FalkorDB is the first queryable property graph database to leverage sparse adjacency matrices and linear algebra for graph traversal, replacing traditional pointer-chasing with GraphBLAS-accelerated computation. Originally the RedisGraph engine, it was relaunched as FalkorDB in 2023 and rewritten from C to Rust in 2026 for improved memory safety and performance. The database supports the OpenCypher query language with proprietary extensions, translating queries into linear algebra expressions that exploit AVX hardware acceleration. Indexing options include full-text search, vector similarity for embedding-based retrieval, and range indexing, while connectivity supports both the RESP protocol for Redis clients and the Bolt protocol for Neo4j-compatible tooling. The GraphRAG SDK enables ingestion of documents in text, PDF, and Markdown formats into knowledge graphs, with schema-guided entity extraction, hybrid retrieval combining vector and graph traversal, relationship expansion, and cited answers for LLM applications. Official client libraries cover Python, Node.js, Java, Rust, Go, PHP, and C#. Multi-tenant support handles over 10,000 concurrent graphs with zero overhead and full isolation. Docker deployment runs the falkordb/falkordb image on ports 6379 for the database server and 3000 for the built-in browser UI, with persistent volume storage and optional authentication. A production falkordb-server image excludes the browser for lighter deployments. On RepoCloud, deploy FalkorDB on a dedicated VPS with root SSH access, persistent storage for your graph data, and complete control over authentication, thread count, and memory configuration, all under the SSPLv1 license.

ENZO is a self-hosted AI workspace where you bring your own provider API keys and chat with more than 300 models from nine providers in one streaming interface with normal, thinking, research, and coding modes. You describe an agent in plain English and a two-pass builder drafts its full operating manual, picks the tools the task needs, and keeps improving from your activity through a per-agent neural layer you can inspect. Seventy-four bundled skills give agents ready-made domain playbooks, and a skill editor lets you write your own. Agents can read Gmail, check Calendar, search the web, and run a deep-research loop that writes its own queries under hard budgets so it cannot burn your key. Coding mode writes a multi-file project, boots it, and previews it live while telling you when something is broken. A unified model marketplace compares providers with live health checks, download counts, and benchmarks, and a built-in music player streams songs with a five-band equalizer. Your keys stay sealed in a passphrase-encrypted browser vault and travel only to the provider you picked, so there is no ENZO account, usage meter, or subscription taking a cut.

Turning a plain server into your own Heroku is what HivePaaS does: deploy apps from Git or Docker images, attach domains with automatic certificates, and manage everything from one dashboard. Push a repository and it builds with your Dockerfile, or generates one for more than 15 languages and frameworks, with deploy on push and pull request previews for review. Write functions in Node.js, TypeScript, Bun, Python, PHP, or Go and run them over HTTP or on a schedule without standing up separate services. Install databases, content systems, analytics, monitoring, and automation from an app store of more than 300 one-click templates. Give managed Postgres and MariaDB automatic backups, scheduled restores, and point in time recovery, and route traffic with redirects, basic auth, and IP or rate limits per app. Watch live logs, open a terminal inside containers, follow CPU and memory metrics, and scan running images for vulnerabilities with fixable findings first. Back up apps encrypted to S3 compatible storage, clone or export them, organize projects and environments with role based access and two factor authentication, and scale across multi node clusters with autoscaling and scheduled jobs. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Publish the answers your team keeps repeating as a multilingual, searchable FAQ with phpMyFAQ, a knowledge base whose admin area handles writing, review, and permissions. Organize entries in nested categories that you rearrange by drag and drop, attach files, add tags and related FAQs, and let visitors leave comments. A WYSIWYG editor with an image manager writes each answer, a wiki-style revision history restores earlier versions, and a news system posts announcements. Full-text search covers every language, and optional Elasticsearch or OpenSearch backends handle larger collections. The interface covers more than 40 languages with right-to-left layouts, automatic content negotiation, and translated categories and entries. Privileges work per user and per group, so an editor can change an entry without being allowed to delete it, and categories can be limited to chosen readers. Sign in through LDAP, Active Directory, or Microsoft Entra ID, protect accounts with two-factor authentication, or try experimental passkeys. The dashboard charts 30 days of visits, lists inactive FAQs, and checks installed files against published hashes. Export entries to PDF, publish a dynamic sitemap, back up your content, and filter spam with built-in protections. Dark, light, and high-contrast themes keep the public site comfortable to read. Scripts and AI assistants reach the knowledge base through a REST API with an OpenAPI specification or an experimental MCP server, and plugins extend it.

