Seer is Sentry's AI Debugging agent that has access to all the context that Sentry pulls together from your applications. Sometimes it shows up predicting bugs before they ship to prod. Sometimes it's catching issues in prod and bringing you the fix. Seer pulls from distributed traces, logs, profiles, stack traces, errors, and your codebase, and helps you find the broken parts of your application and fix them faster.

Configuring source maps for your Next.js application with a Sentry project gives you detailed information about where performance issues and errors are triggered in your code, making it faster to debug and resolve issues.

Setting up Sentry is literally one CLI command. This video walks you through how to create a new Next.js project on Sentry, how to install Sentry into that project, and how to trigger and monitor your first error.

Set up a Log Drain from Vercel and monitor all of your application data in Sentry. We'll take a quick look at how to set up a Log Drain, and show you two quick examples of how they can be used.

Stack traces tell you what broke. They rarely tell you why. In this video, Serge walks through a real Next.js production bug that only affected Firefox and Safari. The error showed up clearly in Sentry, but the stack trace alone wasn’t enough to explain what was going wrong. The missing piece turned out to be logs. You’ll see how adding logs to a Next.js API route exposed unexpected request data, how those logs connected back to traces, and how that context made the root cause obvious and easy to fix.

Aggregate and query logs on Sentry. Add logs to your errors, errors to not only make debugging easier, but also give valuable context to Seer AI. Logs help you and Seer better understand issues.

You can use the Sentry MCP server to debug issues in applications that are built in v0. You can also use it to create projects, pull down configurations, or dig into performance issues in applications. Check it out.

We're looking at what building a standard set of tools to use in Claude Code looks like for Sentry - and Claude's plugin marketplace is a great way to distribute them. Take it for a spin - the plugin distributes the MCP server, a few skills for setting up core parts of Sentry, and a few commands to use.
