๐ I am excited to announce that I am now officially a Core Developer at @coolifyio! ๐ Coolify has become my passion and I'm committed to taking it further than ever imagined. I am excited to shape the future of Coolify together with the community.
It is Monday and I have exciting news! ๐
Over the past weeks/months, I realized that @coolifyio is growing on me. ๐
So thanks to the support of the community, sponsors, and cloud users, Coolify now have its first paid core contributor. It's unbelievable, right? It certainly feels that way to me!
Please join me in welcoming @peaklabs_dev! ๐
What's even more incredible is that I wasn't even searching for someone. He simply began contributing useful PRs for free and showed me how he can do things. Nice.
This is the way.

The biggest reason @coolifyio keeps winning is the team that @heyandras has assembled + the autonomy he has given us!
The team is free to be as creative, as flexible, as pushy, or as relaxed as they want to be while having full control over their work!
The only condition is doing right by the users, and I think we are!

I will be eternally grateful to Andras. His kindness and patience make him truly one of the best human beings out there, and he gave me a lot of freedom, understanding and so much more...
Lately, I've been unsure about a lot of things, like failing to meet my own goals and not getting rid of certain issues, which has created a bit of doubt.
I am currently doing some experiments to regain confidence, try new things, eliminate some of my personal issues, get back into routines, and test out directions.
For the past few weeks, I have started rebuilding my life. Not always successfully, but I'm working on it. I'm working out regularly to get my energy back, I've finally completed some things I always wanted/ needed to do, and I've started a new hobby. As for a very long time there was only work, which made every day blend together into one big blur that I can barely remember.
I received a lot of concerns about v5 about: "why it takes so long" or "why you hype it as there is nothing usable yet.
Partly they are right as I planned to make the first beta in a few months, and it is more than a year now.
I planned v5 to be an experimental (tech, business, and money-wise) as we are making something special in a way that it will be insanely good for hosting stuffs - a real cloud feeling but with your own servers.
That is why I asked @peaklabs_dev to help me. He worked on it full-time, made lots of plans, but unfortunately he burned out in the process - currently recovering, which is why he is silent for a few weeks.
I could say that I lost thousands of dollars in this experiment, because we still do not have beta, but I see it in another way.
Someone and their family lived happily from this experiment, of course, I did not want Peak to burn out in the process. ๐
So in the last weeks, I sat down and planned how we should do v5 from scratch , and in a week, I achieved almost an alpha/beta-ready version.
In technical details, we planned v5 to be a new app - you install it on a server, it can connect to v4, and you can migrate your apps one-by-one. But I did not like this plan, as I do not want that much manual work on the users, even though it will be fully automated.
So instead, it will come to your v4 instance in a /v5 URL, and then I can extend v4 with all the stuffs needed to migrate your app - v5 will have direct DB access to v4 stuffs, and the migration will have even less friction.
I am hyped for v5. It will be cool, and it will be very useful.
Oh, and also, I made Jean, Shoutrrr (well, @AdityaTripathiD did it, but I added a few commits), and 10k+ commits to Coolify v4 - doing everyday business stuff, hiring another person, etc.
So I did lots of things in the meantime.
So I am sorry that it takes so long. I try to make it available faster, because you (Coolify users) deserve it.
You changed my (and other's) life.๐

First donation is up, just gave $2,000 to @heyandras to support open source alternatives to Codex App and Claude Desktop ๐ซก
Also pumped that this can help with Coolify, the coolest open source hosting option for people exiting platforms like Vercel
Cutting this off now. Too lazy to filter replies so I'll assume all 737 are cancellations.
That's $7,370 I have to donate to open source.
What projects should I consider? ๐

