Hey selfhosters 👋
A few weeks ago I shared Ideon here and got great feedback that shaped a lot of what I’ve been working on since.
Since my last post here, Ideon crossed 200 stars on GitHub and I wanted to say thank you ❤. It means a lot to see people interested in what started as a side project. It motivated me to work on it literally every day since then.
For those who missed it: Ideon is a self-hosted visual workspace where you lay out everything about a project on an infinite canvas: notes, Git repos, code snippets, checklists, sketches, links and connect them together. Two containers, no external dependencies.
Since then, a lot has changed and I wanted to share an update.
Self-hosting got smoother. Docker permission issues with bind mounts are gone, build times are faster, and there’s a new GIT_ALLOWED_HOSTS env variable so you can whitelist your internal Git servers (Gitea, Forgejo, GitLab behind a VPN, etc.) without the SSRF filter blocking them.
Collaboration got real structure. There are now 4 project roles (Creator, Owner, Editor, Viewer), a Request Access workflow for private projects, and the canvas supports real-time multiplayer with conflict-free editing.
The canvas got a lot more usable. Keyboard navigation (arrow keys + vim keys), a command palette, freehand sketch blocks, drag-and-drop checklists with progress bars, markdown tables and task lists, emoji reactions on blocks, edge labels, and a bunch of stability fixes for large projects.
Where this is going next:
Right now Ideon lets you see your project. Git stats, issues, PRs show up on the canvas, but you can only look at them. For the v1 I want to move from visibility to control. Merge a PR from the canvas. Trigger a deployment. Restart a service. Turn the workspace into an actual cockpit where you operate your project, not just view it.
That’s the direction. Curious what this community thinks about it.
If you tried it and hit something rough, or if you’ve been waiting to try it, now’s a good time. Feedback always welcome.
two containers
Good luck, but I’m out.
bro, there’s one container for the app, and one container for postgres, the all doesn’t surpass 500 Mo of RAM… where do you except to host the database ? Sorry If I sound a bit rude but you can always edit the .yaml manually to only launch the app, the app will use SQLite then, or configure an external postgres database via env :)
This looks seriously amazing, I’m totally gonna host this for myself tonight. And as someone else said, try to move off of GitHub if possible!
THANKS ! and yes from what I’ve read, I am strongly considering it
This is a neat project. You should consider moving this to Codeberg, though. Github is a serious risk for FOSS projects.
Thank you, I am not aware of the risk with GitHub, can you tell me more?
There’s many good articles out there if you have the time. It boils down to stolen code, forced identification and enshittification.

You’re not wrong, but unfortunately for now github is the best for reach and discovery, which may be important for these kind of projects.
You’re awesome !
Wait… there’s no LLM/AI nonsensical utter bloody-void horrible mess?
My gracious holy smokes… THANK YOU!!! Thank you… from the very depths of my heart… and soul… for making something that is actually important… that is for human…Thank you, dear @expyth0n@lemmy.world for the marvel… art… you do…
There’s still belief in effort, education, human, art… in the purpose…
This is honestly one of the kindest messages I’ve received. THANKS ❤.
I’m just tired of seeing every project full of soulless AI slop for fame.
I try to build things with intention, even if it’s not the “trend”, I prefer to stay aligned with what suits me :)
No, I said I wasn’t playing with my server this weekend. I promised my wife. She’ll get pissed.
I guess I’m getting a divorce 🤣
Edit: 2 things
1.- that demo looks awesome. Thank you so much.
2.- can you suggest an easy way to migrate all my Obsidian data to Ideon please? Otherwise, I’m looking at a few (using the word ‘few’ very lightly here) hours of copy/paste.
Okay, I’m not taking responsibility for any divorces caused by Ideon 😹

