OmniInbox — Modular Multi Messenger & CRM Platform

Hey Indie Hackers! 👋

I’m a software developer and I’m selling OmniInbox — a production-ready team inbox platform with a modular channel abstraction layer. While Telegram and WhatsApp are fully pre-built out of the box, the system is engineered to easily plug in ANY messaging channel or custom API (Instagram, Discord, Viber, etc.).

I love engineering products from scratch, but marketing isn't my strongest suite. I'm looking for an growth-minded buyer to take this validated asset and scale it.

📊 Key Financials & Metrics

• Asking Price: $10,000

• Current Revenue: $600/mo MRR (Generated organically by 3 active teams with zero marketing budget)

• Running Costs: Max $30/mo (No expensive paid APIs or dependencies, yielding a 95%+ net profit margin)

• ROI Potential: Competitors charge $25/account. OmniInbox is priced at $13/account. A single client with 20 accounts brings $260/mo, ensuring a rapid payback.

🛠️ Robust Tech Stack

• Backend: Python 3 (Flask, Gunicorn) + Node.js (Express, Baileys for WhatsApp integration)

• Telegram Integration: Telethon (MTProto API) + python-telegram-bot

• Database: PostgreSQL

• Frontend: Vanilla JS, HTML5, CSS3 (Optimized for Web, PWA, and Telegram Mini App)

• Infrastructure: Linux, Caddy (HTTPS reverse proxy), systemd, DuckDNS

📦 What You Get for $10,000

• 100% Code Ownership: Full frontend and backend source code (including Telegram Mini App, PWA, and APK-ready configs).

• Core Modules: Embedded CRM, automated broadcast engine for campaigns, quick replies, and dual English/Russian language support.

• Production Copy: The existing 3 teams stay on my private instance. You get a clean, deployment-ready copy with migration scripts and full DevOps documentation.

• 2 Weeks of Direct Support: I will personally help you with setup and free minor requested adjustments (e.g., final wrapping into APK or finishing custom auth).

Building this modular architecture from scratch would take 4-6 months and over $30,000 in engineering budget. You can acquire this fully functional, market-tested codebase today for a fraction of that cost.
