Quickwit — #2 Alternative to Splunk
Rust cloud-native search engine querying petabytes of logs directly on S3 object storage
Built on Tantivy in Rust, Quickwit decouples stateless indexing/search compute from S3/R2 object storage—delivering sub-second full-text log and trace search at roughly 1/10th the infrastructure cost of Splunk or Elasticsearch.
