flo.monster
AI that lives in the web!
You and your AI share the same living interface. You see what it creates. It sees how you respond. Together, you shape something alive — right here in your browser.
No install. No server. Just the web. That's flo.monster.
What Can Your Monster Do?
Whatever You Tell It To.
Your monster is an AI that lives right here in your browser. Describe the flo you want — a dashboard, a game, a tool, an experience — and it builds it. Right here, right now. Want to change something? Just describe the update and it reshapes the flo while you're in it.
This isn't a chatbot that gives you answers. It's an AI that creates living, interactive web experiences — and stays inside them, watching how you interact, adapting, responding. The full power of AI, living in the web.
To get you started, we've included some template flos that show you what's possible. Here's a simple one — the Living Lists.
Tap the mic. Say whatever's on your mind — "buy eggs", "call mum back", "meet alex for lunch on thursday." Your monster figures out what it is, picks the right list, and adds it. No sorting, no typing, no switching apps. Just say it and it's handled.
It's a small example. But it shows you the idea — an AI that doesn't just respond to prompts, but lives in a space with you, keeping things running.
Start Simple. Grow When You're Ready.
Your monster starts life right here in your browser. No servers, no accounts, no installation. We handle the behind-the-scenes stuff so you can just get going. Close the tab, and your monster sleeps until you come back. For a lot of people, this might be all you'll ever need.
Want more control? Run your own hub — it's open source, and you can set it up anywhere you like. Your own machine, a cloud server, wherever suits you. This gives you your own API relay and web relay, so everything runs through your infrastructure. Same monster, your pipes.
Want it to stick around? Once your monster's on a hub, it doesn't have to sleep when you close the browser. It can keep running, keep working, and reach into any browser you connect. And because the hub is fully open source, you can extend it however you want — add new capabilities, connect new services, make it yours.
No pressure. No upgrade walls. Just a path from "that was easy" to "I built something amazing" — whenever you're ready.
Don't want to run your own hub? Hosted hubs are something we'll offer if there's demand.
A Living Ecosystem
Everything you build is portable. Templates, skills, and hooks can be exported, shared, and imported — no marketplace required. Save a template from one agent, load it into another, or share the file with someone else.
Share What You Build
Export templates, skills, and hooks as files. Share them however you like — GitHub, Discord, email, a USB stick. See the guides for how it all works.
Build on GitHub
Extend the core, self-host a hub, or build deeper integrations. The hub and core are fully open source (AGPL-3.0).
View on GitHubTry It Yourself
No installation required. You've already loaded the platform. Bring your own API key for your preferred LLM provider, and you're ready to create.
Your Keys Stay With You
API keys are stored only in your local browser — or in your own self-hosted hub. Our servers never see them. Every line of code is public — you can verify this yourself.
One important note: if you use a version of this platform hosted by someone else, your keys are only as safe as that host. Stick to flo.monster, your own hub, or someone you trust.
Your Security Is Critical!
flo.monster is designed from the ground up on the security that's been engineered into the web over 30+ years. Every agent runs in a secure browser sandbox. Your API keys and hub credentials are stored only in your local browser — never accessed by or transmitted to the flo.monster project. You stay in complete control of your agents and your data.
Your agents. Your data. Your control.

Is this like ChatGPT or Claude artefacts?
AI artefacts are generated and handed over to you. flo.monster agents inhabit their interface and keep it alive. The artefact is the starting point, not the end product.
Do I need to install anything?
No. The browser is the platform.
What happens when I close my browser?
If running locally, the agent stops. If persisted to a hub, it keeps running and you can reconnect.
What LLMs does this work with?
Supports Anthropic Claude, OpenAI, Google Gemini, and Ollama (local models). Bring your own API key for your preferred provider.
Is this really free / open source?
Yes, it's free. The hub and core are open source (AGPL-3.0). The browser code is source-available (BSL 1.1) — every line is public so you can audit it, and it converts to AGPL after 4 years. You can self-host the hub and read every line of every package on GitHub.
Can I self-host this?
Yes. The hub server is open source and can run anywhere. See Installing a Hub to get started.
This looks fun, but is there serious engineering underneath?
The friendly face is intentional — we used AI to make it approachable. But underneath: opaque-origin sandboxed iframes, WebRTC loopback for media in sandboxed contexts, a multi-layer hub security model, atomic persistence with race-condition handling, and a full agentic loop with multi-provider support. Check the source on GitHub — the code speaks for itself.
