DevKit is the developer toolbox you already keep open in a browser tab, rebuilt as a native app for iPhone, iPad and Mac — and it works with the radio off. Paste something and DevKit works out what it is. A JSON Web Token, a certificate, a cron line, a CIDR block, a colour, a hex digest: it recognises the shape and offers the right tool.

The clearest difference is in-app purchases: Codex Relay at none against DevKit's 3. Codex Relay also leads on chart position (#34 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
