Neural Engineering System Terminal
Five AI coding agents, scattered across your machine.
NEST holds the helm.
NEST is a local-first control plane for professional AI coding agents: a Rust server as the single source of truth, a CLI, and a React PWA. Run Claude Code, Codex, Cursor Agent, Gemini, and OpenCode from one hub — drive them from the web PWA, a Telegram Mini App, or any browser. 50+ companies already self-host NEST today.
// One server. One session log. Every agent accountable to it.
Built by those who run agents in production
The same control plane FACTA runs on its own agents. Not a wrapper — a real Rust server.
- 5 agents live today
- Rust server · single source of truth
- PostgreSQL persistence
- Per-agent permission gates
- Audit trail on every session
- BYOK — no lock-in
- 50+ companies self-hosting
The problem
Every agent runs in its own silo. None answers to one helm.
Claude Code, Codex, Cursor, Gemini, OpenCode — each a powerful agent, each its own process, its own context, its own unaccountable loop. You switch between terminals, lose the thread between sessions, and no single log holds what any of them actually did.
A professional AI coding workflow needs one source of truth — not five tabs and a prayer.
The platform
Three steps. One control plane.
Install the Rust server, sync your agents to it, and govern every session from one log.
Five agents live today — Claude Code, Codex, Cursor Agent, Gemini, OpenCode. Self-hosted, free.
01
Install
Run the Rust server locally or in Docker. PostgreSQL persists sessions, messages, and events. One binary, one source of truth.
Learn more
02
Sync
Point the CLI at your agents. NEST speaks Socket.IO, SSE, and REST so every agent reports to the same session log — terminal, PWA, or browser.

The agents — 5 live today + Voice
Every agent you already run, on one hub
Five agents ship today, each live and wired to the same Rust server. Voice drives them all from one console.
Who it's for
A specific answer for every operator
From the solo dev in the terminal to the platform engineer routing every line — one server, one log.
Why different
Five agents in five silos.
Five agents on one helm.
Three ways teams try to run AI coding agents — and where each one breaks.
| Bare terminals | Agent-specific UIs | NEST | |
|---|---|---|---|
| One session log across all agents | no | no | yes |
| Single source of truth (Rust server) | no | no | yes |
| Per-agent permission gates | no | partial | yes |
| Audit trail on every session | no | no | yes |
| Drive from web, Telegram, or any browser | no | no | yes |
| Mobile oversight of running agents | no | partial | yes |
| Survives an agent crash | no | no | yes |
Enterprise
Your security team approves from the start.
Self-hosted Rust server, PostgreSQL persistence, per-agent permission families, and a full audit trail. BYOK. No training on your data.
By the numbers
One server. Every agent accountable.

Why $49, and why per key
The API key is the unit of value — so it's the unit of price.
One key maps to one operator's identity and one seat on the server. You pay for the agents that actually work, not for seats that sit idle.
Land with 3–5 keys, expand as the helm proves its worth.
How teams grow into NEST
From a free download to org-wide oversight
Four steps — and you only pay at the step where it already pays for itself.
This is land-and-expand — the pricing is built for it.

FAQ
Frequently asked questions
Everything you need to know before getting started.
Is NEST really free?+
Yes. NEST is free and self-hosted. Clone it and run the Rust server today — no card, no account. 50+ companies already self-host it in production.
Which agents are live today?+
Five: Claude Code, Codex, Cursor Agent, Gemini, and OpenCode. All live, all wired to the same Rust server. Voice drives them all from one console.
What's the Rust server for?+
It's the single source of truth. Every session, message, and event flows through it and persists in PostgreSQL — so nothing is lost between terminals or crashes.
Can I drive agents from my phone?+
Yes. The React PWA mirrors the server, and a Telegram Mini App lets you watch and drive sessions from anywhere.
Do you train on my data?+
No. We never train on your data. BYOK and a self-hosted Rust server are available for full sovereignty.
What are per-agent permission families?+
Each agent runs under a mode family you define — what it may touch, what it may run, what it may send. The gate opens only when the permission says yes.
Can I cancel anytime?+
Yes. Cancel Team keys anytime. Export your audit trail anytime. No lock-in.
Is there an enterprise tier?+
Yes — Custom, priced on your pilot's ROI. Self-hosted or dedicated cloud, BYOK, dedicated success engineer, Docker images on your registry.
