Hex37 vs the testnets
The Binance Testnet alternative that doesn't reset or disappear
The Binance Futures testnet was built for developers testing API code, not for traders practising. It lives on a separate account, its liquidity does not match live markets, and Binance has been winding down general testnet access. Hex37 is a free crypto futures simulator built for practice: $10,000 in virtual funds, live prices, real funding and liquidation mechanics, and a trade journal that never resets.

Why practising traders switch
It does not reset
Exchange demo accounts are throwaway by design. Bybit's demo clears after a stretch of inactivity, and the Binance testnet is being phased out. Your Hex37 history is permanent, so the trade journal can show you months of patterns instead of starting over every time you take a break.
It is built for practice, not API QA
The testnet exists so developers can hammer the API without real money. That is why it has thin liquidity and a separate login. Hex37 simulates slippage, partial fills, and funding on live prices specifically so the practice transfers to a real account.
It journals every trade for you
Every fill is logged automatically with entry, exit, R-multiple, and notes, so you can see your real win rate and where you actually lose money. No CSV exports, no separate journaling app.
It is not locked to one exchange
You are not learning a single venue's quirks. Practise across major assets, then carry the skill to whatever exchange you actually trade on.
Frequently asked questions
- What is a good free alternative to the Binance Testnet?
- Hex37 is a free crypto futures simulator built for practice rather than exchange QA. You get $10,000 in virtual funds, live market prices, and a real matching engine that simulates funding, liquidation, and slippage, with a built-in trade journal. There is no separate testnet domain to register on and no faucet to claim test tokens.
- Why are people looking for a Binance Testnet replacement?
- The Binance Futures testnet is built for developers testing API integrations, not for traders practising. It uses a separate account and domain, its order-book liquidity does not match live markets, and Binance has signalled it is winding down general website testnet access. Traders who just want to practise futures risk-free often want something more stable and purpose-built.
- Does Hex37 simulate funding and liquidation like a real perp exchange?
- Yes. Hex37 runs a tick-based matching engine with isolated and cross margin, maintenance-margin tiers, liquidation, auto-deleveraging, and perpetual funding payments, plus simulated slippage and partial fills. The goal is for a paper position to behave the way a live one would, so the practice transfers.
- Does my practice account reset or expire?
- No. Your Hex37 account and its history are permanent. Some exchange demo accounts (for example Bybit's) clear after a period of inactivity; here your trade journal and stats stick around so you can review months of practice.
- Do I need an exchange account or KYC?
- No exchange account and no KYC. You sign up with an email and start immediately. Nothing here is real money, securities, or commodities; it is an educational sandbox on live market prices.
- Can I practise leverage and futures, not just spot?
- Yes. Hex37 supports spot and perpetual futures with leverage, limit and market orders, stop loss / take profit brackets, and reduce-only / post-only flags. There are free calculators for liquidation, leverage, funding cost, and position size, each of which can hand a prefilled setup straight into the simulator.
