Writing docs should feel like editing a modern document, not wrangling Markdown files - CodeX Docs delivers that on Editor.js, the block-styled editor its CodeX team builds and thousands of products use. Content is composed from clean blocks (headings, lists, code, images, embeds) with a UI that reads well on both desktop and mobile, and pages render statically with human-readable, SEO-friendly URLs. Structure is free-form: pages nest to any depth, so a flat FAQ and a deep product manual coexist in one instance, and the UI tunes to fit - collapse sections, hide the sidebar. The operational footprint is deliberately tiny. No database is required: the default driver persists to a local folder, with MongoDB available when you want it, and the whole app configures through one YAML file (overridable with APP_CONFIG_ environment variables) covering title, start page, auth password, and JWT secret. Editing mode sits behind password authentication. Thoughtful extras are wired in: readers can report misprints straight to your Telegram or Slack, Hawk error tracking catches frontend and backend exceptions, and Yandex Metrica analytics is a one-line config. A ready-made Helm chart covers Kubernetes. Written in TypeScript.

Small MSPs waste thousands of dollars annually on overlapping subscriptions for documentation, ticketing, and billing tools that don't talk to each other. ITFlow replaces that fragmented stack with a unified platform where client contacts, locations, vendors, computer assets, software licenses, domains, SSL certificates, passwords, and documents all live under one roof. The AES-encrypted password vault stores credentials with organized access controls, and domain plus SSL certificate tracking generates automated renewal alerts before expiration disrupts client services. Ticketing supports creation, prioritization, assignment, and SLA tracking, with a client portal where customers submit tickets, view invoices, approve quotes, and access their own documentation independently. The accounting module covers the full lifecycle: quotes, recurring billing, expense tracking, Stripe payment processing, and financial dashboards showing revenue and outstanding balances at a glance. AI integration through Ollama, LocalAI, or ChatGPT accelerates documentation writing and ticket responses directly within the interface. The modular architecture lets you enable only what you need, sidestepping the bloat of enterprise PSA platforms designed for organizations ten times your size. With stable releases since 2025 and zero per-user licensing, ITFlow removes the escalating costs that make commercial PSA tools unsustainable for growing teams. The PHP application deploys with MariaDB and Nginx, ready for production in minutes.

Real-time collaborative Markdown behind your own firewall: HedgeDoc (formerly CodiMD, descended from HackMD's open-source edition) keeps team notes on team infrastructure. Share a note's URL and collaborators are editing together instantly - live cursors, changes appearing keystroke by keystroke - in a three-mode interface that toggles between raw Markdown, rendered preview, and side-by-side split. The Markdown dialect is extended where engineers need it: Mermaid, Graphviz, and Vega-Lite diagrams, MathJax for equations, syntax-highlighted code blocks, embedded content, and a presentation mode that turns a note into reveal.js slides with a single YAML header. A dropdown permission system controls each note - freely editable, limited to signed-in users, or locked read-only - and published notes become clean read-only pages for wider distribution. Revisions track every change with the ability to revert to any earlier version. The AGPL-3.0 codebase is light enough to run on a Raspberry Pi and deploys via Docker with PostgreSQL, MySQL, or SQLite. Authentication covers LDAP, SAML, OAuth2, and email. It deliberately stays a focused document editor - no page trees or kanban - and does that one job with excellent keyboard-first ergonomics for meeting notes, RFCs, runbooks, and shared scratchpads.
