Across personal mailboxes and business domains alike, Mail-Archiver captures, indexes, and preserves every incoming and outgoing email from multiple IMAP and Microsoft 365 accounts in a tamper-resistant archive. Connect standard IMAP servers, Microsoft 365 business tenants via Microsoft Graph, or personal Outlook and Hotmail accounts using OAuth2 device code flow without creating custom cloud app registrations. Scheduled background synchronization mirrors complete folder hierarchies automatically, while bulk tenant onboarding lets administrators import every active mailbox from a Microsoft 365 organization through a single configuration screen. When an important contract, invoice, or correspondence thread goes missing, the advanced search interface filters archived messages by sender, recipient, subject, date range, folder, and body text with instant HTML preview and direct attachment downloads. Users can import legacy MBox files or zipped EML archives, export selected messages or entire accounts, and run direct mailbox-to-mailbox migrations that copy folder trees between providers. Granular retention rules optionally purge aged messages from upstream mail servers to free quota while keeping local archive copies locked against manual deletion for compliance auditing. Multi-user access controls, OpenID Connect single sign-on, detailed activity audit logs, a scoped read-only REST API, and a Model Context Protocol endpoint allow both teams and AI assistants to query historical mail safely.

Feature requests, bug reports, upvotes, and a public roadmap: Astuto (Ruby on Rails backend, React frontend) gives users a Canny-style feedback portal so product decisions rest on visible demand rather than the loudest voice in the room. Feedback organizes into as many boards as you want (features, bugs, integrations), each post carrying a custom status you define - "planned," "in progress," "shipped," or whatever matches your process - and those statuses feed a public roadmap view showing users what is actually being worked on. Participation friction is adjustable at both ends: sign-in works with plain email or any OAuth2 provider, anonymous feedback can be enabled for unregistered users, and a moderation queue lets you approve posts before they appear when spam is a concern. Integration hooks are practical rather than sprawling - webhooks fire on events to connect Jira, Trello, or Slack, and a REST API manages the whole feedback space programmatically. Brand customization, an invitation system, private-site settings, and recap emails for administrators complete a deliberately minimal tool: it collects, organizes, and prioritizes feedback well, for free, forever.

Exploratory data work, teaching material, and research code all live in the same browser tab with JupyterLab, the web workspace of Project Jupyter. Notebooks combine runnable code cells, Markdown, and rich output such as images, JSON, and Vega charts, and they use the same notebook format as the classic Jupyter Notebook. Any Jupyter kernel can execute the code, so Python, R, and other languages share one interface, and code inside plain text files such as Markdown or LaTeX can be run interactively as well. Tabs and splitters arrange documents side by side, and a notebook's cell outputs can be mirrored into their own tab to build a simple dashboard with interactive controls. Code consoles serve as scratchpads linked to a notebook kernel, while full terminals run system shells such as bash on the server. A visual debugger offers breakpoints, a call stack, and a variable explorer for kernels that support the Jupyter debug protocol. Markdown, CSV, and Vega documents show a live preview as they are edited, and built-in viewers handle images, JSON, and PDF files. The Extension Manager installs themes, editors, and renderers from PyPI, and real-time collaboration becomes available by adding the jupyter-collaboration extension. Access is protected by a generated token unless a password is set. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Kurrier unifies email, calendars, contacts, and file storage in a single web interface that connects to any email provider you already use. The Next.js frontend with Nitro API worker deploys via Docker Compose on PostgreSQL and Redis, delivering a cohesive workspace where IMAP/SMTP mailboxes from Gmail, Outlook, or corporate servers sit alongside transactional providers like AWS SES, SendGrid, Mailgun, and Postmark. Automatic inbox building handles threads, attachments, sent items, and deletion sync through persistent background polling. The CalDAV backend enables full two-way calendar synchronization with iOS, macOS, Android via DAVx5, and Thunderbird, supporting event invitations, RSVP processing through the inbox, timezone-aware scheduling, and contact-aware attendee linking. CardDAV contacts sync bidirectionally across all devices with unified name, avatar, and email resolution. Kurrier Drive provides integrated file storage through WebDAV locally or S3-compatible backends for cloud storage. Multiple identities and domains let you manage several email accounts from different providers in one interface, with fast local search indexing subjects, senders, and content without dependency on external APIs. The API-first architecture exposes clean endpoints for automation and custom integrations.

