[ local · isolated · private ]
An open-source AI coding agent that runs entirely on your hardware, inside an
isolated container, with --network=none enforced by the OS kernel.
Your source code physically cannot leave the machine — not a promise, a constraint.

Most AI tools promise "we don't train on your data." SITU makes exfiltration technically impossible. By default, the container runs with --network=none — no network interface exists at all. The agent cannot call home, contact an API, or send a single byte to the outside world, regardless of what the model or user instructs. Not a policy. A namespace constraint the kernel itself enforces.
"Not a privacy policy. A kernel constraint."
Every SITU session run is an isolated, short-lived container. When you exit, the pod and all its containers are automatically destroyed — no logs retained, no conversation history stored, no residual state. Your context, prompts, and partial outputs vanish completely. What happens in SITU stays in SITU. Full stop.
"The session ends. So does everything in it."
SITU only sees what you define. Nothing else exists inside the container. Your home directory, SSH keys, credentials, environment variables, and the rest of your filesystem are completely invisible to the agent. You define the blast radius before the session even starts — and the container boundary enforces it.
"It sees exactly what you show it. Nothing more."
SITU runs on any machine that can run an AI model: a developer MacBook on CPU, an AMD workstation using ROCm, or an NVIDIA GPU rig with CUDA. No cloud account required. No token quota. No rental fees. SITU starts its own secure llama container, but you can also point it to your own llama.cpp instance or LM Studio — the choice is yours. Better hardware means larger models and faster inference, and the ceiling is yours to raise.
"Your hardware. Your model. Your rules."
The agent has no internet access unless you deliberately switch to NETWORK mode. Sensitive work stays isolated. When you need to fetch documentation, you make a conscious, explicit choice.
Every container definition, every shell script, every line — published under the MIT License. Real transparency means the code speaks for itself. Read it, verify it, run it - securely.
No per-seat license, no monthly billing, no token quota. The only cost is the hardware you already own — run unlimited sessions on unlimited projects, forever.
Three simple steps. The entire stack stays on your machine.
situ Anywhere. Start Coding.SITU follows you wherever you work. No configuration needed per project. No plugin to install in your editor. Just a terminal and your project directory.
Free, open-source, MIT-licensed. Up and running in 15 minutes — no cloud account, no subscription, no surprises.
