The Sprite storage stack is WILD
We want to see all the cool things you've been building with Sprites!
Join us on Discord and brag about your stuff: discord.gg/sprites
We made our sandboxes stateful. Here's how.

we love to hear it!
Claude loves Sprites. Let's talk about why.

Last note:
If you were building a code runner like this For Real, you'd be a lot smarter about it. You'd stick to one Sprite per user, or perhaps project. No shared Sprites between customers, tho. (That would be rude)
To learn more, checkout sprites.dev !
a simple prompt describing the code runner seen before
Secondly, we built this whole thing with a single prompt.
We can do this with confidence because Sprites were designed to be the perfect place for Claude to just go nuts. No need to micromanage. Just give it a task, and then go make some lunch.
It's that easy.
Built the world's simplest code runner in 5 mins with Sprites.
This is doubly cool. First off, how it works:
User writes some scary JavaScript, which then gets run in a new Sprite. Sprites are literally built for running random code, so bring on the footguns.
🧵
Sprites make it easy to connect stuff on the internet.
Take Slack bots: easy to build, annoying to hook up locally and test.
Sprites are first-class citizens of the internet, so you can just build your bot on one, get a public URL, and boom: it's plug-n-play ready.
If you spend a lot of time coding with AI on your computer, do yourself a favor and visit sprites.dev by @fly.io
Is that a TUI for visualizing your sprites MADE IN A SPRITE? Yes, yes it is.
It lets you see all the sprites in your org, which ones are running, and organize them to get a better sense of which sprites work together.

Sprites are stateFUL sandbox environments with 100GB of storage. Spin them up in milliseconds, boot up Claude, and get to vibin'.
They are durable, performant, and persistent.
They are disposable and cheap.
They are the perfect playground to run your weird AI code.
Stateless containers have long reigned supreme in the development world, and for good reason! But they aren't ideal for running AI generated code.
See, Claude doesn't want ziploc bags. It wants a computer with disk storage and such.
That's where Sprites come in.
Deli cups are also reusable *and* disposable. Throw them in the dishwasher over and over OR chuck them out when the fridge needs a purge.
You know what ALSO appreciates reusable, disposable, and multi-purpose boxes?
AI agents.
Deli cups are just better, more rigid ziploc bags.
Store leftovers in them. Store liquids in them. Stack them. Use them as organizers. Use them as plant pots. Use them as measuring cups.
Hell, use them as CUPS.
Anything a zip can do, a deli cup can do better.

We've been yappin' about Sprites a lot, but something we haven't been yappin' about are...
✨DELI CUPS✨
🧵
Running Claude inside a Sprite is cool and all, but so is, you know, *using an IDE*. So we made a VS Code extension for Sprites! Checkout the demo:

We made "ball-point disposable computers" by committing three heresies: Killing user container images, running orchestration inside the VM, and backing disks with S3. The result? Instant boot, auto-sleep, and zero dockerfile misery. Machines are for servers; Sprites are for everything else.

🤖 We made a thing that handles real AI workflows called Sprites. Watch the video where Claude builds features, breaks things, fixes modals, adds color-coded graphs, and switches themes. All while the developer, @anniesexton.com does her makeup.

We offer 30 days of free support when you start out, just in case :p
We made a thing called Sprites that lets you run AI code safely. Watch Chris create sandboxes in seconds, let agents install packages freely, then restore to checkpoints when things go sideways.

how im feel after the first successful deployment of 2026
the moment you're using fly
🚀 Just dropped: Litestream VFS. Query SQLite databases directly from S3 with zero download penalty. It uses HTTP range headers for lazy fetching and LTX for compaction, enabling instant startup even for large databases.

me running out of bed having figured out the bug in the codebase in my dream
feeling called out this year...
me when I sense the PagerDuty alert right as im settling down on Friday night