Open Agent Builder delivers a visual canvas for orchestrating AI agent workflows without writing Python scripts or managing complex codebases. The React Flow-powered drag-and-drop interface supports seven node types — Agent, Scraper, Transform, If/Else, Loop, User Approval, and MCP Tool — each configurable with provider-specific settings for Anthropic Claude (Haiku 4.5 and Sonnet 4.5), OpenAI GPT-5, Groq, or any OpenAI-compatible endpoint. The LangGraph orchestration engine handles state management, conditional routing, and human-in-the-loop approval gates while Firecrawl integration converts any website into structured, LLM-ready data through scrape, crawl, and map operations. E2B sandboxed code execution powers Transform nodes for secure data manipulation without risking host system integrity. Real-time streaming updates show execution progress node-by-node as workflows run, with Convex providing reactive database synchronization for workflow state and execution history. The TypeScript-first architecture (96.8% TypeScript) built on Next.js 16 App Router with Tailwind CSS delivers a responsive interface across devices. Clerk handles multi-user authentication with JWT integration for secure workspace isolation. Deploy via npm install and environment configuration with Firecrawl, Convex, and Clerk API keys.

TencentDB Agent Memory provides a team-level memory hub that transforms AI agent conversations, documents, and codebases into four governed, shareable memory assets: Chat Memory for conversation history, Skills extracted from completed tasks, LLM-Wiki built from document ingestion, and Code-Graph generated from codebase analysis. The four-tier semantic pyramid structures long-term memory from L0 raw conversation capture through L1 episodic extraction and L2 scenario aggregation to L3 persona synthesis, enabling hierarchical drill-down via node and result references instead of flat vector recall. The Node.js Gateway sidecar handles capture, extraction, storage, recall, and pipeline scheduling through RESTful HTTP v2 endpoints on port 8420, while the Memory Proxy intercepts Anthropic-format API calls to inject team memory context into Claude Code, CodeBuddy, and other coding agents transparently. Local SQLite with the sqlite-vec extension provides the default storage backend with hybrid BM25 keyword plus vector embedding plus reciprocal rank fusion retrieval requiring zero external API dependencies. Teams manage ownership, versions, status, visibility, usage counts, and agent bindings through the Memory Hub dashboard with role-based access control separating System Admin and team-level Admin and Member permissions. Official TypeScript and Python SDKs provide programmatic access for custom framework integration beyond the built-in OpenClaw plugin and Hermes Agent adapter.

What Doodle did before ads and paywalls took over: Rallly (three L's) lets you propose a few dates, share a link, and watch an availability grid fill in - no email threads, no forced accounts, no "$6.95/month to remove ads." The availability grid makes the winning slot obvious at a glance, comments on each poll keep the "I can do Tuesday if we start late" discussion attached to the decision instead of buried in chat, and email notifications fire as votes and comments arrive. When consensus lands, finalize the winning option and everyone gets notified. The stack is modern TypeScript - Next.js, tRPC, Prisma over PostgreSQL, Tailwind - with a clean, genuinely mobile-friendly UI, dark mode, and community translations in 10+ languages. Self-hosting means unlimited polls and unlimited participants with meeting data on your server rather than a scheduling SaaS. It pairs naturally with Cal.com: Rallly answers "which time works for everyone?", Cal.com handles "book a slot on my calendar." AGPL-licensed.

