🌐Overseas CDN Rankings — 2026 Annual CDN Top 100

💡 CDN Buying Guide for 2026

This ranking follows the TG4G composite scoring system across 5 dimensions: performance (25%) / value (20%) / China availability (20%) / reputation (20%) / support (15%) — see the methodology. Based on the data profile of this period's Top 100, here are 4 practical tips for 2026 CDN buyers:

• Look at the composite score, not a single metric — the Top 10 average 9.0+, but none lead on every dimension; a value-leader may score only 1 star on China access, while a China-friendly pick can cost several times more. Decide what matters most to you first.
• "China access ≥ 2 stars" is the hidden bar for China-facing sites — this ranking already filters out providers rated 0, but some 1-star China-access providers still make the list (great overseas reputation, but mainland access may drop packets). If your users are mainly in China, always check the CN column.
• Prefer providers with a refund window — the table flags a "Refund" column; with 7 / 14 / 30-day providers you can "start monthly, test for a week, and renew annually once speeds check out." For 2026 providers still offering no refund, find real user feedback in reviews / Trustpilot before you buy.
• Mind the ranking's timeliness — this ranking is regenerated at the start of each year; data is incrementally updated each month in between, but the ranking itself stays fixed for stable SEO indexing. For the live click-based ranking see /en/trending.
