Bitrix24 Open Source (2026)

They rewrote the database layer to work with PostgreSQL instead of MySQL. They stripped out the license keys. They built a simple, brutalist API where the bloated REST client used to be. They replaced the proprietary map service with OpenStreetMap.

The old Bitrix24 company sent a cease-and-desist letter. But their lawyers quickly discovered a problem: the original open-source license, which they themselves had released a decade ago, was irrevocable. The code was free. Forever.

The login screen was familiar, but different. The "Bitrix24" logo was replaced by a stylized anvil—the symbol of Lumen Forge. She typed her credentials.

"We need to upgrade to the 'Professional' tier," her boss, Mark, sighed over his shoulder. "That’s another five hundred a month. Just for exports." bitrix24 open source

She closed her laptop and walked outside into the morning sun. The servers hummed quietly behind her, free as the air. And somewhere in a corporate boardroom, the executives of the old cloud empire wondered, for the first time, if locking the door had only taught everyone how to pick the lock.

For two weeks, Lumen Forge’s garage looked like a mission control center. Elara and two interns, Leo and Maya, forked the ancient code. They called it

The breakthrough came on a rainy Tuesday. Maya, a wizard with front-end frameworks, managed to extract the live-chat widget and reroute it through their own Matrix server. "No more middlemen," she grinned. They rewrote the database layer to work with

Mark was skeptical. "What about updates? Security patches?"

She pushed the LumenForge OS repository to a public Git server.

"We are the updates," Elara replied. "We're a cooperative. We don't need a vendor; we need ownership." They replaced the proprietary map service with OpenStreetMap

It was a nightmare. The original open-source version lacked the polished modules of the modern SaaS product. There was no telephony integration, the mobile app was broken, and the permissions system was a labyrinth of spaghetti logic.

The migration night was tense. At 2:00 AM, Elara flipped the DNS. The office router, now a local server running LumenForge OS, hummed to life. She opened her laptop.

Elara watched the pull requests flood in. LumenForge OS wasn't just a clone. It was better. It was a community.

She was the CTO of "Lumen Forge," a scrappy cooperative building solar-powered IoT devices. They believed in open hardware, open data, and transparent systems. But their internal operations ran on Bitrix24’s free cloud tier—a brilliant, sprawling beast of a platform that had slowly become the nervous system of their startup. It had everything: tasks, chats, documents, a CRM, a website builder. Everything except freedom.