Tududi is a self-hosted planner that turns a pile of tasks into a plan for the day, keeping projects, notes, goals, and habits on a server you control. One Add box files an Inbox item, Task, Note, or Project and understands natural-language dates, recurrence, tags, projects, and people, so "every first monday #home" becomes a recurring task without opening a form. The Today page switches between planning mode, with a timeline or list beside your calendar and optional AI help to sketch the day, and doing mode, with a Next card and a hint when a free slot fits a small task. Tasks have subtasks and live in projects and areas, projects link to season or year goals, and saved views, project templates, and optional Eisenhower and Kanban boards organize the work. Habits support build or quit goals with streaks, a strength score, and a history grid, while notes offer linked pages, backlinks, and mermaid diagrams. Households and teams share projects with read-only or read-write access, assign tasks to people, and follow an Everyone board; members without email sign in through one-time links. Telegram captures tasks and can send daily summaries, CalDAV syncs with reminder apps, OIDC handles single sign-on, and an MCP server lets Claude or Cursor manage tasks. AI stays off until you enable it and add a provider; local models work too.

Name a game and Romarr goes and finds a copy you can prove is good. Search every indexer at once, through Prowlarr or directly, and each release comes back scored with the reasons written out: seeders, the right region, a plausible size, points off for hacks, betas, and repacks. The winner goes to whichever client speaks its protocol, from thirteen torrent daemons and eight debrid services to SABnzbd or a plain watched folder, and within a minute of finishing, the ROM itself is picked out of its archive, multi-track discs kept together as a set. Then comes the part no other library manager does: every import is checksummed against your No-Intro and Redump DATs and stamped verified, bad dump, or unknown. A verified dump is byte-for-byte the published one, a bad dump is refused unless you force it, and homebrew or translations import without ceremony as unknown. A verified copy automatically upgrades an unverified one, collections compare against a DAT to show exactly what you are missing, and duplicates are audited before anything moves. Finished games land in RomM, Gaseous, Retrom, or a simple folder, routed per platform, and your library server is told to rescan so the game appears with its art.

Simon is a lightweight self-hosted system monitor that shows live CPU, memory, disk, and network metrics for your server and its Docker containers in one web dashboard, with threshold alerts and a built-in file browser. Open the dashboard to watch real-time gauges alongside historical charts, so a slow memory leak becomes visible hours before it takes a service down. Every running container appears with its own CPU and memory stats, and its logs open in a searchable viewer, so routine diagnosis never needs a terminal session on the host. The file browser lets you navigate the directories you choose to expose, preview file contents, upload with drag and drop, create folders, and move or delete items. Downloads support range requests, which means large files resume cleanly after a dropped connection and media files stream instead of failing halfway. Alert rules fire when CPU, memory, disk, or network activity crosses thresholds you set, and notifications arrive through Telegram, ntfy, Gotify, Pushover, Pushbullet, Matrix, or any custom webhook. Prebuilt notification templates get common setups running in minutes, and password authentication keeps the dashboard private on a public server. Resource-constrained machines benefit most: the monitor runs comfortably on single-board computers and small instances where heavier monitoring stacks would consume the very memory they exist to watch.

