I.
THE NAME
& THE IDEA
A PHILOSOPHICAL STARTING POINT
Virtual Rooms
of Spir.
A place where independent thought
becomes shared possibility.
Our name is a tribute to Afrikan Spir (1837–1890), the philosopher behind Thought and Reality. His questions about identity, knowledge, and the world give our name its point of departure.
We bring our own question to the work: what becomes possible when distinct ways of thinking have a place to meet? Vrspi gives each agent a room to work, and a way to reach the others.
An imagined study in perspective.
II. / THE RUNTIME
A room of their own.
A world in common.
Keep the agents you choose. Give their work a structure.
Vrspi holds the terminals, identities, and conversations together.
Leave the view.
A thought shared.
A task advanced.
Send retained messages to named agents. Follow what’s pending, delivered, and acknowledged.

Work as a team.
Connect agents in a collaboration lobby. Messages wait for an eligible idle turn, so focused work can continue.

IV. / A PRACTICE, IN THREE MOVEMENTS
Bring them together.
Let ideas travel.
Bring your agents
Open your coding tools in dedicated panes. Vrspi recognizes supported agents and shows their current state.
Make the connection
Use “Call another agent,” connect a workspace lobby, or link agents through the CLI.
Let context travel
Send a task or a review request. The runtime queues it for the next eligible idle turn.
V. / GROUNDED IN YOUR WORLD
Your machine.
Your agency.
A native Rust runtime built for the place you already work. No Electron shell. No required external database.
Under the hood ↗01
Local by design
Your local server owns terminals, sessions, and collaboration state. Your agents still use their chosen providers.
02
Identity with a boundary
Messages belong to a specific agent instance. A replacement agent doesn’t inherit someone else’s inbox.
03
A tool you can direct
Work through the TUI, CLI, or local JSON API. Name agents, read their screens, send prompts, and wait for state changes.
What is Vrspi Runtime?
Vrspi is a terminal workspace manager and runtime for coding agents, built on Herdr. It brings persistent terminal workspaces, retained agent messages, and collaboration lobbies into one local environment.
Why the name Vrspi?
Vrspi means Virtual Rooms of Spir. The name is a tribute to Afrikan Spir, the nineteenth-century philosopher and author of Thought and Reality. For us, it suggests a place for independent thought, careful inquiry, and ideas made tangible.
Is Vrspi an AI model or a coding agent?
Vrspi manages the workspace around your agents. Bring tools such as Claude Code, Codex, or Gemini CLI, along with their own accounts and subscriptions.
Can I download it today?
Vrspi is currently in local development. Public installers, supported release platforms, and commercial pricing have not been announced. Request early access to express interest in trying the runtime.
Will messages interrupt an agent that’s working?
Automatic lobby delivery targets recognized idle agents only. Pending messages wait while an agent is working or blocked, with one automatic delivery per idle → active → idle cycle.
What survives a restart?
Detaching a client leaves the server’s terminal processes running. A cold server restart stops those processes; restoring saved state is not the same as resuming running agents. Recovery behavior depends on the development build, and message delivery should not be treated as exactly-once across a crash.
Where does my code go?
Vrspi’s runtime and local socket API run on your machine. The coding agents you choose may send code and prompts to their own providers under those providers’ settings and policies.
