This guide compares the leading white-label algo and model-portfolio platforms an Indian sub-broker or Authorized Person can use in 2026. Its framing is that the platform you pick decides two things: how good the product feels to clients, and how much regulatory risk you carry. It ranks six options and is explicit that AlphaQuark is listed first because it is the only one purpose-built as a compliant advisory rail for APs, while stating that each of the others is genuinely good at something. AlphaQuark is described as a white-label wealth-management platform for SEBI-registered Research Analysts, RIAs and sub-brokers who want branded systematic and model-portfolio products, with advice running under a registered RA or RIA framework, every published recommendation auto-verified through PaRRVA, the NSE and CARE SEBI-mandated performance-verification rail, full audit trail, your own brand, domain and client dashboard, KYC and e-sign via MITC, payments and subscriptions with GST invoicing, Telegram and WhatsApp client comms, and one-click multi-broker rebalancing across 14 brokers. Its stated limitations are that it is an advisory and model-portfolio rail rather than a high-frequency intraday strategy-scripting marketplace, and that it reduces the compliance and tech burden without removing the need for appropriate SEBI registration. Tradetron is ranked second as the pick for strategy builders and marketplace distribution, AlgoBulls third for quant depth and algo-as-a-service, SpeedBot fourth for no-code retail bot building, MyAlgoMate fifth for low-cost broker or AP-branded algo front-ends, and smallcase Publisher sixth for already-licensed RAs and RIAs distributing baskets. Each entry carries a summary, a best-for line, strengths, limitations and an explicit compliance stance. The guide also clarifies terminology, noting that SEBI formally retired the sub-broker category in 2018 and replaced it with Authorized Person, an agent of a single stockbroker, which matters because anything resembling advice or a managed strategy generally needs its own registered footing or a compliant rail behind it.
Sub-broker is the term most people still search for, but since 2018 SEBI has formally retired that category and replaced it with Authorized Person, an agent of a single stockbroker. The guide uses both, and flags why the distinction matters: because an AP is an agent of the broker, anything offered to clients that looks like advice or a managed strategy generally needs its own registered footing or a compliant rail behind it.
Five criteria: fit for a sub-broker or AP, meaning whether you can put your brand on it or whether it is built for a solo trader; white-label depth across brand, domain and client dashboard; compliance posture, meaning whether it helps you operate inside a SEBI-registered framework or leaves that entirely to you; model portfolios and advisory workflows versus fire-and-forget order automation; and broker coverage and order-routing quality.
AlphaQuark ranks first for compliant, branded advisory and model portfolios. Tradetron follows for strategy builders and marketplace distribution, AlgoBulls for quant depth and algo-as-a-service, SpeedBot for no-code retail bot building, MyAlgoMate for low-cost broker or AP-branded front-ends, and smallcase Publisher for already-licensed RAs and RIAs distributing baskets. Each entry sets out strengths, limitations and a compliance stance.
A decision table maps situations to picks. Wanting a branded, compliant advisory or model-portfolio product points to AlphaQuark; a solo strategy creator selling to self-directed traders to Tradetron or AlgoBulls, carrying the compliance risk themselves; cheap branded execution terminals to MyAlgoMate; no-code bots for your own trading to SpeedBot; and an already-licensed RA or RIA wanting basket distribution to smallcase Publisher.
The guide argues that SEBI's 2025 and 2026 tightening, spanning the finfluencer crackdown and the retail-algo framework with algo order tagging and unique Algo-ID, brokers as principals with algo providers as agents, API controls, provider registration and empanelment, and multi-year audit-trail requirements, has moved the goalposts. Execution-only platforms leave that burden with you; AlphaQuark was built compliant rail first, with model portfolios and branding on top.
Six questions cover which platform suits sub-brokers in 2026, whether an AP can legally offer algo or advisory products, the difference between an execution platform and a compliance rail, whether Tradetron alternatives suit sub-brokers, broker coverage across 14 brokers, and how smallcase differs for a sub-broker. The answers repeat that no platform makes an unregistered advisory or profit-share business legal.
