What if you just don't care about which provider and model you use between prompts? You start with Claude, then Anthropic decides to make some bad moves, as usual and then you can change to OpenAI and continue where you were left. (coming in next version of Jean, releasing tomorrow morning)

Thank you QuickSrv for sponsoring Coolify! 💜

It took years in Coolify to go from the huge menu (first image) on mobile to a responsive, better for mobile view (second / third image). Your app is fine without being responsive / mobile first.

Never thought Coolify would be this "big" that SSO would be a feature, but I guess it is good. 😅 (coming in 4.2)

🚢 Coolify v4.1.2 Bunch of security, bug fixes, service template fixes and UI/UX improvements. Happy deploying 🫰 (4.2 will have at least 3 bigger features updates.) github.com/coollabsio/...

🛠️ Jean 0.1.52 - The most important part of this release is the improved system prompts (general and PR release prompts) and the opinionated plugins. Make sure you install them, they are soooo good.

I made enough $ in May 2026 to live happily with my family. Now let's continue to work, make something useful and make the world a bit better place somehow.

🚢 Jean v0.1.51, fixes, Opus 4.8, improvements, workwork.

Shipping day: #3 MaxIO 0.4.0 - added encryption support (SSE-S3, SSE-C), public bucket access and improved the embedded UI a bit + a bunch more things. Currently Github Actions is down (again) so the release will be triggered later on.

Shipping day: #2 Jean v1.0.50 with bunch of fixes, new models (like Composer 2.5), improvements, etc.

Shipping day: #1 First release is a brand new docs based on Fumadocs. Very shiny, very new, very good, very fuma, very cool.

Thank you Siebert Group for sponsoring @coolify.io! 💜 They are helping companies to boost their productivity with AI agents, like Siemens, Vodafone, Allianz, Deutsche Bank 🤯 (the grid on the landing page is getting full even for the HUGE sponsors. BIG sponsors grid is already busy a bit 😅)

Let's end the week with 4 horrors. 😭 Chromium, Megalodon, Drupal and bind9

🛠️ Coolify 4.1 released - Railpack (beta) - Instance level MCP so you can talk to your Coolify instance from any AI. - Improved diff tracking so if you change a config, you will see what is changed exactly before you redeploy. And a lots of fixes, other smaller features. Happy update 🫰

It looks like i have to post about securityhorrors.com everyday. we have rss feed as well: securityhorrors.com/rss.xml

I tested and deployed the new core infrastructure, and then I migrated the HTTP servers to it. @coolify.io Cloud has been running on them since 1 PM. (You can see that is way faster if you open the UI) Tomorrow, I will continue with the job servers. I will make a post with the technical details.

🛠️ I am making a new library/service/idk (soon opensource) for our upcoming apps. I am testing rust + svelte, fully embedded apps for months and they work quite well. they are small, single binary, memory safety, fast and easy to host or even run it on your computer.

🛠️ Jean v0.1.49 Most important thing is that Jean has a local MCP server, so it can call itself. Example prompt: auto-investigate the latest 5 Github issues in separate worktrees And it will spawn 5 worktrees and starts auto-investigating them. 🤯

TL;DR: So I am leveling up as a businessman and I hired another dev to help me make more community-requested apps for you! 🫡 We have a page ideas.coollabs.io for your ideas but it is very simple atm. It will be improved overtime. Not TL;DR (with lessons learned):

I am announcing that I will make an announcement on Monday.

🚨 New day, new security issue: Node-IPC Supply Chain Attack, Linux Kernel, PostgreSQL securityhorrors.com

Shadow, one of my mods, casually made a web based network architecture designer, just to have nice images for our documentation updates. wtf (Oh and its free and opensource) github.com/ShadowArcan...

We could extract their system prompt and more funny things. Research purposes only! 🧐 They running their agents as root, what could possibly go wrong. "User goal: generate $100 ChatGPT subscription" "Submit at least 5 PRs for bounties" wtf

The bots are now implementing fake bounty issues in brainfuck programming language.

We added custom system prompts to see what these bots are. Openclaw mentioned after a few minutes.

🚨 New day, new security issue: Nginx securityhorrors.com/all/nginx-t...

🛠️ Jean could call itself from the next version (through local MCP). You can automate a lot of your workflows with this. For example, "get the atest 5 Github issues and start investigating them in separate worktrees" and voila. MAGIC

Security horrors, because why not. You can sub to rss feed. securityhorrors.com

We have a leaderboard and an official JSON file so you can ban them as well easily. clankers-leaderboard.pages.dev

🚀 Jean v0.1.48, too many features, fixes and improvements, read the changelog pls 😅 github.com/coollabsio/...

We made a fake repo with fake bounties, and the bots are applying fake PRs, so we know who is fake, and we can ban them from the Coolify repo. IQ over 1000

🛠️ Improving the configuration change view, so now you can check what has changed since the last successful deployment.

You could have pure terminal as a "session" in Jean. You can use terminal based CLI's if you want, but still you can get all magical things from Jean.

Over 10000. 🤯 Thank you everyone. Now lets work work.

🐰 Integrated CodeRabbit CLI into the next version of Jean with a TON of new features, UI/UX revamps.

What if we should have a real opensource email client that looks cool and just works? UI inspired by Coolify and mail0.

Okay chat, we have a "problem". Just got sponsored by @cursor_ai as well (thank you 💜), so I have 4 subs (forgot that I have Copilot as well). WHAT TO DO NOW?! I cannot work more than 24/7.

Thank you Capture Page for sponsoring Coolify.io! 💜 Fast & Reliable Screenshot API for Developers.

Opus 4.7 & GPT 5.5 are the first models that can do a collapsible navbar from the current layout of Coolify properly. I am doing very scientific measurements here.

Thank you Lumadocs for sponsoring @coolify.io 💜 We have a bunch of VPS providers as sponsors now! So incredible to see!

I love the project linking feature in @jean_build. I linked together the landing page, the docs and the actual app of Coolify and if I add a new sponsor it knows and changes everything with one prompt.

What if we had a compact mode in Jean? No hundreds of lines when Mr. AI is working, you probably won’t read it while it’s running - I usually dont. 😅 It’s just making noise. After a long planning session I just yolo.

It is still surreal - after 4 years - to see blog post about Coolify. I cannot get used to it. 😅 It is unbelievable that with one idea and a lot of work, you can change your life. Thank you again SerpAPI for sponsoring Coolify. 💜 (links for the blog posts below!)

New serverlesshorror story: $36k bill on Cloudflare. serverlesshorrors.com/all/cloudfl...

I let Claude update my GitHub profile page, what do you think? (the commits per hour per day tells everything about entrepreneurship in general. I left 9-5 to work 24/7) github.com/andrasbacsai

🚀 Jean 0.1.47 - Embedded browser - Terminal reconnection - Opus 4.7 1M (I missed to add it before 😅) - And lots of fixes. Happy vibing 🫰 github.com/coollabsio/...

🛠️ Integrated MCP server in Coolify v4.1 - basic, read-only tools for now. Inspired by @stumasondev work on github.com/StuMason/co... work. Thank you! 💜

I made enough $ in April 2026 to live happily with my family. Now let's continue to work, make something useful and make the world a bit better place somehow.

Finally releasing v4.0 of @coolify.io. It was long overdue because we have been in beta for a long time. Thousands of companies and people have been using Coolify in production for 1-2 years. Of course, this does not mean it has no bugs, it has many, but we fix them every day.

New profile pic, but old me, just have a moustache IRL.
