Layer 3 · self-hosting reality check
What it actually takes to self-host CapRover
The docs say 1 GB. In practice you want 2 GB control node plus app memory. Here is the honest version — real requirements, real monthly cost, what you will be maintaining, and the one thing that catches people out.
Usually reached from Heroku alternatives, where CapRover is one of the picks.
Wondering whether you need to at all? Is Heroku still free? — what the free tier actually allows, and where the wall is.
| RAM — documented minimum | 1 GB |
|---|---|
| RAM — what it really needs | 2 GB control node plus app memory |
| CPU | 2 vCPU |
| Disk | 40 GB minimum |
| Monthly cost | $12–24/mo, against per-app PaaS pricing |
| Setup time | 30 minutes including the web UI |
| How you install it | one Docker command; it runs on Docker Swarm with a web dashboard and one-click app templates |
| Ongoing maintenance | Moderate. Swarm is stable but unfashionable, so community answers are thinner than for Kubernetes. |
| Where it stops scaling | Multiple nodes via Swarm, though in practice most installs are one box and stay there. |
The thing that catches people out
It is built on Docker Swarm, which Docker has effectively stopped developing. Everything works today and will keep working, but you are standardising on a platform with no roadmap. Worth knowing before you commit rather than after — if that matters to you, Dokku on plain Docker or Coolify are the safer long-term bets.
When not to self-host CapRover
You need a technology with an active future. This is a working tool on a dormant foundation: a legitimate choice made knowingly, and a bad surprise otherwise.
Every guide here carries this section. A site that only ever tells you to self-host is selling something — the useful answer is sometimes no.

Common questions
- How much RAM does CapRover actually need?
- 2 GB control node plus app memory in practice. The documented minimum is 1 GB, which is the figure at which the process starts rather than the figure at which it works under real use. 2 vCPU alongside it.
- What does self-hosting CapRover cost per month?
- $12–24/mo, against per-app PaaS pricing This is commodity VPS pricing and excludes your time, which is the larger cost for most people — budget for moderate. Swarm is stable but unfashionable, so community answers are thinner than for Kubernetes.
- How long does it take to set up CapRover?
- 30 minutes including the web UI, via one Docker command; it runs on Docker Swarm with a web dashboard and one-click app templates.
- When should I NOT self-host CapRover?
- You need a technology with an active future. This is a working tool on a dormant foundation: a legitimate choice made knowingly, and a bad surprise otherwise.
- What is the most common mistake when self-hosting CapRover?
- It is built on Docker Swarm, which Docker has effectively stopped developing. Everything works today and will keep working, but you are standardising on a platform with no roadmap.
