First-generation online IDEs such as Cloud9 have paved the way towards browser-based development. To enable the glow, the extension has to modify the internal files of VS Code, so use with caution. I recently summarized this activity and diversity comparison in an article, which might be an interesting read for you: Thank you for your answers! However, if you look at the diversity, there are various parties contributing to Theia, while VS Code is mainly driven by Microsoft at the moment. Here is a presentation from last year TheiaCon about how SAP converted their solution: Too bad it is based on electron... which means huge memory and CPU consumption, like Slack or Microsoft Teams.Use browser version, it does not have any electron dependencies. I envision a trillion things that should have been, but weren't. The Theia repository contains a guide on how to include such extensions as part of the application's package.json. As outlined above, it has already been adopted by many, and we are looking forward to seeing what you will build with Theia.A 1.0 release is the perfect opportunity for a shout-out to some of the key people who have helped to make Theia what it is.There are, of course, many more, who have put their passion and time in getting Theia to where it is today. constructor(kind/name/detail/uri/range/selectionRange) name. If for any reason you can't open VS Code, you can fix the issue with a fresh install of VS Code. If you take that into account, the activity in both projects is actually on a very similar level. This can be solved by growing a massive community of extension developers, or hiring an army of developers like JetBrains, but both are extremely hard to achieve and sustain in the long run.Theia solves this problem differently by leveraging the largest and most active IDE-extension community on the planet.The VS Code team has done a great job of creating a protocol-based IDE extension model that runs all extensions in a light-weight sandbox process. That doesn't matter, imo, that it's a platform. We are excited to announce Version 1.0 of Eclipse Theia, the vendor-neutral open-source IDE platform that runs in browsers and on desktops.Theia is the first browser-based IDE platform that supports all the latest programming language smartness in a depth similar to your local IDE. 作为阿里前端委员会共建项目 KAITIAN IDE 成员之一，我有话要说。（ BY 柳千） 首先关于题目中「华为云 Cloud IDE 和 VSCode online 高度相似」这一点，事实上华为云 Cloud IDE 是基于eclipse-theia 项目搭建的在线 IDE 服务。 与 VS Code online 高度相似是因为 Theia 自身就是基于 VS Code 及其插件生态的。 VSCode is intended as the end product, a full-featured IDE that's suited for virtually any project, but cannot be customized beyond theming and extensions.Theia is not intended to be the end product. However, if you look at the diversity, there are various parties contributing to Theia, while VS Code is mainly driven by Microsoft at the moment. As a consequence, the code base of Theia is significantly smaller compared to VS Code (due to the reuse). Theia, of course, very comfortable due to it extension/plugin system and modern workspaces/build environment. What do you mean by "adopters"?I would not understand what you meant by "not so great for adopters"? But VsCode project has a lot of commits and… using Theia as a foundation for their tools.All nice and dandy but when can we hope to get a .msi / .exe package to download and put it through its paces and compare it with VSCode on the same scenarios?In GitPod Theia is really pleasant to use. Looking forward testing it more.How can I download this IDE? It is first.Secondly we benefit from everything what VS Code maintainers do. Moreover, Theia code base seems clean and well structured. Theia does provide similar UX and compatible with VS Code extensions but relies on stable components and protocols like Monaco, LSP, DAP and vscode extension api. If you just need VS Code then use it. (By the way, you can find other such contributor-friendly open-source projects at With Theia, we finally have a no-compromise, browser-based developer experience without the typical short-comings of first-generation browser IDEs. Today Theia counts 1k forks, The Theia project uses Gitpod to provide contributors and maintainers with a ready-to-code development environment. Theia natively supports the Adding this level of VS code extension support to Theia has been a lot of work and took us two years. The basic UI element is a widget which is an HTML element with lifecycle hooks. It is scalable and connects seamlessly with many source code repositories such as GitHub, Azure Repo etc. Didn't find this point in the github site.A constructive and inclusive social network. Jonas, i read your article very carefully about a week ago, you mentioned that Theia is rely on VsCode and reuse a lot, but i was a bit confused about how many commits VsCode project has, so despite Theia reuse some parts, VsCode has many improvements and bugfixes every week due to its communityWe need open source Ide for our project, that can be highly customized, and Theia seems a perfect choice.

This limitation not only affects Theia and all of its downstream adopters, but also releases based on the open-source code of VS Code, such as We encourage VS Code extension developers to push their extensions to Open VSX in addition to Microsoft's marketplace.Theia is used by TypeFox, Ericsson, RedHat, IBM and in many other organisations across the industry: Ericsson deserves an extra mention here, as they have initiated the project together with us from TypeFox and have been fully supporting the effort from the first day.We have designed Theia, so that adopters can change it in very fine-grained ways without the need to patch or fork the core project. Is a toolset not software that can be run in this context? However, keeping up with the plethora of programming languages and frameworks that modern desktop IDEs support has always been an uphill battle. The same works for code reviews, when you open a Gitpod workspace from a Pull Request.Lowering the friction for contributors has a tremendous impact as we are waking up to high-quality pull requests from new contributors daily.

There are actually 3 things.It should not be hard to leverage LSP and DAP.
