ZincSearch
activeby ZincSearch community (originally Zinc Labs, now OpenObserve) · since 2021 · also known as Zinc, Zinc Search
Lightweight single-binary full-text search engine in Go with Elasticsearch-compatible ingest.
Overview
ZincSearch is a small Go search engine built on the bluge indexing library, created by the team that later built OpenObserve. It ships as one binary with an embedded web UI, accepts data through Elasticsearch-compatible bulk and index APIs, and needs a fraction of Elasticsearch's memory. The original company now steers log users to OpenObserve, and ZincSearch has become community-maintained; after a quiet 2024-25 it resumed releases in September 2026 with 0.4.11 and a 1.0 beta. Good for small app search or replacing a tiny Elasticsearch node, not for serious scale.
Strengths & trade-offs
Strengths
- +Single binary with built-in web UI
- +Very low memory use compared with Elasticsearch
- +Elasticsearch-compatible bulk ingestion makes migration of small workloads easy
- +Schemaless documents with no upfront mapping
Trade-offs
- −No clustering or replication
- −Small community-driven maintainer base after the company moved on
- −No vector search
- −Query DSL compatibility with Elasticsearch is partial
Great for
- +Small application search
- +Lightweight replacement for a single Elasticsearch node
- +Developer and test environments
Think twice for
- −Production log analytics (use OpenObserve or Quickwit)
- −High availability requirements
- −Semantic or vector search

Does ZincSearch support ACID transactions?
No. ZincSearch does not provide ACID transactions; its consistency model is eventual.
Does ZincSearch scale horizontally?
ZincSearch does not scale horizontally; it runs on a single node, so you scale it up rather than out. It is comfortable at small scale (≤ 100 GB).
How can I run ZincSearch?
You can self-host it.
What is ZincSearch best for?
ZincSearch is a strong fit for small application search; lightweight replacement for a single Elasticsearch node; and developer and test environments. Think twice for production log analytics (use OpenObserve or Quickwit).
What are the best alternatives to ZincSearch?
Common alternatives to ZincSearch include Meilisearch, Typesense, OpenObserve, Elasticsearch and Sonic. The right choice depends on your workload, scale and hosting; WhichDB's smart match ranks them against your requirements.
