Vale 3.26.0 ڈاؤن لوڈ

## Vale in the browser

v3.26.0 is the first release that ships Vale as a WebAssembly module. It's the same engine as the CLI, built for a JavaScript host：a browser, a browser extension, or Node. It runs with no server and no filesystem.

Each release now includes `vale_3.26.0_wasm.tar.gz`, which holds `vale.wasm` and the `wasm_exec.js` loader that matches it. The host passes the `.vale.ini` as a string and loads styles, vocabularies, and packages into an in-memory filesystem. Vale then lints:

• Markdown, MDX, MyST, Quarto, Org, HTML, and plain text, natively.
• YAML, JSON, and TOML, through Views.
• AsciiDoc, XML, and any other converted format whose HTML the host produces with a JavaScript converter. `ValeConverterOptions` returns the arguments that make that HTML match what the CLI would produce.

`ValeSuggest` resolves an alert's fixes, and `ValeResolveConfig` reports which rules each section turns on, turns off, or changes the level of. Source-code linting needs tree-sitter, which uses CGo, so it stays CLI-only.

See the [WebAssembly docs](https://docs.vale.sh/topics/wasm) for the full API.

## Thank you, FLOSS/fund

Vale received a $10,000 grant from [FLOSS/fund](https://floss.fund/blog/second-tranche-2025-anniversary/) to support Vale's expansion to the web. Grants like this keep Vale free and independent. Thank you to FLOSS/fund for supporting open-source infrastructure.
