Find open-source software you can trust.

Colanode combines team messaging, rich-text pages, structured databases, and file management in web and desktop clients that can connect to multiple servers and workspaces. Changes are written to local SQLite first and synchronized in the background, allowing continued work while offline and concurrent editing when teammates reconnect. Self-hosting requires Postgres, Redis, and a file storage backend. The hosted web client is currently described as an early preview and may still have browser compatibility issues.

Koharu combines text and speech-bubble detection, OCR, inpainting, translation, and typesetting into a manga translation workflow. It handles vertical CJK and right-to-left text and can export layered PSD files with editable lettering. The app runs with a GUI, headless server, or MCP interface, using either local llama.cpp models or remote providers on Windows, macOS, and Linux.

Mouser lets you customize Logitech HID++ mice with button mappings, gestures, DPI controls, Smart Shift, and profiles that change with the foreground app. It runs locally on Windows, macOS, and Linux without telemetry or an account, but Logitech Options+ must be closed; macOS and Linux also require the relevant system permissions.

Teams for Linux wraps the Teams web app in an unofficial desktop client with notifications, tray integration, screen sharing, custom backgrounds, and multiple account profiles. It is designed primarily for Linux and can be installed through common distribution packages or release builds. Some behavior remains limited by the Teams web experience, and the app disables Electron's built-in context isolation and sandboxing, so security-conscious users should consider running it through Flatpak, Snap, Firejail, or another system-level sandbox.

Streamlabs Desktop is free and open-source live-streaming software built on OBS. It provides a desktop application for creators who want to prepare and run broadcasts through the Streamlabs workflow. The documented application support is limited to 64-bit Windows and macOS 10.14 or newer, so Linux users are not covered by the stated platform compatibility.

Frappe Books is an open-source desktop accounting application for Windows, macOS, and Linux, built around double-entry bookkeeping. It handles invoices, bills, payments, journal entries, and point-of-sale activity, stores financial data in a local SQLite file for offline use, and produces reports including the general ledger, profit and loss statement, balance sheet, and trial balance.

Franz 5 combines services such as WhatsApp, Slack, Telegram, and other messengers in one desktop application, reducing the need to switch between separate clients. This repository contains the open-source predecessor to Franz 6 and is no longer the active product codebase. It remains useful for source reference or self-building, while the current Franz application is distributed separately through the official website.

Ueli is a cross-platform keystroke launcher that opens with a hotkey, searches available items, and launches the selected result. Favorites, additional actions, settings, and optional extensions add shortcuts for common workflows on Windows, macOS, and Linux. The project notes that downloadable Windows binaries may be unsigned and macOS binaries are unsigned and unnotarized, so the operating system may block the first launch.

JabRef is a cross-platform reference manager for BibTeX and BibLaTeX libraries. It can import records from scientific catalogs or identifiers, extract metadata from PDFs, organize collections and attachments, merge duplicates, and insert citations into external writing tools. Browser extensions help capture new references, while teams can synchronize a library through SQL; a separate JabKit command-line interface is also available.

Imagine is a desktop image optimizer for preparing graphics for the web or reducing everyday asset sizes. Its graphical interface can batch-compress PNG, JPEG, and WebP files and convert between supported formats. Prebuilt releases are available for Windows, macOS, and Linux, making it suitable for users who prefer not to assemble a command-line compression workflow.

Open Claude Cowork combines a desktop work assistant with a messaging-based personal assistant. The desktop app supports persistent chats, streamed responses, visible tool activity, and custom skills, while the companion bot connects through WhatsApp, Telegram, Signal, or iMessage for reminders, memory, and browser tasks. Both use Composio integrations and require Anthropic and Composio API keys.

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.

Webtop delivers full Linux desktop environments through a modern browser, making it useful for remote workstations, administration, or temporary development desktops. Choose from several distribution and desktop combinations, then run the image with Docker and persist its configuration through mounted storage. The container has no internet-grade authentication by default, and anyone with GUI access can obtain root privileges inside it, so public exposure requires HTTPS, a secured reverse proxy, and strong access control.

QQ Chat Exporter saves direct and group conversations as HTML, JSON, TXT, or Excel while also downloading associated images, videos, and stickers. Reading and parsing are performed on the user's computer rather than through a project-hosted server. Windows users can choose a packaged installer, Windows and Linux support a shell workflow, and Docker deployment is available across macOS, Linux, and Windows. Apple Silicon systems run the relevant Docker component through Rosetta.

CompressO is a desktop app for reducing video and image file sizes on Windows, macOS, and Linux. Compression runs locally, with no network requests other than built-in update checks. Installers are available from the releases page, and macOS users can also use Homebrew; the macOS build is not notarized and may trigger Gatekeeper warnings when installed directly.

CodexMonitor gives developers one desktop interface for running Codex across multiple workspaces, tracking active or unread threads, and isolating parallel tasks in worktrees. It also brings file browsing, Git diffs, and GitHub issues and pull requests into the same workflow. A local Codex CLI installation is required, while an optional daemon can run the backend on another machine.

LDtk is an open-source 2D level editor designed to give game developers a clear visual workspace for creating and maintaining levels instead of working directly with underlying data files. Users can get the latest version from the project website, while contributors can build it from source. LDtk can also run inside a Hide editor tab as an embedded plugin.

Zen runs a local system proxy on Windows, macOS, and Linux to block ads, tracking scripts, malware, and other unwanted requests from browsers, desktop applications, and operating-system components. Users can inspect blocked requests and the rule that matched, then use bundled filters or add hosts files and EasyList-style lists. The first run requires installing a root certificate generated locally so HTTPS traffic can be inspected. On Linux, automatic proxy configuration is currently limited to GNOME- and KDE-based desktops.