Upload a report, ask a "what if" question in plain language, and MiroFish builds a small simulated society that plays out the answer before you commit to a decision. It reads your seed documents, whether news, policy drafts, financial signals, or a novel, and extracts entities and relationships into a GraphRAG knowledge graph. Entities from the graph become agents with a profession, a biography, and interest tags, and the app estimates simulation rounds from the simulated time span, with a custom mode for shorter runs. Agents post and react on two simulated platforms at once, a feed-style plaza and a topic community, while a live monitor tracks rounds, elapsed simulated time, and actions. A ReportAgent then plans an outline and writes the prediction report section by section with the InsightForge, PanoramaSearch, QuickSearch, and InterviewSubAgent tools. Afterward you can keep questioning the ReportAgent, chat with any individual agent, or send a survey question to a selected group and read their answers. Typical uses include rehearsing public relations responses, testing policy drafts against likely reactions, and exploring alternate endings for a story. The interface switches between English and Chinese, and you bring your own model: any OpenAI SDK compatible LLM endpoint works, Zep Cloud stores agent memory, and the project suggests starting under 40 rounds because runs consume many tokens.

A personal to-do list that scales to team project management: Vikunja is an open-source task manager that grows with the work. Every project can be viewed four ways - classic list, drag-and-drop Kanban board, Gantt chart for timeline planning, and a spreadsheet-style table - so a project manager watches the Gantt while developers work the board, on the same data. Tasks carry the full attribute set: labels, priorities, due dates and reminders, recurring schedules, subtasks and task relations, file attachments, assignees, and comments, and Quick Add Magic parses natural-language input like dates and labels typed inline. Projects share with team members or via links, and saved filters slice tasks across projects. Built-in CalDAV support (VTODO) syncs tasks bidirectionally with clients like Thunderbird, DAVx5, and iOS Reminders, and one-click importers migrate from Todoist, Trello, and Microsoft To-Do. Nothing is metered - unlimited projects, tasks, filters, and attachments. A single Go binary with a Vue frontend runs against SQLite, MySQL, or PostgreSQL, exposes a full REST API, and works as an installable PWA on mobile. AGPLv3-licensed.

Homeio turns a Linux box into a desktop you open in a browser tab, with draggable windows, a dock, a lock screen, and a command palette sitting on top of your Docker apps, files, and disks. The App Store installs Docker Compose stacks from the CasaOS catalog or your own store sources, and each app's ports, volumes, environment variables, and compose file stay editable before and after install. Containers you started elsewhere still appear with live CPU and memory stats, streaming logs with keyword filters, and one-click restarts. The file manager uploads with progress, previews images, audio, video, and PDFs, edits text in a built-in code editor, mounts USB drives and SMB shares, and shares folders over Samba. A real login shell lives in the Terminal window, with exec access into any container, so routine fixes never need a separate SSH client. Cron-style scheduled tasks restart apps, pull images, or run backups on a timer, and scheduled archives of the database, files, and compose stacks restore from the same interface. Tailscale puts the whole desktop on your private network, while Cloudflare Tunnel can publish a single app on a public hostname with its DNS record created for you. Live metrics stream to widgets and the status bar, and notifications flag crashed containers, filling disks, and failed tasks.

Transforming fragmented research notes, daily technical logs, and project documentation into an interconnected knowledge base is what NoteDiscovery delivers for privacy-conscious teams and researchers. Writers compose rich documents using a dual-pane editor that renders MathJax equations, interactive task lists, and dynamic Mermaid sequence diagrams side by side with raw text. The interactive knowledge graph maps semantic relationships across notebooks, allowing researchers to explore backlinks, uncover hidden topical connections, and navigate complex idea webs visually. Team members sketch architecture diagrams and wireframes directly inside note canvases using the integrated drawing tool, saving revisions as embedded image layers without external editors. The platform organizes thoughts through flexible tag hierarchies, nested folder trees, and reusable document templates equipped with automatic date and variable substitutions. Autonomous coding assistants and language models query documentation, create structured meeting summaries, and update project indexes directly through the native Model Context Protocol server. Built-in export tools convert notebook collections into standalone HTML packages, printable documents, or portable Markdown archives for offline archiving.

