Websurfx aggregates results from multiple search engines into one private, ad-free interface that never tracks your queries. Written in Rust, the backend provides memory safety against buffer overflows and data races at the language level while handling concurrent requests across upstream providers like DuckDuckGo and Searx. A built-in re-ranking algorithm scores and merges results by relevance, producing a unified page that draws from many sources while appearing as one coherent search. Safe-search filtering operates across four levels from unrestricted to complete content blocking, with regex-based filter lists for parental controls in schools and organizations. Upstream requests route through configurable proxy chains or Tor, preventing search providers from correlating your queries with a specific IP address. Four Docker image variants target different caching strategies: hybrid Redis plus in-memory for maximum throughput, Redis-only, in-memory-only, or zero-persistence for environments where cached queries must never touch disk. The Lua configuration file controls engine selection, request timeouts, rate limiting thresholds, and production-mode delays that throttle upstream traffic to prevent abuse. Quick-result widgets handle calculations, currency conversions, and unit transformations inline without external redirects. Image search capabilities serve visual discovery for designers and researchers who need media results without surveillance. Runs on a RepoCloud VPS with dedicated resources and full root access. AGPL-3.0 licensed.

No database anywhere in the stack: Grav, the leading flat-file CMS, builds every page from a folder of Markdown and YAML on PHP, Symfony components, Twig templating, and Doctrine caching. That architecture is the whole argument: content is Git-versionable, rsync-able, and lock-in-free; pages render in well under 100ms without database round-trips; and backup means copying a directory. Content authors write Markdown (or plain HTML), configure with readable YAML, and define custom page structures via blueprint files that generate editing forms automatically. The optional Admin panel adds a polished editing layer: dashboard with site activity, page management with a syntax-highlighted editor and live preview, drag-and-drop media uploads, one-click plugin/theme updates, and normal/expert modes for form-based or raw YAML editing. The ecosystem runs deep - hundreds of open-source plugins and themes installed through the GPM package manager, with an event-hook architecture that gives plugins full control over the request lifecycle, and downloadable skeletons providing entire pre-built sites. Grav 2.0 modernizes the stack (PHP 8.3+, Symfony 7, Twig 3) and adds a first-party REST API, an MCP server for AI agents, and a SvelteKit single-page admin with real-time collaborative editing. Ideal for docs, blogs, and marketing sites. MIT-licensed.

Backed by Y Combinator and powering scraping infrastructure across 195 countries, Anakin delivers a production-grade web scraping API purpose-built for AI agents and RAG pipelines that need clean, structured data from sites that actively block conventional scrapers. The single Go binary server handles JavaScript-heavy SPAs through its Camoufox anti-detect browser service with automatic fingerprint rotation, while the HTTP-first handler chain tries lightweight extraction before escalating to full browser rendering — keeping response times under 2 seconds for static pages. The built-in React 19 dashboard provides visual scraping with live results, job tracking with status filters, domain configuration management with handler chain CRUD, and proxy performance monitoring via Thompson Sampling scoring. Structured JSON extraction leverages Gemini AI to transform raw HTML into typed schemas without manual selector maintenance. SDKs span Python, TypeScript, Go, .NET, Java, and Ruby, while the MCP server exposes all 21 tools directly to Claude, Cursor, Windsurf, and any Model Context Protocol-compatible agent. The hosted platform extends the open-source engine with AI web search returning full page content with citations, multi-source agentic research across 20+ sources per query, Wire pre-built actions covering 944 websites with 5,201 structured endpoints, persistent browser sessions for authenticated scraping, and website change monitoring with scheduled alerts. Deploy via Docker Compose with three containers or run the binary directly with optional PostgreSQL persistence. 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.

