# How to use libpod for custom/derivative projects
libpod today is a Golang library and a CLI. The choice of interface you make has advantages and disadvantages.
Running as a subprocess
---
Advantages:
- Many commands output JSON
- Works with languages other than Golang
- Easy to get started
Disadvantages:
- Error handling is harder
- May be slower
- Can't hook into or control low-level things like how images are pulled
Vendoring into a Go project
---
Advantages:
- Significant power and control
Disadvantages:
- You are now on the hook for container runtime security updates (partially, `runc`/`crun` are separate)
- Binary size
- Potential skew between multiple libpod versions operating on the same storage can cause problems
Varlink
---
Some code exists for this; splits the difference. Future uncertain.
Making the choice
---
A good question to ask first is: Do you want users to be able to use `podman` to manipulate the containers created by your project?
If so, that makes it more likely that you want to run `podman` as a subprocess. If you want a separate image store and a fundamentally
different experience; if what you're doing with containers is quite different from those created by the `podman` CLI,
that may drive you towards vendoring.
