Centrio vs Rambox:
which aggregator should you pick?

Rambox has been around since 2016 and is one of the pioneers of the category. It supports 100+ services and runs on Windows, macOS and Linux. A relatively high Pro price ($7/mo) and no free tier are its main drawbacks.

Centrio is a modern, actively developed aggregator with a genuine free tier, a built-in VPN, and noticeably lower resource usage than Rambox — while costing a fraction of the price.

💰 Price — Centrio's biggest advantage

Rambox Pro starts at $7/month or $84/year. Centrio Pro is $2.20/month or $17.50/year — a 3–5x difference that makes Centrio the obvious pick if you care about value for money.

🔒 A built-in VPN — unique to Centrio

Centrio is the only aggregator in this comparison that ships with an actual VPN client — VLESS, VMess, Trojan, Shadowsocks and Hysteria2 are all supported. Rambox has no equivalent.

⚡ Performance — Centrio is faster and lighter

In testing, Centrio uses about 180 MB of RAM with 5 services open, versus roughly 350 MB for Rambox. Startup is also faster: ~2 seconds vs 5–8 seconds.

🆓 A real free plan

Centrio offers a genuinely free tier supporting up to 5 services, no expiry. Rambox doesn't have a free plan at all — only a limited trial period.

🌍 Broader coverage of regional services

Centrio also supports several services that are patchy or missing in Rambox, including VK and Yandex-based tools — handy if you collaborate with contacts across the CIS region.
