Project overview

Midscene.js drives interfaces from screenshots, so tests can describe actions and assertions in natural language instead of depending on fragile DOM selectors. It can target visual states, canvas elements, native applications, and cross-origin surfaces that structure-based automation may miss. Use the JavaScript SDK, YAML workflows, or a Chrome extension across browsers, Android, iOS, HarmonyOS, desktop apps, and custom interfaces.

Project overview

NextAI Translator works as a browser extension and a desktop app for Windows, macOS, and Linux. It can translate selected text or screenshots, polish writing, summarize content, and organize vocabulary across many languages. The app relies on a supported LLM provider, so users need to supply a compatible OpenAI, Azure OpenAI, or other available API key.

Project overview

Manage assets across Bitcoin, Ethereum, Solana, Tron, BNB Smart Chain, and other supported networks from one multi-platform wallet. Users can choose iOS or Android apps, desktop builds for macOS, Windows, and Linux, a web app, or a Chrome extension depending on where they work. The repository houses these clients alongside shared wallet logic and hardware-wallet components, making it most relevant to people who want an openly developed wallet experience across several device types.

Project overview

Import comic images, PDFs, EPUBs, CBRs, or CBZs into the desktop app, or use its Chromium extension while reading online. Comic Translate detects text, runs OCR, removes the original lettering, translates it, and renders the result back onto the page, with a manual mode for correcting failed detection or cleanup. Prebuilt apps are available for Windows and macOS, while GPU acceleration currently requires running from source.

Project overview

Elasticvue is an open-source graphical client for managing Elasticsearch data and cluster state. It is available as a desktop app, browser extension, hosted web app, or self-hosted deployment. Users can view a cluster overview, manage indices, aliases, and shards, search or edit documents, and run REST queries. Web and Docker-based use generally require Elasticsearch CORS configuration, while the desktop app needs less cluster-side setup.

Project overview

OpenAPI DevTools is a Chrome and Firefox extension that watches network traffic in a dedicated DevTools tab and builds an OpenAPI 3.1 specification as an application is used. It merges requests, responses, headers, bodies, query parameters, and configured path parameters, then lets users preview, export, or share the result. The repository now directs users to the rewritten successor, Demystify, for the expanded and final version.

Project overview

Demystify observes API traffic and generates OpenAPI 3.1 specifications from what it sees, including inferred path parameters and request or response details across status codes and MIME types. The desktop app captures traffic through a built-in proxy, the browser extension watches requests in a tab, and the CLI converts HAR files; a library is available for programmatic integration. It is useful for documenting APIs whose behavior is easier to observe than to describe manually.

Project overview

Tactus is a browser extension for Chrome, with a temporary Firefox debug-install path, that combines AI chat, page extraction, Agent Skills, and HTTP MCP tools in a sidebar. Users can import skills with instructions, scripts, and resources so the agent can understand the current page, call external tools, and automate repeatable workflows; first-time script execution requires confirmation. Conversation history and skill files are stored locally, but model and MCP calls still connect to user-configured external services through endpoints, credentials, or OAuth.

Project overview

IPFS Companion is a browser extension for Chromium-based browsers and Firefox that connects everyday browsing to a locally running Kubo node. It can handle ipfs:// addresses, redirect content-addressed sites and file paths to the local gateway, and provide quick actions for importing, pinning, unpinning, and copying CIDs or public gateway links. A local node must be running through IPFS Desktop or the command-line daemon.

Project overview

vault is a desktop organizer for links, Markdown notes, and original-quality images stored in ordinary local folders. Its browser extension sends saved content to the desktop app through a local API, where items can be grouped into folders or separate vaults, searched, renamed, pinned, imported, and exported. It works without an internet connection and does not include built-in synchronization, although users can sync the vault folder themselves with another storage service.
