BitComet

What BitComet does

BitComet, operated by the BitComet Development Group and headquartered in Changning, China, is a free C++ BitTorrent/HTTP/FTP download client distributed as freeware for non-commercial personal use, with commercial licensing available through written agreement. The core product supports modern BitTorrent protocol features including Magnet Links, HTTP Seeding, DHT network, UDP Tracker Protocol v2, BitTorrent v2, hybrid torrent formats, uTP, and UDP hole punching, alongside differentiated proprietary technologies such as Long-Term Seeding (resolving downloads stuck at 99%), Intelligent Disk Caching (hardware protection), Preview-while-Downloading, and cross-protocol downloading combining BitTorrent with HTTP, FTP, and eMule sources. The product portfolio extends beyond the main client to include BitCometLite (a customizable white-label downloader for enterprise customers, approximately 1.4MB compressed), BitCometTracker (a high-performance tracker server tested with 80,000+ torrents and 800,000+ users), WebUI (remote web-based interface with cloud connectivity), an Android companion app, and auxiliary tools (FLV Player, FLV Converter, AntiARP), plus an eMule plugin for ED2K network interoperability.

The business model is primarily freeware distribution to individual consumers, with revenue generation through commercial licensing to enterprises — most visibly gaming companies in China using BitCometLite to distribute large game clients (e.g., MOYU 2.0 distributing 18,000GB daily, Zhu Xian, Perfect World, and 20+ other titles). Go-to-market is product-led and community-driven: distribution occurs via the official website (bitcomet.com), alternative platforms (CNET Download.com, FossHub.com), BitTorrent-distributed installers, and community forums (cometforums.com), wiki documentation, and a recognized Japanese community site (jp.bitcomet.com). The software supports 53 languages and runs on Windows, macOS, Linux, and Android.

BitComet was founded in 2003, received $2 million in funding from IDG Capital in 2006, and has maintained continuous development with the latest version v2.20 released January 2026. The company is privately held with 1-10 employees, no disclosed management team, no patents, no M&A activity, and operates without institutional backing beyond the original IDG Capital investment. Customer concentration sits in two segments: a highly distributed individual consumer base (freeware) and a more concentrated enterprise gaming publisher segment that represents the primary monetization pathway.
