Big-AGI: Chat With Several AI Models at Once (GitHub, Scanned)

A self-hostable AI chat workspace that asks several models at once and merges their answers.

✅
Scan: safe. Nothing malicious. The official prebuilt Docker images send anonymous usage telemetry to the project's Google Analytics, which the docs disclose; build from source to send nothing. Scanned Oct 26, 2026; the full report is below.

Big-AGI is a chat interface for AI models that you run with your own API keys. It connects to OpenAI, Anthropic, Google, DeepSeek, OpenRouter, local servers such as Ollama and LocalAI, and many more, and keeps your conversations in the browser. On top of normal chat it has personas, voice input and output, image generation, web search with citations, PDF import and a request inspector that shows exactly what was sent to each model.

Its signature feature is Beam: send one question to several models side by side, then merge the best parts of their answers into one. For checking facts or comparing how models handle a hard problem, that is quicker than juggling tabs. It is built as a fast Next.js web app, MIT-licensed, and updated within days of new model releases.

The limits: you pay each provider for what you use, since the open version has no models of its own. The hosted big-agi.com has a free tier and a $10.99 a month Pro plan for syncing across devices; self-hosting gives you the open version without sync.

Who it is for

People who already pay for API access to more than one AI provider and want one workspace for all of them, and teams who want a self-hosted chat front end they control.

Getting started

1. Run the prebuilt Docker image (see the telemetry note below)

docker run -d -p 3000:3000 ghcr.io/enricoros/big-agi

2. Or build and run from source (needs Node.js)

git clone https://github.com/enricoros/big-AGI.git && cd big-AGI && npm install && npm run build && npx next start --port 3000

Open http://localhost:3000 and add your API keys in the model settings. You can also use the hosted version at big-agi.com without installing anything.

Safety scan

We cloned enricoros/big-AGI at commit cc29d9d on Oct 26, 2026 and ran the checks described on the GitHub Tools page: credential patterns, decode-and-execute code, install-time scripts, committed binaries, risky CI workflows, every host the code talks to, known vulnerabilities in pinned dependencies, and project hygiene. A person read every hit. This is what we found.

  • No secrets, no suspicious code patterns, no committed binaries and no bare-IP URLs in about 218,000 lines, mostly TypeScript.
  • docs/deploy-analytics.md states that official prebuilt images report page views and feature-usage events, without prompts or conversation content, to a Google Analytics property for self-hosted deployments. The ID is baked in at build time, so passing an environment variable to docker run does not turn it off; building from source without it does. PostHog support exists too, but only when a deployer sets its key.
  • One install hook: package.json runs prisma generate after npm install, which generates database client code and is standard for Prisma projects.
  • package-lock.json covers 867 npm packages with one critical advisory (DOMPurify 3.4.14, a sanitiser bypass in its template-safe mode) and 70 high ones, most of them axios 1.13.2. Worth watching on a public deployment; less pressing on a private one.
  • Four workflows, none using pull_request_target; 7 of 9 third-party actions pinned to a commit. Security policy and Dependabot present; no CodeQL.

Questions

Is Big-AGI free?

The open-source version is MIT-licensed and free to self-host. You pay the AI providers for usage with your own API keys. The hosted big-agi.com has a free tier and a Pro plan at $10.99 a month that adds sync across devices.

What is Beam in Big-AGI?

Beam sends the same prompt to several models at once, shows their answers side by side, and can merge them into one combined answer. It is useful for comparing models and catching an answer that only one of them gets wrong.

Does Big-AGI work with local models?

Yes. It connects to Ollama, LocalAI, LM Studio and other OpenAI-compatible servers, so you can use it with no cloud provider at all.
