Genspark AI Browser

I have tested version 1.5.421 and it's based on Brave and Chromium 135. Brave is licensed under MPL-2.0, which requires to release the modified source code. However Genspark Browser is closed source, thus violating the MPL.

Next, it requires to sign up for a user account and accept a vague privacy policy, even to use a local LLM.

It has ollama and node.js server with playwright built-in and the bundled web extension is a communication bridge. The local chat UI is at genspark://on-device-free-ai, but it is very limited - it doesn't use agentic features. Bummer.

Beware: it's closed source. For privacy, we need an open source, local alternative to Gemini in Chrome, Perplexity Comet, Fellou or this. Something like NanoBrowser with in-browser LLM inference.
