TinySearch is a lightweight, fast, full-text search engine. It is designed for static websites.

TinySearch is written in Rust, and then compiled to WebAssembly to run in the browser.
It can be used together with static site generators such as Jekyll, Hugo, zola, Cobalt, or Pelican.


How it works

tinysearch is a Rust/WASM port of the Python code from the article "Writing a full-text search engine using Bloom filters". It can be seen as an alternative to lunr.js and elasticlunr, which are quite heavy for smaller websites and require a lot of JavaScript.

The idea of tinysearch is to generate a small, self-contained WASM module from a list of articles on your website and run it directly on the frontend inside browsers.



  • Only searches for entire words. There are no search suggestions (yet).
  • Since we bundle all search indices for all articles into one static binary, we recommend to only use it for small- to medium-size websites. Expect around 4kB (non-compressed) per article.


wasm-pack is required to build the WASM module. Install it with

cargo install wasm-pack

To optimize the JavaScript output, you'll also need terser:

npm install terser -g

If you want to make the WebAssembly as small as possible, we recommend to install binaryen as well. On macOS you can install it with homebrew:

brew install binaryen

Alternatively, you can download the binary from the release page or use your OS package manager.

After that, you can install tinysearch itself:

cargo install tinysearch


As an input, we require a JSON file, which contains the content to index. Check out this example file.

tinysearch fixtures/index.json

ℹ️ You can take a look at the code examples for different static site generators here.
ℹ️ The body field in the JSON document is optional and can be skipped to just index post titles.

This will create a WASM module and the JavaScript glue code to integrate it into your homepage. You can open the demo.html from any webserver to see the result.

For example, Python has a built-in webserver for testing:

python3 -m http.server 

then browse to to see the result.

For advanced usage options, try

tinysearch --help

Please check what's required to host WebAssembly in production -- you will need to explicitly set mime gzip types.


If a full Rust setup, you can also use our nightly-built Docker images.


Available buid args:


docker run -v $PWD:/tmp tinysearch/cli index.json

Custom repo/branch build

docker build --build-arg WASM_BRANCH=master --build-arg TINY_MAGIC=64 -t tinysearch/cli .

By default most recent stable alpine rust image is used. To get nightly just run

docker build --build-arg RUST_IMAGE=rustlang/rust:nightly-alpine -t tinysearch/cli:nightly .