Used daily by millions of educators and learners in over 65 languages and embedded as the default virtual classroom in Moodle Cloud, Canvas, Sakai, D2L, Jenzabar, and Schoology — together comprising more than 75% of the worldwide learning management system market — BigBlueButton has been the leading open-source web conferencing platform for education since its creation at Carleton University in 2007. The platform delivers WebRTC-based real-time audio, video, and screen sharing with a tldraw v2-powered multi-user whiteboard featuring infinite canvas support, allowing multiple participants to annotate slides and draw simultaneously. Breakout rooms support up to eight concurrent groups with collaborative whiteboards enabled by default, and polling with customizable response types lets instructors assess understanding in real time. The built-in Learning Analytics Dashboard answers three questions at a glance: who is attending, who is participating, and who is learning based on poll responses, providing actionable engagement metrics without requiring webcam surveillance. Session recording captures audio, video, slides, chat, and whiteboard annotations for asynchronous playback on any device. The plugin architecture introduced in version 3.0 enables custom extensions, while IMS LTI 1.0 compliance allows integration with Blackboard, Desire2Learn, Pearson Learning Studio, and any conformant platform without custom code. The REST API enables programmatic session management, user authentication, and recording access for custom frontends like the included Greenlight application. Version 4.0 introduces LiveKit-based media and a redesigned interface. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. LGPL-3.0 licensed.

Grimoire captures, extracts, and indexes the content behind your bookmarks so you can search what pages actually say, not just their titles and URLs. The ingestion pipeline accepts links from the web UI, REST API, MCP server, browser bookmarklet, or bulk import, then fetches each page and extracts readable content using specialized parsers for GitHub repos, GitHub issues, StackOverflow threads, YouTube transcripts, PDFs, and standard web articles. Everything stores locally in SQLite with file-based content archives. Search operates in three modes: FTS5 keyword matching for exact terms, semantic embedding search for meaning-based retrieval using vector similarity, or a hybrid ranking mode combining both. Optional AI providers including OpenAI, Ollama, Anthropic, DeepSeek, and any OpenAI-compatible endpoint generate automatic tags, summaries, and embeddings without being required for core functionality. The interface built with React 18, Vite, TypeScript, Tailwind CSS, and Radix UI supports categories, nested tags, notes, archive and trash states, read-later flags, and multi-user isolated spaces. A single Bun-powered Hono process serves both the compiled frontend and the REST API on port 3210, requiring only one Docker container and a SQLite volume. Backup and restore export bookmarks, content, settings, and metadata as portable ZIP archives. Nearly 3,000 GitHub stars reflect growing adoption among developers and researchers. Running on a VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

GoatCounter delivers meaningful web traffic insights — pageviews, referrers, browsers, screen sizes, country-level geolocation — without setting a single cookie, without collecting personal data, and without forcing GDPR consent banners on your visitors. Written entirely in Go and distributed as a single compiled binary consuming roughly 25MB of RAM, it adds just 3.5KB to your pages via the tracking script, with a JavaScript-free tracking pixel alternative for sites that avoid scripts entirely, plus backend middleware integration and log file import for server-side collection. The dashboard displays pageview counts per path with hourly resolution, referrer sources grouped by domain with full URL on hover, browser and OS version breakdowns, screen size distributions, and country-level location data derived from IP addresses that are immediately discarded after geolocation. Campaign tracking supports UTM parameters and custom data attributes. A public stats option exposes your dashboard at a shareable URL for build-in-public transparency. SQLite serves as the default database requiring zero administration, while PostgreSQL handles higher-traffic deployments with multi-site setups. Built-in ACME and TLS certificate management eliminates reverse proxy requirements for HTTPS — no Nginx or Caddy needed. The REST API provides programmatic access to all analytics data. Deploy as a single binary, via Docker with the official arp242/goatcounter image, or through native packages. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. EUPL-1.2 licensed.

