Notea is a privacy-first, open-source note-taking application. It supports Markdown syntax, sharing, responsive and more. Notea is self-hosted, so your data is safe in your hands. In a few steps, it can be deployed to Vercel or Netlify, or even your own server via docker. Notea does not require a database. Notes are stored in AWS S3 bucket or compatible APIs. This means you can use MinIO (self-hosted), Aliyun OSS (like AWS S3) or NAS to store your data. You can publish your content to the web. With beautiful typography and new upcoming features, you can share your docs, wikis, blogs and newsletters with others using Notea.

UI and admin pages remind me of Tiddlywiki.
An open source self hosted notes and bookmarks taking web app. Looks like of like Pinterest and kind of like a kanban board. PHP, so it could be run in shared hosting.
Written as a PWA so in theory you can take it with you. Or at least the user interface, I don't know about the back-end database.
A web-based text editor for networked note-taking, self-hostable on any Git repository. Retrieve knowledge as fast as you can type with zero-latency full-text search. Make serendipitous discovery via backlink traversal. Durable knowledge preservation with plaintext and Git backend. Efficient navigation and command powered by keyboard-centeric interaction design.
High performance NLP models as a service. Pre-trained. You can upload and run your own spaCy models as well. Seems to be GPU accelerated on the back-end because they're an nVidia partner.
Named entity recognition, classification, summarization, question in context answering, sentiment analysis, part of speech tagging.
Free tier: All pre-trained models, 3 API requests per minute.
Starter tier: All pre-trained models, 15 requests per minute, $39us/month
HPI is a Python package (named my), a collection of modules for social networks (posts, comments, favorites), reading (e-books and pdfs), annotations, todos and notes, health data, location data, photos & videos, browser history and instant messaging. The package hides the gory details of locating data, parsing, error handling and caching. You simply ‘import’ your data and get to work with familiar Python types and data structures.
Manticore Search is an open-source search engine that was born in 2017 as a continuation of the famous Sphinx Search engine. We took all the best from that, significantly improved its functionality, fixed hundreds of bugs, and rewrote it almost completely internally. And left it all open-sourced! That’s what makes Manticore Search a modern, fast and light-weight full-featured search engine.
We have designed and developed Manticore to provide you with multi-functional relevant search capabilities with high performance and low resource consumption and importantly easily integrable. It doesn’t matter what environment you are using, whether it’s Windows, Linux, MacOS or Docker, you can always use Manticore Search and connect to it from different programming languages or HTTP via JSON or even using MySQL client.

Sphinx is a full-text search engine, distributed under GPL version 2. Commercial licensing (eg. for embedded use) is also available upon request.
Generally, it's a standalone search engine, meant to provide fast, size-efficient and relevant full-text search functions to other applications. Sphinx was specially designed to integrate well with SQL databases and scripting languages.
Currently built-in data source drivers support fetching data either via direct connection to MySQL, or PostgreSQL, or from a pipe in a custom XML format. Adding new drivers (eg. to natively support some other DBMS) is designed to be as easy as possible.
Search API is natively ported to PHP, Python, Perl and Ruby and also available as a pluggable MySQL storage engine. API is very lightweight so porting it to new language is known to take a few hours.
As for the name, Sphinx is an acronym which is officially decoded as SQL Phrase Index. Yes, I know about CMU's Sphinx project.
There are plugins for multiple webapps out there. I've used the Mediawiki one extensively.
This small script is a cheap and easy way to start with IoT projects. By using the great rtl_433 software and a cheap RTL-SDR receiver it will listen to all kinds of devices transmitting at the 433,92 Mhz frequency.
Quite likely it will receive information from weather stations in your area, if you don't own one, your neighbours might! It will also receive signals from remote controls that are popular to use to control the lights.
The gateway will receive information from the SDR receiver and publish them in JSON format to the topic sensors/rtl_433. (Without the slash!)
Subtopics are created from this JSON line allowing to easily subscribe to specific sensors.
Requires the rtl_433 utility as its data source.
An open-source low-code framework to build web apps, admin panels, BI dashboards, workflows, and CRUD apps with ease. Build UIs with YAML that is easy to read and write. Dynamic UIs with simple state management. Mobile friendly and responsive layouts out of the box.
jinabox.js is a lightweight, customizable set of components for querying and displaying results from Jina flows. You can use it for searching text, images, videos, audio or any kind of data with a Jina backend.
Jina is geared towards building search systems for any kind of data, including text, images, audio, video and many more. With the modular design & multi-layer abstraction, you can leverage the efficient patterns to build the system by parts, or chaining them into a Flow for an end-to-end experience. Large-scale indexing and querying of unstructured data: video, image, long/short text, music, source code, etc. Decentralized architecture from day one. Scalable & cloud-native by design: enjoy containerizing, distributing, sharding, async, REST/gRPC/WebSocket.
Self hostable?
PyWebIO provides a series of imperative functions to obtain user input and output from the browser, turning the browser into a "rich text terminal", and can be used to build simple web applications or browser-based GUI applications without needing to have knowledge of HTML and JS. PyWebIO can also be easily integrated into existing Web services. PyWebIO is very suitable for quickly building applications that do not require a complex UI.
Interact with the REPL and see things happen in a browser window.
Can work alongside other webapp frameworks in Python, like Django, Flask, and FastAPI. asyncio out of the box. Supports third-party data visualization modules, like bokeh and plotly.
Search worldwide news programmatically. Retrieve articles and breaking news headlines from news sources and blogs across the web with our JSON API. Search by topic, keyword, headline, and by site. Even lets you dig through news morgues for older articles.
Developers with free accounts get 100 searches per day, with results delayed one hour from publication.
Smashing, the spiritual successor to Dashing, is a Sinatra based framework that lets you build excellent dashboards. It looks especially great on TVs.
Written in Ruby. Has an extensive library of widgets; more can be added with SCSS, HTML, and a little Coffeescript. Has a REST API to push data to the dashboard (not pull it). Claims to have a simple DSL for accessing external data sources. Drag and drop construction. Has an extensive library of third party widgets, too.
InvenTree is an open-source Inventory Management System which provides powerful low-level stock control and part tracking. The core of the InvenTree system is a Python/Django database backend which provides an admin interface (web-based) and a JSON API for interaction with external interfaces and applications.
InvenTree is designed to be lightweight and easy to use for SME or hobbyist applications, where many existing stock management solutions are bloated and cumbersome to use. Updating stock is a single-action process and does not require a complex system of work orders or stock transactions.
Has a mobile app.
Look in https://github.com/Zeigren/inventree-docker/blob/master/inventree_vhost.conf to see how to proxy it with Nginx.
A Python module for building parsing expression grammars. Build recognizers combinatively, i.e., by plugging together discrete examples of things to look for. Very useful for command parsers.
Panoramisk is a library based on python's AsyncIO to play with Asterisk's manager.
It uses the TCP manager server to listen to events and send actions.
For basic usage, you have some examples in examples/ folder.
A self-hosted website to manage all your collections, of pretty much any kind. You can choose to share your collections with other people, while retaining full control on what they will be able to see. Other people can be invited to manage their collections independently on your server.
