GM! Battling bugs with the devkit on Windows this morning. Wish me luck!
PixieOS
npub1u7m9...akzy
Tiny. Magical. Fun. A powerful webOS, designed for accelerated AI app development. The fastest and easiest way to build and share apps that run everywhere with no install! Nostr, identity, storage, UIKit — batteries included. Zero Big Tech.
GM! It’s alive!
It’s called Pixie Agent and when you toggle it on from Settings, then every app gets an agent button.
Agents have access to our full catalog of tools to see what you see.
The next step is to build out the file system so that can edit and build the app completely within the OS without ever touching your computer’s disk.


New look at the agent UI. Trying to get it as simple as possible. There is a little agent button at the top of each app. Toggles the chat thread.


I’m working on the UI for Pixie Code. I’m thinking that every app should get an agent button. You ask your agent to make changes then click View, which auto compiles and shows you the latest. I also thought about having built in testing so that your agent can write tests as they go.


GM! Excited to start the new sprint. I really want to make it easy for anyone to build and share an app using a pixie app, without being required to download or setup any other software. Just open pixie, add agent API key, build and share.
In 0.2.0, key tentpoles:
- infrastructure for PixieCode
- nostr and social app
- QA and security
Here’s a WASM app that demonstrates Pixie’s internal runtime and memory management.
Argon2 is often used to slow down attackers when brute forcing passwords by forcing them to allocate a large amount of memory.
An OS needs to be able to handle memory hungry apps without crashing. Here’s how you can watch this on Pixie:
Open multiple argon2 apps, set each to 1 GB and then start them simultaneously. Watch as Pixie schedules and allocates device memory to each.
If you open System Monitor, you can watch the memory allocation as it happens.

PixieOS — Shared App
Open this link to boot PixieOS and install the shared app.
New build is out (v0.1.9) 🎉
If you’re using the devkit, back up your apps and remind your agent to use ‘npm run update’.
If you’re using it from pixieos.io, just hit reload and you should be prompted to update.
Your old messages channels won’t work. Update and reconnect.
Any bugs or issues, please let me know. 🙏
New features:
- app notifications and badges
- invite code to Messages
- share app with link
- sync contact profiles
GM! Later today or tomorrow, I’m planning to release 0.1.9. It’s a breaking release so you will need to update your local devkit after. Just wanted to give a heads up. I’ll provide more details once it’s ready.
Thinking about the next release. Our North Star should be to make it as easy as possible to build a new app, and to invite others and share it.
Since this is an OS, we should be able to do all app development from within the OS. You shouldn’t need to download and install anything. Launch Pixie, open the PixieCode app (add an API key) and instruct your agent to create an app and starting editing. Unfortunately I don’t see how we can avoid the API key friction. 🤔
I think we should be able to create, edit, build and share an app all from within the OS.
GM! Nothing better than a morning with several quiet hours ahead to build. Working through the cleanups for 0.1.9. Thinking ahead about priorities for 0.2.0.
This is one of the powerful benefits of building AI agent tools directly into PixieOS. When you’re debugging, the agents can see what you’re seeing and analyze the code directly. In this case, I told the agent to inspect the window the raccoon is looking at.
@Matt thank you for the bug report. Found and fixed.


The new staging build for 0.1.9 is up. I would appreciate any help with testing. Link below.
1) open the dev link in separate browsers
2) try generating a Pixie code on one browser, in the other browser create a message channel. Message back and forth. Send apps to each other.
3) when you receive a message when the app is closed, you should see notifications
4) Change your profile in one account (Settings | Profile), and watch it update on the other account. Should update in Contacts and Messages.
5) end apps with links. Right click or long press on the app from the desktop.
- should work on mobile, desktop, tablets.
If you see bugs or if something doesn’t make sense, please let me know. Thank you!🙏

Here it is! This is a shared game on staging. Hopefully it works when you click the app to play. If you see any weird stuff, please let me know.

I would love to bring something like this to Pixie. Pixie instances already use key pairs as ID. I’m wondering if we could add this as another connection service like how we do with Nostr, Feedsync and Blossom. We could make it easy for apps to connect with each other. If anyone can help with this, please reach out!