Admins, supervisors, and operators each get their own screens in OpenMES, a free self-hosted manufacturing execution system for small factories. Drag work orders across weekly, daily, hourly, and monthly planner views, and any order that stock cannot cover gets flagged. Automatic scheduling drafts a feasible plan from shift calendars, maintenance, and material shortages, and nothing changes until a supervisor applies it, with undo. Work orders carry partial batches, reusable process templates, and priority scores built from customer tier, planned quantity, and hours until due, and CSV or Excel imports bulk-load orders, materials, and recipes. Operators work from touch-optimized tablet queues, where one tap starts, completes, or reports an issue, even offline, and a critical issue halts production automatically. When a machine stops, MQTT, Modbus TCP, or OPC UA signals record the downtime automatically, and the same signals drive good and reject counters and OEE. At goods-in, an inbound inspection records pass or fail criteria and a disposition such as accept, rework, scrap, or quarantine. Material lots track received and available quantities with hold and release status, and the production cost report splits each finished order into material, labor, and additional costs, with CSV export. Supervisors follow the shift on a live monitor. Webhooks, a REST API, and hook-based modules connect OpenMES to ERP systems and custom code.

Your family's shopping list, calendar, chores, meal plan, and budget share one home in OpenFamily, a self-hosted organizer that replaces subscription family apps with software you control. At the store, everyone ticks items off the same shopping list, with automatic categories, prices, reusable templates, and a store mode that groups items by category, and every phone updates instantly. At home, recurring tasks with three priority levels go to a specific family member, and in Pocket money, approved chores earn points that convert to payouts and savings goals. The calendar offers a monthly view per member, handles recurring and all-day appointments with up to five reminders each, follows Google, Outlook, or iCloud calendars by address, imports .ics files, and publishes its own iCal feed. Recipes can be found by typing the ingredients you already have, then dropped into a weekly meal plan. At month's end, the budget shows recurring income and expenses, per-category limits, charts, and a Kakeibo view. A kiosk display turns a wall tablet into a read-only board of today's schedule, meals, tasks, and who's where, alongside sticky notes from the family. Member profiles store allergies, vaccines, and emergency contacts, and parent and child roles keep the budget read-only for kids. Mealie, Tandoor, Home Assistant, Grocy, Nextcloud, and Immich connect in one click, and an optional AI assistant handles plain-sentence requests.

Archiving YouTube channels and playlists into a local media server becomes effortless with Pinchflat, a self-hosted media manager that automates downloading, naming, and organizing online video and audio libraries on disk. Instead of manually copying links into command-line downloaders, you define reusable Media Profiles with presets tailored for Plex, Jellyfin, Kodi, or raw archival storage, and then attach any number of YouTube channels or playlists as monitored sources. Fast Indexing polls RSS feeds or the YouTube API to detect newly published uploads within minutes while falling back to scheduled full scans so back-catalog videos are never missed. Granular source rules let you include or exclude YouTube Shorts and livestreams, filter titles by keyword patterns, enforce earliest upload cutoff dates, and set automatic retention windows that prune older files after a configured number of days. Built-in SponsorBlock integration marks or strips sponsor segments and embeds chapters alongside thumbnails, subtitles, and NFO metadata files so episodes appear cleanly inside your home theater library. You can also schedule Delayed Redownloads a few days after initial publication to capture higher-bitrate transcodes or crowd-sourced SponsorBlock tags, supply browser cookies for private playlists, and subscribe to any archived source in mobile podcast players through generated RSS feeds.

