Sage Wiki turns a pile of unstructured documents into a fully interlinked, searchable wiki by running them through a five-pass LLM compiler pipeline. Inspired by Andrej Karpathy's vision of LLM-compiled knowledge bases, the pipeline processes source files through diff detection, summarization, concept extraction, image captioning, and cross-reference discovery, with parallel LLM calls and checkpoint/resume for vaults scaling to 100,000+ documents. The typed ontology graph stores entities and relations with BFS traversal, configurable relation types, multilingual synonyms, and a promotion/demotion lifecycle backed by grounding verification and consensus scoring. Multi-format ingestion handles Markdown, PDF, Word, Excel, PowerPoint, EPUB, email, CSV, images, and code files without manual tagging. LLM provider support spans Anthropic, OpenAI, Gemini, Ollama, and any OpenAI-compatible API, with per-pass model routing enabling cost optimization by assigning cheaper models to simpler tasks. The built-in MCP server exposes 17 tools over SSE transport for integration with Claude, Cursor, and any MCP-compatible agent, while native Obsidian vault overlay ensures existing note workflows remain undisrupted. Team deployment supports Git-synced shared wikis, centralized server access, and hub federation across multiple projects. Ships as a single Go binary with Docker Compose multi-arch images serving the web UI on port 3333. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Wiki-Go turns a folder of Markdown files into a searchable team wiki with page history, comments, and access rules, and never asks you to run a database. Pages live in a nested tree with a sidebar and breadcrumbs, and an editor with a preview toggle handles emoji shortcodes, highlighted code, LaTeX math, Mermaid diagrams, collapsible sections, GitHub-style alerts, and embedded YouTube, Vimeo, or MP4 video. Full-text search supports exact phrases in quotes and term inclusion or exclusion, and highlights each match. Each save keeps a revision, up to a configurable limit, and any stored version can be restored later. Attachments such as PDFs, spreadsheets, images, and archives sit beside the page they belong to. Drop a Kanban board into any document for drag-and-drop task tracking with nested tasks, or build a categorized link library that fills in page metadata automatically. Signed-in users comment in Markdown, and admins can remove comments. Admin, editor, and viewer roles, user groups, path-based public or private rules, and an optional private-wiki mode decide who sees what. Branding comes from a custom logo, banner, and favicon, shortcodes such as stats insert live site statistics, and readers can switch between dark and light themes or print any page. A REST API opens content to scripts, and a community tool imports Notion exports. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

TriliumNext organizes notes in an infinitely deep tree where any single note can be cloned into multiple branches without duplication, building personal knowledge bases that mirror how ideas actually connect rather than forcing a single rigid folder hierarchy. Carrying forward the original Trilium project under active community stewardship with nearly 37,000 GitHub stars, the application is built on TypeScript with a CKEditor 5 WYSIWYG editor supporting rich text, tables, images, KaTeX math expressions, Mermaid diagrams, Excalidraw canvases, mind maps, spreadsheets with XLSX and CSV import/export, and code blocks with full syntax highlighting. A built-in JavaScript scripting engine runs on both frontend and backend, enabling custom widgets, automated workflows, scheduled tasks, and direct interaction with external REST services through a typed Script API. Full-text and fuzzy search with attribute-based queries locates any note instantly across databases tested at over 100,000 notes without performance degradation. The v0.104 release introduced importers for OneNote, Notion, Google Keep, Anytype, and Obsidian alongside 16 dedicated security fixes. Per-note AES encryption, OpenID Connect authentication, and TOTP two-factor protection safeguard sensitive content. The sync server keeps desktop clients, the progressive web app, and mobile devices in lockstep with zero third-party cloud dependency. Web Clipper captures content directly from browsers. 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.

Enterprise documentation discipline without enterprise infrastructure: Documize Community is the Confluence alternative built on exactly that trade. The entire platform - Go backend, Ember.js frontend - compiles to a single executable binary for Linux, Windows, and macOS with zero runtime dependencies: no Elasticsearch, no Redis, no JVM. Point it at PostgreSQL, MySQL, MariaDB, Percona, or Microsoft SQL Server (rare in open source, decisive in Microsoft shops), and schema migrations run on launch with native full-text search on whichever engine you chose. Content organization rejects nested-folder sprawl for Spaces, categories, and labels, and the section-based composable editor mixes rich text, Markdown, code blocks, PDFs, diagrams, and embedded Jira or Trello content in one document, with reusable blocks and templates so teams start from standards rather than blank pages. It deliberately unifies internal team docs and customer-facing documentation in one system with granular space-, document-, and action-level permissions deciding who sees what. Where wikis stop, Documize continues: content approval workflows (draft, review, approve, publish), version management, lifecycle control, feedback capture, PDF export, analytics showing what gets read and ignored, activity streams, and audit logs. Keycloak, LDAP, and SSO integrate for enterprise auth. AGPL-licensed.

