Our verdict
A usable project with some maintenance caveats. This assessment is derived from GitHub's own repository metrics on 2026-10-19, not from hands-on testing.
XERJ is the new way for AI to search data. Its autoindex capability activates agents to know your data without the token waste of grep (1974 tool). One command indexes code, docs, logs and PDFs for search, RAG, security audits and agent memory, using 40x fewer tokens than grep. It’s durable and can replace ElasticSearch saving you x10 infra costs. The project is written primarily in Rust, released under Apache-2.0, and has 8,702 stars and 466 forks on GitHub. 55 contributors have committed to it, and the most recent push was 2026-10-19. The latest tagged release is pack-foodon-cd735402 (2026-10-19). Figures come from the GitHub API on 2026-10-19 and are refreshed daily; the score below weighs adoption, maintenance, release discipline, contributor breadth, licence clarity and issue hygiene.

Pros and cons
Pros
Pricing
- Free tierYes
- LicenceApache-2.0
- Self-hostYes, source is public
- Public price listNot published
XERJ does not publish a web price list. For consumer apps that usually means pricing appears inside the product; for enterprise tools it means talking to sales. Why we do this
