Getting Tiny Crash Fighters to Actually Work
I spent about three weeks trying to get Tiny Crash Fighters running on a standard Linux VM without hitting some obscure dependency chain that nobody documents properly. The thing is, most people download the package and just expect it to work out of the box, but there are a few steps you need to take to avoid wasting your time. First, you will want to grab the latest release from their GitHub repository at https://github.com/tinycrashfighters/tcf/releases/latest. The tarball usually comes with a prebuilt binary for x86_64 Linux, which is fine if you are on a recent Ubuntu or Debian system. If you are on anything older than 2022, you may need to compile from source, and that is where things get messy.
Tiny Crash Fighters Installation and First Run
Extract the archive, then navigate into the directory and run the setup script with elevated permissions. Yes, it asks for sudo. The program needs to bind to port 443 and 8080 by default, so unless you change the configuration, you are going to hit permission denied errors if you do not run it as root or with appropriate capabilities. The config file lives at /etc/tcf/config.yaml after installation. Open it and look for the bind_address field. By default it is set to 0.0.0.0, which means it listens on all interfaces. If you only need local access, change it to 127.0.0.1. I learned this the hard way when I left it on the default setting and had my server showing up on public scanners within twelve hours. Not fun. Start the service with systemctl start tinycrashfighters and check the logs immediately. Something like journalctl -u tinycrashfighters -f will show you what is happening in real time. You should see a message confirming the websocket listener came up, followed by the HTTP API endpoint initialization.
Common Pitfalls and Edge Cases
Here is what I wish someone had told me upfront. The default SSL certificate expires after 90 days because it generates a self-signed cert on first run. This is fine for testing, but if you plan to expose this to anyone beyond localhost, you need to swap in a proper certificate. Let's Encrypt works, but the tcf package does not include the renewal hook automatically. You have to write it yourself or use a separate certbot integration. Another thing that catches people out is the database backend. The program defaults to SQLite, which is perfectly adequate for small deployments up to maybe fifty concurrent connections. Once you push past that, you start seeing lock contention on write operations, and the latency spikes become noticeable. I moved one of my instances to PostgreSQL around month four, and write throughput improved by about six times. The migration itself is straightforward though. Export with tcf db dump, create the new database, then import. Memory usage is also something to watch. The program can balloon to nearly two hundred megabytes under moderate load if you do not tune the connection pool settings. Look at the max_idle_connections parameter in the config. Setting it to something reasonable like 20 instead of leaving it at the default often brings the memory footprint down to around one hundred thirty megabytes. The tradeoff is slightly slower query times during peak load, but for most setups that difference is imperceptible.

Performance Tweaks That Actually Matter
If you are running this on a VPS with limited resources, enable request compression. It is turned off by default, which is odd because it cuts response sizes by roughly sixty percent on JSON-heavy endpoints. Add compression: true to your config and restart. Also, disable the debug logger in production. The default log level outputs everything including request headers and response bodies for failed queries. It fills up disk space fast and slows things down. Set log_level: warn instead. I had a case once where a misconfigured instance wrote about eight gigabytes of logs per day. Not ideal. The WebSocket server has a built-in ping/pong timeout. If you are proxying through Cloudflare or some other CDN, make sure the idle timeout on your proxy is longer than the tcf ping interval, which defaults to sixty seconds. I ran into a situation where connections were dropping every ninety seconds because my nginx upstream was killing idle connections before the application could respond to the ping. Setting proxy_read_timeout 120s fixed it immediately.
When It Simply Does Not Work
Let me be clear about where Tiny Crash Fighters falls apart. It does not support Windows Server editions past 2019, and the ARM64 builds are community maintained with occasional breakage on newer kernel versions. If you are running a custom Linux kernel with strict seccomp profiles, you may need to add exceptions for certain socket operations, or the process will just segfault on startup without a useful error message. There is also no native clustering mode. If you need horizontal scaling, you are on your own to set up a reverse proxy with sticky sessions or use the built-in replication feature, which only works reliably between identical version numbers. Mixing versions causes data corruption in the session store, something I discovered after trying to upgrade one node while leaving another behind. If your use case requires high availability with automatic failover, you might be better served looking at something like Nginx Proxy Manager or Traefik paired with a proper container orchestration layer. Tiny Crash Fighters is solid for single-node deployments and development environments, but it was never designed to be the backbone of a multi-region infrastructure.
