Ask anything...

Hand work over instead of operating a tool.

Less chatting, more done. Hand off the task, carry on, collect the result. You focus on what matters, your agent does the rest in the background.

Works around the clock

At set times or nonstop in the background, even while you're away. The result is ready when the run ends.

Long-term memory

The essentials from whole PDFs, even hundreds of pages long, and from your conversations. The knowledge stays, ready whenever a task needs it.

Works as a team

Large tasks, split into steps and run in parallel. Via an agent-to-agent protocol, also alongside Claude, Codex or OpenCode.

Teaches itself new tools

It runs them, reads the results and adjusts until it can use them on its own, custom ones included.

Your machine, your server, your call

Local model, your own server, or one API key for every provider. You decide where the data lives and which model does the work. No per-seat subscription.

Local-first AI agents

What it means to run an agent on your own machine, and why local-first matters for privacy, cost and control.

Read the explainer

Local-first by design. You decide where VAF runs.

VAF runs on your machine, on your own server, or as a framework inside your code. Memory and keys live where the agent runs.

For power users

Desktop app

Install it, sign in, and the agent is in its own window.

Your data and keys stay on your machine
Local models, or one API key for everything
Schedules, memory and tools built in

For teams & companies

Self-host it

Install it, share it, and VAF runs on your server at your own address.

One host serves the whole team over HTTPS
Separate accounts with isolated memory
No per-seat subscription

For developers

Build on the framework

Import it as a Python library for your own automations, agents and software.

The agent on the go.

More than a chat. Your agent, on the go. Web search, automations and a notification when something's done. History and memory are stored on your device, protected by your phone's encryption.

Your own agent, three lines in.

The desktop app runs on this framework, and you build on the same primitives. Install it from PyPI and build your own automations, agents and tools on top.

Provider-agnostic. The same code runs a local GGUF model or any API provider; swap with one config line.

Bring your own tools. Subclass BaseTool or wire in MCP servers, and the agent picks them up at startup.

Your license, your product. Plugins, tools and workflows built on the public interfaces may ship under your own terms.

Every model your agent needs, behind one key.

VAF needs models for text, vision and speech. Normally that means an account with every provider, every key wired in by hand, a separate invoice per provider and no combined view. The Veyllo API bundles that into one key and one bill.

One key instead of many. Every model VAF uses, behind a single API. No separate accounts or keys at each model provider.

No models to host yourself. No GPUs, no self-run model servers. Veyllo handles compute and model hosting.

Built for production. Keys, rate limits and usage metering from day one.
