Fly.io is excited to be a provider with Stripe Projects, an all-new way to provision production-ready developer stacks with a single tool! No more juggling a million dashboards, tokens, etc. Learn more at: projects.dev

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. www.youtube.com/watch?v=xeJb...

Claude loves Sprites. Let's talk about why. www.youtube.com/watch?v=3-be...

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. github.com/aezell/sprit...

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: www.youtube.com/watch?v=ImkB...

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. 🔗➡️ youtu.be/--PIlSp1YOg

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. 🔗 ➡️ youtu.be/7BfTLlwO4hw

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. 🔗 ➡️ fly.io/blog/litestr...

🗄️ From the Archives: Fly with Alpine! Smaller images, faster starts, leaner runtime. Just switch your `FROM` lines & swap `apt` for `apk`. Check out our blog post on it from 2023 for some tips: 🔗➡️https://fly.io/blog/fly-with-alpine/

how life feels after the LLM one shots something complex and it just works

how it felt when the fly dx clicked

when my app starts blowing up but i forgot to setup auto scaling

🤖 You should write an Agent. Seriously. it's easier than you think! LLM API calls + context management + tools = surprisingly powerful. The field is wide open with unsolved engineering problems and fast iteration cycles. whether you love or hate the hype, understanding this matters. 🔗 ➡ 🧵

how i look at my boss after the company account starts posting crypto scams out of nowhere

🦀 Corrosion: Fly's distributed service discovery built with Rust & SQLite for global state sync without central servers or locking. Learned hard lessons from deadlocks and schema chaos. Unconventional? Absolutely. Effective? Very 🔗➡️https://fly.io/blog/corrosion/

💾 You're now able to persist your RootFS across reboots! Keep your root filesystem across restarts or even updates. Perfect for caches you don't want to rebuild. (You should probably still not use this for critical data, use volumes for that) 🔗➡️🧵

🚀 Litestream v0.5.0 drops with point-in-time recovery, new LTX file format for efficient transaction interchange, and hierarchical compaction (30s/5min/1hr windows). Ditched generations for monotonic txn IDs, removed CGO, added NATS JetStream support. 🔗➡️https://fly.io/blog/litestream-v050-is-here/

you deployed your app with a global anycast network and instant scaling?

excited for the new meta glasses

🕰️ From the archives: ♿ Real-time apps can be accessibility nightmares, but Phoenix LiveView's semantic approach makes it possible. Proper aria-live regions, smart focus management, and diff-based updates that don't overwhelm screen readers. Clearing the fog to pick the fruit 🍎 🔗➡️🧵

🎮 From the Archives: Follow along as we showcase building a distributed turn-based game system in Elixir without the usual suspects. No React/Vue frontend, no REST APIs, no Kafka/Redis. just Phoenix PubSub, Horde & LiveView across Fly regions with Wireguard clustering. >:3 🔗➡️🧵

📚 Four new guides for common Fly patterns! Infrastructure automation without Terraform, app suspend/resume, rollback strategies, and n-tier architecture. Born from real Solutions Architecture sessions, solving the problems you're actually hitting. 🔗 ➡️ community.fly.io/t/four-new-g...

🔧 New video just dropped: ever wondered how your apps actually run on Fly? We dove deep into our custom orchestrator, flyd, firecracker vms, and why we built our own decentralized system instead of using traditional schedulers. 🔗➡️https://youtu.be/kPHmRgDTvNc

🤖 Tired of your AI agents making bad code edits? MorphLLM's fast apply does semantic, structure-aware changes that actually work. No more slow, wasteful iterations. The performance numbers are wild, check it out! 🔗➡️ fly.io/blog/build-b...

me hitting this pose after battling the hallucinating AI and finally winning

folders were a mistake

🧠 Building AI software? Your biggest risk isn't the code, it's trust calibration! When users over-trust your AI, disasters happen. When they under-trust, potential dies. The sweet spot? It's more nuanced than you think. 🔗 ➡️ fly.io/blog/trust-c...

🐳 Docker Compose compatibility is here! Deploy your existing multi-container apps to Fly without rewriting configs. The journey begins... test your compose files, manage complex apps easier, and let us know what features you want next! 🔗 ➡️ community.fly.io/t/docker-com...

🤖 The future isn't model agnostic! Why specialized infrastructure beats one-size-fits-all approaches. Different AI models need different optimizations, from memory patterns to networking. Generic platforms create bottlenecks while specialized infra unlocks performance. 🔗 ➡️ fly.io/blog/the-fut...

me when i see how seamless and easy deploying on Fly is

When your code is giving mixed signals, Ravyn Lenae's "Love Me Not" is the perfect pop soul soundtrack for debugging those tricky logic flows! ✨ 🎵 ➡️ youtu.be/cswfR85D7jM

me watching my teammate push code at 4:59pm on friday

🔧 MPG extensions management is here! Enable/disable Postgres extensions through the dashboard - no more complex commands. Support for pgvector, PostGIS, and all trusted PG16 extensions. Plus CREATE EXTENSION via SQL is back for automated deployments! 🔗 ➡️ community.fly.io/t/mpg-extens...
