2020–2025

Vercel Drains (formerly Log Drains) now support exporting OpenTelemetry traces, Web Analytics events, and Speed Insights metrics in addition to logs. This provides a unified pipeline for streaming complete observability data to external systems like Datadog, Honeycomb, Grafana, and Elastic. Drains can be configured as custom HTTP endpoints or through turnkey integrations. Data is correlated across logs, traces, analytics, and performance metrics, enabling end-to-end observability. Available on Pro and Enterprise plans.

Introducing Vercel Drains: Complete observability data, anywhere

9/15/2025

Renamed 'Log Drains' to 'Vercel Drains' to reflect expanded capabilities beyond logs. Added support for exporting OpenTelemetry traces, Web Analytics events, and Speed Insights metrics. Enhanced data correlation by enriching logs with trace and span IDs. Introduced two drain types: Custom drains (HTTP endpoints with configurable data types, sampling rates, formats like JSON, NDJSON, Protobuf, and security options) and Integration drains (turnkey integrations with partners like Dash0, Statsig, Datadog, and Logflare).

Expanding observability on Vercel

4/8/2025

This post announces the expansion of observability integrations on the Vercel Marketplace with new native integrations from Sentry, Checkly, and Dash0. It highlights that these tools connect directly through the Vercel Marketplace with integrated billing, single sign-on, and access to provider dashboards. A key technical contribution is the introduction of Log Drains for native integrations, allowing users to send logs from Vercel projects to third-party providers like Dash0 for deeper insights and centralized monitoring. This capability was previously only available to connectable accounts.
