Our verdict on Bilgu Bulk Domain Availability Checker

Bilgu Bulk Domain Availability Checker is a free web tool for checking domain availability in bulk. It suits domain investors, startup founders, marketing agencies, SEO teams, brand-protection teams and e-commerce businesses that need to review a prepared list rather than generate domain ideas. Users can paste newline-separated or comma-separated domains, and the checker handles up to 500 domains per run without an account or sign-up.

The published offering centers on a straightforward free workflow. Live DNS, WHOIS and RDAP checks provide availability results, while automatic duplicate removal keeps repeated entries from cluttering the review. Results are separated into available and taken domains, with select-all and deselect-all controls for managing the list. CSV export includes domain, status and message columns, making the output suitable for follow-up work outside the browser.

Its platform fit is focused rather than broad. The tool runs on the web and connects with Spaceship for bulk checkout, allowing selected domains to move toward registration through that service. It does not provide domain generation, domain variations or API access, so it is not designed for automated pipelines or wider naming research. Choose Bilgu when the priority is a simple, free availability check for an existing list; choose another tool when discovery, programmatic access or broader domain research is central to the workflow.