Built for brands that want AI search engines to quote them, GEOFlow is an open-source admin system that turns approved knowledge into reviewed articles and publishes them across every site you run. Load documents or import trusted web pages into knowledge bases that are chunked into evidence units, with optional semantic planning and vector retrieval. Combine them with title libraries (AI can draft up to 100,000 titles), keywords, images, authors, and prompts, then set a task's generation limits, cadence, and publishing scope. Chat and embedding models connect through OpenAI-compatible endpoints or native Gemini, with automatic fallback to the next model when a call fails. Each draft passes an AI quality gate that checks evidence, citations, advertising rules, and publishing context, records scores with source locations and revision advice, and holds risky articles for a human reviewer. Approved articles appear on the built-in site with SEO metadata, Open Graph, Schema, sitemaps, and llms.txt, or travel to hosted subdomain sites, GEOFlow Agent packages, WordPress through its REST API, or any HTTP endpoint. A manual publishing workbench and Chrome assistant cover platforms that need a person, while analytics track traffic, AI crawlers, and brand visibility in generative engines. An API, command-line tool, and agent skill support automation. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Controlling Klipper-powered 3D printers from a single browser workspace, Mainsail delivers a responsive web interface for monitoring print jobs, tuning kinematics, and managing multi-printer farms in real time. Makers and print farm operators monitor extruder and heated bed temperatures, fan speeds, and toolhead coordinates live on customizable dashboard layouts. An integrated file manager and syntax-highlighted editor let you upload G-Code directly from your slicer, organize print job queues, and modify Klipper configuration files (`printer.cfg`) without opening an SSH terminal. Interactive 3D visualizations render bed mesh heightmaps for first-layer leveling diagnostics alongside a real-time 3D G-Code toolpath viewer that tracks layer progress. Multi-webcam streaming, automated timelapse recording through `moonraker-timelapse`, Spoolman filament spool tracking, and mid-print object exclusion help salvage multi-part plates when a single model detaches. You can also organize parameterized Klipper macros, switch smart relays or Tasmota power plugs, and audit historical job success rates and filament consumption.

A fair-source chatbot and conversational-form builder: Typebot assembles conversations in a visual graph editor. In a visual graph editor you chain blocks from four categories: bubbles display text, images, video, audio, and embeds; inputs collect data through text fields, email, phone, buttons, picture choices, date pickers, file uploads, and Stripe payments; logic blocks handle conditional branching, variables, URL redirects, A/B testing, and custom JavaScript; integration blocks call webhooks, OpenAI, Google Sheets, Google Analytics, Meta Pixel, Zapier, Make, and Chatwoot. Build once, deploy anywhere: custom domains, WhatsApp, or embedded in any site as a container, popup, or chat bubble through a fast native JS library with no iframe and no external dependencies - plus an HTTP API for executing bots programmatically from any language. Theming covers fonts, colors, roundness, and shadows with custom CSS and reusable templates, and results arrive in real time with drop-off and completion analytics plus CSV export. Two Next.js apps (builder and viewer) self-host via Docker under the Functional Source License, which converts to Apache 2.0 after two years.

Datasette turns a database into an interactive website and JSON API, so anyone can browse, filter, and query the data without a custom backend. Point it at SQLite files and each table gets a page with sortable columns, per-column filters, full-text search where it is enabled, and facets that tally the values in a column, including array and date columns, with suggested facets surfaced automatically. Rows have their own URLs, foreign keys become links, and a row that other tables reference links to a filtered list of those records. A "View and edit SQL" link turns whatever filters you applied into an editable query, and visitors with permission can run read-only SQL with named parameters. Useful queries save as canned queries with their own URLs, and writable canned queries add forms that insert or update rows. Every page comes as JSON and as streaming CSV. A metadata file adds titles, licenses, sources, column descriptions, units, default sort orders, and hidden tables. Access rules can apply to the whole instance or a single database, table, or query. Plugins add charts, maps for latitude and longitude columns, Atom feeds, GitHub sign-in, and custom output formats. Custom templates, CSS, and static files carry your branding. SpatiaLite support adds geospatial queries, and datasette publish deploys to Google Cloud Run, Heroku, Vercel, or Fly.

