Hister

Helium is a privacy-focused, Chromium-based web browser developed as a heavily modified version of ungoogled-chromium. It provides unbiased ad blocking, removes tracking components, and is designed without added bloat or noise. The project publishes native packages for macOS, Linux, and Windows, with downloads available from its website and source, packaging, tooling, services, and components available on GitHub. Helium is currently in beta. Helium-specific code, patches, and other original content are licensed under GPL-3.0, while imported components retain their original licenses.

Search is a small, fast WebKit browser for macOS developed by Office Commun. It provides a single address-and-search field, tabs, reading mode, picture-in-picture video, bookmarks, history, downloads, built-in ad and tracker blocking, per-site clutter hiding, and password storage in the macOS keychain. It has no account, sync, cloud storage, telemetry, or analytics; browsing data remains on the Mac. The browser uses WebKit and lazily creates each tab's web view, while its ad blocker runs as a compiled WKContentRuleList before network requests are made and its hidden-element rules are injected at document start. It can run Chrome extensions through WebKit's extension engine, adding shims for Chrome APIs that WebKit lacks; extension support requires macOS 15.4 or later. Search supports macOS 14 or later, is distributed as a free download of about 3 MB or through Homebrew, and is licensed under the MIT License. The repository contains a Swift and SwiftUI/AppKit implementation with no dependencies beyond Apple's macOS frameworks.

Lunr.js is a small, browser-based full-text search library developed in the olivernn/lunr.js project. It indexes JSON documents locally and provides a search interface that returns matching document references, relevance scores, and match metadata; it can generate the search index used by static sites such as microblogs. It supports field-specific searches, query-time term boosting, document-level index boosting, wildcard and edit-distance fuzzy matching, and full-text search in 14 languages. The library can be included directly in a web page or installed through npm, and is intended for client-side searching without a server-side search service or network connection.

Harper is an offline, privacy-first English grammar checker developed by Automattic and written in Rust. It analyzes drafts locally, with a low memory footprint, and can be loaded through WebAssembly. The project provides integrations for Visual Studio Code, Neovim, Helix, Emacs, Zed, Obsidian, Chrome, and other browsers, along with a language server and a JavaScript package. English is currently supported, while the core is designed to be extensible to other languages.

Jev Search is a web search application built by Search1API that uses TypeSafe's Jev to interpret plain-language requests, select search terms, sources, and time ranges, and rank results. It queries general and vertical search engines concurrently, merges results by URL, engine agreement, original rank, and Jev relevance scores, and returns links and snippets with editable filters rather than generated answers. The application streams results as search lanes finish, reports failed sources separately, and can be installed as a browser app; it requires a network connection for searches. The open-source application is MIT licensed and can be self-hosted on Cloudflare Workers with Search1API and a Jev provider such as TypeSafe, Vercel AI Gateway, or Cloudflare Workers AI.
