Cryptpad might be something for you. It has a special focus on privacy: CryptPad is a private-by-design alternative to popular office tools and cloud services. All the content stored on CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys (not even us). It offers most of the usual office-type apps ...

I've started to collect some alternatives here, as this is a re-occuring issue at F-Droid (which does not permit Firebase or other proprietary components). Gotify is an open-source push notification server (you can explore its Swagger API doc) Server Sent Events (SSE) are used by some apps like Tutanota XMPP is used by several apps (of course including XMPP ...

We have setup Microsofts product line for our clients to replace Access. You could either utilize sharepoint, or a better option visually, the Common Data Service. It is not too expensive depending on how many users you have. I believe $35/m for one user to set up everything, and then at least $4 for each user that needs access to this data to make edits. ...

It's expensive, but a custom web application with a robust database backend may be what you need to meet your fairly specific needs, as well as the scale of your data. The Access database could be migrated to SQL Server using SQL Server Migration Assistant for Access and the business logic would have to be replicated in a web app (the obvious choice being a ....

Userbase is a great open source solution: https://userbase.com/ This post has a bunch of other options that look viable: https://medium.com/visualdevspace/9-awesome-tools-you-can-use-to-build-membership-sites-e173e912c8a7 Headless CMSs like Ghost might offer something similar: https://ghost.org/vs/memberful/

There are plenty of such tools. Just take a look at https://en.wikipedia.org/wiki/List_of_wiki_software or at this structured comparison of various Wikis. I personally use TiddlyWiki for my purposes, but many other tools will do.

An app rather than an online service would be Audacity which is free, Open Source and available for Windows, macOS, GNU/Linux and other operating systems. The process is simple: Create a new (mono) track: Tracks->Add New->Mono Generate your 1st tone: Generate->Tone select frequency & duration. Repeat for Second Tone Mix the two: Tracks->Mix-&...

It's feasible to incorporate a generator and scanner into a site using HTML5 and javascript. If you're interested in using a commercial product, the LEADTOOLS SDK may be sufficient.

I found this which works, thought I'd share it. It doesn't let you share Postgres DBs, only SQLite though, but it's perfect for running basic queries, and is free.  https://sqliteonline.com/

Maybe the software from FreedomBox would be interesting for you to examine, they share files locally with Samba, which can also be accessed from the outside.

The zoo of awesome backend frameworks that would perfectly suit your use case is huge. Thus, what defines the choice is not so much the frameworks themselves but the availability of suitably trained/skilled people to you. See what skills you can get, and from there choose the tools.

Looking at your requirements, there are some apps that are worth looking at: Photoprism, demo is here. Piwigo, demo is here. Photonix I suggest trying out their demos, so that you can decide what works best for you. There is also a comprehensive list here with other suggestions. Edit: A more recent list of photo and video galleries.

Not a web app but Gnuplot should do the trick. According to the program website " Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. " If i understand correctly, you want something like the last figure of this link. You can easily find tutorials on how to use the app.

As already mentioned, Pocket is indeed a good app. Although I have recently replaced Pocket for Raindrop and won't be looking back. It works like a charm and will probably meet all your needs. Raindrop checks the bolded, important items off your list, and even more. Below just an overview of how many options you have for sorting the bookmarks. Additionally,...

Cryptpad by XWiki calls itself the "zero-knowledge cloud". It is more a replacement for encrypted pads, etherpads and Google Docs than for a wiki, but you can use it with some wiki-like features if you have enough discipline (e.g. to cross-link related documents and archive the documents you need) I'm using it with a few different groups and people ...
