Should I self-host Day One?
Memos booted in seconds and journaling in it is genuinely pleasant. But Day One is $6.25/mo and its apps are excellent — the math is thin and this is a category where owning the data is the real argument, not saving money. Worth it if a journal you own outlives any subscription; otherwise keep paying.
The math (nothing hidden, including your time)
| Day One (Gold) | $6.25/mo |
| VPS share + storage | −$0.30/mo |
| Your maintenance: 10 min/mo at $20/h | −$3.33/mo |
| Net saving | $2.62/mo |
| Setup: 11 min measured (one-time) | $3.67 |
| Break-even | 1.4 months |
| Markup Index (price ÷ real self-host cost) | 1.7× |
