# JavaScript Studio vs CodeInsight

The clearest difference is rating: JavaScript Studio at 4.9 against CodeInsight's 4.0. JavaScript Studio also leads on in-app purchases (none vs 1) and ratings volume (8 vs 1). CodeInsight's advantage is update cadence (every 2 weeks vs every 10 months). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. CodeInsight sells 1 one-off in-app purchase. JavaScript Studio asks for nothing beyond the download.

JavaScript Studio holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: JavaScript Studio has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

JavaScript Studio ships an update every 10 months, CodeInsight every 2 weeks. The most recent releases landed on June 1, 2026 and September 16, 2026 respectively.
