How Marketlens differs from pmdata.dev
pmdata.dev is the closest philosophical neighbour: tick by tick book updates and a full archive on its paid plan. The difference is coverage dates and tooling. pmdata.dev covers crypto up/down markets since February 2026 and all Polymarket markets since May 2026; Marketlens covers every recurring Polymarket market type, including sports, esports, weather, equities earnings, and structured products, with the same change level capture, in an archive that starts in March 2026.
On tooling, pmdata.dev hands you Parquet files for hftbacktest. Marketlens serves both workflows: a query API and SDK for interactive research, bulk Parquet exports for offline pipelines, and its own backtesting engine with queue priority, latency, and fee modelling, so you do not need to assemble a separate harness unless you want to.
Which should you pick?

FAQ
Common questions
What is the best pmdata.dev alternative?
Marketlens, if you need books outside crypto up/down from before May 2026 or an integrated backtesting engine. It records millisecond L2 books for every recurring Polymarket market type, serves them through an API, SDK, and Parquet exports, and includes execution realistic backtesting. The free tier covers markets open in the last 7 days with 2M data rows one time; Pro starts at $39/mo versus pmdata.dev from $49/mo.
Does pmdata.dev cover sports or weather markets?
Yes, since May 2026, when its coverage expanded from crypto up/down to all Polymarket markets. Marketlens also records per game sports books, daily weather buckets, equities earnings markets, indices, commodities, and macro markets.
Can I use Marketlens data with hftbacktest?
Marketlens Parquet exports contain full book snapshots, deltas, and trades per market, which you can transform into hftbacktest's input format. If you would rather skip the glue code, the built in backtester replays the same data tick by tick with queue priority, latency, slippage, and Polymarket fees.
