Show HN: Hob - Open-source, on device alternative to Claude Cowork and ChatGPT

So there are a zillion of these, including ones that do what yours does. But that being said, I'm going to always upvote every single one of them because this is better and more important that what the big companies are doing across the board.

Thank you! Would love to hear which ones you've used. Working with local files without anything going to the cloud was the main thing I wanted. I tried Jan, OpenWork, Chatbox and Lobe, and couldn't get that working well in any of them. If there's one I missed it would be great to check it out!!

Definitely check out Osaurus for macOS and Windows. Heavily privacy focused with e2ee iOS and iPadOS tethers.

In PasClaw, I specifically built it to do local embedding and other local only functionality. Whether it works well or not yet is another story.

Have you tried Open WebUI? It doesn't determine which model works best for your hardware, but it otherwise has a very large feature set with a large community, and runs offline by default. Geared more for technical users, however.

It feels like the last mile is so long in this space. I'm a SWE with a ton of experience and I still haven't gotten over the decision paralysis of figuring out which model to run locally, and which inference platform should I use, and will my M1 Macbook Pro actually run anything well enough to be useful, and on and on.

It's kind of embarrassing to admit, but having something Just Work(tm) makes getting started so much easier.

Shouldn’t be embarrassing to admit.

It’s a huge new subject area and it’s completely exhausting to learn. I still feel like a total novice.

I have an M1 Max (more memory bandwidth) so I am not sure how much advice I can give about models, but I would suggest maybe trying the new LFM2.5-24B-A2B. It’s surprisingly good. If you want to mess about with multimodal work, Gemma 4 12B is really impressive. (I mostly use Muse Glimmer but it might be rather slow on an M1 Pro)

If you want to have the space to learn the terminology, tinker with what you can control etc., then you have three easy options: LM Studio, Unsloth Desktop or the llama.cpp native Mac app. But don’t get put off by the llama.cpp command line; most of these tools are running it behind the scenes, and most entries on Hugging Face have recommended parameters.

MLX is an option but so far I haven’t found it to have an edge over simple GGUF on Metal on the M1 at least; it seems it might have more advantages on the later M series chips, but it is usually slower for me.

I have explored running OpenCode inside a VM (you can “remote into it” from the OpenCode GUi desktop app). You might want to look at Paseo, which can do a similar thing but with many more coding agents.

I am quite intrigued by Osaurus; on macOS 26 and up it looks like it will manage a container for you.

You might also want to look at Orchard. Not done this myself yet but I can see the appeal.

I am an experienced web dev in my fifties. Six months ago everything I have written above would have been total gibberish to me. Learning some of the open weights stuff has made me feel much less helpless than I think I might if I just developed a Claude dependency. Nothing matters more to me than grasping the fundamentals.

I still don’t really use LLMs for hands-off coding. But I have found that a local LLM can be a useful sidekick; even at the most basic level it’s a better Google that remembers the context of queries.

Orca works great.

I am using Hermes and I did not try charts, but the rest it can do with ease. And I use DeepSeek flash API as a driver most of the time.
Fwiw, I'm liking the koboldcpp "ecosystem", including koboldlite; basically it's letting me try a little of everything, though there may be something of a "jack of all trades master of none" thing going on. But it has these nice little presets for, e.g. llms, voice, music, images, a "chatgpt"-esque interface, etc.

Did you happen to try bionic?

laughing_snyder | 11 hours ago

This doesn't seem to be open source? They link a GitHub account, but I don't see the repo for this tool.

universenz | 11 hours ago

Correct, they’re closed source and you can’t opt out of analytics

laughing_snyder | 11 hours ago

Looks great. One thing I am missing is the ability to change the installation directory for the models. For space reasons, I want them to be on a different partition.

[OP] pancomplex | 11 hours ago

Good call. Are you on PC/Mac/Linux?

laughing_snyder | 11 hours ago

Linux. I saw you support HOB_USER_DATA, which is great. But I want my config to remain in .config/Hob and only move the models (or whatever else needs lots of space) to another disk/directory.

Edit: Actually I think HOB_USER_DATA is enough for my use case.

Why does it have to be JS? With all this AI, why can't we ship native apps.

[OP] pancomplex | 11 hours ago

It's still pretty tricky to do this as a solo dev to keep feature parity in my experience (fun fact, even Claude's own Desktop app is made in Electron).

That being said, majority of the heavy LLM lifting happens natively with llama.cpp :)

> Automatically finds the best open-weight model for your hardware on first install

Do you have examples of what hardware runs what models?

rhedak | 10 hours ago

I'm actually building something similar and thank you very much for sharing you gave me a few inspirations. I want mine to integrate seemlesly with an animated Ai companion (it's harder than it sounds haha). Anyways great stuff! Gave it a star.

[OP] pancomplex | 10 hours ago

Thank you. Yes please fork that's exactly why I put it out on MIT license :)

mickelsen | 10 hours ago

Haven't tried it yet, but I like that you shared your process in such an honest way, and kept it no frills, as in no LLM wall-of-text readme in the repo. Wish we could see that more often these days.

[OP] pancomplex | 9 hours ago

thank you! Haha I always make it a point these days do handwrite these things. I think everyone is tired of overly verbose perfectly written AI text.

Can we configure it to use local models but in LAN? Like Ollama or Strata.

[OP] pancomplex | 8 hours ago

So basically allow you to point the LLM to a hosted model on your local network if I understand correctly?

atmanactive | 6 hours ago

Yes.

What made you change it's name from 'Garth'?

[OP] pancomplex | 7 hours ago

I went back and forth with my coworkers on the naming and we essentially voted on Hob vs Garth. Vote came to Hob. Do you prefer Garth?

I did not enjoy that there was no way for it to clean up the 18GB of models it installed after I determined it was not really usable for any real work.

[OP] pancomplex | 5 hours ago

Sorry about that. I’ll make sure it cleans up after itself in the next update. What was the main issue you ran into?
The models are really dumb, mainly.

With the raise of AI, I believe: open-source and local software's will be on the rise, but with the open-source environment there is a real security issues that rise.

Never the less, really appreciate your contribution
