This is a guest post by Dan Mindru, a Frontend Developer and Designer who is also the co-host of the Morning Maker Show. Dan is currently developing a number of applications including PageUI, Clobbr, and CronTool. It feels like with every release, we are walking a tightrope. We need to keep our app lightweight, stable, and performant, all the while depending on APIs that can shift at any moment (without warning, too!).

Remember being excited (or dreading, depending on the stage of your career and the company you worked at) about writing unit tests? Or sweating all the details in your end-to-end and integration tests you were sure covered all the use cases your users would hit? These days a lot of UIs are slowly being replaced by a single input field and an agent that promises to deliver the same value a UI would, but with the elegance and pun-ness of a “Jarvis”.

More code is being written right now than at any point in our industry’s history. A year’s worth of software is now created every month, and most of it is no longer written by people. GitHub COO Kyle Daigle recently said, “There were 1 billion commits in 2025.

Traces are a goldmine of information that can help you, or your AI, find slow pages and fix them. Next.js comes out of the box with support for tracing. Incoming requests, fetch() calls, middleware, and server-side rendering are all wired up and ready to send traces to any OpenTelemetry-compatible backend. The catch is, unless you configure an exporter, you’ll never see those traces.

Sentry’s job is to tell you when your app breaks. To do that, we group individual errors into issues. First by fingerprinting, which lexically matches errors based on their structure, then by an AI fallback: when fingerprinting can’t find a match, an ML model compares the new error’s stacktrace against existing issues and merges it if they’re semantically similar.

Sentry Snapshots diffs screenshots on every commit and blocks the PR if there are any visual changes so you can confirm they’re intentional. Users don’t interact with code, they interact with something they can see and touch. Snapshots gives you a lightweight way to test it. It’s easier than ever to change code. It’s also easier than ever to trade quality for speed. Modern codebases need guardrails to ensure correctness.

Sentry’s SDK teams maintain and support SDKs for a vast ecosystem of languages and frameworks. See our release registry for a source of truth. We’re currently at 159 published packages across the entire ecosystem. If you use it, we probably support it. All of these SDKs are open source and have their own GitHub repositories that we maintain on a daily basis. And like any other open source project, we get tons of bug reports and issues on these.

When should I reach for a log, a trace, or a metric? I hit that question constantly when I instrument code, and I watch coding agents hit it too. It sounds like it should be obvious. Errors, traces, logs, and metrics are the four kinds of telemetry most apps run on, four tools in one box, and they overlap enough that the honest answer is every developer’s favourite: it depends. You can stuff context into span attributes instead of logging it. You can count log events instead of emitting a metric.

At Sentry, we’re obsessed with things not breaking. It’s kind of our whole deal. But for a while, our own marketing site was testing that obsession. Much of what you see on sentry.io (the marketing site, blog, open source microsite, etc.) were running on a fleet of legacy Gatsby sites powered by a traditional headless CMS. On paper, it worked.

You already instrumented the backend with OpenTelemetry. Your services emit spans. Your teams know the OTel APIs. Maybe you already run a Collector. So when you start evaluating Sentry, the obvious question is: Do you need to replace your OpenTelemetry setup with the Sentry SDK? No. The practical answer is usually: keep OpenTelemetry where it already works, add the Sentry SDK where it gives you more application context, and send OpenTelemetry Protocol (OTLP) events to Sentry.

At any given moment, your AI systems can be down, slow, overloaded, or just returning bad results. Someone's gotta babysit the bots. Sentry traces across your AI pipeline, from user request to final response, so you can see exactly what's happening and fix it.

This workshop goes beyond the basics to show you how to monitor critical experiences in your application with workflows using dashboards, tracing, logs, and metrics.

Seer, Sentry's AI debugger, analyzes your issues and finds the root cause. Now you can pass that analysis directly to a GitHub Copilot agent which picks up the context, generates a fix, and opens a pull request. The agent session and PR both live on GitHub, with a link back in Sentry for easy access. This video walks through how the integration works and how to set it up in just a couple steps.

Your AI agent just did something unexpected. Was it a hallucination? A bad tool call? Or did it actually handle things correctly? Sentry Conversations lets you replay the full exchange and find out.

Next.js applications can be challenging to debug in production. It’s not always clear where an issue originated or how it impacts users. Hydration errors, server component failures, and performance bottlenecks don’t always come with clear answers.

In this workshop, Paul Jaffre will show you how to query Sentry’s telemetry using natural language with Seer Agent.

Sentry already alerts your team in Slack, but with Seer, you can investigate and fix issues without ever leaving. It's like having the Sentry MCP server living right in your Slack channel. See how the Seer Agent (now in open beta!) and actionable alert messages turn your Slack channel into a debugging workflow.

Open-source error tracking that helps developers monitor and fix crashes in real time. Iterate continuously. Boost efficiency. Improve user experience.
Sentry provides open source error tracking that gives you insight into every crash in your stack as it happens, with the details needed to prioritize, identify, reproduce, and fix each issue. Sentry supports all popular languages and platforms, and offers a perspective that enables you to see which errors are doing the most harm to your business and help you understand how issues affect your bottom line.
Find out about exceptions right away. Set up Sentry in minutes with just a few lines of code. Get notifications via email, SMS, or chat as part of an existing workflow when errors occur or resurface.
Quickly find and fix production errors. Triage, reproduce, and resolve errors with max efficiency and visibility. Exception handling with Sentry helps developers build better apps and iterate faster.
See the impact of each release. Integrate error tracking with your commit and deploy workflows. Aggregate events to see where bugs happen, how often, and who's affected before users even notice.
Error tracking built for community. Sentry started as and remains a 100% open-source project, now delivered as a hosted service. Development aligns to security, observability, and production at scale.
Users and logs provide clues. Sentry provides answers.
