$198 minus $24 leaves $174 a month, or $2,088 across a year if the workload stays where it is [17][18]. Against that sits a weekend of setup, after which the scheduled backups and the monitoring are yours to keep working [14].
What the install script leaves behind is the part worth reading [8]. Docker, Swarm mode so containers come back when they die, Traefik out front, and a small database holding Dokploy's own state [9]. Set that against the hand-rolled attempt and the substitutions map one to one: Traefik takes over the hand-written Nginx block and the Certbot run, Swarm takes over PM2 [3][9]. The author's note that he had configured every one of those by hand the first time and got each wrong at least once is the honest version of the pitch [10].
Dokploy publishes a 2GB minimum, and his verdict is that it is technically true and practically a trap, because the build runs on the machine it deploys to [5]. The failure is quiet. On the $12 droplet the log stopped part way through with no error, and twenty minutes went into blaming the Dockerfile before the kernel's memory kill surfaced [6]. So the tier that works costs twice the tier that died [19], and the figure to hold against the managed invoice is $24 for the 4GB box, on Ubuntu 24.04, on the grounds that boring is correct here [7].
Then the config line. The firewall opens 22, 80, 443 and 3000 [11], and 3000 is where the dashboard lives [13]. Keys are in and password login is off [11], which settles SSH. Within a day the auth log held thousands of failed attempts against a box nobody had been told about [12]. The writeup never says what, if anything, guards the control plane sitting on port 3000.
The transfer test is whether a peak build and the database both fit in 4GB next to the running app. His do [1][5]. That is one box, one region, no standby, and a build that competes with production for memory every time you push. Priced purely on the droplet, DigitalOcean was not the cheapest option available and he says so, choosing it because his other projects were already there [15].
It's the accounting that generalises, and it applies whichever tool executes it. Once the invoice is broken into features you can name [2], the question stops being whether servers are hard and becomes which of those features you would be rebuilding by hand, which is exactly what four days with PM2 and Certbot answered badly: deploying from a phone over SSH, with no build history and no rollback plan beyond hoping it would work [3][4].
