Show HN: Ultra-portable Gantt chart tool for very regulated environments

#1

Post by aerugo_ »

I work for government agency with a lot of security considerations. We can't install anything and using public webapps is out of the question. Going through clearance or procurement to buy or install something is a pain.

I needed a project management tool, and what we had on offer was too clunky and old. I built SimpleGantt to be ultra lightweight and portable. It's one HTML, one Javascript and one CSS file. Each project is saved into a single .yaml file.

If you have a SharePoint environment you can "host" it by uploading the repo to SharePoint after renaming simplegantt.html to simplegantt.aspx. That allows anyone with access to open the tool by simply having the URL.

Try it at: https://aerugo.github.io/simplegantt/simplegantt

This is a couple of days of tinkering, and mostly exists to keep me from going crazy while managing projects with lots of deadlines and dependencies, so don't expect much. But another person in the same position, finding this might lead to calmer days.

Thank you very much for this project, not only because it looks nice but also to have created with a long lost spirit: "I do something nice for myself and I share it with the world" open source, and doing something straight simple with dependency!

I wish more things are released like that.

Also your tool might be very useful because there isn't a good Gantt tool that is lightweight anymore, i search for one recently and my only solution in the end was to use an excel template...

My 2 feedbacks if you are interested: - it is annoying to have the "category" required to create a task. Maybe you could create a task with an "undefined" category if none provided? - a great feature would be to be able to export the result output or view in a PNG picture or SVG.

I've had a fair bit of success making miniature "local HTML with embedded JS, no external resources" apps like this. You just have a single file that runs in the browser like an Excel macro but much more secure. You can have the JS and CSS embedded within the HTML file too, which makes it even easier.

I'd use a plain file picker for loading instead of the file system access API. That's even less security cross-section.

Looks pretty interesting.. Wonder if this can be done with nothing but browser, CSS, html and a JS without those extra CDNs.

For truly locked-down environments that's the way to go. You can only be sure the code will always be the same if it's 100% local and offline, or verifying signatures somehow.

You can verify signatures of JS and CSS files to make sure they are only loaded if they are exactly what you expect them to be by using the "integrity" parameter, see https://developer.mozilla.org/en-US/docs/Web/Security/Subres...

That's really nice, such a good idea.

Over the last 15 years the browser has become more and more of an application delivery platform, and that notion has caused SaaS to run basically everything.

I realised this not too long ago, and incidentally it was due to gantt software.

We, like everyone it seems, use Jira for issue tracking, but the actual roadmapping of resources and dependencies leaves a lot to be desired, tools like Microsoft Project are not only prohibitively expensive- they also don't work on MacOS.

Similar issues can be levied at Omnigraph.

Only SaaS tools like "InstaGantt" seem to fit the bill of cross-platform, lightweight and reasonably cost effective.

Note: I'm currently not using Instagantt, despite it being the closest to good I could find, because I dislike subscriptions. :(

Yeah. Guess it'll involve some trade off in terms of UI.
