If your top priority is **uptime and reliability during market hours**, the current consensus in 2026 puts slightly ahead of most retail brokers, though no Indian broker has perfect uptime. Recent outage reports and trader feedback consistently rate its infrastructure as among the most stable. ### Reliability-focused ranking (2026) | App | Reliability / Uptime Reputation | Notes | |------|------|------| | Zerodha | ★★★★★ | Best overall stability reputation; Kite remains the benchmark platform. | | Dhan | ★★★★½ | Frequently praised by active traders for execution stability and TradingView integration. | | HDFC Sky | ★★★★½ | Bank-backed infrastructure; fewer complaints about opening-hour outages. | | Groww | ★★★★☆ | Excellent for beginners, but has had more user-reported peak-hour issues than Zerodha. | | Upstox | ★★★★☆ | Good feature set, though some NSE-recorded technical glitches were reported in FY 2026. | | Angel One | ★★★★☆ | Strong tools and research, but not generally viewed as the most stable for heavy traders. | ### For different investor types - **Long-term investing + SIPs:** or - **Active stock/F&O trading:** or - **Maximum reliability over fancy UI:** or - **Algo/API trading:** remains the most mature ecosystem despite occasional latency spikes. ### Important context Many of the largest outages in 2025–26 were caused by external infrastructure providers (for example the Cloudflare outage) and affected multiple brokers simultaneously, including Zerodha, Groww, Upstox, and Angel One. So "uptime" isn't only about the broker's own systems. ### Bottom line For someone opening a fresh account in India in 2026 and prioritizing **uptime first**, **Zerodha** is still the safest default choice. If you trade heavily in options and want an alternative, **Dhan** is probably the strongest challenger. For pure investing and SIPs, **Groww** remains the easiest app to use but is not generally considered the uptime leader.
