As answered by people managing KeyCDN and ReplyStack.
ReplyStack's answer:
ReplyStack was born from a simple frustration: existing review management tools either cost hundreds of dollars per month or only work with a handful of platforms. After seeing local businesses struggle to keep up with reviews scattered across Google, TripAdvisor, Booking, and Facebook, I built a solution that works everywhere — by combining a lightweight Chrome extension with a centralized dashboard. No complex integrations, no enterprise pricing, just a practical tool that helps SMEs protect their online reputation.

ReplyStack is currently in early launch phase. We're onboarding our first customers from the restaurant and beauty salon industries in France.
ReplyStack's answer:
ReplyStack is the only review management tool that combines a Chrome extension with a SaaS dashboard. This hybrid approach lets businesses respond to reviews on platforms that don't offer APIs — like TripAdvisor, Booking.com, and Yelp — something competitors simply cannot do. Instead of expensive API integrations or risky scraping, our extension works directly in the browser where business owners already manage their reviews. It's legal, reliable, and works everywhere.

Small and medium businesses that depend on online reviews but lack the time or budget for enterprise reputation management tools. This includes restaurant owners, hotel managers, e-commerce sellers, beauty salon operators, healthcare providers, and auto repair shops. Our typical user manages 1-5 locations, receives reviews on multiple platforms, and wants to respond professionally without spending hours each week on it.

Migrate to a good host like Krystal.uk. The difference is night and day. Then, host the file with a CDN like https://bunny.net or https://keycdn.com. Source: over 4 years ago
Use any hosting on the sidebar, and a CDN like bunny or key. Otherwise you'd get banned from a web hosting plan, either from DMCA or auto file uploads. CDNs are designed for constant file uploads and usually warn you if anything illegal... Source: over 4 years ago
