Gratz to @GregMolnar & @RaulOnRails our top 2 Sjoelen players at #RailsWorld26

[AppSignal @AppSignal]

@excid3 has taught more Rails devs to build real apps than almost anyone. We teamed up with him to add new Rails tutorials to AppSignal Intelligence, so you and your AI agent get the same guidance when debugging.

We still have room for a few more devs at our Sunset Tacos event, which we're hosting with @evilmartians in Austin next Wednesday!

Register before it's too late!

We'll bring some stroopwafels too, don't worry.

It's day 1 of ElixirConfUS, and we've got you covered with WiFi, Stroopwafels, and the best Elixir APM in town.

MCP queries your monitoring data. It doesn't collect, store, or alert. Your agent isn't watching your app while you sleep, and every event would cost you tokens.

We wrote about what MCP actually does and what still needs a monitoring tool.

[AppSignal @AppSignal]

Vibe coding makes a monitoring tool look done in an afternoon. Then you need to monitor the monitor.

We wrote about why building your own breaks down and where a managed tool actually saves you time.

Doesn't matter who wrote the code: you, Claude, or the colleague who swore RSpec covered every edge case.

What matters is that when PagerDuty wakes you at 2 am, you can fix it quickly.

Migrating your app can be scary, but it doesn't have to be.

@render makes deploying easy. Our checklist makes the move easy too, with AppSignal as your smoke alarm: it tells you the second something breaks and gives you the tools you need to fix it.

[AppSignal @AppSignal]

You prompted a Flask app into being. It worked locally, so you shipped it.

You don't know each function well enough to catch what breaks in the wild. Not your prompt's fault, not your agent's. Just a blind spot.

@quatermain32 wired the AppSignal CLI into a Claude skill. Now he types "close incident 143" and it just runs the real CLI command.

Wrote up how he built it, plus a bundled skill you can install now:

appsignal-cli skill install

Debugging used to mean tabbing through screens like you're docking at the ISS.

Now your editor can just ask AppSignal directly.

New guide: connect AppSignal's MCP server to Claude Code, Cursor, VS Code, and Zed in under 5 minutes.

We're really excited to sponsor Code Beam Europe, especially as Elixir was our first adventure outside of Ruby.

Can't wait to see people in person with some swag and stroopwafels in Amsterdam this Autumn!

[Code BEAM @CodeBEAMio]

We are thrilled to announce that @AppSignal is joining us as a D&I (Diversity & Inclusion) Sponsor for Code BEAM Europe!

They've been along for the whole ride - first APM with native Elixir support, back in 2017, built from scratch before telemetry existed.

Thanks for helping us keep the door open.

On a scale of 1-10, how fast are your Sidekiq jobs? If it's "no idea", you're not alone!

Sidekiq's faithful, but faithful isn't set-and-forget. It slows down a millisecond at a time until it doesn't, blood pressure included.

Here's why and how to fix it: https://t.co/5e9LhCgFod

Day 3 of Launch Week: Logging 📝

Logs live next to your errors, traces, and host metrics now. Query with AND/OR, JSON dot notation, and comparisons like duration_ms>2000, then turn any line into a metric or alert.

[AppSignal @AppSignal]

It's day 2 of Launch Week! Hosted MCP + new CLI make it way easier to connect AI agents to AppSignal.

OAuth gets you connected in clicks, then your agent pulls real errors, traces, logs, and metrics.

The CLI's great for fast lookups or leaner agent runs.

It's Launch Week at AppSignal. Today: @render 🚀

One-time setup gets you automatic host metrics, HTTP latency, Postgres and Key Value dashboards, plus log views - for every service in your Render workspace.

Good morning from Brighton Ruby, (thanks for organizing @andycroll!). We've got Dutch Stroopwafels (strope-waf-els), Brighton Rock, and we're giving away 3x @useTRMNL displays 😎

[AppSignal @AppSignal]

You picked your stack for how you work. Familiarity, speed, preference.

None of that carries over when an agent writes the code.

So we asked which framework an AI builds cheapest. Rails vs Django vs Laravel, every token counted.
What we found:

The 2026 Rails Community Survey is open.

10 minutes, anonymous, and the results go back to the whole community.

This year's focus: AI in Rails workflows: whether you're using it or not, your answer matters!
