Free browser searches: decide what you need to save
FreeUsername’s guide documents up to five handles at once, category filters, public profile details where available, and JSON or CSV exports. That makes it useful when you’re comparing a few old spellings or want a file to revisit later. It also distinguishes blocked checks from inconclusive responses; neither means a profile is absent.
The WhatsMyName repository is a dataset, not a browser interface. It directs users to whatsmyname.app, the free interface from OSINT Combine, and documents CSV/PDF export and category filters. FreeUsername is a separate, independent service, despite its former “WhatsMyName Apps” name.
IDCrawl is another free, no-signup option for finding social-profile candidates. If it gives you the public link you needed, open the page and review it. You don’t need to buy another search simply because a paid option exists.
Sherlock: keep searches in your terminal workflow
Sherlock fits readers who want to pass in several handles, select sites and save output for their own analysis. Its project documentation lists CSV and XLSX exports. The software is free and open source; installation, updates and result review are your work.
If you’ve never used a terminal, start by deciding whether you need that control. A free browser tool may answer a single lookup with less setup. Our ProfileTrace vs Sherlock comparison explains the installation and cost tradeoff in more detail.
Namechk: choose a name you can register
Namechk checks username and domain availability without an account or card. It answers a naming question: can I use this handle for a new project?
Confirm the result at the platform or registrar, then register the name there. The check doesn’t reserve it, and a domain registration can cost money even though the availability check is free.
ProfileTrace: try a prepaid browser search
ProfileTrace’s username search returns public-profile candidates, with evidence-saving guidance and official report or account-help links where available. Use it when you prefer reviewing links and next steps in a hosted results view. Reporting, recovery and the decision about a suspicious account remain yours.
Your first standard search is free, with no card required. You’ll need a confirmed account to access the results. Additional standard searches cost one credit each. The current packs are $2 for two credits, $5 for ten, $10 for 25 and $50 for 150, with no subscription or automatic renewal.
Social Catfish: start with the information you have
Social Catfish advertises username, image, email, phone, name and address searches. A photo or phone number calls for a different search from a handle lookup; confirm that the selected plan includes the search and access you want.
Its terms describe monthly and quarterly memberships. Check the selected plan’s full charge, renewal date and cancellation terms before paying.
