⚡ OPEN-SOURCE • 100% FREE • LOCAL-FIRST AUTOMATION

Build a Personal Zalo Chatbot
& Automate Customer Replies with AI

Q: What is Zalo-Flow and is it completely free?

Zalo-Flow is an open-source software (MIT License with Commons Clause) that is 100% free forever. It turns any standard personal Zalo account into a 24/7 automated AI assistant without requiring expensive Zalo Official Account (OA) business registration or monthly subscription fees.

Q: Will my personal Zalo account get banned using this chatbot?

Zalo-Flow features an immutable 3-layer anti-ban architecture: Token Bucket Rate Limiting (minimum 3-second delay, maximum 20 messages/minute), Self-Echo Shield preventing conversational feedback loops, and an Inbound Flood Detector that temporarily mutes incoming storms. It operates strictly in-thread and behaves like a genuine human user.

Q: Does Zalo-Flow read or steal my passwords and private messages?

No. Zalo-Flow is 100% local-first and completely open-source for public audit on GitHub. All session tokens and AI keys are encrypted with military-grade AES-256-CBC and stored strictly within a local SQLite database on your machine. Zero data is sent to external cloud servers.

Q: Does the bot stay active when my computer is shut down or sleeps?

Because Zalo-Flow runs locally on your computer, the Node.js process pauses when the computer shuts down or goes to sleep. For 24/7 continuous operation, set your PC power mode to 'Never Sleep' while plugged in, or deploy Zalo-Flow via Docker on an affordable Linux VPS.

Q: Which AI models does Zalo-Flow support?

Zalo-Flow supports multiple leading AI providers out-of-the-box: Google Gemini (Gemini 1.5 Flash, 2.5 Flash), DeepSeek (Chat, Reasoner), OpenAI (GPT-4o, GPT-4o-mini), and local offline LLMs running via Ollama.

Turn your standard personal Zalo account into an intelligent 24/7 sales and customer support assistant. Powered by Gemini & DeepSeek AI, automatic contact phone extraction, personalized remarketing, and 3-layer immutable anti-ban protection.