PdfDing turns a scattered folder of PDFs into a proper library you can read, annotate, sign, and share from any browser. The viewer remembers exactly where you stopped in every document, so a manual opened on your desktop resumes mid-page on your phone, and progress bars in the library show how far you have read at a glance. Workspaces and collections group related documents, multi-level tags classify them, and starring, archiving, and bulk actions keep even a large archive tidy. Inside the viewer you can add text, highlights, and freehand drawings, then review and export your highlights and comments from dedicated sections and attach Markdown notes to a document. A signature you create once is stored on your server and waits for you on every device, ready to drop onto contracts and forms. Sharing a collection or a single PDF takes a link or a QR code, with optional access control over who can open it and for how long. Accounts are protected by OIDC single sign-on and two-factor authentication with TOTP or WebAuthn, and dark mode, an inverted color mode, and multiple layouts keep long reading sessions comfortable.

Some messages should only arrive if you cannot send them yourself, and Aeterna is a self-hosted dead man's switch that makes sure they do. You write the messages, attach the files that matter, name the people who should receive them, and check in on a rhythm you choose. Keep checking in and nothing happens. Stop, and Aeterna delivers what you left behind. Each switch pairs your words with documents, photos, or instructions for specific recipients, and switches can address multiple recipients so one message can reach a partner, a sibling, and a lawyer at the same time. File attachments are stored encrypted and are automatically deleted from the server right after delivery, so sensitive material does not linger once it has done its job. Check-ins take seconds through the web interface or a quick link in your email, which keeps the heartbeat habit painless. When a switch fires it can also call webhooks, triggering home automation or custom scripts alongside the emails. Your SMTP settings live in the settings screen with live testing, and reverse proxy templates for Nginx, Traefik, and Caddy help you put the service behind your own domain with proper certificates.

Viewers arrive on browsers, phones, and desktop players, and SRS meets each of them with the right protocol from a single published stream. A broadcaster pushing RTMP can reach browser viewers through WebRTC with sub-second latency, phone apps through HLS, and desktop players through HTTP-FLV, all from the same live source without running parallel encoders. WHIP endpoints accept WebRTC ingest from browser studios and tools like OBS, while WHEP serves WebRTC playback, so an entire publish-to-viewer path can stay on modern web protocols. Operators shape each channel with virtual hosts, authenticate publishers and players through HTTP hooks that consult your own backend, and record live streams to disk as DVR archives for replay. Forwarding republishes a stream to YouTube, Facebook, or another SRS instance, and origin clustering lets edge servers pull from a central origin so one ingest feeds viewers in several regions. The built-in HTTP API reports streams, clients, and server health for monitoring, and GB28181 support ingests surveillance camera networks alongside creator broadcasts. Configuration lives in a single reloadable file, so changing a vhost or enabling HLS rarely means restarting the listeners your audience is attached to.

Engineering teams and technical writers maintain operational runbooks, system documentation, and knowledge bases using LeafWiki, an open-source self-hosted wiki that stores page contents directly as human-readable Markdown files on the local filesystem. Authors can compose documentation through a dual-pane editor equipped with live HTML preview, keyboard navigation, autocomplete for internal links, and native rendering for Mermaid diagrams, KaTeX mathematical formulas, and collapsible callout containers. The navigational tree organizes complex documentation into explicit directory hierarchies and custom drag-and-drop page sequences tracked in lightweight configuration files rather than arbitrary alphabetical lists. An integrated SQLite engine indexes page content and custom taxonomy tags for fast full-text searches, automatic incoming backlink tracking, and automated broken link detection. System operators can deploy the single-binary application without external database servers or runtime dependencies, backing up the entire repository by copying the data directory. Administrators can provision granular user roles, configure reverse proxy header authentication for single sign-on gateways, and manage read-only API access keys for automated documentation scripts and continuous integration pipelines. Public viewers can browse technical notes without authentication or switch between dark and light high-contrast themes.

