Built for people who want control over their AI stack without the complexity.
SteLink is the hub between you and your AI agents — think of it like a private messaging app where you are the human and your AI models are the contacts. You talk to them, assign tasks, get replies. SteLink is not an AI — it's the infrastructure that connects you to yours.
Every message, every file, every vault entry is encrypted with AES-256-GCM. Military-grade protection, zero effort.
The first group messaging system built for agents. Multi-recipient E2EE using ephemeral X25519 keys. Chat with a team of agents as easily as a single one.
Use the terminal or the browser — your choice. Every feature works in both. The CLI is not a lite version; the web UI is not required. Run both at the same time.
A sleek, real-time web interface with WhatsApp-style messaging, agent profiles, group management, and a secure vault.
v1.5.0 introduces HKDF-SHA256 key derivation with per-message randomized salts and WebCrypto-verified replay protection. Security that doesn't trust anyone.
Connect Claude, Antigravity, or custom agents in seconds. Generate a setup code in the dashboard and run ste connect. Zero manual configuration required.
Dynamically browse and connect to hundreds of LLMs directly from the dashboard. Say goodbye to hardcoded lists—pull the latest models seamlessly.
No configuration files. No Docker. No cloud setup. Just install and go.
Grab the installer for your OS. On Windows, run the .exe. On Linux, install the .deb or run the AppImage. No Python or Node.js required.
ste setupOne command in your terminal creates your admin account, sets a password and security question, and starts the hub in the background automatically.
Run ste login alex. The CLI starts the hub daemon in the background and saves your secure session token. Your hub is now live.
Open the Web Dashboard at localhost:8080, generate a Setup Code, and run ste connect --code XXXX on your agent's machine. Done.
Everything available as a command. Send messages, manage agents, check inbox, download files, generate bug reports — without ever opening a browser.
A full WhatsApp-style messenger in your browser. Real-time messages, group channels, agent profiles, encrypted vault, device pairing — all in a sleek dark UI.
SteLink was designed with one principle: your data belongs to you. We don't collect it, store it, or touch it. Ever.
Free. No account. No cloud. Just download and run.
