What is HaasOnline?
HaasOnline is a non-custodial cryptocurrency trading automation platform that enables users to develop, backtest, and run algorithmic trading strategies across centralized spot and derivatives venues. Rather than holding deposits, the system executes trades directly on connected third-party exchanges through user-generated API keys.
Company background and ownership
HaasOnline was founded in 2014 by Stephan de Haas and operated through Haasonline Software BV, based in Rotterdam, Netherlands. In November 2025, Haasonline Software BV announced an acquisition agreement transferring the platform to a new ownership group with historical ties to its development, restarting active product sales in January 2026.
Platform mechanics and architecture
Traders run bots either through TradeServer Cloud, a fully hosted setup, or through self-hosted on-premise TradeServer software deployed on their own hardware. The software links to 19 supported exchanges across 34 integrations, including Binance, Bybit, and Kraken. Users can assemble strategies using pre-built templates for dollar-cost averaging (DCA), grid trading, scalping, arbitrage, and market making. For custom logic, the platform provides a drag-and-drop visual builder alongside HaasScript, a proprietary trading language. Strategy validation is handled through historical backtesting and paper trading on live order books. An MCP integration lets users connect language models like Claude or ChatGPT to inspect logs and build HaasScript strategies under code-enforced boundaries that prevent order placement or fund movement.
Pricing and account access
HaasOnline charges a fixed subscription fee, with plan tiers such as Standard pricing around $29.99 per month when billed annually in Bitcoin. The software charges 0% per-trade fees and zero management fees, leaving users responsible only for standard exchange trading fees. Subscriptions include a 7-day free trial, and sign-ups require no direct identity verification because assets stay on external exchanges.
Track record and operational risks
By October 2026, the platform had processed over $6.4B in total trading volume across 82M executed orders and 13.8M backtests. In October 2026, HaasOnline expanded developer access by releasing a public REST API with 28 endpoints covering scoped keys and IP allowlists. The platform has recorded no security breaches. However, automated trading carries market execution risks, including slippage, liquidation on leveraged positions, and strategy underperformance during extreme volatility. Users also face counterparty exposure to connected exchanges and must securely manage their own API key permissions.

Our review
3.8/5
Good
HaasOnline provides powerful scripting and non-custodial exchange automation across cloud or self-hosted setups, but its steep learning curve and lack of regulatory licensing require technical discipline.
Founded in 2014 by Stephan de Haas in the Netherlands, HaasOnline is an established trading automation platform operating through Haasonline Software BV. In late 2025, Haasonline Software BV agreed to an acquisition by a new ownership group that assumed platform and support operations. The service operates non-custodially: users connect exchange accounts through API keys, leaving all capital and withdrawals strictly at the trading venue. Since launch, the platform has processed over 82 million orders, 13.8 million backtests, and $6.4B in cumulative trading volume across 19 supported exchanges and 34 venue integrations, with no reported security breaches.
HaasOnline offers architectural choices through managed TradeServer Cloud environments or self-hosted on-premise TradeServer instances. Custom logic runs on HaasScript, a domain-specific language paired with visual drag-and-drop workflow builders alongside code editors. Available strategies span spot and derivative markets, supporting grid setups, dollar-cost averaging, arbitrage, and custom index rebalancing. Recent platform updates added a Model Context Protocol integration that lets AI models analyze logs and draft backtests without order-routing or withdrawal permissions, as well as a 28-endpoint REST API launched in October 2026.
The platform operates on a fixed subscription model with zero trade fees and zero management surcharges, alongside a 7-day trial. However, traders face several notable trade-offs:
- Complexity remains substantial. Mastering HaasScript requires far more technical effort than typical retail copy-trading apps.
- HaasOnline holds no formal financial licenses, meaning regulatory protections depend entirely on each connected exchange.
- Traders remain fully exposed to execution errors and venue API rate limits.
HaasOnline suits algorithmic traders and quant developers who require customizable strategy logic without third-party fund custody. Casual traders seeking automated copy trading or simple mobile execution should consider alternative plug-and-play retail terminals.
