What ZincSearch Actually Does

Quick Start

3 Practical Use Cases

1. Application Log Search

2. Product Search for E-Commerce

3. Full-Text Search for Documentation Sites

Why This Matters Your side project needs search. You looked at Elasticsearch — minimum 2GB RAM, Java dependency, complex cluster setup. You looked at Algolia — $1/1000 records/month adds up fast. ZincSearch is a single Go binary that gives you Elasticsearch-compatible search on 50MB of RAM. ZincSearch (now called OpenObserve for the observability use case) is an open-source search engine written in Go. It provides full-text search with an Elasticsearch-compatible API, a built-in web UI for data exploration, and S3-compatible storage for cost-effective data retention. The design philosophy: make search accessible to everyone, not just teams with DevOps engineers. One binary, one command to start, built-in UI for exploring data. No JVM, no cluster coordination, no YAML configuration files. ZincSearch supports Elasticsearch-compatible ingest and search APIs, so existing tools and libraries work with minimal changes. Open-source under Apache 2.0. Search (Elasticsearch-compatible): Then search logs via the built-in UI at http://localhost:4080 or API. Search shouldn't require a dedicated infrastructure team. ZincSearch brings full-text search to the 99% of projects that don't need Elasticsearch's scale but do need its query capabilities. One binary, 50MB RAM, Elasticsearch-compatible API, built-in UI. That's the entire ops story. Need custom data extraction or web scraping solutions? I build production-grade scrapers and data pipelines.
