Free Bot Options
Two ways to run a Polymarket bot for free: PredictEngine free tier (no-code, managed) and open-source Python (DIY, self-hosted). Both work with real Polymarket markets.
PredictEngine free accounts get 1,500 credits at signup plus 250 daily credits. This is enough to run bots, use the AI builder, and trade live. No credit card required.
Free Bot with PredictEngine
Sign up for free at PredictEngine. Open the AI Builder and describe your strategy. The AI creates a fully configured bot. Run it in simulation mode for free, or fund your wallet with USDC for live trading.
The free tier includes: 1 active bot, simulation mode, AI strategy builder, whale alerts, and news feed. Upgrade to Pro ($19.99/month) for unlimited bots and advanced features.
Free Open-Source Python Bot
Polymarket's py-clob-client SDK is free and open-source. Build a custom bot with full control over strategy, execution, and data. The code is free; you pay only for hosting (~$5/month VPS).
For truly $0 cost, run the bot on your own computer during trading hours. You lose 24/7 uptime but pay nothing. This works for event-driven strategies that don't need constant monitoring.
Free Simulation Mode
PredictEngine's simulation mode lets you test any strategy with virtual money on real market data. This is the safest way to develop and validate strategies before risking capital.
Run multiple simulated bots side-by-side to compare strategies. Track simulated P&L and win rates. Switch winning strategies to live trading when you are ready.
