Single Sign-On is now generally available in Oh Dear, on every plan. Your team signs in with the credentials they already have, and you manage access from one place: your identity provider.

AI coding agents like Claude Code and Codex are becoming a real part of developer workflows. They don't just write code, they call APIs, interpret responses, and take action based on what they find. That means the quality of your API responses directly affects how useful an agent can be. We've shipped a series of improvements to the Oh Dear API with this in mind. Every change helps humans too, but we specifically optimized for how agents consume and reason about data.

AI coding agents are getting good at calling tools. Claude Code, Codex, and others can run shell commands, parse JSON, and reason about the results. But they need to know what tools are available and how to use them. That's what skills are for. A skill is a small package of documentation that teaches an AI agent how to use a specific tool. We've built one for Oh Dear.

Oh Dear's dashboard now supports dark mode. You can choose between light, dark, or system-based theming, and your preference is saved to your profile so it follows you everywhere.

Oh Dear has always been a desktop-first tool. If you checked your monitors on your phone, you'd get the full desktop layout squeezed into a tiny screen, with lots of horizontal scrolling and tiny tap targets. That's fixed now. Every page in the app works on mobile.

Your domain is on a spam blocklist. Password reset emails aren't arriving, order confirmations land in spam, and customers are complaining that "your site doesn't work." By the time you hear about it, the damage has been building for days. We've shipped DNS blocklist monitoring to catch this early. Oh Dear now checks your domain against 11 major blocklists and notifies you the moment you're listed, with direct links to get removed.

Our documentation, FAQ, and blog posts can now be served as clean markdown to AI agents. Send Accept: text/markdown or append.md to the URL, and you get structured content instead of a full HTML page. It worked great in development. Then we deployed, and two separate caching layers broke everything.

This is the final part of our 3-part series on SQL performance improvements. In part 1, we covered how to identify slow queries. In part 2, we explored how to fix them with indexes. In this post, we'll share how we prevent those performance issues from ever reaching production again. A few weeks ago, we massively improved the performance of the dashboard & website by optimizing our SQL queries.
