Gigablast was an American free and open-source web search engine and directory.

Founded in 2000, it was an independent engine and web crawler,[6] developed and maintained by Matt Wells, a former Infoseek employee and New Mexico Tech graduate.

The open-source search engine source code is written in the programming languages C and C++.

[9] The Gigablast engine provided search results to other companies at various times, including Ixquick,[10] Clusty,[11] Zuula, Snap,[12] Blingo, and Internet Archive.

[18] A feature called Gigabits provided relevant information in addition to what the user was searching for.
