I think it's good that PieFed is so small, that means they can move faster and innovate more without fearing that things will break for thousands of people. I think it's good that a project like PieFed can try things and see what works and sticks and this is then a good indicator for projects like Lemmy to copy what is good and leave out what is not good.

Probably app support. If Lemmy didn’t have wefwef/voyager during the API debacle of 2023, I probably would not have stuck around. The default UI is terrible for mobile.
The default UI is terrible for mobile.
I'm definitely in the minority, but I prefer the Web UI on mobile to apps
I also like the default UI, even if it's not the prettiest. But for mindless scrolling I prefer Voyager.
Apps make or break those platforms. Lemmy apps are way better than what Mastodon has for example (but I have to tip my hat to Phanpy). We got really lucky that Lemmy exploded in popularity due to Reddit API changes which meant many app developers gave Lemmy a shot. I probably wouldn’t use Lemmy so much if Voyager didn’t fill the hole Apollo left in my heart.
Phanpy is phenomenal and fixes a lot of the problems Mastodon and all microblogging platforms have.
Mona is also a good app.
Voyager is so polished, it elevates the whole experience.
We have data on what it costs to run a sizeable instance of Lemmy and it's not a lot. How does Piefed compare? Anyone starting an instance who envisions it growing large has to contend with this question. Currently it seems it's got a bit under 1000 users across under 10 servers.
There are now sizeable communities run on Lemmy instances that are reinforced by network effects. There needs to be a significant reason for them to migrate. To that point, the collective project is building communities away from corporate power, not software. The software is a tool to facilitate that. Lemmy has worked well so far in this regard. If someone can show that Piefed can work better and not cost significantly more, it'll probably get adopted for new communities. If the difference is drastic, we may even see migrations from Lemmy.
We won't 100% know the answer to that until we get there. But in 2025 fear of a lack of CPU cores is NOT what keeps me awake at night.
Early performance results are positive. Check these links out:

There are many many ways to ruin web app performance and choice of backend language is not really a big one. It's what you do with it that counts.
https://piefed.social/ is running on a low end VPS which costs $7.50 per month. Load average is about 1.45 during the busiest part of the day. Most of the load is caused by federating with lemmy.world and that won't increase as more users come on board.
PieFed is also really efficient with storage. After 16 months of operation, subscribed to every popular community, the piefed.social DB is 30 GB and the media storage is 28 GB. A Lemmy instance would be 10x that. I haven't bothered to add S3 storage code because we just don't need it (yet).
Anyway, all this focus on costs and downsides is only half the coin. There are massive benefits that come from using Python:
- Easy and fun
- Fast development velocity
- Huge amounts of developers know Python
- Extensive and mature libraries with good documentation
- Good readability
- Cross-platform without re-compiling
For a FOSS project where volunteer contributions from people play a big part these things are really important. There are many ways a project can fail (not just technical reasons but social & governance too) and running out of CPU is way way down on the list.
These performance results are only from the browser side, but dont cover server performance. The database for lemmy.ml is 60 GB, and that is with 6 years of history. Not sure where your 10x claim comes from. The lemmy.ml server costs 70 Euros per month and doesnt have much loa, with almost 10 times as many active users.

I know the 0.03€ per user per month has been known for a while, but it still impresses me.
using Python
Full disclosure: I like Python a lot and have written a lot of it.
That said, if not for my recent work experiences, I would be absolutely horrified at the idea of using Python for such a project. Between the type system and being interpreted, the performance and runtime issues are pretty painful. That and the historical greater dependence on external application servers really makes Python-based services something that really sucks to administer.
However, as I noted, I have also recently seen Python performing far faster than it has any right to with highly-optimized use of multi-processing and offloading the server stuff to Go.
I think I'm going to have to take a look at Piefed source this weekend.

All your saying is, it looks better. I am not using any Lemmy webfrontend, I've always been using the apps that are available, many of which are absolutely polished.
There's more than that.
Stuff like feeds, topics and better onboarding.

I never knew what it was because I'm a bit desensitised to knew apps / app names.
Edit: using https://phtn.app/ has made Lemmy extremely pleasant to use too. I haven't had a better experience on any platform.
My biggest issue with Piefed is how much space the UI uses. Last I checked it didn't have a "compact mode" like current Lemmy or Alexandrite. Browsing communities is also a bit awkward since it shows you so many topics without a way to sort or remove them.
That is exactly the main reason I created my own theme, but yeah there should be a official compact theme, especially for the mobile phone.

Why aren't we suggesting Mbin over Lemmy, actually? Because it seems like it has the same options. And Mbin even has an app (not just the PWA function)!
