Any blog, documentation site, or static website can host a complete comment section by running its own Waline server, with Markdown, emoji, reactions, and moderation tools included. A visitor writes as a guest, registers an account, or signs in with GitHub, Twitter, Facebook, Weibo, or QQ, and a live preview shows the formatting before anything is posted. Comments accept tables, strikethrough, highlighted code blocks, TeX formulas, custom emoji packs, and Giphy GIF search. On submission, a sanitizer strips scripts and styles while Akismet, per-IP rate limits, keyword and IP block lists, duplicate detection, and reCAPTCHA or Turnstile screen for spam, and an optional review queue holds the comment back until a moderator approves it. The site owner then hears about it by email, WeChat, QQ, Telegram, PushPlus, Discord, or Lark, and the commenter receives reply emails. Once published, readers react with up to nine emoji and sort threads by latest, oldest, or hottest, while pageview and comment counters can appear anywhere on a site and recent-comment and top-commenter widgets fill sidebars. Moderators edit, approve, flag, or delete from the web admin panel, manage users and custom labels, and import earlier discussions from Disqus, Twikoo, Valine, Typecho, Artalk, Commento, or WordPress. Comments stay in your own database, and the widget offers a dark theme and ten languages.

Execute comprehensive multi-angle investigations across scientific journals and web repositories using Local Deep Research, an autonomous intelligence engine designed for researchers, analysts, and knowledge workers. Users can submit complex analytical questions through a self-hosted web console to initiate agentic research cycles powered by LangGraph workflows. The application dynamically queries search providers including SearXNG, arXiv, PubMed, Wikipedia, and Google, iteratively evaluating discovered content to formulate targeted follow-up queries. Discovered academic papers and web sources can be indexed into an encrypted personal library to combine internal documentation with external search intelligence. Reports are synthesized with structured outlines, section headings, and verifiable academic citations that link directly to source references. Individual research sessions, system logs, and user credentials remain isolated in per-user SQLCipher databases protected by AES-256 encryption. Automated subscriptions deliver scheduled news digests and topic monitoring summaries directly to connected notification channels.

A single ejabberd node carries chat, device telemetry, voice calls, and federated messaging at once, because the same Erlang server speaks XMPP, MQTT, SIP, and Matrix over one authentication, storage, and clustering layer. Users get standards-based instant messaging with group chats, message archives, publish-subscribe, message carbons, push notifications, and OMEMO encryption, and your server federates with the global XMPP network out of the box. Devices publish and subscribe through the built-in MQTT broker on TCP or WebSocket transports, sharing accounts and access rules with your chat users instead of needing a second broker. Voice and video calls route through the integrated SIP gateway and STUN/TURN support, so WebRTC clients get signalling and media relay from the same deployment. Matrix support bridges federated rooms into the same infrastructure, letting two decentralised ecosystems interoperate without a separate bridge stack to babysit. Clustering with consistent hashing scales a deployment across nodes, and a single node is rated at two million concurrent sessions for very large communities. Operators manage everything from the web admin and command line, with SQL or Mnesia storage, LDAP authentication, and virtual hosting for multiple domains on one server.

Why rent your messaging from a corporate walled garden when Tinode runs WhatsApp-style chats, groups, channels, and calls on a server you control? Teams get one-on-one and group chats that stay in sync across web, Android, and iOS, with typing indicators, delivery and read receipts, presence, replies, forwarding, editing, pinned messages, and notes to self. Communities broadcast through read-only channels with an unlimited number of subscribers, and granular permissions decide who can read, write, or invite on each topic. Support desks welcome anonymous visitors, mark staff and verified accounts with badges, and put chatbots to work with forms and templated replies. Messages take markdown-style formatting, inline images and videos, file attachments, and voice messages. One-to-one voice and video calls run peer to peer over WebRTC, using the TURN and STUN servers you configure. Administrators block unwanted contacts on the server, attach moderation plugins over gRPC, and script the rest with a command-line tool. Attachments can sit on local disk or Amazon S3, the database can be MySQL, PostgreSQL, or MongoDB, and sharded clustering with failover scales past one server. The clients offer light, dark, and system themes, custom chat wallpapers, and translations for more than a dozen languages.

