Analytics

Dev can collect anonymous analytics to help improve dev's ability to work with LLMs, edit code and complete user requests.

Opt-in, anonymous, no personal info

Analytics are only collected if you agree and opt-in. Dev respects your privacy and never collects your code, chat messages, keys or personal info.

Dev collects information on:

• which LLMs are used and with how many tokens,
• which of dev's edit formats are used,
• how often features and commands are used,
• information about exceptions and errors,
• etc

These analytics are associated with an anonymous, randomly generated UUID4 user identifier.

This information helps improve dev by identifying which models, edit formats, features and commands are most used. It also helps uncover bugs that users are experiencing, so that they can be fixed in upcoming releases.

Disabling analytics

You can opt out of analytics forever by running this command one time:

dev --analytics-disable

Enabling analytics

The --[no-]analytics switch controls whether analytics are enabled for the current session:

• --analytics will turn on analytics for the current session. This will not have any effect if you have permanently disabled analytics with --analytics-disable. If this is the first time you have enabled analytics, dev will confirm you wish to opt-in to analytics.
• --no-analytics will turn off analytics for the current session.
• By default, if you don't provide --analytics or --no-analytics, dev will enable analytics for a random subset of users. This will never happen if you have permanently disabled analytics with --analytics-disable. Randomly selected users will be asked if they wish to opt-in to analytics.

Opting in

The first time analytics are enabled, you will need to agree to opt-in.

dev --analytics

Dev respects your privacy and never collects your code, prompts, chats, keys or any personal
