They are genuinely good, within limits
There is a tendency among developers to dismiss connector platforms. That is wrong: for simple flows they are faster to build, cheaper to start and maintainable by non-developers, which is a real advantage.
The question is not whether to use them but when to stop.
Where they are the right answer
- Two systems, a handful of steps, modest volume
- A flow you want to test before committing to a build
- Something a non-technical person needs to own and adjust
- Connecting tools that both have official connectors
- Anything where a failure is an inconvenience rather than a problem
The four signals you have outgrown them
- Per-task cost. Pricing that was trivial at a hundred runs a month is material at fifty thousand.
- Conditional complexity. Once there are branches inside branches, the visual editor becomes harder to reason about than code.
- Error handling. When you need retries, partial failure handling and reprocessing, you are asking for capabilities these platforms provide thinly.
- Business criticality. If an hour of silent failure costs real money, you need monitoring and testing that a flow builder does not offer.
The tell we hear most: “nobody is quite sure what that zap does any more, but things break when we turn it off.” That is a system that has outgrown its tooling.
The hybrid that usually wins
Keep connector platforms for the long tail of small integrations, and build the two or three flows that carry real volume or real consequence. Most mature setups look like this.
It also avoids the trap of a single enormous custom platform that only one supplier understands.
Migrating without a big-bang rewrite
Move one flow at a time, starting with the highest volume or highest consequence. Run both in parallel briefly, compare outputs, then retire the original.
Document what each flow does before migrating. Frequently the documentation exercise reveals that two flows overlap or that one is no longer needed at all.
