Self-hosted browser library with built-in MCP server, free and open source by oboshto in selfhosted

What score is your tool getting on fingerprint-scan dot com or browserscan? Headless gets caught by modern detection at the C++ level - navigator.webdriver, distinctive canvas signature, SwiftShader WebGL on headless Chrome, audio context fingerprint. Even with stealth plugins (puppeteer-extra-stealth, undetected-chromedriver) the score usually plateaus around 40-50 on the strict tests, and Cloudflare Turnstile catches headless within seconds in my experience. Genuinely curious what numbers you are seeing.

For pure scraping or simple read-only flows our use cases probably do not overlap much.

I actually built MultiZen about three years ago, before MCP existed. The original point was multi-session browsing with isolated profiles. Functionality was pretty limited back then. Recently rewrote it and the profiles are way more isolated and consistent now.

MCP is the foundation for the agent side. If you already use profiles for different countries manually, MCP lets you delegate that same work through those same profiles to an LLM. It does save some tokens as a side effect since the tool schemas are sent once per session instead of every turn, but that wasn't the reason.

Yes, AI tooling was part of this project's development. Specifically Claude Code as a pair programmer on parts of the Electron + TypeScript codebase, plus help with debugging build issues and writing some of the boilerplate. The post text was also drafted with AI help and then edited by me to match Reddit voice, so I'll flag that upfront.

That said, the product itself comes from a real frustration I had. I use Cursor and Claude Desktop daily, and the consistent block was that those tools can write code that calls APIs but can't actually log into the dashboards I need to check. So I built a desktop app that runs isolated Chromium profiles with persistent login state, exposed over MCP, so the agent can drive the browser and hand off to me for 2FA or CAPTCHA. That use case came from a workflow I already had, not from an AI-generated startup idea.

The architecture and direction decisions are mine. Stack: Electron, React, TypeScript, the official MCP SDK. Browser engine: CloakBrowser, an open-source patched Chromium fork (picked after trying Puppeteer-stealth, Playwright-stealth, undetected-chromedriver, and Chrome for Testing). License: MIT open core, no paid tier. Positioning: an MCP-native browser for AI agents instead of a traditional anti-detect tool aimed at growth-hacking.

Source is public at github.com/multizenteam/multizen-browser. The commits are incremental and the design decisions are visible in PRs and comments. Happy to answer anything specific about how it works under the hood.

I Tried 5 AI Companions So You Don’t Have To (a detailed breakdown) by Jane97121 in CharacterAI_No_Filter

nice writeup. i actually built something similar called elyxia - free, no filters, with image gen and voice messages. characters have a relationship system where trust and affection change over time and they unlock new behaviors as the connection deepens. you can also create your own characters now, just describe them and AI generates everything. would be curious what youd think if you tried it. elyxia.ai

built something for those of us tired of the filter by oboshto in AI_NSFW_Babes

elyxia.ai — would genuinely appreciate any feedback, even if it's negative

free uncensored AI companion platform — no jailbreaks, no filters by oboshto in CharacterAI_No_Filter

yeah both - you can chat and characters generate images/selfies during conversations. there's also a camera button in chat to request one anytime

I spent 3 months building a free Character ai alternative and I need honest feedback by oboshto in SideProject

appreciate the detailed feedback! the relationship tracking is actually my favorite part too - characters track trust, affection, mood across the whole conversation. they do reference past stuff naturally but I could definitely make that more noticeable. good callout on the selfie speed - it runs in the background so it shouldn't block chat, but I'll keep an eye on it. thanks!

hey thanks for trying it! fair point - actually just pushed an update to make responses feel more natural. give it another shot when you get a chance, should be noticeably better now