Google Workspace and Microsoft 365, replaced by a platform you actually control: Nextcloud is the self-hosted digital workspace. Files is the core: file storage and sync across desktop, mobile, and web clients, with sharing, versioning, and collaboration built in. Around it, Talk provides private text chat, audio/video conferencing with screen sharing, SIP integration, and persistent voice rooms; Groupware bundles calendar, contacts, and mail with delegation support; and Office offers two collaborative suites - the Collabora-based option with deep ODF support, and Euro-Office, whose local-processing architecture delivers strong Microsoft Office compatibility and fast browser rendering with reduced server load. The Nextcloud Assistant threads AI through the platform via a context-aware sidebar, Whiteboard covers visual collaboration, Flow handles automation, and an app ecosystem of hundreds of extensions adds everything from Kanban boards to end-to-end encryption. Hub 26 brings a lighter UI with a unified app switcher and Nextcloud Governance for organizations under strict regulatory requirements. This is the flagship of data sovereignty: your files, chats, calendars, and documents live on your server, under your jurisdiction, with GDPR compliance by architecture rather than by contract.

When an agent breaks production at 3 a.m., "the model did it" is no incident report: Bernstein decides in advance what your AI agents may touch, then keeps receipts proving what they did. You write policy as code: which roles may do what, what needs human approval, and what must be recorded before a task counts as done. A deterministic scheduler with no model in the coordination loop turns each goal into parallel tasks, so replaying yesterday's plan reproduces yesterday's task graph exactly. Every coding task runs in its own git worktree behind merge gates; nothing lands on your main branch until tests, lint, and type checks pass. It drives the CLI agents you already use (Claude Code, Codex, Gemini CLI, Aider, Goose, dozens more), mixing cheap local models with heavy cloud ones in one run. Approvals can demand a hardware key touch, and role fences hold whatever an agent tries inside its task. The journal, lineage record, and optional tamper-evident audit chain capture every step, sealed into an Ed25519-signed receipt verifiable offline from the file alone. Non-code work gets the same treatment: an artifact contract names the deliverable (report, dataset, audit evidence pack), and the task completes on a signed receipt instead of a commit. You supervise from the browser dashboard or terminal UI, watching tasks, agents, approvals, and costs live.

Send a document, receive a PDF: Gotenberg is a Docker-based, stateless HTTP conversion API trusted in production by thousands of companies and adopted by notable open-source projects. Send files as multipart/form-data, get a PDF back; Chromium, LibreOffice, and fonts are the container's problem, not yours. Headless Chromium handles URLs, HTML templates, and Markdown with pixel-perfect browser rendering: it executes JavaScript, loads web fonts, waits for network idle, a JS expression, or a DOM selector before rendering SPAs, and accepts injected cookies and HTTP headers for authenticated pages. LibreOffice converts 100+ office formats - .docx, .xlsx, .pptx, and legacy formats - with page-range extraction and PDF/A archival conformance. Built-in PDF engines round out the pipeline in every image variant: merge, split, rotate, flatten, encrypt, watermark, stamp, read/write metadata and bookmarks, plus Factur-X/ZUGFeRD e-invoicing and PDF/UA accessibility compliance. Screenshots of URLs and HTML come from the same endpoints. Zero-transfer pipelines stream files directly between S3, MinIO, or GCS presigned URLs and Gotenberg, bypassing your application entirely, and webhooks enable async processing. Statelessness means horizontal scaling is trivial - run as many replicas as your conversion volume demands. Three image variants (full, Chromium-only, LibreOffice-only) trim the footprint to what you actually use.
