The API is accessible at api.kite.trade and documented at kite.trade/docs/connect/. Kite Connect is structured as a REST API for transactional operations and a binary WebSocket endpoint for real-time streaming market data.

Kite Connect is used to build algorithmic trading systems, portfolio analytics platforms, strategy backtesting tools, brokerage white-label applications, and research dashboards. Zerodha charges a monthly subscription fee for Kite Connect access, distinct from the zero-commission brokerage model for retail clients trading manually through Kite Web or Kite Mobile. As of 2024, Kite Connect has been integrated by hundreds of third-party fintech applications and by a large community of individual developers building personal trading systems. The Kite Connect ecosystem article covers the developer community, official client libraries, and marketplace in detail.

Kite Demo (Zerodha paper trading environment)

Mon, 11 May 2026 00:00:00 +0000

Kite Demo is a simulated paper trading environment operated by Zerodha that replicates the interface and functionality of the Kite trading platform without executing orders on real exchanges or requiring a Zerodha account. It is accessible at kite.zerodha.com/demo and is intended to allow prospective clients to explore the Kite interface, practise order placement, and familiarise themselves with the platform’s features before opening a live account.

Kite Demo presents a pre-populated watchlist with selected NSE-listed instruments and displays real-time (or slightly delayed) market data from the live exchange. When a user places an order in Kite Demo, the order is simulated within the demo environment and does not reach NSE’s or BSE’s order matching systems. Positions and P&L in Kite Demo are notional and carry no financial obligation.

It supports trading across NSE and BSE equities, equity futures and options, currency derivatives, and MCX commodity derivatives, matching the segment coverage of Kite Web.

Mon, 11 May 2026 00:00:00 +0000

Kite nudges is a behavioural intervention framework integrated into Zerodha’s Kite trading platform, active on both Kite Web and the Kite Mobile app. The framework surfaces contextual alerts and warnings during a client’s order placement flow when the system detects a pattern associated with statistically adverse trading outcomes. The design draws on behavioural economics principles to prompt traders to reconsider specific order characteristics without blocking order submission.

The nudges framework is described in detail in Zerodha’s Z-Connect blog posts and forms part of SEBI’s stated preference for brokers to implement investor protection measures beyond mandatory compliance requirements.

The platform is accessible within the Kite interface via the Option Chain link and as a standalone web application at sensibull.com.

The platform targets the segment of active traders who wish to systematise their trading rules without writing code in Python, Java, or other programming languages. By abstracting strategy logic into a graphical condition interface and connecting live execution to Kite Connect, Streak provides a no-code path to algorithmic trading within the regulatory constraints applicable to Indian retail brokerage.

It serves as the administrative complement to Kite, which is Zerodha’s order-execution interface.

Console aggregates data across all segments in which a client trades, including NSE and BSE equities, equity futures and options, currency derivatives, commodity derivatives (MCX and NCDEX), and direct mutual fund units held through Zerodha Coin. The portal generates documents required for Indian income tax filing: the tradewise profit-and-loss report, the capital gains report covering both short-term and long-term gains, the F&O turnover statement for tax audit determination, and the full contract note archive going back to account opening.

Zerodha Pi (legacy desktop trading terminal)

Mon, 11 May 2026 00:00:00 +0000

Zerodha Pi (often written as Pi) was a proprietary Windows desktop trading terminal developed and operated by Zerodha from approximately 2014. Pi was designed as an advanced trading platform for active traders who required sophisticated charting, strategy scripting, and back-testing capabilities not available in the NEST-based Zerodha Trader terminal that preceded it. Pi was retired and replaced by the browser-based Kite platform after Kite became feature-mature between 2016 and 2018.

Pi was notable in the Indian discount brokerage market as an attempt to offer features comparable to full-service broker desktop terminals (which licensed platforms such as ODIN from Financial Technologies India or advanced charting add-ons) to discount brokerage clients without additional charge.

Mon, 11 May 2026 00:00:00 +0000

Zerodha Sentinel is a price and market condition alert platform operated by Zerodha, accessible at sentinel.zerodha.com. Sentinel allows traders and investors to set alert conditions on NSE and BSE listed instruments (equities, indices, futures, and options) and receive notifications via push notification to the Kite Mobile app, email, or SMS when the specified conditions are met. Sentinel operates independently of exchange order entry; it does not place orders on the exchange but only notifies the user, leaving the order decision and execution to the user.

Zerodha Trader and NEST (legacy trading terminal)

Mon, 11 May 2026 00:00:00 +0000

Zerodha Trader was the primary order-entry interface for Zerodha clients from 2010 until it was progressively replaced by the Pi desktop terminal and then the browser-based Kite platform over the period 2014 to 2018.
