Run open LLMs on your own computer
VirexaLLM is the desktop runtime for open-source language models. Llama, Mistral, Phi-3, Gemma, Qwen, DeepSeek — served from localhost:1775/v1 with the OpenAI API you already use. Private by default. macOS, Windows, Linux.

How it works
From install to local inference in four moves
Drop the VirexaLLM app on your machine.
Signed installers for macOS (Apple Silicon + Intel), Windows, and Linux. Under 100 MB, no dependencies.
One-click download from the curated library.
Llama 3, Mistral, Phi-3, Gemma, Qwen, DeepSeek-R1 — each with a quantization tuned for your CPU and RAM.
Use the built-in chat UI, or serve the local API.
Flip the server on and http://localhost:1775/v1 starts speaking the OpenAI format to any tool you already use.
Nothing ever leaves the device.
Air-gap mode blocks every outbound call. Zero telemetry. Reproducible builds. Open weights you can inspect.
A desktop LLM runtime. Everything you need. Nothing you don't.
Local inference, a polished chat UI, and an OpenAI-compatible API server — shipped as one signed binary so your team stops wrangling Python environments.
Run LLMs on your laptop
Download a model, double-click, start chatting. No cloud account, no API key, no data leaving your machine.
OpenAI-compatible local API
Expose a localhost endpoint at http://localhost:1775/v1. Point the OpenAI SDK, Cursor, or LangChain at it and ship.
One-click model library
Browse, download, and hot-swap curated open models — with Q4_K_M, Q5_K_M, and Q8_0 quants picked for your hardware.
Private by default
Zero telemetry option. Air-gap mode disables every outbound call. Your prompts stay on your disk, forever.
Built-in chat UI
Desktop app with conversations, file attachments, prompt templates, side-by-side model comparison, and instant model switching.
Lightweight everywhere
CPU-first with Metal, CUDA, and Vulkan acceleration when present. Ships as a small signed binary, not a 4 GB Electron tumor.
Drops into the tools you already use
Point the OpenAI SDK, Cursor, continue.dev, LangChain, or the Vercel AI SDK at http://localhost:1775/v1 and your app is now running on a model on your machine. No rewrites.
Local LLMs, done properly
Cloud APIs leak your prompts. DIY runners leak your weekend. VirexaLLM delivers local inference as a product a non-infra engineer can ship with.
vs Cloud LLM APIs
Keep sensitive prompts off the wire. Ship features that work offline, on a plane, behind a customer firewall.

Lighter footprint, faster cold start, and a proper local API server designed for production tools like Cursor and continue.dev.
Full comparisonOpen model families and the tools you already use
Curated open-weight models you can download in one click — served to every SDK and IDE that speaks the OpenAI format.
Privacy your security team will actually sign off on
Nothing leaves the device by default. No cloud attack surface. Open weights, reproducible builds, and code-signed installers shipped from day one.
VirexaLLM for Teams
Deploy VirexaLLM across your fleet
Push the same model set to every workstation, lock access by device, and run inference behind the firewall. Admin console included — air-gapped environments supported.
Fleet model pushes
Ship a curated model list to every workstation. Version-pin, block unapproved weights, and update on your schedule.
Per-device licensing
One admin console for seats, machines, and model access. Offboard a laptop and its models follow — or stay revoked.
Air-gapped installs
Side-load signed bundles onto isolated networks. No phone-home, no update checks, no cloud dependency of any kind.
Regulated industries
Purpose-built for healthcare, legal, finance, and defense workflows where prompts cannot cross the device boundary.
Your laptop is the server now
Download VirexaLLM and run Llama, Mistral, Phi-3, Gemma, or Qwen locally in minutes. Free desktop app for macOS, Windows, and Linux — your prompts never leave the device.