Personal, minimalist, database-free bookmarking - Shaarli is a philosophy as much as an app. Everything lives in a single compressed datastore file inside data/: no MySQL, no PostgreSQL, backup by copying one directory. That write-once/read-many file is usually served straight from OS disk caches, which is why a decade-old Shaarli instance with tens of thousands of links still responds instantly. Designed deliberately single-user, it saves URL, title, unlimited-length description, and tags (with autocomplete, renaming, and merging), marks entries public or private, and automatically strips utm_source and fb tracking parameters from saved URLs. That description field is why the community uses Shaarli as far more than bookmarks: a microblog, read-it-later queue, code-snippet base, pastebin, and shared clipboard between machines. Sharing is one click via bookmarklet or Android apps; consumption is per-tag RSS/Atom feeds plus a daily digest feed; search is full-text with tag filtering. A REST API opens it to any client, a plugin and theme system extends the PHP core (Markdown rendering, thumbnails), and import/export uses browser-standard Netscape HTML - your data enters and leaves freely. LDAP login is supported, no telemetry is sent anywhere, and the UI degrades gracefully without JavaScript. The anti-cloud Delicious.

Artalk embeds a full commenting system into any webpage with three lines of JavaScript, packing multi-site management, social login, spam filtering, and Markdown rendering into a client that weighs roughly 40KB. One server instance manages comments for unlimited websites with complete data isolation between sites, eliminating the need for separate deployments per project. The framework-agnostic Vanilla JS client renders a complete comment interface with Markdown support, LaTeX mathematical formula rendering, image uploads, emoji packs compatible with OwO format, and automatic dark mode detection. An integrated admin dashboard accessible through the comment box provides comment moderation queues, IP banning, comment pinning, page-level statistics, and content management without direct database access. Social login authenticates commenters through GitHub, Google, Twitter, Discord, and additional OAuth providers, while captcha protection spans four backends: image captcha, Cloudflare Turnstile, Google reCAPTCHA, and hCaptcha. Spam filtering layers include Akismet integration, keyword block lists, and cloud moderation services that catch unwanted content before publication. Email notifications support SMTP, Aliyun DM, and Sendmail transports with customizable templates, and multi-channel push notifications extend to Telegram, Bark, and other messaging platforms. The OpenAPI-documented HTTP API enables programmatic comment management. Database flexibility covers SQLite, MySQL, PostgreSQL, and SQL Server. A plugin marketplace offers community extensions for custom behavior. Continuously maintained for over 8 years. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Comments for small sites without Disqus's baggage: Cusdis is a lightweight, privacy-first, open-source comment system for embedding under blog posts and articles. The embedded JavaScript SDK is about 5 KB gzipped (Disqus is roughly 24 KB), sets no cookies, runs no tracking, and does not require readers to create an account or sign in before commenting. Integration is two lines: a container div with your app ID and an async script tag, with ready-made adapters for common frameworks and static site generators. Moderation is approval-based - new comments stay hidden until you approve them from the dashboard, and email notifications include a Quick Approve link that approves or replies to a comment from your phone without logging in. A webhook fires on every new comment for integrations like Telegram notifications. The widget ships with built-in i18n and dark mode. The stack is TypeScript and Next.js with a Prisma data layer, deployable via Docker with PostgreSQL. Deliberately minimalist: no ads, no reader profiling, and your comment data lives in your own database.

Named from the German "Ich schrei sonst" - roughly "or I'll scream" - Isso is a lightweight Python/JavaScript commenting server, a drop-in Disqus replacement for people who noticed what Disqus does to reader privacy and page load times. The design premise is printed right in the docs: comments are not Big Data. So the backend is a single SQLite file rather than a database cluster, and the entire client is one embeddable JavaScript file - 65 kB, 20 kB gzipped - that you drop into any static site, blog, or CMS. Commenters write in Markdown, need no account, and can edit or delete their own comments within a configurable window (15 minutes by default). Spam control comes from an optional moderation queue: held comments stay invisible until you activate them via an admin interface or email notification links. Migration is a first-class feature, with importers for Disqus and WordPress exports, so years of existing threads move over intact. Because everything is server-rendered from your own instance, no third party tracks your readers, and real-world switchers report smaller pages and faster loads than the Disqus embed. MIT-licensed, running since 2012.