Every wiki page lives as a plain-text file in a standard Git repository, giving you full version history, branching, merging, and the freedom to edit with any text editor or IDE alongside the web interface. Originally built by GitHub's founders as the engine behind GitHub's own wiki feature, Gollum supports Markdown, AsciiDoc, reStructuredText, Org-mode, Textile, MediaWiki, Creole, and Pod markup formats with live preview rendering as you type. PlantUML and Mermaid diagrams render inline for architecture documentation, MathJax handles mathematical notation, and BibTeX integration via Pandoc provides academic citation management. YAML frontmatter controls per-page sidebars, headers, footers, and table of contents generation. CriticMarkup annotations enable editorial review workflows with tracked insertions, deletions, substitutions, and comments. Macros extend pages with dynamic content injection, file includes, and navigation helpers. The wiki maintains compatibility with GitHub and GitLab wiki repositories, so teams can clone existing platform wikis for local editing and offline access. The official Docker image at gollumwiki/gollum exposes port 4567 with volume-mounted repositories, requiring roughly 170 MB of container storage and minimal RAM. Authentication integrates via OmniAuth supporting GitHub, GitLab, Google, and other OAuth providers. Over 14,300 stars on GitHub since 2009. MIT licensed.

Every page in a DokuWiki knowledge base is just a plain text file on disk, so a team wiki can run for years on modest hardware with no database to feed, ever. Writers edit pages in a clean, readable syntax, fix just one section of a long document at a time, and lean on the toolbar, breadcrumbs, automatic tables of contents, and conflict locking to keep collaboration painless. Every change is kept as a revision with colored side-by-side diffs, recent-changes feeds go out over RSS, and an index-based full-text search finds content across thousands of pages in milliseconds. Namespaces organize content into a browsable tree, while built-in access control lists decide per page or per branch who may read, edit, upload, or administer, with logins checked against LDAP and other backends. Media uploads embed straight into pages, configuration happens in the browser, and the whole installation backs up by copying a folder, which makes migrations and disaster recovery almost boringly simple. When the basics stop being enough, more than twelve hundred community plugins and a hundred templates add galleries, multilingual structures, diagrams, and data tables without changing how the wiki itself works.

OpenDeepWiki transforms code repositories from GitHub, GitLab, Gitee, Gitea, and AtomGit into structured, searchable knowledge bases by leveraging Microsoft's Semantic Kernel for AI orchestration across OpenAI, Azure OpenAI, Anthropic, and DeepSeek providers. The three-phase Gather-Think-Write pipeline analyzes repository tree structures, generates README summaries, project overviews, wiki catalogs, and document content while producing Mermaid mind maps and optional Graphify visualization artifacts. Repository-scoped MCP endpoints at /api/mcp/{owner}/{repo} expose indexed knowledge to external AI tools, while the built-in chat assistant, embedded chat APIs, and share links provide conversational access to repository understanding. The Next.js 16 frontend serves public documentation on SEO-friendly routes with multi-language translation support, and the admin console manages repositories, users, roles, API keys, AI provider and model configuration, skills, and GitHub App imports. Background workers handle incremental updates using LibGit2Sharp to keep documentation synchronized with evolving codebases, while Polly integration provides transient failure retry handling for LLM requests. The platform supports SQLite, PostgreSQL, and MySQL database backends with Entity Framework Core providers.

Every page in Otter Wiki is a plain Markdown file and every save is a git commit, so a small team gets a simple wiki whose history never goes missing. The editor highlights Markdown as you type, offers a toolbar for headings, lists, tables, code, alerts, and images, and can show a live preview beside the source. Paste or drop an image into the editor and it is stored as a page attachment. History, blame, and changelog views, with RSS and Atom feeds, show who changed what and when. Beyond standard Markdown you get footnotes, task lists, math formulas, Mermaid diagrams, alert boxes, and spoiler or folded blocks, plus experimental embeddings such as sortable data tables, info boxes, image frames, videos, and included pages. A customizable sidebar shows a menu, a page index, or both. Search offers case-sensitive and regular expression options. Dark mode is built in. Admins decide whether anonymous visitors, registered users, or approved users may read, write, or upload, grant rights per user, close registration, or require email confirmation. An optional, experimental git web server lets people clone, pull, and push the wiki, and changes can be pushed to or pulled from a remote repository over SSH. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

For people whose notes number in the tens of thousands, Trilium Notes is the hierarchical note-taking application built specifically for large personal knowledge bases - actively maintained as TriliumNext. Notes arrange into arbitrarily deep trees where every note is both content and container, and cloning lets a single note live in multiple places at once - bash notes belong under both Linux and Scripting, and Trilium refuses to make you choose. A WYSIWYG editor handles rich text, tables, math, and syntax-highlighted code blocks with Markdown-style shortcuts, while dedicated note types cover Excalidraw sketches, mind maps, geo maps with GPX tracks, relation maps that visualize connections between notes, and tables with typed columns. The attribute system is the power layer: labels attach queryable metadata (#year=1999, #author), relations create named links between notes, and both inherit down the tree - feeding full-text search, saved queries, and scripting. Scripting is Trilium's deepest differentiator: JavaScript code notes run on events like note changes or hourly schedules, build custom widgets, and add server-side logic, turning the knowledge base into a programmable platform. Protected notes encrypt sensitive content, note hoisting focuses on subtrees, and the self-hosted server syncs desktop clients across devices.

