Tachyon is a cloud sync tool focused on protecting PC game saves. Its goal is to prevent players from losing progress due to crashes, device changes, mod experiments, or accidental operations. Through its Windows client, it automatically scans the system, identifies save locations for 5000+ games, and performs backup, sync, and restore tasks in the background.
Based on the available description, Tachyon’s core modules include automatic game detection, real-time cloud sync, timeline management, backup and restore, and sync conflict handling. It supports games installed via Steam, Epic Games Store, GOG, and DRM-free setups. The timeline feature is a key differentiator: it lets users manage separate playthroughs, mod experiments, or recording checkpoints independently, making it suitable for players and creators who frequently need to roll back progress.
The product is currently in Beta. The official website clearly states that it is free, requires no credit card, and involves no commitment. The Terms of Service also state that the service is free during Beta, but features may change, and there is no SLA, with no guarantee of uptime, performance, or data availability. Pricing for the official release, plan tiers, storage quotas, and payment methods have not yet been disclosed.
The main advantage is its simple workflow: install it, play games, and restore or sync when needed. For ordinary players, it is easier than manually locating save files and configuring cloud storage. For mod users and video creators, the timeline and rollback features are especially valuable. The drawbacks are also clear: it currently supports Windows only, while Linux and Mac are merely planned; security and compliance disclosures are limited, with only “secure cloud storage” mentioned; and the Beta terms explicitly warn of possible downtime and data inconsistency, while disclaiming responsibility for data loss. As a result, it should not be treated as your only backup solution.
Tachyon is suitable for heavy single-player gamers, PC players who frequently switch devices, mod testers, and creators who need to return to specific story points to record footage. It is less suitable for teams that require enterprise-grade permissions, audit logs, APIs, or self-hosting. The available text does not mention access conditions from mainland China, and cloud sync stability, account registration, and future payment methods remain unknown. Alternatives include Steam Cloud, built-in cloud save features from game platforms, general sync tools such as OneDrive/Dropbox/Google Drive, or local backup solutions.
