Free Polymarket bots & tools
Everything in the catalog that you can start using without paying, sorted by what "free" actually means here — because an open-source bot you self-host, a free tier with a Pro plan behind it and a terminal that takes 1% of every trade are three different deals.
Completely free
32No price, no paid tier named, or open-source under a free licence. The author may still charge for something later — check the pricing note on each listing.
Virae AI
Platforms & ToolsAI trading terminal for Polymarket, in private beta: market discovery with live trending topics and order-book prices, a whale leaderboard ranking tracked wallets by PnL, volume, win rate and Sharpe with one-click copy tasks, and seven trading Agents across four strategy types — end-of-round BTC/ETH price-distance, pre-market maker ladders, weather-model probabilities and Musk tweet counts. Agents watch every eligible round and only place orders when sizing, liquidity and entry rules all pass; each ships with recorded paper performance clearly labelled as simulation, and the strategy-evaluation core is open source on GitHub. Turnkey-backed non-custodial wallets, web app plus Telegram bots, and a separate Solana memecoin terminal.
Ratio
Copy TradingSocial prediction-market app for iOS and Android built around copying Polymarket traders. Browse markets, follow forecasters from a global leaderboard, mirror their positions with your own sizing, and read the reasoning they post next to each trade. Wallet tracking, alerts and portfolio analytics sit alongside the feed. The wallet is self-custodial — you hold the keys and can export them — and every trade settles on Polymarket itself, not on Ratio's infrastructure.
Infinity
A full trading terminal inside Telegram, covering two venues at once: Polymarket prediction markets on the live CLOB order book, and Hyperliquid perps and spot — plus copy-trading on top. There is no baked-in strategy; Infinity is the execution layer, so you decide and it fills. Each account gets its own dedicated wallet per venue, AES-256-GCM encrypted at rest and exportable at any time. Written in Rust, translated into 8 languages, and running on mainnet with on-chain fills anyone can verify.
Almanac
Platforms & ToolsPrediction market that pays for being right early.

What "free" means on Polymarket
Free comes in three shapes here, and the groups above keep them apart. Fully free tools — open-source bots you run yourself and web apps that don't charge — come first. Then the freemium tier: a usable free plan with the features that matter behind a subscription. Last, tools that cost nothing up front but take a percentage of every trade or of profits; those are free to try and anything but free once you trade size.
Most free entries are analytics, screeners and copy-trading terminals rather than automated bots: the hosting is the product and the business model is the paid tier or the per-trade fee. Fully automated bots that are free tend to be open-source repositories — which means you supply the server, the API keys and the operations, and nobody is on call when it breaks.
Listings whose pricing isn't published ("see site", "waitlist", "custom") are deliberately not counted as free. We only file a tool under free when the author says so.
How to pick a free tool
Ask what the free plan actually does. Many free tiers show data but gate execution, alerts or the strategies you came for. Check the feature list on each card against what you would actually use, then read the pricing note on the detail page for the catch.
Per-trade fees add up faster than a subscription. A 1% fee on every fill is $10 per $1,000 traded each way; trade actively and a flat monthly plan can be the cheaper "free" option. Work out your monthly volume before you call anything free.
Free still costs you your keys. Only connect wallets and API keys to tools you have checked, prefer non-custodial setups, and with open-source bots read the code before you fund it — the point of having the source is that you can.
Frequently asked questions
- Are there completely free Polymarket bots?
- Yes — the open-source ones. They are published under free licences (MIT) and cost nothing to use, but they are free software rather than a free service: you host them, you supply the API keys, and you operate them. The "Completely free" group above lists them alongside free web tools.
- Is a free tier enough to actually trade?
- Sometimes. Free tiers on terminals and trackers usually cover research — screening, wallet tracking, alerts — and gate execution, automation or the higher-value signals. Read the pricing note on each listing; it says what the free plan leaves out.
- What is the difference between free and open-source?
- A free tool costs nothing to use; an open-source bot also lets you read and change the code, and keep running it if the author disappears. Every open-source bot here is free, but most free tools are not open-source. They have their own page: open-source Polymarket bots.
- Do free bots publish performance?
- Rarely. Most free tools are research products without a trading record to publish, and most free bots are open-source repositories that ship no live results. Every listing shows the author's published 30-day ROI or N/A; POLBOTS does not verify performance either way.
- Why isn't a tool I know is free on this page?
- Because its listing doesn't say so. Tools that publish no pricing ("see site", "waitlist") are not filed as free, and tools with a per-trade fee are in their own group. If a listing is out of date, tell us and it gets fixed.
