Self-hosting in 2026: the rent-vs-own math has flipped
Containers, one-command deploys, and open licenses have collapsed the cost of running your own tools. A framework for deciding what to self-host — and what to keep renting.
A decade ago, renting SaaS was obviously correct: running software meant racking servers and paging humans. That calculus quietly died. A Docker Compose file and a $40 VPS now run what used to need an ops team, while SaaS pricing has moved the other way — per seat, per event, per evaluation, per everything.
What changed
- Deployment collapsed to a pull and a restart — containers made 'installing software' boring again
- Postgres, Redis, and ClickHouse cover almost every storage pattern a business tool needs
- Open licenses (MIT/Apache) matured from hobbyist signal to procurement requirement
- Metered SaaS pricing made bills unpredictable exactly as budgets tightened
A decision framework
Self-host when the tool is a system of record (support history, analytics, identity), when pricing is metered against your growth, or when the data is too sensitive to live in someone else's database. Keep renting when the vendor's network effect is the product (payments, email deliverability) or when the tool is genuinely undifferentiated and cheap.
The objection that survives is operations: someone must upgrade, back up, and monitor the thing. The honest answer is that operations is a purchasable, flat-priced service — which is precisely the shape of ResoluteX's managed hosting add-on. Own the software and the data; rent the labor if you want to. That's a fundamentally better bargain than renting all three forever.
