What is Groonga?

Groonga is putting a full-text search engine into WebAssembly and the browser.

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

What is Sonic?

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

Groonga vs Sonic: editorial side-by-side

G
Groonga
DEVOPS
5.0

Groonga is putting a full-text search engine into WebAssembly and the browser.

◆ Current state

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

◆ Where it's heading

The WebAssembly work is moving piece by piece from the core command to options and plugins, which points toward a usable in-browser search engine. Every WASI item is still marked experimental and not stable.

◆ Prediction

Expect more WASI coverage in the next 16.1.x releases, with the experimental label likely to stay for now.

2.5

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

◆ Current state

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

◆ Where it's heading

The 1.x line is moving fast on ingest performance and correctness for high-scale and non-English users, at the cost of some unstable releases. Experimental APIs are being tested in production before they reach official builds.

◆ Prediction

Expect the experimental high-scale PUSH features to graduate out of the feature flag in a later 1.x; when is unclear.
