Pros & Cons
Centrifugo
Pros
Free, Apache 2.0-licensed core with no per-connection or per-message fees
Production-proven at scale by companies including VK, Badoo, ManyChat, and Grafana
Supports multiple transports and scaling backends rather than locking teams into one stack
Broad official SDK coverage across web, mobile, and backend languages
Cons
Requires engineering effort to deploy, secure, and integrate versus a plug-and-play hosted API
Centrifugo PRO pricing is not publicly listed, requiring direct contact for enterprise features
Self-hosted operation means the adopting team is responsible for uptime, scaling, and monitoring
No official company headquarters or large support organization behind the open-source core
One Time Secret
Pros
Free plan is fully functional, including a custom domain and REST API access
Open source with the option to self-host for full data control
Over a decade of continuous operating history since 2011
Simple, no-friction experience: no account required to view a shared secret
Straightforward, transparent paid tier at a flat monthly price
Cons
Encryption is server-side, not fully zero-knowledge, so the operator's server briefly handles plaintext
Free plan expiration is capped at 14 days
Custom branding and unlimited domains require the paid Identity Plus tier
Built for short text secrets, not designed for sharing large files
No native mobile apps; it is a web-based tool only
Use Cases
Centrifugo
In-App Chat & Live Comments — Development teams use Centrifugo to power real-time chat and live comment features without depending on a hosted third-party API.
AI Response Streaming — Applications use Centrifugo to stream partial LLM/AI responses to clients as they are generated.
One Time Secret
Sharing credentials with teammates or IT support — Send passwords or access credentials internally without leaving them in permanent chat or email history.
Sending API keys or database passwords to clients — Developers and agencies share one-off credentials with clients or contractors via a link that disappears after use.
One-off sharing of sensitive personal information — Individuals send private information such as account numbers or personal details securely to another person.
