20 free GitHub repositories for trading on Polymarket

The top leaderboard wallets on Polymarket are not geniuses with quick fingers or superhuman intelligence.

They are usually well-prepared traders who use a lot of extra tools to make their trading and decision making easier.

There are many paid tools where you can get different trading features for around $50 per month. But why do I need to pay for them if all these tools are already available for free on the web...

So I spent a few days finding and testing different tools to show you 20 Free Polymarket Trading Tools on GitHub for any trading situation.

I divided all the repos into categories so it is easier to navigate and find exactly what is useful and interesting for you.

> most of these tools can also be used for trading on other prediction market platforms.

The main feature of this bot - it can track its own results, learn and improve its own strategy over time. GitHub: https://github.com/nicolastinkl/hermes_weatherbot
4. GFS based weather trading bot. It uses 31 different forecast scenarios from the Global Forecast System for a specific city and day to estimate the most accurate temperature outcome.

🔴Security Warning

All of these repositories were personally tested by me, but please be careful - there are still a lot of scam repos on GitHub.

Some of them may contain built-in drainers that can steal your wallet private key and withdraw all your funds.

Or may include malicious code that can give an attacker access to your pc and all your local files once you run the code.

So if you are not 100% sure that this repo is safe, run it only in a virtual machine first and create a separate Polymarket account just for testing.

This way, you can reduce the risks and avoid stealing your main wallet, funds and personal files.
