Find open-source software you can trust.

Plausible provides privacy-first web analytics through a lightweight script and a focused, single-page dashboard. It measures traffic and events without cookies, persistent identifiers, stored IP addresses, or personal profiles, which can reduce consent and compliance overhead for many sites. Users can choose the paid managed cloud service for a maintained setup or deploy the free Community Edition themselves. Self-hosting offers control but leaves infrastructure, security, backups, and upgrades to the operator.

Karakeep gives you a self-hosted place to collect links, quick notes, images, and PDFs for later use. It fetches page metadata automatically, supports lists and collaboration, and makes stored content searchable through full-text search and OCR. Optional language-model features can tag and summarize items, including through locally hosted models with Ollama.

PicGo uploads images by drag and drop, from the clipboard, or with hotkeys, then copies the resulting link in Markdown, HTML, URL, or a custom format. It supports several hosting providers directly and extends to services such as S3, Cloudflare R2, and MinIO through plugins, with an HTTP API for integrations.

Dashy gives homelab and self-hosting users a central homepage for launching services, checking their status, and viewing information through widgets. It supports multiple pages, search and keyboard shortcuts, extensive themes and icons, a UI editor, and optional multi-user authentication with configurable privileges. Docker is the common deployment path, while several cloud platforms are also supported. Persistent deployments need a user-data directory containing at least the main configuration file.

Zulip is an open-source team chat server and web application built around topic-based threads. Messages stay grouped by subject, helping teams combine real-time discussion with asynchronous work without losing the surrounding context. The project is used by remote teams and open-source communities, and organizations can try the public development chat or follow the documentation to run their own service.

Responsively App is an Electron-based browser for testing responsive layouts across several device profiles at once. It mirrors interactions between previews, provides a customizable arrangement and a shared element inspector, includes more than 30 built-in profiles plus custom devices, and captures screenshots across every preview in one click. Hot reloading is supported on Windows, macOS, and Linux.

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.

Meetily records and transcribes meetings on your device, keeping recordings, transcripts, and transcription models local for privacy-sensitive work. Summaries can stay fully local through Ollama or use Claude, Groq, OpenRouter, or a custom OpenAI-compatible endpoint. Installers are available for macOS and Windows, while Linux users build from source.

Dockge manages compose.yaml-based stacks through a web interface for creating, editing, starting, stopping, restarting, and updating services, with live progress and terminal output. Compose files remain in a normal directory structure and can still be used with standard Docker Compose commands, while agents can connect multiple hosts. It targets Linux stack management and is not intended for standalone containers without compose.yaml.

Beszel collects server and Docker or Podman metrics through a central web hub and a lightweight agent installed on each monitored system. Its dashboard records historical CPU, memory, disk, network, temperature, GPU, and container data, with configurable alerts for operational thresholds and outages. The self-hosted platform also supports multiple users, OAuth or OIDC authentication, and automatic backups to local disk or S3-compatible storage.

Open Generative AI combines image, video, audio, lip-sync, and workflow tools in a shared creative interface. Users can call hosted models or connect local inference engines, with desktop installers for macOS, Windows, and Linux as well as a hosted browser version. Cloud generation generally requires an account and API key, while local models require suitable hardware and additional runtime setup.

DevSidecar uses DNS selection, a local proxy, and SNI handling to improve access to GitHub pages, source files, releases, and Git clone operations, and it can also proxy npm or switch registries. Its default mode installs a locally generated root certificate and enables interception. A certificate-free safety mode is available, but it offers fewer capabilities and less consistent connectivity.

Readest opens EPUB, MOBI, AZW3, FB2, CBZ, TXT, and PDF files across macOS, Windows, Linux, Android, iOS, and the web. Readers can switch between scrolling and paginated layouts, search within books, add bookmarks, highlights, and notes, look up terms, or place two documents side by side. It is designed for people who want a consistent reading workflow across several device types.

Navidrome serves a personal music collection through a responsive web player and compatible mobile clients. It supports large libraries and multiple users with separate play counts, playlists, and favorites, while monitoring files and metadata for changes. Binaries are available for macOS, Linux, Windows, Docker, and Raspberry Pi; the project recommends tagged releases rather than a potentially unstable development branch.

opcode provides a desktop command center for Claude Code, combining project and session management with custom or background agents, usage tracking, MCP server controls, checkpoints, and CLAUDE.md editing. On first launch it detects the existing ~/.claude directory, so users can keep their native Claude Code configuration while working visually. The Claude Code CLI must still be installed and available on the system.

listmonk is a self-hosted application for managing newsletters, mailing lists, subscribers, and email campaigns from a web dashboard. It is distributed as a single binary and stores its data in PostgreSQL. You can deploy it with the provided Docker Compose setup or download a release, generate a configuration file, initialize the database, and run the service directly. It suits teams that want to manage their newsletter tooling and subscriber data themselves.

GitHub Desktop puts common Git work such as reviewing changes and creating commits into a graphical app for people who prefer not to live in the command line. Official installers and beta builds are available for macOS and Windows; Linux is not officially supported and relies on community-maintained releases.

Kap starts from the macOS menu bar: choose the portion of the screen to capture, begin recording, and click the icon again to stop. Option-clicking pauses an active recording. Builds are available for Apple silicon and Intel Macs, with Homebrew installation and a plugin system for extensions.
