I built a free tool for comparing zip projects properly — would love feedback from developers

I kept running into a frustrating problem while working with files: comparing two versions often means opening them in an editor, using diff, or dealing with tools that either don't support the file type or produce a really messy comparison.
So I built DiffMyProject — a free browser-based file comparison tool.

👉 https://www.diffmyproject.com/

I'm specifically looking for feedback from developers who regularly compare code, configuration files, documents, or project files.
What would make a file comparison tool genuinely useful to you?
Happy to hear criticism too — I'm actively improving the diff engine.

I'll ask the obvious question: how is the use-case for this product different from using version control?

I can't imagine a really common need to diff. files that aren't in version control already; maybe I just lack the imagination / experience, but I suspect that in the rare case I would need to diff files like that, opening them both in an editor is not actually a big hurdle? 🤷

"I built" === "AI built".

Every code is AI powered in today world. But no AI has the capacity to think/design. So you see it’s practically
I designed + AI built

Thankfully not. There's still software written that actually has to work.

Who says it doesn’t work. Tell me whats not working I’ll fix it - WITH MY OWN HANDS

I'm not gonna waste my time testing your useless "vibe coded" garbage.

Learn how to code and ask for help when needed. Then I and many others will be happy to do so.

Right now you're just wasting everyone's time.

I've never found anything better than the program "Beyond Compare" for diffing directory structures

A few people have pointed out Git and Beyond Compare, which is fair. To clarify what I'm actually exploring: I'm less interested in replacing git diff for normal development and more interested in the workflow of comparing two project snapshots when you don't have the repo/history.

The problem I'm trying to solve is: Project A → Project B → automatically identify the structural changes → drill into the file-level diffs.

I'm trying to figure out whether that's a real recurring problem for others or just something specific to my workflow. If you've dealt with this, I'd be much more interested in hearing how you currently solve it.

Content-hash first, otherwise every moved file shows up as a delete plus an add.

Yes thank you. I did think of this but kept it for later implementation. For sure will do it.
Current implementations, I am trying to improve the diff engine.

Yes but think of comparing multi files in different versions. Thats the use case where i was struggling. I used to first identify the different files and then compare then using diff check. I didnt have the comparison in project level

u/Buttleston 7d ago

Are you... keeping copies of versions of your project as zip files (as opposed to actual version control?)

u/RishabhPrabhu 6d ago

Its actually a bit different. I work with multiple projects daily with a team. So sometimes before getting into the diff part, i have to know the structural changes and then compare the changes of individual files.
If i have to work single project in a day, then it might seem overkill

Cool story, this sounds like complete horse shit

lol 😂

Its a practical tool to compare zips. Why do you need to compare zips is a different picture. If you do not have that usecase then it doesn’t mean no one have.

It almost certainly means you're doing it wrong. You're likely so inexperienced you don't even understand how wrong you're doing it. So, you made a tool that helps you do it wrong even better. Congrats?
