Have you ever used a device so much that you assume that this is an open source? It was with more than one app in this list. They were independent and god-friend, sometimes even on Gitab. But under the hood, they were closed down. Easy to remember – until you look close.
Open source does not necessarily mean free. This means that the source code is publicly available, and based on the license, you may be allowed to inspect, replace, and be rearranged. Think about Linux, Firefox, or Blender.
But many modern apps blur that line. They provide free access, developer-friendly features, or an open vib, but the code has been locked. I believed that some of these apps were also open, just because they had github repos or felt. It turns out, this is not always the case. There are seven apps that seem open, but they are not.

Visual studio code
When i started using for the first time Versus codeI really thought it was an open source. It was fast, flexible, and even had its code on Github. But here is the catch: The version you get from Microsoft’s website have been issued under the “Microsoft Software License”. This includes restrictions not found in telemetry, branding and open-source codebase.
That open-source base is “called”Code – OSS“Also created by Microsoft, and is available under MIT license on Github. So when the code is open, the product is not downloaded mostly. This distinction matters if you care for transparency or want to re-prepare a revised version. For a clean, telemetry-free experience, you can switch. Veskodium,
This is one of the clear examples of how an app can be made at an open source, but not open sources.

This IDE really made me a better programmer
An IDE to rule all of them. You won’t want to use anything else.

Github
This caught me from the guard. If I thought Github Is the house for open-source projects, it should also be an open source, right? No. Github is a completely closed platform. You cannot self-pronounce it, inspect how it works, or forms its top based on their infrastructure. It is easy to forget that it enables open source, it does not follow the same model.
Forgago And Gitia If you ever need a completely open option then there are solid options. Just know that these options are self-host, so you will need to manage your own example. This is very good for control, but it takes a little setup.

Obesidian
Obesidian It seems that the kind of equipment will build an open-source enthusiast: Markdown support, local storage, tons plugins. I used it for months, before feeling that it was owned. There is no access to the source code, and its powerful sinks and publishing features are closed behind a pewall. If you are looking for something more transparent with similar features, Logseq And Zetal There are great open options that actually let you see what is under the hood.

What is Markdown, and how do you use it?
Markdown is a simple syntax that forms web pages — and it is much easier to learn and use compared to HTML.

Strings
Strings A strong developer community is an open API and custom bots. It seems open, but it is not. I remember one day trying to find a source code for a customer and try to kill a wall; Everything was closed. If the discord ever closes or changes the direction, there is no way to thorn or host your own version. Rebellion If you care about decentralization or data ownership then it may be better.

perception
Perception Flexibility and greasy design make it a head in my workflow. For a long time, I assumed something that was powerful and dear in the Dev communities, to be open. This is not. The codebase is closed, the platform is only cloud, and you are locked in their ecosystem. There is no self-hosted version or real transparency. If you want an open, self-conscious version of that note-database hybrid, then a tool Appfow Comes near.

Fig
Designers like figs, and for good reasons. It is fast, collaborative and easy to use. But this is a completely closed source. You cannot host your own version, you cannot fork the tool, and you are dependent on their server. When Adobe announced a plan to acquire figs, there was a major conversation about the need for an open design tool. The deal was eventually abandoned after the regulator pushback at the end of 2023, but showed that figs are still owned. If you are looking for something open, Penpot Right now one of the best options is, and it is making stable progress.

Postman
When I first started looking at API in painting, Postman It was the app that I kept using people. It was everywhere: Video, Tutorial, Walkthrrow. It felt like a main tool in the ecosystem, so I assumed that it was an open source. But this is not. The core app is owned, and when it provides team cooperation and many features, you cannot modify it or host your own version. If you are looking for a transparent, open-source option that works in the browser, Hoppscotch It is worth checking out.
So why do people keep doing it wrong? Because these devices feel open. They are often free to use, at least at a basic level, popular with developers, and integrated with open ecosystems. But there is no open access equal to free access. Without access to open licensing and source code, they are still closed platforms, no matter how much they welcome. I have fallen more than once for that confusion.
