The short answer
Use a no code tool such as Zapier or Make for simple, low volume connections between popular apps. Use n8n when you want more control, more complex logic or self hosting. Use custom code when volume, reliability, data protection or complex business rules matter more than speed of setup.
How they compare
| Zapier and Make | n8n | Custom code | |
|---|---|---|---|
| Setup speed | Fastest | Fast | Slower |
| Complex logic | Limited | Good | Unlimited |
| High volume | Gets expensive | Good when self hosted | Best |
| Hosting in the EU or on your servers | Limited | Yes, self hosted | Yes |
| Version control and testing | Basic | Moderate | Full |
| Who can maintain it | Most teams | Technical teams | Developers |
When Zapier or Make is enough
If you need to push new form entries into a CRM, post a message to Slack when a deal closes or save email attachments to a drive, a no code tool is the right answer. It is quick to build, easy to change and your team can understand it.
When n8n is the better fit
n8n shines when workflows branch, loop, call AI models or need to run on your own infrastructure. Self hosting keeps data inside the EU and avoids per task pricing, which matters once volumes grow.
When custom code is worth it
Custom services make sense when the automation is core to your business: payment matching, billing, high volume messaging, or anything where a silent failure is expensive. Code can be tested, versioned, monitored and scaled like any other software, and it does not depend on the limits of a platform.
Most real systems are a mix
In practice we often combine them: n8n or Make for the glue between tools, and small custom services for the parts that need reliability or complex logic. The important thing is that every part is documented, monitored and owned by someone.
Questions to ask before you choose
- How many runs per month do you expect now, and in a year?
- Where must the data be stored and processed?
- Who will change the workflow when the process changes?
- What happens to the business if it stops for a day?