WordPress without Gutenberg: ClassicPress, the community-led fork, keeps the TinyMCE classic editor as the default and strips the block editor and Full Site Editing out of core entirely. The result is roughly half WordPress's size - obsolete libraries like jQueryUI, Thickbox, and Flash support are gone, replaced by native HTML5 elements and modern alternatives like SortableJS - which translates to a measurably faster admin and a leaner attack surface. Forked from WordPress 6.2, it remains compatible with the vast plugin and theme ecosystem targeting that lineage (anything not requiring blocks generally works, helped by a blocks-compatibility mode), and the PHP-first WordPress API developers have used for over a decade works unchanged - no React required to extend your CMS. The fork adds its own improvements: built-in media categories and tags with bulk editing, revision management that lets you prune database bloat, native HTML5 dialogs for accessible touch-friendly menus, and recent releases bring APCu object-cache support, vanilla-JS core widgets, and performant translations. Governance is democratic and community-driven rather than corporate. For content sites, business sites, and blogs where the classic editing workflow is the feature, ClassicPress is stability as a philosophy.

Tau delivers a complete self-hosted cloud platform where Git is the control plane and WebAssembly is the runtime. The Go binary deploys as interconnected nodes that form a P2P network using libp2p for automatic service discovery, eliminating Kubernetes entirely. Serverless functions compile to WebAssembly for secure multi-tenant execution with automatic horizontal scaling — write in Go, Rust, AssemblyScript, or C and deploy by pushing to Git. Branch-based environments map Git branches to isolated deployments, so staging and production run identical infrastructure from different refs. Static website hosting serves frontends with global distribution and automatic content-addressed deduplication via IPFS-derived storage. The built-in K/V database provides distributed storage with automatic replication across nodes, while object storage handles file management with content addressing. Pub/Sub messaging enables real-time communication between functions and external services including WebSocket support. Spore Drive automates multi-host deployment and rolling updates from a single command across bare metal or VMs running Ubuntu. The Dream CLI provides a complete local development environment that mirrors production exactly — same services, same routing, same deployment flow. Zero-configuration HTTPS provisions TLS certificates automatically for custom domains. The web console at console.taubyte.com provides visual project management, or use the tau CLI for Git-native workflows. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD-3-Clause licensed.

When Commento's original maintainer went quiet, Commento++ bundled the community's bug fixes and stalled merge requests into a batteries-included release of the beloved Go-based Disqus alternative - and kept building. The core promise is unchanged: an embeddable comments box that is orders of magnitude lighter and faster than Disqus, with no ads, tracking, or data sales - two lines of HTML and a PostgreSQL database. On top of Markdown comments, voting, Disqus import, OAuth login (Google, GitHub, Twitter) plus SSO, sticky comments, thread locking, and email notifications, the fork's additions are substantial: WebSocket-powered live comment updates with permalinks and highlight animations for new arrivals, guest commenting with a name, a cross-domain moderation dashboard for approving and deleting comments in one place, MathJax rendering support, wildcard domain matching, a reInit hook that makes single-page-application integration clean, and Perspective API spam scoring alongside the existing Akismet integration. Optional page-view logging graphs traffic on the dashboard, native SSL termination works without a proxy, and script-tag data attributes control fonts, CSS overrides, deleted-comment visibility, and polling-versus-WebSocket behavior.

The social preview cards shown when links hit Twitter, LinkedIn, Slack, or Discord, generated on the fly: Oxigen is a small Go service for dynamic Open Graph images, no designer required per page. Instead of exporting static images per page, you compose a card once and drive it with parameters: title, author, website, logo, background image, and background dimming all arrive as URL query arguments, so your og:image meta tag simply points at the Oxigen endpoint with the page's own values substituted in. Every blog post, product page, and doc gets a branded, correctly sized preview generated on the fly. A built-in web UI covers interactive composition - tweak the text and imagery, watch the preview update, copy the resulting URL - while the same rendering path serves programmatic API use from static site generators, CMS templates, or build pipelines. Rendering is pure Go using the gg 2D graphics library, freetype fonts, and the imaging package, built on the kyoto framework by that project's author. Deployment is one stateless container on port 80 with no database and no external dependencies, so instances scale and restart freely.
