FCaptcha guards your forms with an invisible check that spots bots, headless browsers, and AI agents steering real browsers, all from a server you run yourself. Drop the widget into a signup or contact form and it quietly watches how the visitor actually behaves: pointer movement, typing cadence, scroll shape, and dozens of other signals that separate a person from a script. Vision agents that screenshot and click, and computer-use agents driving a browser through automation protocols, leave input traces the scoring engine catches. Self-declaring crawlers get flagged by name, and signed agent requests are verified cryptographically so polite, identified bots can be allowed while anonymous automation is blocked. A proof-of-work challenge adds a liveness gate behind the scenes. Humans see no puzzle at all, in any of 34 languages, and the widget meets accessibility standards for screen-reader and keyboard-only visitors. Your backend verifies each token through the same siteverify contract that Turnstile, reCAPTCHA, and hCaptcha use, so switching providers is a change of address rather than a rewrite. No cookies are set, no visitor data travels to a third party, and nothing phones home.

Give your coding agents a board they can work, not just read: Kanzo is a self-hosted kanban board where you and your agents move the same tasks through the same columns at the same time. Tell an agent to take the next task and it moves the card to doing, comments as it works, and leaves the result where you can read it in the browser. Projects follow the code automatically: the agent finds the right board from the Git remote of the repository it is working in, and you can link more repositories to a project from its menu. Press n to add a task, search every project with a slash or Command-K, paste an image straight into a card or comment, and park half-formed ideas in an optional Backlog column that agents leave alone until you promote them. The whole board is one folder, and a private Git repository you own keeps it in step across a laptop, a desktop, and a Raspberry Pi, with conflicts resolved by choosing which side to keep. Statuses are yours to rename in the config file, the board exports cleanly to Markdown or JSON, and one click in the sidebar installs updates and restarts the service.

Livebook is an interactive notebook for Elixir where you write code alongside rich Markdown prose, execute it cell by cell with reactive dependency tracking, and deploy finished notebooks as standalone web applications with a single click. Nearly 6,000 GitHub stars reflect the Elixir core team's investment in a platform where code cells run on demand alongside Mermaid diagrams and KaTeX mathematical formulas. The Kino visualization library renders Vega-Lite charts, interactive data tables with sorting and pagination, Leaflet maps, and Mermaid diagrams directly within notebook output cells, while custom Kino components enable building interactive controls with sliders, text inputs, and buttons that feed values back into running code. Smart cells abstract high-level tasks into configurable UI widgets: query PostgreSQL, MySQL, SQLite, and BigQuery databases, train machine learning models with Axon, plot charts, and build map visualizations without writing boilerplate code. Real-time collaboration lets multiple users edit the same notebook simultaneously with cursor presence indicators and synchronized cell evaluation. Notebooks are stored as .livemd files, a Markdown-compatible format that renders cleanly on GitHub and integrates with standard version control workflows. Custom runtimes connect Livebook to existing Elixir applications for live introspection and documentation of running systems. The Docker image at ghcr.io/livebook-dev/livebook exposes ports 8080 and 8081 with password or token authentication.

Backed by nearly 80,000 GitHub stars and recognized as one of the most popular developer tools in the open-source ecosystem, Hoppscotch delivers a complete API development platform that runs instantly in any browser with zero installation. The platform supports six protocols out of the box including REST with full HTTP method coverage, GraphQL with schema introspection and multi-column documentation, WebSocket for full-duplex communication, Socket.IO, MQTT for IoT messaging, and Server-Sent Events for real-time streaming. Request collections organize your API calls into logical groups with support for sub-folders, environment variables with scope inheritance, pre-request scripts and post-request test scripts written in JavaScript, and automatic code snippet generation in over twenty languages and frameworks. Teams can collaborate in real-time with shared workspaces, role-based access controls, and cloud synchronization across devices. Migration from Postman, Insomnia, or OpenAPI specifications happens with a single click import. The self-hosted edition deploys via Docker Compose with PostgreSQL for data persistence, supporting SSO authentication through SAML and OAuth providers, SMTP configuration with OAuth2, and admin dashboard for user management. The platform also ships as a native desktop application for macOS, Windows, and Linux with offline support, plus a CLI tool for running collections in CI/CD pipelines. A built-in proxy mode bypasses CORS restrictions during development, and an interceptor enables request debugging and response modification.