For people who found del.icio.us perfect and everything since bloated, linkding is the bookmark manager - a Django application whose entire design goal is saving and finding links with zero friction. Paste a URL and it fetches the title, description, favicon, and preview image automatically; organize with tags, search full-text across everything, mark bookmarks unread for read-it-later, attach Markdown notes, and bulk-edit whole selections at once. Its answer to link rot is archiving: bookmarked pages can be snapshotted automatically, either submitted to the Internet Archive or saved as local HTML files, and a documented SingleFile browser-extension integration uploads full self-contained page captures straight to your instance. Official Firefox and Chrome extensions (plus a bookmarklet) make saving a one-click habit, the UI installs as a Progressive Web App on mobile, and multi-user support with bookmark sharing - to users or logged-out guests - covers families and teams, with SSO via OIDC when needed. The REST API (create, search, filter by tag) has spawned a genuine ecosystem of community mobile apps and libraries. Operationally it is famously boring in the best way: one small container, SQLite by default, automated migrations, and a zero-breaking-changes policy. Import and export use standard Netscape HTML.

HomeGallery turns the photo and video folders on your server into a mobile-friendly web gallery. Your files and folder structure stay exactly as they are. Point it at camera files, phone files, or offline drives, and previews and metadata are extracted once. Scroll one endless stream, newest first. Open any image for its file name, dimensions, capture date, source paths, camera settings, street address, tags, and detected objects. Swipe between photos, then pinch or double-tap to zoom. The Map view clusters photos by place, with counts. The plant button lists similar images, so one sunset finds every other sunset. Face search finds the same person in other photos. A search box accepts expressions like tags in (vacation, family), type:video year in [2015:2020] order by duration, or not exists(geo). In Edit mode, select many photos at once and type comma-separated tags; a minus prefix removes one. Videos are transcoded for playback. Renamed or moved files keep their previews. An archive disk can stay unplugged once indexing is done. Optional logins limit each user to a query filter. Install it as a PWA for a lightweight mobile app. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Creative teams use Shumai to review video, images, 3D models, and documents with feedback pinned to the exact frame, on a server they control instead of a rented review cloud. Pause on any frame, draw on the picture, and leave a timecoded comment with the markup attached, then let threaded replies, mentions, and resolve states carry it to a decision. Every cut stacks into a version stack, and any two versions open side by side to compare changes. Layered PSDs and camera RAW review at full resolution, 3D models spin with comments pinned to the viewing angle, and documents page through as converted PDFs. Clients open a share link with a password and expiry date, downloads switchable, and can comment as guests with no account. Watermarks render into the media on your server rather than layering in the browser, so they stay put wherever the file travels. Comments export as Premiere Pro XML, DaVinci Resolve EDL, Final Cut Pro, or Avid files with correct drop-frame timecode for the editor. Mention the AI agent in a comment and it examines the same frame under discussion, or chat privately about a folder using your own OpenAI, Anthropic, or Gemini key. Originals live on local disk or any S3-compatible bucket, with GPU transcoding and workers that scale up for a delivery and back to zero.

Moodle gives teachers a place to build courses and learners a place to work through them, with quizzes, assignments, grading, and progress tracking on a learning platform you host yourself. Custom or weekly sections sit beside a course index, and Previous and Next buttons walk learners through activities in order. The activity chooser adds forums, wikis, glossaries, lessons, H5P content, and SCORM packages. Question banks can be shared across courses and track every edit, and quizzes combine calculated, ordering, and essay questions with due dates and Safe Exam Browser settings. Assignments offer in-browser PDF annotation, rubrics, and marking guides, and with a marking workflow several markers can leave separate feedback before grades are released. Peer assessment runs through workshops, competency frameworks feed learning plans, and Open Badges recognize achievement. With learning outcomes enabled, a course page lists each outcome beside the activities linked to it. Learners follow deadlines on a dashboard timeline, message classmates, and take course content offline in the official mobile app. Sign-in works through email self-registration, LDAP, Shibboleth, OAuth 2, or LTI, and enrollment through keys, cohorts, flat files, or PayPal. Administrators assign roles, build custom reports, and upload plugin ZIP files. AI actions can run on providers including OpenAI, Azure AI, Gemini, Ollama, and Anthropic Claude, and a course-level report shows how students use them.

