# Happy vs Codex Relay

The clearest difference is rating: Happy at 4.9 against Codex Relay's 4.2. Happy also leads on ratings volume (991 vs 54) and update cadence (weekly vs fortnightly). Codex Relay's advantage is in-app purchases (none vs 1). On price, review sentiment, ads and chart position there is nothing between them.