Really glad you liked the demo though, that means a lot. I honestly didn’t expect people to seriously consider moving their whole setup.
For Obsidian migration, yes, I can absolutely make it happen. But I want to be transparent, it’ll take a bit of time to build something clean and reliable :)
Take your time. It’s by no means a deal breaker. I’m sucked into self-hosting deep enough that I can keep what’s in Obsidian right now while using Ideon, and just wait until I can move it to Ideon. It wouldn’t be the first time I have 2 services running in parallel until I figure out which one I’m keeping. Hell, I did that for almost a year when I was in Joplin and then decided to move to Obsidian.
As for the divorce, I don’t think it’s going to happen any time soon. She wanted to catch-up on Solo Leveling, so I joined her. I’ll spin up the server tomorrow when she leaves for work 🤣
Maybe I’m blind, but is there a docker composed YAML?
Would like to reverse proxy this into my VPS.
I might be stupid, but I didn’t want to run the install script because I try and run everything via compose files in Komodo.
I don’t know if this helps, but this is what my compose looks like:
(Side note, I just put the ENV values directly into the compose. I know this is not recommended, so I put the values to use if you actually mount the env_file like you’re supposed to. )services: # ------- Ideon-App ------- ideon-app: image: ghcr.io/3xpyth0n/ideon:latest container_name: ideon-app # If you want to do it correctly, mount the ENV_FILE # env_file: # - ${ENV_FILE:-.env} # If you want to do it janky, follow me environment: #If you mount a ENV_File, only PUID and PGID are needed below. PUID: 1000 # Optional: User ID for file ownership (default: 1001) PGID: 1000 # Optional: Group ID for file ownership (default: 1001) # From the ENV_FILE: APP_PORT: 3001 # Host port to expose the app (container listens on 3000) # I had Homepage on port 3000 so I moved Ideon to 3001 APP_URL: http://mymachinesip:3001/ # Public base URL of the app (used for invitations and SSO auth) TIMEZONE: UTC # Canonical timezone for server logs ONLY ### Database #SQLITE_PATH=./storage/dev.db # Override SQLite path (optional) # Note: PostgreSQL variables are not required in "development" mode, SQLite is used automatically (storage/dev.db).

I wanted to use it locally for some low level importance notes before I try to move more over and set it up with an actual mounted env file on a VPS.
My only thought so far is that its not the greatest on mobile, but I’m really not certain what that would even look like. (Edit: I’m dumb. I didn’t close the sidebar. It actually looks pretty good on mobile. Ignore me.)
yeah obviously that’s ok, glad you like it, and yes, didn’t really focus on a mobile mode yet, but it’s coming soon if demand were to grow
Honestly, I was surprised at how well it works on mobile, once I collapsed the sidebar. (Thats my fault for not doing that earlier when I was trying it: I feel pretty silly)
So far I’m genuinely loving it! I certainly hope the demand grows, cause its pretty fucking good so far. Thank you so much!
of course, there is better, i made an installer that does everything for you, downloads the yaml, the env.example creates secrets, prompts for hostname, port, etc. and finally starts the containers, of course you still have the choice to say no at every step, or edit the .env manually, everything is in the repo (I tried to post it here but seems to be blocked by lemmy’s firewall :-/ )
This looks incredible! Kind of bummed I didn’t notice this when you shared it last time, as I’ve been trying to find essentially literally this.
I’m also on agreement with everyone else, its refreshing to see something non-AI
Ah man, that actually means a lot. Timing is everything I guess 😅
Very interesting, forwarding this to several groups who seem stuck with Miro boards.
Thanks 🙌, appreciate it !
Already selfhosting it. Thank you so much for your time and effort <3
YAY ! The goat 😆
The demo is sweet bro. Seriously, looks good. I’m going to have to check this out.
Looks quite impressive!
Not sure if useful for me though.
Thanks, there’s a demo if you want to try, just in case
I just wanted to try the demo linked on your Github and I couldn’t login with the provided username and password even though I copy and pasted them.
how ? I just tried right now and it works, do you get an error or sum ?
Now it worked for me too. I don’t know, it told me that the username or password is wrong.
#GoodFirstIssue 😹
Refreshingly not an ai made thing…
Nothing bad about using ai but
Yes, of course, but I just think that when you make something and especially invite people to use it, you have to at least know what you’re doing, cuz I see a lot of people who promote open source, who want to contribute and so on, saying it’s free stuff, that’s okay, But throw something with AI, you don’t even know WTH you’re doing and you ask people to install your thing ? That’s where I really lose it tbh.
I am with you my friend, all the way
