Quantopian died in 2020.
The itch it scratched didn't.
Quantopian's shutdown scattered ~200k quants across forks and clouds — zipline-reloaded for compatibility, QuantConnect for infrastructure, Backtrader for stubbornness. EventTrader offers the missing piece most migrations lost: free always-on hosting for live strategies, with a real API.
Always-on strategy hosting
Cloned or configured bots run server-side around the clock — no VPS to rent, no notebook to babysit.
Browse the strategy bots →Free live deployment
Deploying a strategy against live markets costs nothing beyond the positions it takes. No per-node compute billing.
Deploy a strategy →API, SDK, MCP
Documented REST API with generous authenticated rate limits, an SDK, and an MCP server for AI-driven workflows.

- The platform shut down 3 November 2020; the community dispersed and the forums are gone
- zipline survives only as a community fork (zipline-reloaded) with manual data-bundle setup and no built-in live trading
- Successor platforms bill $200–400/mo all-in for serious use

What you'd actually be trading here
EventTrader is a prediction exchange: perpetual prediction markets on crypto, stocks and macro moves with no expiry, live central-limit order books, event markets on real-world outcomes, and a marketplace of trading bots you can clone instead of coding. Position risk is capped at what you put in — no liquidation engine, no margin calls. Server-side alerts and free webhook auto-execution come with every account.
- Free means free. No card required. Nothing auto-converts into a paid plan.
- We are not a backtesting IDE. EventTrader is a prediction exchange where strategies run live — bring your research, deploy the result.
- No predictions sold. Markets are markets; we make no performance claims.
- Leave in one click. Withdraw on-chain any time, with a tx hash you can verify.
