Facts, with sources on each project page

Runs on my machine?Differs

Yes, runs inside your own Chrome or Edge browser

Yes, Python scripts or a local Gradio web UI; Docker image also available

Self-hosted with Docker (recommended) or a local dev setup

Hosted by the vendor

Code licenceDiffers

Apache-2.0

Model weights licenceDiffers

No separate model weights; you bring a cloud API key or a local model

No separate model weights; you bring your own model API key or a local Ollama model

No separate model weights; you bring model API keys or host a model yourself (vLLM supported)

—

Commercial useDiffers

Yes, Apache-2.0 code; model terms depend on the provider you choose

Yes, MIT code; model and search provider terms apply separately

—

Paid services needed?Differs

Nothing paid with a local model (Ollama, LM Studio); cloud model APIs are optional and paid per use

An LLM API key is needed for the main examples; an Ollama example runs a local model; other tool keys are optional

Needs a model (API key or self-hosted) and a web search provider such as Tavily or InfoQuest; self-hosted fetchers exist

Subscription

HardwareDiffers

Any machine running Chrome or Edge with a cloud model; local models work best for simple tasks and need a 16k+ context

Not documented; cloud model use needs only Python; browser tasks need a multimodal model

Minimum 4 vCPU, 8 GB RAM, 20 GB free SSD for local use (more for Docker or shared servers); a local LLM is sized separately

—

Operating systemsDiffers

Any desktop OS with Chrome or Edge; Firefox and Safari not supported

Windows, macOS and Linux; Python 3.10 to 3.12

Linux recommended for servers; macOS and Windows (Git Bash) for development or evaluation

—

Setup effortDiffers

Easy; install from the Chrome Web Store and connect a provider

Medium; pip/uv/conda install plus .env API keys, or a prebuilt Docker image

Medium; make setup writes config, then make docker-start; needs Docker Compose v2.24+ and model and search keys
