Open Source vs SaaS: The Question Isn’t Which Is Better
Separate permission to use software from the responsibility to operate it, then choose the combination your team can sustain.

They describe different parts of a decision.
Open source concerns the software and the permissions its license grants. SaaS concerns how a service is delivered and operated. You can buy a hosted service based on open-source software, run open-source software yourself, or operate a mixed system.
WordPress’s GPL license and a hosting company’s service agreement answer different questions. One concerns the software; the other concerns the service you receive. WordPress licensing.
Source availability also deserves a separate label. n8n publishes source under a commercially restricted license and explicitly distinguishes its model from open source. An accessible code repository does not settle the permissions question. n8n Sustainable Use License guidance.
Price the work someone has to do.
| Operating job | Managed service | Your own installation |
|---|---|---|
| Updates | Provider handles its service; your integrations still need attention. | Your team schedules, applies and checks changes. |
| Recovery | Provider has a process you must understand. | You maintain backups and demonstrate a restore. |
| Customization | Limited by supported settings and interfaces. | Broader options, with a larger maintenance obligation. |
| Exit | Depends on exports, contracts and proprietary behavior. | Depends on complete data, configuration and operating skills. |
A free software license does not make server administration disappear. A paid subscription does not guarantee that an export will preserve your workflow.
Use one ordinary business problem.
Imagine a small organization needs a newsletter and a contact list. A hosted service may get reliable mail moving quickly while the owner concentrates on the writing. If contacts and consent can be exported and the organization retains its domain identity, that dependency may be entirely reasonable.
Now imagine several departments need unusual access rules, integrations and long-lived records. A system the organization can inspect and adapt may earn its operating cost. The reason is the requirement—not the prestige of self-hosting.
In either case, write the recurring tasks beside a named person. “We will maintain it ourselves” is incomplete until someone has time and responsibility to do so.
Compare the next three years, not only launch day.
Create a cost sheet with setup, hosting or subscription, specialist support, staff time, integrations and exit work. Use actual quotes and your team’s estimates. Keep assumptions visible so a change in traffic, staffing or scope changes the calculation.
A simple annual model is service fees + expected operating hours × your internal hourly cost + planned specialist work. Treat that as a planning model, not a prediction. A large unknown deserves investigation rather than a conveniently low estimate.
Choose the seam you need to keep.
For many teams, the durable assets are content, customer context and the ability to move. Rent reliable operations around them. Preserve the relationships and requirements that would otherwise be expensive to reconstruct.
Before choosing either route, perform a small exit exercise: retrieve one useful record, recreate one workflow and explain the system to someone new. Read the ownership guide for the questions that make this concrete.
