What is free—and what is not?
The standard GitHub and Reddit tools require an Opsis account but do not spend search credits. GitHub deep scans and optional AI analysis are separate, credit-based actions. Instagram offers an anonymous limited preview, with additional detail available after signing in.
These focused tools are separate from Opsis’s multi-source email and username searches, which require a subscription. Opening a guide or visiting a tool page does not run a search.
Create an account to use account-required tools, or compare subscriptions for multi-source searches.
Choose the tool that matches your starting point
Use GitHub for a developer’s known handle and public repository context. Use Reddit for a known Reddit username and public community activity. Use Instagram to check a known Instagram handle and available profile information.
A username on one platform does not establish that the same handle elsewhere belongs to the same person. These tools do not promise access to private posts, private messages, or every field on a profile.
Starting with an email instead? Read the reverse email lookup guide. Before interpreting a match, see how to evaluate results.
