Ship local-first AI features without the API bill

VirexaLLM gives AI startups and indie developers a local OpenAI-compatible server, a curated catalog of open-weight models, and a chat UI — all running on the laptop you already own. No keys to rotate, no per-token spend, no cloud round-trips.

To First Token

Install, load a model, start building

The runtime you'd otherwise duct-tape yourself

Local server, model catalog, chat UI, and fleet controls — one install.

Drop-in OpenAI API

Keep the SDK you already ship with. Change one base URL to http://localhost:1775/v1 and you're running against an open-weight model on your own hardware.

No API bills, ever

Prototype, iterate, and demo without watching the meter. Your inference costs flatten to whatever power your laptop was already using.

Works offline

Coffee shop, airplane, locked-down client network — VirexaLLM keeps running. No auth pings, no telemetry, no dependency on someone else's uptime.

Curated model catalog

Llama, Mistral, Phi-3, Gemma, Qwen, DeepSeek — one click to download, with quantization presets tuned for your CPU, GPU, or Apple Silicon.

Private by default

Every prompt, every document, every snippet of code stays on the device. Ship features with sensitive data without a DPIA attached to each release.

Tiny footprint

A signed native binary — not a 4 GB Electron shell — with a fast cold-start and a chat UI that doesn't fight your window manager.

Ship to users in a day, not a quarter

Change one base URL to http://localhost:1775/v1. Keep your streaming handlers, your tool calling, your function schemas. Start calling Llama 3, Mistral, Phi-3, and Qwen from the same code path you use for GPT.

How indie builders ship on VirexaLLM

Install

Download the signed binary for macOS, Windows, or Linux. Pick a model from the catalog.

Point

Set OPENAI_BASE_URL=http://localhost:1775/v1 and start shipping features against real open-weight models.

Distribute

Bundle VirexaLLM into your app's install flow, or point customers at their own instance. Zero infra on your side.

No lock-in, by design

We chose OpenAI-compatible and open-weight on purpose. Every line of code you ship against VirexaLLM works directly against api.openai.com — or any other compatible endpoint. Stay because it's private and free, not because switching hurts.

Privacy posture your first enterprise customer will love

Local inference, signed binaries, and air-gap mode — out of the box.

100% Local Inference

Zero Telemetry

Frequently asked questions

Will VirexaLLM lock us in?

No. We're OpenAI-compatible on purpose, and we only ship open-weight models. If you leave, you change a base URL back — your code and your model choices come with you.

How fast can we ship?

Install, pick a model from the catalog, and point your SDK at http://localhost:1775/v1 — most developers are generating tokens inside 10 minutes.

Can we swap models without redeploying?

Yes. Change the model name in the request, or switch the default in settings. The OpenAI-compatible surface stays identical.

Does it really work offline?

Yes. Once a model is downloaded, VirexaLLM never needs the internet again. Air-gap mode blocks network access entirely for paranoid builds.

Which models are supported?

Llama 3.x, Mistral, Mixtral, Phi-3, Gemma, Qwen, DeepSeek, and any GGUF you bring yourself. Vision-capable models and embedding models are included.

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.
