VT Code, inside Glueprint.
An open-source coding agent with LLM-native code understanding and robust shell safety. Supports multiple LLM providers with automatic failover and efficient context management. Glueprint runs VT Code over the Agent Client Protocol it already speaks — adding live sessions on every device, approvals from your phone, parallel worktrees, schedules, and memory.

What is VT Code?
VT Code is an open-source, MIT-licensed Rust coding agent by vinhnx, built for long-running autonomous workflows with OS-native sandboxing. Its codebase spans roughly 30 crates and uses Ratatui for an interactive terminal UI. It integrates 21-plus LLM providers including Anthropic, OpenAI, Gemini, Mistral, Qwen, OpenRouter, and local inference via Ollama, LM Studio, and llama.cpp. It supports MCP in client and server modes plus open standards such as Agent2Agent, and offers an Agent Skills framework.
- Rust agent across roughly 30 crates
- OS-native sandboxing with subprocess isolation
- 21-plus LLM providers, cloud and local
- Plan-build-evaluate full automation mode
- MCP client and server, plus A2A support
Best for Developers wanting a sandboxed, autonomous Rust agent with broad provider choice.

How Glueprint runs VT Code
VT Code connects over the open Agent Client Protocol — one generic adapter implements the protocol's client side, so VT Code gets the same surfaces as every other harness:
Glueprint spawns VT Code, not a fork
Glueprint finds the VT Code binary you installed and spawns it, then speaks the Agent Client Protocol — JSON-RPC 2.0 over stdio — to drive it. Same CLI, same authentication; Glueprint just wraps the session.
Output streams as structure
Message chunks, tool calls, and tool-call updates from VT Code arrive as protocol notifications and render as the same live, typed timeline every Glueprint session gets — watchable from desktop, browser, or phone.
Permission requests become approval cards
When VT Code asks to write a file or run a command, the protocol's permission request surfaces as an inline approval card on whatever device you're holding. Approve, deny, or auto-allow per tool.
One adapter, the whole fleet
Because VT Code speaks ACP, adding it is a catalog entry, not an engineering project — the same adapter runs every other agent in the registry, so you can tile them side by side.
What VT Code gains inside Glueprint
Everything below works with the VT Code CLI you have today — no migration, no new account for the model, no lock-in. Uninstall Glueprint and your terminal workflow is exactly as it was.
Live sessions on every surface
Watch every VT Code prompt, tool call, and diff stream in real time — desktop, web portal, iOS and Android. The session runs on your machine; the view follows you.
Approve from your phone
Permission prompts arrive as approval cards wherever you are. Kick off a refactor at your desk, approve the file writes from the couch.
Parallel sessions across worktrees
Run several VT Code sessions side by side, each in its own git worktree, with diffs, history, and a three-pane conflict resolver alongside.
Mix harnesses in one mosaic
Tile VT Code next to Claude Code, Codex, and the rest of the ACP fleet in the Command Center. The protocol differs; the surface doesn't.
VT Code as a persistent assistant
Promote it to an assistant: persona, constitution, long-term memory, and a daily journal on disk, loaded into every wake.
Routines on a schedule
Wake it on cron: triage the inbox every 30 minutes, sweep PRs at 9am, run the nightly cleanup. Quiet hours and watermarks prevent re-fires.
Analytics per harness
Messages, sessions, and output tokens computed from session logs — compare VT Code against Claude Code, Codex, and your other ACP agents.
Encrypted to the relay
Remote viewing rides AES-256-GCM envelope encryption. The relay routes; it cannot read.
VT Code + Glueprint, asked plainly
Can I run VT Code with Glueprint?
Yes. VT Code is registered in the official Agent Client Protocol registry, and Glueprint implements the protocol's client side. It spawns the VT Code CLI you already installed and drives it over JSON-RPC 2.0 — adding live sessions, inline approvals, worktrees, and remote control.
Do I need a separate VT Code subscription or API key?
No. Glueprint doesn't resell model access. VT Code authenticates exactly the way its vendor designed — its own login, subscription, or API key. Glueprint spawns the binary and speaks the protocol; it doesn't sit between you and the model provider.
Can I run VT Code from my phone?
Sessions always run on your machines — a laptop, a desktop, or a server with the headless daemon. The iOS and Android app streams VT Code sessions live, lets you send follow-ups, and handles permission approvals from anywhere.
Can I run VT Code next to Claude Code and Codex?
Yes — that's the point. Each harness is an adapter; sessions from all of them tile into the same Command Center, share the same task boards, and roll up in the same per-harness analytics.
Is my session content private?
Yes. Remote viewing routes AES-256-GCM-encrypted envelopes through the relay, which stores a wrapped key it cannot open — decryption happens on your devices. On the free local tier, session content never leaves your machine at all. See security.
