED_FEATURES_BRANDING_LARGE_LOGO
docs:self-hosting	ENABLED_FEATURES_DOCS_SELF_HOSTING
logs:show_metadata_ip_template	ENABLED_FEATURES_LOGS_SHOW_METADATA_IP_TEMPLATE

Mapping is forward-only (known key → expected env name), so snake_case vs colon collisions like branding:large_logo / branding_large:logo never come up.

Env vars prefixed with ENABLED_FEATURES_ that don't match a known feature are logged and ignored — a catch for typos.

Resolution order (Studio runtime)

1. ENABLED_FEATURES_* env vars (self-hosted only — route is a no-op when IS_PLATFORM === true)
2. profile.disabled_features from /platform/profile
3. enabled-features.json static value
4. Default (enabled)

Scope & limitations

• Studio only. The runtime override is surfaced through a Next.js API route and React Query, which docs and www don't use — their flag resolution stays build-time from enabled-features.json.
• Hosted is unaffected. The API route returns an empty list when IS_PLATFORM === true; hosted Studio continues to derive disabled features exclusively from the authenticated profile.
• Brief flash of unstyled flags. Before the override fetch resolves, flags default to their JSON value. For features gated as "enabled in JSON, disabled by runtime override", there's a brief window where the UI shows the feature before it's hidden.
• Support.constants.ts call site is build-time only. apps/studio/components/interfaces/Support/Support.constants.ts calls isFeatureEnabled('billing:all') at module load to build CATEGORY_OPTIONS, which is then spread into Zod form schemas. That one call site resolves from the static JSON and cannot be runtime-overridden without a larger refactor.

Disable everything (for tooling)

ENABLED_FEATURES_OVERRIDE_DISABLE_ALL=true forces every flag to false. Used by the docs embeddings pipeline to produce a filtered index. This is a server-only env (no NEXT_PUBLIC_ prefix) and short-circuits over everything else.

Adding a new flag

1. Add the key to enabled-features.json with the desired default.
2. Add the key and a description to enabled-features.schema.json, including it in the required array.
