Building TeamSync: An Open-Source Collaborative Office Suite for Enterprises

Garima Mahajan — Tue, 17 Feb 2026 02:26:02 +0000

We just open-sourced the editor behind TeamSync — our AI-powered collaborative workspace platform. If you've ever wondered what it takes to build a real-time collaborative office suite (think Google Docs, but self-hosted and enterprise-grade), this is your chance to dive into the code.
🛠️ What We Built
• TeamSync Editor: A fully collaborative Word, Presentation, and Sheets editor — built on Collabora Online and LibreOffice technology.
• Real-time multi-user editing: Multiple people can edit the same document simultaneously with live cursors and conflict-free merges.
• Enterprise-ready: Designed for on-premise deployment with air-gapped support — perfect for government, defence, and regulated industries.
• Open source: Licensed under MPL-2.0 — you can fork, modify, and deploy it yourself.

**💡 Why We're Sharing This
**Most collaborative office tools are closed-source SaaS platforms. That's fine for most use cases — but what if you're working in a highly regulated environment where data sovereignty is non-negotiable? What if you need full control over your infrastructure?
That's the problem we built TeamSync to solve. And now we're opening the code so the developer community can learn from it, contribute to it, and build on top of it.

⚙️ The Tech Stack
• C++ (editor-source): The core collaborative engine — forked from Collabora Online, heavily customised for our use cases.
• JavaScript (teamsync-editor): Frontend interface for Word, Presentation, and Sheets editing — clean, fast, and extensible.
• WebSockets: Real-time synchronisation between clients and server.
• LibreOffice: Document rendering engine — fully compatible with .docx, .pptx, .xlsx formats.

🚀 What You Can Do With It
• Deploy your own collaborative office: Host it on your own servers — no vendor lock-in, no data leaving your infrastructure.
• Extend the editor: Add custom plugins, integrations, or AI features on top of the base platform.
• Study real-time collaboration: Learn how operational transformation (OT) and conflict resolution work at scale.
• Contribute: Found a bug? Have an idea? PRs are welcome.
