Rainbow Alternatives (2026)

The Aggregation Layer for Prediction Markets

Racinglines

We are early stage but plan to launch an alpha version this week. (This means web abb feature-complete, `racinglines` on pypi, MCP tool working.) All are currently free/ open-source at least thru end of this year. We are exploring pricing for next year but will always offer some free tier. I am looking for feedback right now on how this platform can help me/ what I might need to improve/ change to fulfill selection criteria. Thanks. gh: github.com/lalligagger/racinglines-public

Sports trading terminal for Polymarket. OddsFantasy prices every Polymarket sports market against sharp sportsbook lines (Pinnacle and others) in real time, so you see where Polymarket is mispriced before you trade.

Free trading terminal; paid plans add automation.

Whalidate

Copy trading for Polymarket. Whalidate scores whale wallets on how they made their money (return, settled trades, worst drawdown and how much of the profit came from one trade) and copies only the new trades that pass your rules: entry price band, slippage cap, market categories and loss limits. Every strategy runs free on paper first; live trading is a paid plan from $49/month with no per-trade fee.
