# Codex Relay vs HTML Runner

The clearest difference is rating: HTML Runner at 4.8 against Codex Relay's 4.2. HTML Runner also leads on review sentiment (100% vs 71%). Codex Relay's advantage is in-app purchases (none vs 3) and ratings volume (54 vs 5). On price, update cadence, ads and chart position there is nothing between them.

Both are free to download. HTML Runner sells 3 in-app purchases, starting at $0.99 per month. Codex Relay asks for nothing beyond the download.

HTML Runner holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Codex Relay has 54 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 71% of Codex Relay's written reviews are positive against 100% of HTML Runner's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