Up to 280 search services - Google, Bing, DuckDuckGo, Brave, Qwant, Startpage - aggregated without tracking or profiling: SearXNG is a privacy-respecting metasearch engine (AGPL-3.0, successor to Searx). Your instance queries the upstream engines on your behalf: your IP address, cookies, and search history never reach them, tracker parameters are stripped from result URLs, and an optional image proxy fetches thumbnails server-side so result pages leak nothing. It can even route outbound queries through Tor for full anonymity. Search is organized into categories - general, images, videos, news, maps, music, IT, science, files - with bang shortcuts for targeting specific engines, and every source can be enabled, disabled, or weighted per category in settings.yml. A plugin system adds calculators, hash tools, tracker removal, and unit conversions inline, and preferences (themes, safe search, languages, engine selection) persist in cookies rather than server-side accounts. The real argument for running your own instance rather than trusting a public one is control: you decide the logging policy (none), the engine mix, rate limiting, and who gets access - making it the default search backend for browsers, families, and teams that want Google-quality results without the profile.

Fluxer gives friends, gaming groups, and private communities their own self-hosted instant messaging and VoIP platform that replaces Discord with private text channels, voice rooms, video calls, and screen sharing. Members can chat one-on-one in direct messages, form multi-person group conversations, or organize large community servers into categorized text and voice channels with threaded replies, reactions, and typing indicators. When a conversation moves to voice, participants can join low-latency audio and video rooms from multiple devices simultaneously, share application windows or full screens, and rely on built-in noise suppression and echo cancellation for clear calls. Rich media support allows users to share file attachments, preview embedded links, search animated GIFs through KLIPY, and upload custom community emojis and stickers. Server administrators control access through role-based permission hierarchies, member timeouts, kicks, bans, and detailed moderation audit logs that track every configuration change across the community. Integrated full-text search lets members quickly locate historical messages, code snippets, and shared files across every channel they can access.

Moltis gives individuals and teams a completely private personal AI agent server that bridges conversational assistants to everyday messaging platforms while executing real-world computing tasks inside secure execution environments. Users can interact with autonomous agents across Telegram, Discord, WhatsApp, Slack, Matrix, and browser interfaces to draft correspondence, automate research, and schedule recurring cron tasks. The system coordinates multi-agent delegation by spinning up specialized sub-agents with dedicated roles for code generation, pull request reviews, quality assurance testing, and technical documentation. Built-in sandboxing isolates tool operations within container boundaries or WebAssembly modules, ensuring shell commands, web scraping routines, and script executions cannot alter underlying operating system files without explicit permission. Native Model Context Protocol integration allows operators to attach external data endpoints, database connectors, and custom command-line utilities without rewriting core routing logic. Persistent memory preserves conversational context and document embeddings across multiple sessions, allowing assistants to recall prior discussions, user preferences, and project guidelines indefinitely. Administrators can configure granular tool approvals, manage WebAuthn passkey authentication, and review real-time WebSocket communication logs through an embedded control panel.

Watch YouTube without the ads, accounts, or tracking, from a server you own: TubeHaus is a private YouTube client that keeps the familiar layout, URLs, and keyboard shortcuts. Your subscriptions, watch history, resume positions, Watch Later, and playlists live as files on the server, so every device in the house shares one library and picks up a video where another screen left it. Live streams play with segments fetched ahead of the player, and captions are transcribed on the fly when a stream has none. Chapters, storyboard previews, a mini player, and theater mode make long videos easy to navigate, while sponsors are skipped automatically and dislike counts come back to the page. Save videos offline in 1080p or 4K for trips, send playback to a TV from your phone without a separate casting dongle, and drive the television interface entirely from a remote. Imports arrive from a Google Takeout export, Invidious, NewPipe, or FreeTube, so years of subscriptions move over in minutes instead of being rebuilt by hand. A calm mode hides recommendations and Shorts when you only want to search and watch deliberately.

Manage My Damn Life is a personal productivity platform and CalDAV task manager that gives individuals and teams a full-featured web workspace for coordinating todos, calendar agendas, and project schedules without relying on proprietary productivity software. Users can connect multiple CalDAV server backends including Nextcloud, Radicale, and Baikal to synchronize tasks, events, and subtasks across their self-hosted infrastructure. The interface offers multiple interactive perspectives, letting planners switch between nested task checklists, full monthly calendar grids, and dynamic Gantt chart roadmaps with customizable timeline scales. Keyboard-driven operators can rapidly log action items via intuitive Quick Add syntax that parses due dates, priority tiers, and category labels from inline text triggers. A versatile filter manager allows users to save custom query views matching due dates, completion statuses, parent task hierarchies, and color-coded labels. Team members can establish reusable task templates for recurring administrative workflows, assign multi-level checklist items, and manage individual calendar visibility across shared workspaces. System administrators can configure user authentication through native accounts or integrate enterprise Single Sign-On using OpenID Connect providers like Keycloak, Authentik, and Google. Client-side state caching accelerates navigation while background sync preserves CalDAV compliance.