Edict is a multi-agent orchestrator that runs every AI request through a court-style chain: a crown prince agent triages it, a planning department drafts the work, a review department can veto the plan, and specialist ministries execute what survives. Casual chat gets a direct reply, while real commands become kanban tickets whose titles are scrubbed of file paths and metadata. A vetoed plan returns for rework; an approved one is dispatched in parallel to ministries for finance, documentation, engineering, compliance, infrastructure, and HR. Commands arrive through Feishu, Telegram, or Signal channels configured in OpenClaw. The dashboard shows cards by state with heartbeat badges and stop, cancel, and resume controls, plus a department monitor and a memorial archive that turns finished work into five-phase timelines you can copy as Markdown. Nine edict templates add parameter forms and cost estimates, an officials panel ranks agents by merit score while tracking token spend, and per-agent model switching restarts the gateway in about five seconds. Agent thinking, tool calls, and results stream live. A permission matrix limits who may message whom, illegal state jumps are rejected, and every transition lands in an audit log. Worked examples cover competitive analysis, code review, and weekly reports. Dashboard login protects the console, and a systemd unit keeps it running across reboots.

Unpatched Linux servers expose production environments to critical vulnerabilities, and PatchMon eliminates that blind spot by centralizing package telemetry, security advisory tracking, and automated update orchestration across your entire fleet. Administrators can inspect pending updates across APT, DNF, YUM, APK, Pacman, Zypper, FreeBSD pkg, Windows Update, and winget from one unified queue without opening inbound firewall ports on monitored hosts. Before touching production workloads, operators run dry-run validations to preview exact package transactions, enforce multi-user approval workflows, and schedule rollouts during fixed maintenance windows. During execution, live agent output streams directly to the browser over WebSocket so engineers can watch progress in real time or halt a problematic upgrade mid-flight. Beyond package updates, the platform runs OpenSCAP CIS benchmark and Docker Bench security assessments, inventories running containers and outdated base images, and routes host-down or threshold alerts to Slack, Discord, Microsoft Teams, ntfy, or email. Built-in browser SSH and Apache Guacamole RDP terminals let teams troubleshoot machines directly through the outbound agent tunnel with role-based access control and OIDC single sign-on.

Ever Works transforms a single text prompt into a fully researched, written, coded, and deployed website through autonomous AI agents that operate on a configurable 15-step generation pipeline. Unlike one-shot builders, it continuously improves generated content on a schedule, keeping sites fresh without manual intervention. The platform integrates with six AI providers (OpenAI, Anthropic, Google, Groq, Mistral, Ollama) via gateways like OpenRouter and Vercel AI Gateway, while its plugin system connects ten search providers including Tavily, Brave, Exa, SerpAPI, and Perplexity for deep autonomous research. Every generation is Git-native — code and content live in your own GitHub repositories as commits, providing full version control, portability, and zero vendor lock-in. The monorepo ships a NestJS 11 REST API with JWT authentication, a Next.js 16 web dashboard for managing works, a CLI for terminal operations, an MCP server for AI agent integration, and admin tooling. Content management supports items, categories, tags, and collections, while deployment targets include Vercel and Kubernetes. Background processing runs on Trigger.dev with BullMQ scheduling, and monitoring leverages Sentry plus PostHog for error tracking and product analytics. The platform supports OAuth via GitHub and Google, subscription billing, email notifications, and AI chat conversations for natural-language interaction with your generated works.