It's been a while. Some thoughts about the last couple of months.
I have a great blessing and a big curse at the same time. I want to be one of the greats. I don't just want to make software, I want to make the greatest software ever.
In an age where AI code and slop dominate and slowly turn all software into shit, destroying the future stability, usability, and quality of software, this matters. But on the other hand, it feels like driving with the handbrakes on because everybody else is shipping full-on products with millions of lines of code in a week.
For a few months now, I've been wanting to launch more products, build Coolify v5, and move faster while still progressing in life and learning new things. Instead of progressing, I've been getting slower, more tired, and for weeks now more and more stressed, always feeling like I'm falling further and further behind.
At first I thought the reason was just that I want to do too many things in life. While that's true to some extent, it isn't the full story.
The real issue is energy. To get more of it I started sleeping more, but I still felt tired every day. The actual problem was that I've been neglecting walks and workouts for months because I wanted to focus on work and ship more, but that was the biggest mistake I could have made. Energy vanishes and everything slows down with it.
Everybody told me so, I know. But the world we live in makes it so easy to get comfortable. Every time one small goal is reached, it widens and 50 new ones appear, never really living the current moment, always chasing the next thing, trying so hard to move faster that everything else gets skipped.
So this week I'll focus on building new habits, doing regular workouts, and organizing the 1000s of TODOs for my upcoming product launches, Coolify v5, and more, so I can hopefully work my way out of this vicious circle I've been stuck in for the last few months.

Opened 1 PR that adds inactivity management (users and teams) which will be needed during the v4 to v5 upgrade
โ
Opened 1 PR with super clean email templates and a command to send the v4 to v5 upgrade maintenance notification
โ
Started benchmarking and testing compression and the standardized backup on a real server
โ Tried to create realistic compression comparisons but failed because my test file was generated poorly (volume too small, all random, then 50% random...)
โ
Merged 2 PRs that fix 2 bugs into next
โ
Provided a lot of support on Discord

)
๐๏ธ PeakOSS
โ
Did a lot of research about existing file signing tools and checked for ways to improve them
โ
Did a lot of research about cryptography in Rust and Zig
โ
Did a lot of additional research into post-quantum cryptography especially in Rust

Continued my backup PR development and finalized the new Postgres backup and restore commands
โ
Finished reading over 4+ Postgres docs pages covering all backup options and which newly available options we should also include
โ
Read over all MySQL and MariaDB docs pages for all backup options and which new options we should use for all future backups, and it is a mess
โ Tried to figure out 1 clean format to use for MySQL and MariaDB to cleanly backup and restore all new backups and there is no clean way lol
โ
Found the cause for a long-standing local development issue where apt and apk package downloads where failing - its was my VPN
โ
Did a lot more research and planning about how to cleanly and consistently name and store the new backups with the signature and manifest file

โ
Improved my backup PR by switching zstd compression to level 12 and also making it use all threads, which is much faster and provides even more compression
โ
Did a lot of docs reading to improve backup and restore commands further
โ
Did a lot of research about compression, how it works, and which is the best option (xz, zstd, or one of the many others)
โ
Did a lot of initial research about backup file encryption and how to handle it in v5, making sure it is easily compatible with the new backup format of v4
โ
Did a lot of research on backup signing and backup file checksum verification for tamper-resistant, verifiable backups which are even verifiable outside of Coolify
โ
Made a full implementation plan for implementing signing for all future v4 backups (makes a lot of sense now so v5 can support signed backups only)

Today I made massive progress on the standardization of the backup feature - some v5 code which is coming to v4 very soon.
๐จโ๐ณ Core Coolify Development
โ
Found an even better way to standardize backup formats, as I found some issues with the existing simpler backup restore commands I wanted to use.
โ
Modernized backup and restore commands a lot, most of them are now 1 line long instead of 5+ and much simpler to maintain and use.
โ
Improved the overall backup process by using parallel dumps for Postgres and also switched all backups to zstd for better compression, which compresses even faster than the currently used gzip.
โ
Improved many other little things with the current v4 backup approach after a lot of thought and research, like new backup file naming and more.
โ
Read through the full Postgres backup docs and all backup-related Postgres CLI commands to finalize and correctly modernize the backup and restore commands.
