# ReasonML vs Lua IDE

The clearest difference is rating: ReasonML at 5.0 against Lua IDE's 3.4. ReasonML also leads on review sentiment (100% vs 59%) and update cadence (every 2 days vs every 7 months). Lua IDE's advantage is ratings volume (22 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
