We can't believe it's already been one week since Nothing But [Inter]net!

Thank you to our guest speakers for making this such a fun and interactive experience 🤓 and thank you to all of you who came out to fill the room!

HumanX Cabana · Luma In town for HumanX? Come to our happy hour and relax with engineers and founders building with AI. PlanetScale, Sentry, and Inference are taking over Natoma…

In town for HumanX next week? 👀

Join us for an evening at the HumanX Cabana — a laid-back happy hour with great people, strong drinks, and even better music.

Space is limited — request your spot here! luma.com/620oj82n

Join us live next Thursday to learn about dashboards in an agentic era 🤓

See you there! luma.com/885s4jmc

Send your existing OpenTelemetry traces to Sentry You don't need to rip out your OpenTelemetry instrumentation to use Sentry. Two env vars point your existing traces to Sentry's trace explorer.

If you're already using OpenTelemetry, you don't need to change a thing to have your existing traces show up in Sentry's trace explorer.

Sentry's OTLP support is currently in open beta 🎉

Seer Agent: Debug Anything Use Sentry's Seer Agent anywhere in the Sentry UI, CLI, MCP server, and more, to debug your applications and resolve…

Seer, our AI debugger, will soon be available in agent/chatbot form! And you'll be able to ask anything you want about your Sentry account in natural language.

Here's a demo with Paul to show you exactly what you can do with Seer Agent: youtu.be/AUjXZvFWAi8

Your AI agent is running, then all of a sudden goes completely off the rails. Why?

Stop by our booth at HumanX next week April 6-9 to learn how Sentry's Agent Monitoring is keeping the bots in check 🤖

We'll be at booth #1212!

New live (free) workshop just dropped!

Join us on April 14 at 10am PT for a session on observability consolidation with Sentry & Recurly 🤝

RSVP here: sentry.io/resources/wo...

Cookbook: Debugging & Monitoring Recipes Step-by-step recipes for debugging, monitoring, and fixing issues with Sentry.

Got a clever workflow that uses Sentry in your dev setup? A prompt chain, an automation, a sneaky integration that saves you hours? Let us know and we'll turn the best ones into official recipes

Check it out! 👇
sentry.io/cookbook/

A few favorites live in the Cookbook already:
- Monitor your Claude Code, OpenCode, and pi sessions with full AI observability
- Fix production issues in Cursor using Sentry MCP + Seer
- Monitor your MCP server with a single function call

We're launching a cookbook!

But not for food...for cooking with Sentry 😏

We've built a library of step-by-step workflows that show you how to use Sentry (and the Sentry MCP) to automate debugging, monitoring, and everything in between

Next.js Observability Gaps & How to Close Them Next.js hides errors across three runtimes. Here's how to close the gaps in hydration errors, server actions, ORM queries, and AI monitoring.

Our latest blog post covers the specific observability gaps and how to close them with Sentry 🤗

Next.js Observability Gaps & How to Close Them Next.js hides errors across three runtimes. Here's how to close the gaps in hydration errors, server actions, ORM queries, and AI monitoring.

Next.js gives you SSR, routing, and edge runtimes for free. But its three-runtime architecture means errors hide, DB queries disappear behind ORMs, and server actions swallow useful messages before they hit the browser.

Here's an example where a .meta file was missing. AssetImporter would've returned null. Switch builds would've been broken without any indicators.

But Seer caught it first in code review and saved this dev from a world of pain.

Matter of fact, we even added ourselves to the website homepage. Any other questions?

Seer fixes Seer: How our debugging agent helped fix itself How a latency optimization in Seer's region fallback logic turned a minor GCP outage into a full EU service disruption, and how Seer helped diagnose it.

We've been asked before: "if you don't use your products, why should I?"

And to that, I say,
1. We DO use our own products (a lot)

2. I raise you our latest blog post, where we talk about how Seer not only fixes Sentry, but Seer fixes itself 👇

Here's one instance where the validation logic was right, but the placement was wrong 😔

Seer caught a bug that would've prevented Ryan's users from editing any upcoming race event — before the app ever shipped.

Have you heard of Seer Code Review?

Everyone meet Ryan, a Sentry employee who's using Sentry and Seer to build his side-project, a training app to help runners plan workouts for upcoming races.

Here's how Seer Code Review has been helping him:

Sentry Metrics is in Open Beta 📊

Track key signals in your application with counters, gauges, and distributions, using the SDK you already have installed.

We allow high-cardinality. “Is a certain user triggering a queue backlog?”

Free during beta → docs.sentry.io/product/metrics/

You're probably overdue for a Sentry SDK upgrade Half of all Sentry JS SDK installs are on v8 or older. If you're one of them, here's what you're missing, and how to close the gap without the pain.

Check out our latest blog post to upgrade to v10 and get the most out of all Sentry has to offer: blog.sentry.io/overdue-for-...

You're probably overdue for a Sentry SDK upgrade Half of all Sentry JS SDK installs are on v8 or older. If you're one of them, here's what you're missing, and how to close the gap without the pain.

PSA: based on npm download numbers, roughly half of all Sentry JavaScript SDK installs are still on v8 or older 🫢

If you haven't seen Session Replay, structured logs, AI monitoring, and many others in your Sentry dashboard, your SDK version is probably the reason!

Going to React Miami next month?

Stop by our booth and meet us at the afterparty at Wynwood Marketplace on April 24th! More details coming soon*

See you there 😎🦩

When you're chasing a crash during dev or hunting a perf regression after launch, you need context, not just a stack trace.

Join our next live demo to see how Sentry gives you the crash context, stack traces, and performance data you need to fix issues fast 💨

Fair Source Software in the AI age AI is changing software licensing fast. Here’s why Fair Source still works for companies that want to share code without giving away the business.

Now we're taking a hard look at how AI impacts that model, and whether Fair Source still holds up (Spoiler: it does!)

Fair Source Software in the AI age AI is changing software licensing fast. Here’s why Fair Source still works for companies that want to share code without giving away the business.

Gen AI is changing a lot of things — including how we think about software licensing 🤔

Sentry has always had strong opinions on licensing, from BSD to FSL to launching Fair Source in 2024.

Choosing a JavaScript Logging Library: The 2026 Definitive Guide Pino, Winston, Bunyan, or LogTape; here's how the top JavaScript logging libraries compare so you can pick the right one for your stack

As AI-generated code becomes the norm, production-ready logging is no longer optional. But the good news is it's never been easier to set up for you and your LLM agents 🙂
