Google, Bing or Yandex results as JSON with no API key: a headless Chromium on your own server reads them, and runs into the engines' CAPTCHAs and blocks.

Pagefind
Add full-text search to a static site without running a server: a Rust indexer runs after the build, and a search over 10,000 pages loads under 300 kB.
msgvault
Keep your own copy of your email and chat history: Gmail, IMAP, Slack and WhatsApp archived on disk, searchable offline and over MCP. Still alpha software.
Meilisearch
Typo-tolerant search-as-you-type for sites and apps: a Rust engine under MIT with hybrid vector search, where replication needs the paid Enterprise Edition.