SurveyKing combines survey creation and online examination in a single platform — generate complete questionnaires from plain English via built-in LLM integration, administer timed exams with anti-cheating proctoring, and collect structured data through 20+ question types including matrix questions, cascading selectors, file uploads, and electronic signatures. Built on Spring Boot 3 with a React and TypeScript frontend using the UMI framework and Ant Design components, version 1.12 delivers each question type with independent validation rules, data type controls, and formula calculations. The AI engine connects to mainstream LLMs for survey generation from natural language prompts and provides real-time answer explanations during practice sessions. Exam mode features item banks with Word and Excel bulk import, fixed and randomized question selection, composite paper assembly, live proctoring dashboards with anti-cheating controls, automatic and manual grading with per-question scoring, and PDF score report archiving. The visual logic designer and DSL expression engine handle show/hide conditions, required rules, skip branching, quota controls, randomization, and cross-tabulation analysis with SPSS export. Role-based access controls support multi-user collaboration with department and permission management via Spring Security and JWT authentication. Redis handles caching and queuing while MyBatis Plus manages database operations. Deploy via a single Docker command with embedded H2 for trials or Docker Compose with MySQL for production.

Manga collections tend to get trapped on a single phone; Suwayomi moves the library, downloads, and reading progress onto a server you run, so every browser and device sees the same shelf. In the browser, a built-in reader handles single page, double page, continuous vertical, continuous horizontal, and webtoon layouts, adding image filters, custom keybinds, auto scrolling, and separate desktop and mobile views. Content comes from Mihon (Tachiyomi) extensions, which can be searched, browsed, and sorted into categories, with custom extension stores loaded from JSON or Protobuf indexes. Downloads save chapters as CBZ archives for offline reading, and the server checks the library for new chapters every 12 hours by default, fetching them automatically if you allow it. Progress follows you through MyAnimeList, AniList, and MangaUpdates, a Suwayomi extension and tracker for Mihon, SyncYomi servers, and KOReader. E-reader apps connect over OPDS feeds, scheduled Mihon-compatible backups protect the library, and FlareSolverr or Byparr support handles Cloudflare-protected sources. Public instances can be locked down with basic authentication, a simple login page, or JWT-based UI login, and a PostgreSQL backend, still in beta, can replace the default file store.

With over 36,000 GitHub stars and adoption by organizations including Adobe, Shopify, and Roblox, HashiCorp Vault is the industry-standard platform for secrets management, encryption services, and privileged access control across hybrid and multi-cloud infrastructure. The key/value secrets engine stores arbitrary secrets with full versioning, soft-delete, and metadata tracking, while dynamic secrets engines generate on-demand, short-lived credentials for AWS, Azure, GCP, databases including PostgreSQL, MySQL, MongoDB, and MSSQL, and SSH access with automatic revocation after configurable lease periods. The PKI secrets engine dynamically issues X.509 certificates on demand with automatic rotation and ACME protocol support, eliminating manual certificate management workflows entirely. Encryption as a service through the transit secrets engine lets applications encrypt, decrypt, sign, verify, and generate HMACs without managing cryptographic keys directly, supporting AES-GCM-256, ChaCha20-Poly1305, RSA-2048/4096, ECDSA-P256/P384, and ED25519 algorithms. Authentication integrates with LDAP, OIDC/OAuth2, SAML, AppRole for machine-to-machine access, Kubernetes service accounts, AWS IAM, Azure Active Directory, and GitHub tokens. Fine-grained ACL policies use path-based rules with glob patterns and sentinel policies for programmatic enforcement. The integrated Raft storage backend provides high-availability clustering without external dependencies, while alternative backends include Consul, S3, DynamoDB, PostgreSQL, and MySQL. The built-in web UI provides a visual interface for browsing secrets, managing policies, configuring auth methods, and monitoring cluster health.

