October 16, 2026 began like any other day at Fly.io (meaning, we were anticipating only a medium amount of chaos). By that evening, we had patched and rebooted our entire fleet in response to a Linux kernel bug.

In Databricks’ State of AI Agents 2026 report, there’s a chart from Neon’s telemetry that’s somehow both mind-blowing and unsurprising. In October 2023, AI agents created 0.1% of the databases on Neon.

I have unkind things to say about people who make their own pasta. Here, I’ll only use them as an example of how not to think when you’re building infrastructure.

Sprites are disposable cloud computers. They appear instantly, always include durable filesystems, and cost practically nothing when idle.

We’re Fly.io, a public cloud platform that is both our favorite way to put an app on the Internet and our favorite way to safely let a frontier agent coding harness cook.

Building agents is fun. Rebuilding agents that break themselves… less so. A lot of Fly people are building agents with less of a penchant for self-destruction by teaching their agents to do anything risky in a Sprite.

I’m Ben Johnson, and I work on Litestream at Fly.io. Litestream is the missing backup/restore system for SQLite. It’s free, open-source software that should run anywhere, and you can read more about it here.

We’re Fly.io, and this is the place in the post where we’d normally tell you that our job is to take your containers and run them on our own hardware all around the world.

The state of the art in agent isolation is a read-only sandbox. At Fly.io, we’ve been selling that story for years, and we’re calling it: ephemeral sandboxes are obsolete. Stop killing your sandboxes every time you use them.

Some concepts are easy to grasp in the abstract. Boiling water: apply heat and wait. Others you really need to try. You only think you understand how a bicycle works, until you learn to ride one.

Fly.io transmogrifies Docker containers into Fly Machines: micro-VMs running on our own hardware all over the world. The hardest part of running this platform isn’t managing the servers, and it isn’t operating the network; it’s gluing...

The $FLY Airdrop is live! Claim your share of the token powering Fly.io’s global network of 3M+ apps and (🤮) own a piece of the sky! We know. Our Twitter got owned. We knew within moments of it happening. We know exactly how it happened.

I’m Ben Johnson, and I work on Litestream at Fly.io. Litestream makes it easy to build SQLite-backed full-stack applications with resilience to server failure. It’s open source, runs anywhere, and it’s easy to get started.

I’m an audiophile, which is a nice way to describe someone who spends their children’s college fund on equipment that yields no audible improvement in sound quality. As such, I refused to use wireless headphones for the longest time.

Trust calibration is a concept from the world of human-machine interaction design, one that is super relevant to AI software builders.

Recently, I suggested that The Future Isn’t Model Agnostic, that it’s better to pick one model that works for your project and build around it, rather than engineering for model flexibility.

Your users don’t care that your AI project is model agnostic. In my last project, I spent countless hours ensuring that the LLMs running my services could be swapped out as easily as possible.

I’m Chris McCord, the creator of Elixir’s Phoenix framework. For the past several months, I’ve been working on a skunkworks project at Fly.io, and it’s time to show it off.

With Fly.io, you can get your app running globally in a matter of minutes, and with MCP servers you can integrate with Claude, VSCode, Cursor and many more AI clients. Try it out for yourself !

A heartfelt provocation about AI-assisted programming. Tech execs are mandating LLM adoption. That’s bad strategy. But I get where they’re coming from.

Agile Web Development with Rails 8 is off to production, where they do things like editing, indexing, pagination, and printing.

We’re Fly.io, a public cloud that runs apps in a bunch of locations all over the world. This is a post about a gnarly bug in our Anycast router, the largest Rust project in our codebase. You won’t need much of any Rust to follow it.

Litestream is an open-source tool that makes it possible to run many kinds of full-stack applications on top of SQLite by making them reliably recoverable from object storage.

This is a blog post. Part showing off. Part opinion. Plan accordingly. The Model Context Protocol is days away from turning six months old. You read that right, six months old.
Fly.io's own blog, found on fly.io by the daily check; not reviewed yet.