OpenPost is an open-source content creation and publishing suite that unifies multi-platform social scheduling, graphic design, and video editing into a single self-hosted control center. Creators can compose one primary announcement and tailor bespoke copy, media attachments, and thread structures across sixteen distinct networks including Bluesky, Mastodon, X, Threads, LinkedIn, YouTube, and Discord. The integrated browser canvas lets you design multi-slide carousels with custom typography, layer ordering, and automated background removal without juggling external design software. A built-in multitrack video suite allows you to trim footage, render subtitle captions, insert transitions, and slice clips directly by highlighting spoken words in generated transcripts. Social managers can organize campaigns through an interactive visual calendar, stagger deliveries across automated queues, and monitor unified comment streams to answer incoming audience inquiries directly from a single inbox. Teams can organize multiple independent client brands into partitioned workspaces with role-based permissions, automated repost policies, and programmable scheduling webhooks via native REST and Model Context Protocol endpoints.

New API is a Go-powered LLM gateway that funnels over 40 AI providers, from OpenAI and Anthropic to Google Gemini, Azure, AWS Bedrock, DeepSeek, and Mistral, through a single OpenAI-compatible endpoint with intelligent routing and enterprise cost controls. Bidirectional format conversion translates between OpenAI Chat Completions, Claude Messages, and Gemini GenerateContent APIs transparently, so clients call any provider using their preferred format while the gateway handles the rest. Routing logic supports weighted random channel selection, priority-based failover, and automatic retry on provider errors to maximize uptime. The React admin dashboard shows usage charts, token consumption tracking, per-model cost breakdowns, and real-time request monitoring. Multi-tenant architecture includes three role levels, token-based authentication, per-user quota management, and a three-phase billing system with tiered pricing via a custom expression language. Multimodal support covers text completion, vision, embeddings, text-to-speech, speech-to-text, image generation, and creative task providers like Midjourney-Proxy and Suno-API. The interface ships in five languages including English, Chinese, Japanese, and French. Docker deployment runs with SQLite or MySQL for persistence. 45,000+ GitHub stars. AGPL-3.0 licensed.

Emailed copies of the same document, each with a different filename and a different set of edits, are where collaborative writing goes to die. LibrePaper keeps one living document in the browser instead: start a project in HTML, Markdown, Typst, LaTeX, or Quarto, or upload an existing one, and the editor renders the compiled result beside the source as you type. Readers highlight the exact passage they mean and comment on it, suggested edits land as tracked changes, and threads resolve on the text in real time. Finished work publishes to its own separate host, so scripts and interactive figures inside a document can never reach a reader's sign-in session. Nobody manages another password: sign-in runs through GitHub, Google, Microsoft Entra ID, ORCID, or any OpenID Connect provider, per-provider lists decide who may publish and who may only comment, and anonymous comments can be switched on for outside reviewers. Every project exports as a complete, independent copy from the command line, which also administers the deployment and can serve a document's tools to an AI agent over MCP. Operators get graphs, account management, and moderation, with per-account storage quotas, upload limits, and retention rules keeping a public instance under control. Four Docker containers behind Caddy with automatic HTTPS, one configuration file, and nightly backups of database and files complete the deployment.

AI and API products live or die by usage, and OpenMeter is the open-source stack that measures it, rations it, and bills for it. Your application emits CloudEvents for every billable action; OpenMeter validates and deduplicates them, then aggregates usage in real time so dashboards and enforcement checks never wait for a nightly batch. Meters slice that usage by customer, time window, or any dimension you attach, which turns raw events into answers like tokens per workspace this month. Entitlements decide who gets what: metered allowances with balances and overage, boolean switches for features like SSO, and static JSON configuration for per-customer model access. Grants top allowances up once or on a schedule, resets roll balances over each usage period, and one API call tells your app whether a customer still has access right now. On the money side, plans carry flat, per-unit, tiered, package, or dynamic prices; subscriptions, credit balances, and the invoice lifecycle run alongside, with webhooks announcing everything to your other systems.

Deployed at thousands of enterprises across financial services, healthcare, government, and telecommunications, Apache NiFi is the industry-standard platform for building automated data pipelines through a visual drag-and-drop browser interface that requires zero coding for common integration patterns. The flow-based programming model connects over 300 built-in processors covering relational databases via ExecuteSQL and PutDatabaseRecord, Apache Kafka with PublishKafka and ConsumeKafka, HTTP endpoints through InvokeHTTP and ListenHTTP, cloud storage for AWS S3, Azure Blob, and Google Cloud Storage, SFTP/FTP file transfers, and JSON, XML, CSV, and Avro transformations. Data provenance tracking logs every routing decision, transformation, and delivery for every FlowFile, creating a searchable lineage graph from source to destination with full content replay capability for auditing and debugging. Guaranteed delivery uses configurable backpressure thresholds, prioritized queuing with latency or throughput optimization, and automatic retry with exponential backoff, ensuring no data loss even during downstream outages. The zero-leader clustering architecture distributes processing across nodes with automatic load balancing, while site-to-site protocol enables secure data transfer between NiFi instances across network boundaries. Security includes OpenID Connect and SAML 2.0 single sign-on, role-based access control with fine-grained policies per component, and TLS encryption for all communication. Custom processors can be written in Java and packaged as NAR bundles, or implemented directly in Python through the native scripting framework.