BottleCRM delivers a self-hosted customer relationship management platform that unifies sales lead qualification, visual deal pipeline tracking, helpdesk ticketing, and client invoicing into one workspace. Sales representatives capture prospects through embeddable website forms or CSV imports, qualifying leads before converting them into synchronized account, contact, and opportunity records. Account executives manage visual Kanban deal boards with stage aging timers and weighted pipeline forecasting, dragging cards across qualification phases while preserving complete interaction timelines. Customer support teams handle incoming inquiries with multi-level ticket hierarchies, business-hours service level agreement clocks, automated escalations, approval workflows, and canned response macros. Billing managers generate professional quotes and invoices directly from won deals, applying customizable line-item tax rates and tracking payment statuses through customer self-service portals. Development teams connect autonomous AI agents and third-party software using personal access tokens against the documented REST API to automate data entry and workflow updates.

Wanderer provides a privacy-first alternative to AllTrails and Komoot, giving outdoor enthusiasts complete ownership of their GPS data on a self-hosted server. The platform accepts uploads in GPX, KML, FIT, and TCX formats, automatically extracting distance, elevation gain and loss, duration, and speed statistics to build a searchable trail catalogue. The built-in route planner uses the Valhalla routing engine to calculate hiking, cycling, and walking routes directly on the map, while MapLibre GL renders smooth vector tiles from OpenStreetMap data with configurable tile sources and overlay layers. Each trail supports rich metadata including difficulty ratings, categories, waypoints with descriptions, photo galleries, and summit log entries that track completion dates with optional GPS data. Meilisearch powers instant full-text search across trail names, descriptions, and tags, complemented by map-based spatial filtering and advanced date, distance, and elevation filters. The ActivityPub integration follows the same federation protocol as Mastodon, allowing users to follow explorers on other Wanderer instances and see their public trails, comments, and summit logs in a unified feed without requiring cross-instance accounts. The WASM-based plugin system enables third-party extensions for custom integrations. The Docker Compose stack runs three containers — SvelteKit frontend on port 3000, PocketBase backend with embedded SQLite, and Meilisearch — with startup completing in under 90 seconds. On RepoCloud, deploy Wanderer on a dedicated VPS with root SSH access, persistent storage for your trail database and uploaded photos, and complete control over routing, geocoding, and tile server configurations, all under the AGPL v3 license.

Toonflow, an open-source AI studio for short dramas, animated comics, and short videos, lets you plan, generate, and direct every shot as nodes on a canvas that runs on your own server. Text nodes hold the story, characters, and shot descriptions. Image generation nodes create character sheets with close-up, front, side, and back views. Video generation nodes take numbered reference images. Aspect ratio, resolution, and duration options depend on the selected model. Connectors link the nodes, so a character sheet made once is reusable in every shot. The 3D director's studio blocks a scene with camera framing, lighting, and keyframes. Export the scene as a video node. An assistant panel reads the project and reports which assets and videos have been generated. It offers next steps: generate a shot, revise a prompt, or start a new canvas. Finished images and clips preview on the canvas and download for further production work. Models come from third-party APIs, local ComfyUI workflows, or local language models. Plugins for nodes, skills, tools, and agents install from the marketplace. MCP links external tools and services. Projects, settings, and plugins live in one data directory. The interface offers 21 languages. There is no built-in login, so a firewall or an authenticating reverse proxy decides who can reach it.

Self-hosted and built around long reading, Omnivore saves articles, newsletters, and PDFs, renders web pages as clean text, remembers your place, and keeps every highlight searchable. Pages arrive from the web app's Add button or from Chrome and Firefox extensions that authenticate with an API key. Newsletters arrive through generated email addresses once an IMAP watcher or another mail bridge is set up. PDFs open in the same reader and accept highlights and notes just like articles. Labels, saved searches, and filters such as subscription:"Name" make a big library easy to slice. The RSS section follows your feeds, lets you add a story to the library or hide it, and can sort stories into topics when an OpenAI key is configured. Custom extractors scroll lazy-loaded pages, follow paginated articles, and strip pop-ups before saving. Rules trigger webhooks when pages are created or updated, which suits automatic labelling and other custom workflows. E-ink reading settings add double-tap page turns and volume-button scrolling, and Android and iOS apps sync the same library.
