• (2023-03-21) Trọng Phúc Ngô: doesn't work
• (2022-09-17) Viết Đạt Lê: Doesn't work!!!
• (2021-10-01) Mario Amatucci: hello [email protected] can you add support for the https://plantuml.com/mindmap-diagram ``` @startmindmap @endmindmap ``` it would be great
• (2021-09-28) Nam Tongdosa: It not works
• (2021-03-05) Florin Balanescu: Even with fiddling with the permissions and adding the @startuml in the xml file (which had to be recognized, because it was generated by staruml), the picture was broken.
• (2020-11-26) T I: Doesn't work at all. Only shows a broken image icon for any UML files (even a tiny file of only four lines except header and footer). In addition, I'm afraid it'll be a serious security pitfall to send user data to an external server if it is done without any prior permission or notification.
• (2020-08-04) Mohammad Nur: I used to love this tool, but It recently stopped working on all my machines - do not see the diagram anymore!
• (2020-07-31) Sunghee Lee: It does not work from several months ago on.I don't know how to fix it. The png or svg image cannot display in browser. Anyone know how to fix it? I can't find the answer with Googling.
• (2020-03-17) YJ Wu: I like this, but it can't work now in my chrome browser. I don't know how to fix it. the image could not display in browser and the request failed in debug mode. like this: Referrer Policy: no-referrer-when-downgrade Provisional headers are shown Sec-Fetch-Dest: empty User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36
• (2019-11-12) tolga ulas: the svg formats should be displayed in object tags otherwise embedded links are not clickable.
• (2019-07-15) Fei Wang: it is very cool, but there is a problem that the viewer will return to text for a seconds.
• (2019-06-19) Christian Wittrock: It doesn't support the newpage command
• (2019-06-18) Antoine Lefebvre: Very useful. I like that it refreshes when I save updates to the file in my text editor.
• (2019-04-17) Minh Pham: Found an issue with mindmap diagram that if the diagram is too wide (left-right) then the content from the right is cut. Otherwise, a great tool to have
• (2019-01-09) Илья Бормотов: Рендрит через раз. Чаще показывает иконку поврежденного файла.
• (2018-11-26) Wendy Lin: Every helpful plugin! Thanks!
• (2018-08-21) eiji: UMLの表示幅が大きくなってくると、ブラウザですべてを表示できなくなる。 scaleで調整するとなんとか収まることがあるが、なにかと不便。。
• (2018-02-04) christophe lachenal: vraiment très pratique !
• (2018-01-29) Long Hà: it doesn't work
• (2017-04-18) DaeYoung Ryu: Wow.!! greate!
• (2016-06-07) Rex Luo: If the UML file is complicated, then UML diagram can't be display completely.
• (2016-04-26) Brad Anderson: It would not parse the preprocessors '!include...' Couldn't use it.
• (2016-03-31) Jim Brennan: I have been using this for a while thinking it was completely generated locally. Now that I understand it sends the data to the cloud, without warning, I have downgrade to 3 stars because I cannot use it. It would have been 5 stars if it was all locally generated.
• (2016-03-01) Zhen Wang: hopeful
• (2016-02-16) Konstantin Suslin: русский алфавит формируется кракозябрами
• (2016-01-04) Jo Wang: I like this tool very much, and it did help me a lot. the reason why I gave 4 stars other than 5 is that the Chinese font used in this tool SUCKS, which makes the EXTREMELY UGLY pics whenever Chinese character is involved.
• (2015-09-19) Jacob Ras: Excellent. Now I can use Notepad++ to create the UML files while viewing them in Chrome on another screen. +1 for auto-refreshing the files when they're saved!
• (2015-06-26) Vladimir Alexiev: Great. Can you please also handle @startditaa, which makes DITAA ascii art diagrams?
• (2015-06-17) Jörn Guy Süß: I wish the plantuml version was more up-to-date or there were instructions on how to update it. Otherwise, this is one of the most effective tools I have in my shed.
• (2015-03-17) Leo Ko: Очень удобно для предпросмотра редактируемых диаграмм в текстовом редакторе (тот же vim + plantuml viewer == love)
• (2015-01-12) Johnny Lam: I found some issues that didn't work with the extension: 1. First line of file MUST be @startuml, if it was a comment (or set of comments) then it would fail. 2. Pre-Processor directives didn't work. E.g. !include filename 3. Not sure how to update the plantuml.jar file when updates occur. Would have a higher rating otherwise.
• (2014-12-28) Jeff Horsager: I love this tool. Online and off.
• (2014-11-26) Sergey Rodionov: Просо замечательное расширение!!! Давно пользуюсь UML Plant, но как часто бывает - на рабочих компах ничего ставить нельзя (ни Graphviz, ни Java) и это расширение отлично решает эту проблему! Всем советую! Спасибо!
