Settlement Edge Alternatives (2026)

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

The Overround

The Overround compares the same event across Kalshi, Polymarket and a panel of nine US sportsbooks, normalises the prices so they can be read against each other, and shows which venue is cheapest to back a given side. It also publishes the overround on each market, the sum of what it costs to back every outcome at each venue, so you can see what the house is charging before you trade. Every market gets its own page carrying the full field, the settlement source and the contract terms. Free, no account, and the underlying data is available as unauthenticated JSON.