Think of Storyden as running your own small Reddit, except the knowledge your community produces does not scroll away and die in the feed. Discussion happens in threaded forums organized by categories and tags, where posts collect replies, likes, emoji reactions, and saves into personal collections. Beside the chatter sits the Library, a tree of rich pages your members build together into wikis, directories, catalogs, and guides that stay findable. Library pages carry typed properties, attached files, and table views, so a car club can track vehicles as data instead of arguing over a spreadsheet. Threads can reference Library pages and pages can link back to threads, letting a great answer graduate into permanent knowledge. Optional AI assistance helps organize titles, tags, and summaries, while the recommendation engine surfaces posts each member is likely to care about. The first account registered becomes admin, roles and permissions govern who can post or moderate, and community settings live in the admin panel rather than config files. One container starts everything with an embedded database and local file storage, and OpenAPI documentation is served from the same address.

The entire wiki - content, code, and interface - is built from "tiddlers," small addressable units of information that link, transclude, tag, and filter into each other: TiddlyWiki is a non-linear personal notebook with a design philosophy unlike anything else in this catalog. Instead of pages in a hierarchy, you compose views by pulling tiddlers together on demand, which is why researchers, zettelkasten practitioners, and GTD devotees have sworn by it for two decades. The whole application is JavaScript, and the UI itself is written in hackable WikiText - customization goes as deep as rewriting the interface from inside the wiki. Self-hosting runs the Node.js version, which upgrades the classic single-HTML-file architecture in the ways that matter for a server: every tiddler is stored as an individual text file (Git-friendly, organizable), edits save through the HTTP API from any modern browser including phones, and one installation can serve multiple wikis blending shared and unique content. The plugin ecosystem covers graph visualizations, themes, languages, and hundreds of community extensions, declared per-wiki in a simple tiddlywiki.info file; the newer MultiWikiServer plugin adds multi-user accounts and tiddler sharing. Your notes stay usable for decades, independent of any corporation - the project's founding promise. BSD-licensed.

Hatchdoor gives your Markdown notes two front doors at once: a fast web interface for you, and an MCP endpoint where AI agents read and edit the very same vault. Point it at any folder of Markdown files, an existing Obsidian vault included, and it indexes everything into a disposable SQLite read model that rebuilds itself from your files if deleted. In the browser you browse folders, follow wikilinks that survive renames, explore backlinks and graph views, and search by keyword or meaning across every vault you mount. The live editor shows Markdown syntax only on the line you are editing and saves automatically, while concurrency checks refuse a save when the note changed underneath you. Agents connect with their own token and start read-only; turn writes on and Claude Code, Codex, Cursor, or Hermes can create, edit, move, and link notes through the same checked operations the interface uses. Saved queries in Obsidian's Bases syntax render as live tables, attachments preview inline, and optional git integration commits and pushes every change back to your vault's repository. 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.

Write your knowledge as plain Markdown files, and WikiDocs turns the folder into a searchable, versioned wiki with no database to set up or back up. Pages carry YAML front matter, so the whole wiki can be copied, archived, or opened in any text editor. An editor with a formatting toolbar handles headings, lists, task lists, links, and images, and pictures can be pasted straight from the clipboard. Math is typeset with KaTeX, Mermaid renders diagrams such as ER models and mind maps, and code blocks get syntax highlighting. Every save keeps a revision, a versions dialog lists them, and deleted pages wait in a trash where they can be restored or erased. Attachments upload and download from any page, namespaces build a page tree in the sidebar with pinned pages on top, and full-text search highlights every match. Public mode publishes a read-only knowledge base, private mode requires sign-in, and administrator and user accounts are managed in the app. Settings cover the wiki title, owner notice, privacy banner, language, timezone, light or dark template, and accent color, and every page has a print button. A desktop app keeps files on your computer and syncs with your self-hosted instance, while a REST API with Swagger documentation lets other tools read and write pages. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

"Somewhat lightweight, low-friction" is how Silicon Notes' author describes the personal knowledge base - written after DokuWiki's editor "drove me mad" and no existing wiki quite fit. The philosophy is that small frequent annoyances compound into cognitive load with no return, so everything here is optimized for frictionless daily use. Notes are written in plaintext Markdown and rendered as clean HTML with Pygments syntax highlighting for code blocks; pages get bi-directional relationships (backlinks), so the knowledge base becomes a connected web rather than a folder tree; and full-text plus title search retrieves anything fast. A table of contents lives in the left sidebar - "where it belongs" - editable while you read without scrolling away. Page history tracks revisions for auditing and rollback, JSON export/import keeps everything portable, and the mobile layout is genuinely usable. The stack is deliberately minimal: Python and Flask with Mistune for Markdown and SQLite for storage - no big frameworks, just a few small dependencies. One honest caveat: there is no built-in authentication, so deploy it behind a VPN, private network, or reverse-proxy auth layer. For a solo engineer's brain, it is exactly enough.
