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

Source: Dev.to

🛠️ 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 — ideal 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 works for many scenarios, but in highly regulated environments data sovereignty is non‑negotiable. TeamsSync solves that problem by giving you full control over the infrastructure. By open‑sourcing the code we hope the developer community can learn from it, contribute, and build on top of it.

⚙️ The Tech Stack

• C++ (editor‑source) – Core collaborative engine, forked from Collabora Online and heavily customised.
• JavaScript (teamsync‑editor) – Front‑end 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 on your own servers, eliminating vendor lock‑in and keeping data in‑house.
• 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 or have an idea? Pull requests are welcome.