Software makers who would rather not rent a licensing backend use Keygate to issue, sell, and enforce license keys from infrastructure they control. You create desktop, SaaS, or hybrid products and sell them as subscriptions, perpetual licenses, perpetual licenses with a maintenance period, trials, or floating concurrent licenses that are checked out, heartbeated, and returned automatically. The admin dashboard manages products, plans, customers, licenses, API keys, webhooks, analytics, audit logs, team members, email templates, and branding, with search, filters, and CSV or JSON export. Your application activates and verifies keys through the license API, enforces per-device or per-user activation limits with grace periods, and can verify Ed25519 signed tokens offline with a public key. Usage metering tracks API calls, storage, bandwidth, or custom metrics against quotas with hourly, daily, monthly, or yearly reset cycles and webhook threshold warnings. Connecting Stripe makes checkout create licenses automatically, follows plan and seat changes with proration, handles refunds and cancellations, sends dunning emails after failed payments, and gives customers a billing portal and self-service license management. Team seats, feature entitlements, purchasable add-ons, scoped API keys, and optional S3-backed release hosting round out the selling stack in one binary with one PostgreSQL database. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

SolidInvoice ships a complete billing platform as a single FrankenPHP binary — no separate PHP installation, no web server configuration, just one executable that delivers quote-to-invoice conversion, automated recurring billing, Stripe and PayPal payment processing, multi-currency precision arithmetic, and eight render-ready PDF templates out of the box. Maintained since 2012 across 63 releases with 30 contributors, the Symfony 7 and PHP 8.4 backend provides quote creation with one-click conversion to invoices, recurring billing with configurable frequency schedules, and online payment processing through Payum supporting Stripe, PayPal, and additional gateways. Multi-currency support uses real Money objects for precision arithmetic, while multi-tax support handles invoice-level and line-item tax rates with automatic calculation. Client management stores contacts, multiple addresses with map integration, credit balances, and complete quote and invoice history per client. The redesigned Tabler-based UI features a dashboard with hero statistics, ChartJS revenue trend visualization, attention-required alerts for overdue and draft invoices, quick actions, and a recent activity timeline. A RESTful API enables integrations with external systems. Multi-channel notifications deliver alerts via email, SMS, and webhooks. Google OAuth and two-factor authentication secure access. Grid export and full company data export support backup and migration. Deploy using Docker, Homebrew, the standalone FrankenPHP binary, or from source.

Every email account you own lands in one combined inbox with Cypht, putting Gmail, Outlook, a work Exchange server, and your RSS feeds behind a single login. Combined views do the heavy lifting: one inbox, one unread list, one sent folder, and one flagged list span every connected account, and each account still keeps its own folder tree when you need to work inside a single mailbox. Messages move freely once they are together: search across all accounts at once, then copy or move mail between accounts, flag favorites, and clear out large mailboxes from the same list. Sending identity stays organized through profiles, which pair an incoming account with an outgoing SMTP server and attach a signature and reply-to address, so the right name and footer go out with every message. New accounts connect over IMAP, JMAP, or Exchange Web Services, and provider auto-discovery fills in server settings for major services instead of making you look up ports. Everything is a module set, so LDAP authentication, folder sharing, and integrations like WordPress and GitHub can be switched on or left out entirely. Pages stay small and quick on modest connections, which suits the ISPs, schools, and small teams Cypht was built for. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. LGPL-2.1 licensed.

Hand a task to an AI teammate the way you would hand it to a person: describe the work, then follow along and step in when it matters. UseAgent runs Claude Code, Codex, OpenCode, and Pi inside isolated Linux workspaces, each with your repositories, a terminal, a real browser, and a desktop you can open and take over. Start work from the web app, by mentioning an agent in Slack, or through the API, and get pull requests, documents, spreadsheets, presentations, and research back as usable files. Four engines share one thread and one event format, so you can compare how Claude Code and Codex each handled the same bug, then switch engines on the next reply without losing history, files, or memory. Risky operations pause at approval gates, and a decision resumes the run with a one-shot, argument-bound capability instead of blanket trust. Every step, tool call, and approval is stored as an append-only event log in your Postgres, replayable after the fact and durable across restarts mid-task. Teach the workspace your procedures by importing versioned skills from GitHub and pinning playbooks to tasks, while knowledge pages and optional team memory stay beside the work, inspectable and correctable. Recurring tasks run on schedules with full history. Provider keys stay on your server and never enter an agent sandbox.