• (2014-09-02) Thomas Berglund: Great lightweight tool for drawing UML diagrams fast and easy, using simple scripts.
• (2014-06-20) Patrice FERLET: Congrats, really nice, usefull, and simple.

• (2023-08-21, v:1.2) Mario Liulión: CORS error
  There is a CORS error. Console shows this message over and over again: ``` Access to XMLHttpRequest at 'file:///home/my_file.plantuml?t=1692659961261' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, isolated-app, chrome-extension, chrome, https, chrome-untrusted. content-script.js:75 GET file:///home/my_file.plantuml?t=1692659961261 net::ERR_FAILED update @ content-script.js:75 Show less ``` I'm using a local server: ```sh java -jar ~/Downloads/plantuml.jar -picoweb ``` This PlantUML support for Visual Studio Code (https://github.com/qjebbs/vscode-plantuml) works fine with the same server, so it isn't the problem. By the way, were is the git repo of the extension? Thx
• (2021-02-25, v:1.2) Matti Purojärvi: Does not generate a full diagram
  I have 110 steps, but only 44 are used for generating a diagram. Why?
• (2021-01-04, v:1.2) Oleg Lapchynskyi: SVG enable
  accordingly to plugin description: ## History 1.2 - Added option to change type (PNG/SVG/TXT/None). my question: how to enable SVG to be the default image format for plugin output?
• (2020-05-28, v:1.2) Ibai Usubiaga: Calls to www.plantuml.com to render image are done in plain text
  Hi, When you try to render a diagram the plugin is doing a plain HTTP request to the remote plantuml servers. Although the server url can be edited in the plugin, I think the default option should be to use HTTPS due to user privacy and confidentiality.
• (2020-03-08, v:1.2) Kishore Vanapalli: the plantuml chrome plugin has stopped working recently
  Is this a known issue?
• (2019-09-17, v:1.2) Umang Mehta: how increase size (length)
  When i open uml file, i am not able to see full pic - it is getting trimmed from right side. I think i need to increase size like they explain in Cutoff UML: export PLANTUML_LIMIT_SIZE=8192 http://plantuml.com/faq but I am not able to see different after making above changes.

• (2019-02-04, v:1.2) Pavel Sosin: PlantUML is not rendered
  I've created PlantUML sequence diagram using Gizmo Plugin for Chrome but when I'm trying to preview UML diagram file is not rendered, only text itself is displayed. My file is stored in the google drive and accessible via link https://drive.google.com/open?id=1SmQcJS4R-xAbJ7TJF2rEruGzNAey-FcEGLKrqTrDKe4 and shared with everybody who get the link above. The Plant UML viewer icon is displayed on the Chrome ribbon and plugin has access to Google docs site. Chrome version is 7.0. I installed Plant UML viewer from Google WebStore.
• (2018-07-24, v:1.2) Gotlib Gotlib: Значок не активен
  Расширение не показывается активным значком, файл диаграммы открывается как текст
• (2018-06-07, v:1.2) Rui Li: Is "!include" supported?
  My team is starting to use a custom skin to unify the look and feel of everyone's diagram, using syntact like "!include ..\..\someskin.txt" . It works perfectly in the editor (IntelliJ). But somehow in the plugin it says "Syntax Error?". Is "!include" supported? Or there is some trick on how to use it? Thanks.
• (2018-04-06, v:1.2) hi dev i want a link
  i want a link in text
• (2017-06-08, v:1.2) Abhishek Rai: Image cropped
  I have a big sequence diagram which i want on one page. The Chrome plugin is cropping the image beyond certain length and height.
• (2017-04-03, v:1.2) Mindaugas B: Links not working
  Hi, thanks for this wonderful plugin! There is a nice feature of PlantUML which allows you to create links and tooltips in diagrams, making objects clickable, for example: @startuml class Class1 [[www.google.com{{Click here}}]] @enduml For some reason links do not work in diagrams generated via this plugin (directly). However if I save an SVG diagram to file via "Save as..", then open it again via browser from local filesystem, links actually DO work. Scratching my head..
• (2016-10-05, v:1.2) Hamza Hydri Syed: Diagrams not loading on Chrome
  The plugin was working fine until yesterday, now it works fine with saved UMLs. But new or updated UMLs are not loading on Chrome.
• (2016-08-09, v:1.2) Unable to save picture
  Thanks for this great plugin, I love it and makes my work as a Requirements Engineer much easier and faster! :) Unfortunately currently I got the problem I cannot save the rendered pictures anymore. I created some Mocks with salt. There are no issues while rendering them, but when I try to save them, there is no reaction by the browser. May this issue is caused by the filename? I realized the filename contains the whole picture as a hex code. May you change the default-name value for saving to "plantuml.png"? Many Thanks for your help. Regards