CRMs, project trackers, inventory tools - NocoBase is an open-source no-code/low-code platform for building business systems like these. Its architecture is data-model driven: you define collections and relationships first, then compose any number of interface blocks (tables, forms, kanban, charts) on top of the same model, so data structure is never coupled to a particular view. The core is a microkernel where every feature is a plugin, WordPress-style; you enable official plugins, install marketplace ones, or write your own as npm packages with server and client parts. Data sources include the main PostgreSQL or MySQL database, external databases, and third-party APIs - so you can build admin panels over existing production data instead of migrating it. Built-in infrastructure covers role-based permissions down to collection, record, and field level, workflow automation with approval steps and scheduled triggers, and audit logs; a one-click switch flips between usage and configuration modes. Because custom features live in isolated plugins with a documented lifecycle, core upgrades do not overwrite your customizations, and swapping UIs never requires data migrations since interfaces sit on independent models. Written in TypeScript on Node.js, Koa, and React under the AGPL license, it is light enough for one person to run and extend - and where no-code SaaS platforms charge per seat and per app, a self-hosted instance runs unlimited applications for unlimited users at hosting cost alone.

An agent run can finish without errors and still give the wrong answer, so TraceRoot traces every model and tool call, flags the production runs that missed the mark, and helps your coding agent ship verified fixes. Each run becomes a browsable call tree with inputs, outputs, latency, and cost, searchable by session or filter. Instrument with the Python or TypeScript SDK, the agent-native CLI, or any OpenTelemetry exporter, with ready integrations for LangChain, LangGraph, OpenAI Agents SDK, CrewAI, Vercel AI SDK, Mastra, and Pydantic AI. Detectors use LLM judges to score live traffic against the behavior you define and can post alerts to Slack. Judge outputs cluster into signals, then a background coding agent reads the traces and your connected GitHub code in a sandbox and recommends changes down to the commit, file, and line. Datasets, test cases, and scored eval runs compare versions so regressions surface before a release, and dashboards of widgets chart your trace data. The CLI hands your coding agent, such as Claude Code or Codex, the traces, signals, detectors, and evals to work from. Self-hosting keeps all of that trace data on infrastructure you control.

Krayin CRM gives sales teams a visual Kanban pipeline where leads flow through configurable stages — new, contacted, qualified, proposal, won, lost — with deal values tracked per stage, drag-and-drop transitions, and AI-powered document import that extracts contact details from uploaded PDFs, DOCs, and images without manual data entry. Built on Laravel 12 with a Vue.js frontend and MySQL database, the platform delivers complete customer lifecycle management through a two-stage contact model separating unqualified Leads from qualified Persons linked to Organizations, with a unified timeline displaying associated activities, notes, emails, and deals. The activity module schedules calls, meetings, and tasks on a drag-and-drop calendar with reminders and team assignment. A built-in product catalog supports line-item quoting with pricing and quantities. Email integration connects via SMTP, IMAP, and SendGrid parsing, linked to leads and contacts automatically. Workflow automation triggers actions on conditions and pushes events to external systems via webhooks. The dashboard visualizes pipeline performance, top customers, top products, and email engagement with pie charts and trend widgets. Custom attributes add text, number, date, boolean, and dropdown fields to any entity. Role-based ACLs manage team permissions per module. Extensions add multi-tenant SaaS, WhatsApp lead generation, and VoIP calling. Deploy via Docker Compose.

Command and automate your entire fleet of 3D printers without relying on proprietary cloud services using Bambuddy, a self-hosted management hub that delivers local network control, print scheduling, and job archiving for Bambu Lab hardware. Print shop operators can route slicing output directly from Bambu Studio or Orca Slicer through virtual printer proxies that emulate physical machines while automatically cataloging print files in a searchable 3D repository. The automated dispatch engine assigns queued gcode files to available printers based on required nozzle temperatures, build plate dimensions, and matched multi-color filament slots. Users can inspect live camera streams across multiple printing beds simultaneously, verify empty build plates before dispatching new jobs, and generate stabilized timelapse videos with custom music. Integrated smart plug connectors automatically cut power to idle machines when print cycles finish and trigger push notifications to Discord or mobile devices if thermal anomalies or mechanical pauses occur. Farm managers can schedule maintenance alerts based on cumulative motor runtime, track spool inventory levels across storage locations, and synchronize printing configurations across duplicate hardware setups.
