MZBaseProfiles on our own engine
Each profile runs MZBrowser, our Chromium-based engine, with a consistent Persona or the Real machine. Folders, tags, bulk create, import and export.
Early access · Windows first Run hundreds of accounts
Run hundreds of accounts
like one well-run team
MZBase gives every account its own browser profile, with its own fingerprint, proxy and data. Then it automates the work with workflows and AI agents. Your profiles stay on your computers.
- Free for one computer
- No credit card
- Your data stays with you
Everything one account needs, times a thousand
Six building blocks that share the same profiles, accounts, proxies and permissions.
Proxies and proxy router
HTTP, SOCKS5, providers, Change IP and IPv6 from your own line. Pools pick a free proxy at every start, never share an exit IP, and keep the country.
Workflows
A drag-and-connect canvas with 220+ nodes, schedules, webhooks and per-node logs. Scripts keep Playwright syntax but run on our stealth driver.
AI agents
Bring your own brains: Claude Code and Codex in the agent hub, your own API keys through the AI gateway, or local models on your GPU.
Phones
Android phones on your PC or your own Linux server, each with its own device identity, driven by the same workflows. Early preview.
Team server
Host your own team server on Cloudflare or Docker: members, sharing, profile locks and encrypted sync between computers.
MZBrowser engine
A fingerprint that holds together
A browser profile is only as good as its weakest signal. MZBrowser is our own engine, so every layer agrees with the others.
Persona or Real machine
Compose a full device from a seed, or run on this computer as it is. Both on the same build.
Follows the proxy
Time zone, language, WebRTC IP and location follow the profile’s proxy, checked before every start.
Stealth automation
Our own CDP driver never turns on the signals pages look for, works in isolated worlds and types and moves like a person.
Pinned versions
Each profile keeps its engine version, so its fingerprint does not change under you after an update.
Automation
Automate it once, run it on every account
One capability layer: every action is a workflow node, an agent tool, an MCP tool and a command line call.
Workflow canvas
Triggers, branches, loops, data tables, retries and partial re-runs, with templates for common farm jobs.
Playwright-style scripts
Write page, locator and click like you already do; the same script runs on our driver, not raw Playwright.
Action sync
Drive many windows from one: clicks, typing in any language, scrolls and tabs replayed on every profile.
Local API, CLI and MCP
Start profiles and run workflows from your own tools over a key-protected API on 127.0.0.1, or the mzb command.
AI agents
Your brains, your keys, your machines
Agents use the same profiles, accounts and permissions as people, and anything that posts, sends, buys or deletes starts as a draft.
Agent hub
Claude Code and Codex in a chat and terminal view, with MZBase’s MCP attached and approvals for risky actions.
AI gateway
Many providers and models behind one place: your keys, routing, logs and cost per run.
Local AI
Run language, image and speech models on your own GPU through native runtimes you choose. Nothing is bundled.
MZBase never extracts, stores or proxies your AI subscription sign-ins.
Local first
Your profiles never pass through us
On your computer
Use MZBase on one computer with no server and no account. The free plan works offline.
On your own server
For teams, the team server and its storage are yours (Cloudflare or Docker). MZBase runs only licensing and updates.
Encrypted and locked
Profile bundles and the vault are encrypted. A profile opens on one device at a time, with admin takeover.
Built for people who run more than one account
Account farmers and MMO teams
Hundreds of isolated accounts, proxies that never collide, and jobs that run every day on their own.
Sellers, marketers and agencies
Shops, ad accounts and social pages for many brands or clients, shared safely across a team.
Vibe coders
A terminal, AI agents and an API around real browsers: describe the job, let the agent build the workflow.
Questions
Which operating systems are supported?
Windows 10 and 11 (64-bit) first. macOS and Linux come later.
Do I need an account?
You need an MZBase account to download the app, start a trial or use a license. The free plan itself needs no sign-in and works offline on one computer.
Does MZBase see my profiles, cookies or passwords?
No. Profiles live on your computer or on the team server you host. Cookies and passwords are always stored encrypted. MZBase’s servers handle accounts, licenses and updates only.
Can I use my own proxies?
Yes. Add HTTP or SOCKS5 proxies, connect providers, rotate IPs with Change IP, make IPv6 proxies from your own line, and group them in router pools.
Can I automate without writing code?
Yes. Build workflows on the canvas from ready nodes and templates, or ask an AI agent to build one. Scripts are there when you want them.
Is it allowed on every platform?
You are responsible for following the law and the terms of the platforms you use. MZBase is a tool for managing your own accounts; see our Terms of Service.
