SigNoz for Vercel (Marketplace Integration)

The SigNoz integration on the Vercel Marketplace lets you forward logs and distributed traces from your Vercel projects to SigNoz with a one-click install — no manual drain configuration or custom headers required.

See Stream Telemetry from Vercel to SigNoz for step-by-step drain setup, including self-hosted SigNoz.

Overview

The SigNoz + Vercel integration enables:

Automatic log collection via log drains, scoped to the sources and environments you configure
Distributed tracing via Vercel's native trace drain with per-environment sampling rules and optional request path filtering
A single pane of glass for all your observability needs — no more jumping between tools

Under the hood the integration creates two Vercel drains (one for Logs, one for Traces) that push data directly to your SigNoz ingestion endpoint.

Prerequisites

A Vercel Pro or Enterprise account
An instance of SigNoz Cloud

Step 1: Open the SigNoz Marketplace Listing

Go to vercel.com/marketplace/signoz and click Connect Account.

Step 2: Authorise the Integration

A Connect SigNoz Account dialog appears. Fill in the following:

Select a Vercel team to install the integration to.
Select which projects the integration will have access to — choose All Projects or pick specific projects.
Review the required permissions (Read for Team/Projects; Read and Write for Drains, Installation, and Integration Resources).
Click Connect Account.

Step 3: Configure SigNoz Credentials and Signals

After authorising, Vercel connects to the SigNoz integration configuration page. Enter your SigNoz details and choose which signals to forward:

Ingestion credentials

Field	Value
SigNoz Ingestion URL	The ingestion endpoint for your SigNoz Cloud region
Set Ingestion Key	Your ingestion key from SigNoz Settings > Ingestion Settings

Logs

Toggle Logs on to enable log forwarding. Then configure:

Set Log Sources — select one or more sources to forward: Static, External, Build, Edge, Lambda, Firewall, Redirect.
Log Sampling Rules — define sampling rates per environment (production, preview, development). See Drop Logs for advanced filtering strategies.

Traces

Toggle Traces on to enable trace forwarding. Then configure:

Trace Sampling Rules — set a sampling rate per environment. See Drop Spans for advanced filtering strategies.
Request Path Filter (optional) — restrict tracing to requests matching a specific path prefix.

Save

Click Add Integration. Vercel creates the log drain and/or trace drain automatically and redirects you to the integration settings page.

Step 4: Verify the Installation

After saving, Vercel redirects you to the integration settings page where you can confirm:

The Permissions granted to SigNoz.
Which projects SigNoz has access to.

To confirm the drains were created, go to Team Settings > Drains. You should see two new drains: one for Logs and one for Traces, both connected to your selected projects.

Step 5: Validate Data in SigNoz

Give it a minute for data to flow, then:

Logs — open Logs Explorer in SigNoz and look for entries with Vercel-specific attributes such as source, projectName, and deploymentId.
Traces — open Traces in SigNoz and look for spans originating from your Vercel projects.

Troubleshooting

No data appearing in SigNoz

Incorrect Ingestion URL — confirm the URL matches your SigNoz Cloud region exactly.
Invalid Ingestion Key — re-check the key in Settings > Ingestion Settings in SigNoz. Ensure there is no leading/trailing whitespace.
Drain not active — in Vercel go to Team Settings > Drains and check the drain status. Click a drain to see error details if it shows a warning.
Pro/Enterprise plan required — Vercel drains are only available on paid plans. Verify your plan at Team Settings > Billing.

Integration shows an error after "Add Integration"

Retry by removing and re-adding the integration from the Vercel Marketplace.
Double-check that the Ingestion URL does not have a trailing slash or extra path segment.

Next Steps

Set up alerts to get notified when your Vercel applications contain errors.
