Integrations
An integration is a curated third-party tool you can attach to an app from a small catalog. Attaching one stores the field values it needs (an API key, a DSN) through the same envelope encryption every app secret uses, and injects the tool's env vars into the app's container at its next build or deploy.
This is env-var injection only: there is no deep webhook or API wiring, and no auto-detection-gated suggestions. If a tool needs more than an env var to work, it isn't in this catalog.
Attaching an integration
From the dashboard: open an app, go to its Integrations tab, and use Attach integration under Third-party tools. Search the catalog, pick a tool, fill in its required field(s), and save. The values you type are never shown again after saving.
From the CLI:
levelrail apps integrations catalog
levelrail apps integrations add my-app sentry --field SENTRY_DSN=https://key@o0.ingest.sentry.io/0
levelrail apps integrations list my-app
levelrail apps integrations remove my-app <attachment-id>Precedence
Integration env vars are injected as a default, the same tier as a project/organization/environment shared env var: if the app's own app.yaml or dashboard env already declares the same variable name, the app's own value always wins. Detaching an integration removes its env vars cleanly at the app's next deploy.
Catalog
| Tool | What it does | Env var(s) | Setup |
|---|---|---|---|
| Sentry | Error tracking and performance monitoring. | SENTRY_DSN | Paste the DSN from your Sentry project's client keys settings. |
| PostHog | Product analytics, feature flags, and session replay. | NEXT_PUBLIC_POSTHOG_KEY, NEXT_PUBLIC_POSTHOG_HOST (optional, defaults to PostHog Cloud US) | Paste your project API key from PostHog's project settings. |
| Datadog | APM tracing, infrastructure, and log monitoring. | DD_API_KEY, DD_SITE (optional, defaults to datadoghq.com) | Paste an API key from Datadog's organization settings. |
| Axiom | Log and event data platform. | AXIOM_TOKEN, AXIOM_DATASET | Create an API token and dataset in Axiom, then paste both. |
| Better Stack | Log management and uptime monitoring. | LOGTAIL_SOURCE_TOKEN | Paste the source token from your Better Stack log source. |
| LogSnag | Real-time event notifications and analytics. | LOGSNAG_TOKEN, LOGSNAG_PROJECT | Paste an API token and your project name from LogSnag's settings. |
| BugSnag | Error monitoring and stability management. | BUGSNAG_API_KEY | Paste the API key from your BugSnag project's settings. |
| New Relic | Full-stack observability and APM. | NEW_RELIC_LICENSE_KEY | Paste your account's license key from New Relic's API keys page. |
Every entry links to that vendor's own current setup docs; the env var names above are read directly from those docs, not guessed.
How this compares
Vercel and Netlify both ship an integrations marketplace of their own; this one is simpler and self-hosted, limited to env-var injection rather than a full OAuth/webhook connection to each vendor's platform.
