StepMetrics vs Vercel Web Analytics
Vercel Web Analytics is built into Vercel hosting. StepMetrics works wherever your site runs, includes custom events and revenue on the free plan, and gives your coding agent a key that can read analytics and nothing else.
Where they differ
| StepMetrics | Vercel Web Analytics | |
|---|---|---|
| Where it runs | Any site that can load a script, and any app or server that can send JSON. | Projects deployed to Vercel. |
| Free plan | 200,000 events a month, custom events included, 400 days of data. | Hobby: 50,000 events a month, no custom events, a one-month reporting window. Collection pauses at the limit. |
| Paid plans | Pro is $19 a month for 1,000,000 events. Scale is $99 for 10,000,000. | On a Vercel Pro team, $0.03 per 1,000 events with a 12-month window. Web Analytics Plus adds a 24-month window for $10 a month. |
| Custom event properties | Any properties, plus exact revenue. | 2 per event on Pro, 8 with Web Analytics Plus. |
| Ask questions from your editor | A read-only key: twenty-eight analytics tools, and nothing that can change your account. | Vercel's official MCP server can query visitors, page views and custom events. Connecting gives the AI tool the same access as your Vercel account, including deployments. |
| Your own AI agents | Runs, model calls, tokens and cost, on the same event meter. | Not part of Web Analytics. |
Trying it alongside Vercel
You can keep Vercel's analytics and add StepMetrics to the same project in one line, then compare what each can answer. If you ever move a site off Vercel, or run one elsewhere already, StepMetrics keeps every site in one account regardless of where it is hosted.
