Layer 5 · self-hosting reality check
What it actually takes to self-host GIMP
The docs say 1 GB. In practice you want 4 GB for large multi-layer images. Here is the honest version — real requirements, real monthly cost, what you will be maintaining, and the one thing that catches people out.

The thing that catches people out
GIMP works in 8-bit per channel by default even though it supports higher precision, and the setting is per-image rather than global. Photographers editing raw files lose tonal information in gradients and skies without any warning that it happened. Set Image > Precision to 32-bit floating point for photo work, or accept banding you will only notice after export.
When not to self-host GIMP
Your work depends on CMYK output for print. GIMP's CMYK support is still limited and this is the honest deal-breaker for print professionals.
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.
