# Measure AI Traffic on Vercel with no code changes

Every plan with AI Traffic can now connect Vercel as a crawler sensor. In **Settings › Integrations**, find **Vercel** under **Crawler sensors** and select **Set up**. Approve DevTune's Vercel integration, choose the Vercel projects to measure and select **Create drain**.

The drain filters on Vercel's side, so only requests from AI crawlers and answer fetchers reach DevTune. Like Cloudflare pull and edge middleware, it sees crawls, answer fetches and 404 demand. Each host is counted by one sensor: a host that Cloudflare or edge middleware already reports stays on that sensor.

The drain needs a Vercel Pro or Enterprise team with **IP Address Visibility › Show in Log Drains** turned on, so DevTune can check each crawler's address against its operator's networks. Your own agents can read the drain's state and each host's sensor from the traffic summary over API v2 and MCP.

Select **Disconnect Vercel** at any time and DevTune deletes the drain on Vercel. Read the [Vercel log drain docs](https://docs.devtune.ai/ai-traffic/setup#vercel-log-drain).
