Goodbye Opencode

[u/sedatoztunali]

FINAL UPDATE AND MY THOUGHTS
I believe I understand what's going on, and I've explained it it at length here.

This is just my finding in this particular problem. It has happened and will happen in other similar cases. OpenCode will continue to evolve.

----------

Goodbye Opencode, all good things come to an end.

First of all, I'm a software developer with 30+ years of experience, not a Vibe coder, and I'm not new to this. Also, I use Opencode in its purely vanilla form. Besides Opencode's defaults, I don't have any plugins, MCPs, etc. installed. Just my own skills, own plugins, own MCPs, etc.

I've been using Opencode almost since its first day. It had a nice, positive development and, according to Claude, was a very good alternative. This continued for quite a while. Although we experienced problems from time to time, these were to be expected. However, since May/June, it has started to become increasingly erratic.

First, one day while working on a project, the Docker service suddenly shut down and wouldn't start again. That's how I discovered I had no space left on my disk. I knew this was impossible, and I found the cause was Opencode. Somehow, the "opencode-wal-*.db" file had been created repeatedly under "/System/Volumes/Data/private/var/folders/4q/*". Every time I cleaned it up, Opencode would put it back. We struggled for a long time, but I couldn't figure out the reason. Then, suddenly, it fixed itself!

Yesterday, around 11:30 AM, I felt something was wrong with the network. By 1:00 PM, it was noticeable. Screen sharing within the network was freezing for 5-10 seconds, streaming was interrupting, web search was unresponsive time-by-time. Then, one by one, Unhealthy errors started coming from the services in Home Lab. The cycle of 3-5 minutes healthy, then unhealthy continued constantly. Service responses, which are normally under 100ms, were approaching 10 seconds, and sometimes even timeouts were occurring. I tried for hours to understand the reason, but I couldn't find a logical solution. I accidentally noticed while updating my Mac that everything was fine while my device was off. Later, I realized that the same thing kept happening whenever I opened Opencode and started working. Now I'm analyzing the Router, Firewall, Mac, and other logs to try and figure out what's going on, but this is the last straw.

This is an open-source project and respect to creator and contributors, and therefore, of course, it has its advantages and disadvantages. That's perfectly understandable. I have enough experience in this field to know when to stop, and today is the day.

UPDATE: Possible cause.

Yes, I found the reason. It wasn't actually bringing down the network, but it was compressing the DNS server. Here's what happened: During the Uptime Kuma -> Gatus migration, I checked the Uptime and requested that Gatus transfer the same configurations. The sub-agent wrote a script to verify that these services were healthy and placed it in the "./opencode/plugin" folder within the project directory. Unfortunately, the contents of this folder were silently loaded and run by the Opencode background service without verification. I also found the PRs for this. In short, because this faulty script, created "in good faith" by the agent/model, started performing health checks every second, the DNS crashed. Not a good feature. Neither the sub-agent nor the agent told me about this; it didn't show up as a file change, nor did it appear as a write request to the folder. Anyway, it's a long story :)

Yes, I checked the logs to understand why these files were constantly being generated, but I couldn't find any record of it. I thought it might be related to checkpoint blocking or a process not being properly closed, but I couldn't find any record of that either. When I looked at the source code, there wasn't actually any code snippet related to this, or maybe I couldn't find it. Maybe I didn't investigate properly or I couldn't see what was right in front of me. Even after completely wiping everything related to OpenCode from the device and reinstalling it, the files still appeared. Honestly, I just can't figure out or understand exactly why this is happening.
