The self-hosted versus SaaS debate is usually argued by people who have only lived on one side. Here is the honest ledger from both.
What SaaS does well
- Zero operations. Someone else patches, backs up, and scales it at 3 a.m.
- Instant start. Sign up and the tool is there in a minute.
- Predictable entry cost. A few dollars per user until it is not.
What SaaS costs you
- Rent that grows. Per-seat pricing taxes your success; a 20-person team pays four times what five people pay for the same bytes.
- Data on someone else’s disk. Export formats are a courtesy, not a right. Deletions and lockouts happen.
- Roadmap roulette. Features you depend on can be deprecated, paywalled, or re-priced with 30 days’ notice.
What self-hosting gives you
- Fixed cost. One server runs the app for 5 users or 50. Open-source apps like Odoo, SuiteCRM, and Grafana charge nothing per seat.
- Control. Your database, your backups, your rules. Nobody audits your usage for upsell.
- Longevity. Open-source projects survive acquisitions and pivots. The code cannot be taken away.
What self-hosting honestly costs you
Updates, security patches, backups, and monitoring are real work — a few hours a month per app if nothing goes wrong. Multiply that by five apps and it becomes a part-time job. This is the real trade-off, and pretending otherwise is how servers end up two years behind on patches.
The third option
Managed self-hosting keeps the ledger’s left column and outsources the right. With OpenSysLab, each app runs on your own private server — provisioned, updated, and backed up for you, starting at $6 a month — and the Vibe-code agent inside Open WebUI can help you configure and run the app itself. You keep the data ownership without the 3 a.m. pager duty.
