At standup, a dev mentions a self-hostable, open-source workflow automation tool the team runs on their own infrastructure instead of a third-party SaaS. Which tool fits this description?
n8n is an open-source workflow automation platform that can be self-hosted on a team's own infrastructure, giving full control over data residency and deployment rather than relying entirely on a third-party SaaS vendor. This self-hosting option matters for teams with strict data governance requirements or a preference for owning their automation infrastructure. It contrasts with automation platforms that are only available as a hosted service.

During a design review, the team wants to add a custom JavaScript function node to transform data in a way the built-in nodes don't directly support. Which capability supports this?
A code node lets a builder write custom JavaScript directly within a workflow to handle a data transformation that the platform's built-in prebuilt nodes don't directly support, blending no-code convenience with the flexibility of custom code when needed. This escape hatch avoids being fully limited to whatever prebuilt nodes happen to exist. It's a notable differentiator for platforms designed to appeal to a more technical audience alongside no-code users.

In a code review, a dev configures credentials for connecting to an internal, self-hosted API that isn't a common prebuilt integration. Which capability supports this?
A generic HTTP request node with configurable custom authentication lets a workflow call any API, including an internal, self-hosted service that isn't among the platform's prebuilt integrations. This flexibility ensures the automation platform isn't limited only to popular, pre-integrated SaaS tools. It's particularly valuable for organizations automating around their own internal systems, not just external vendor products.

An incident report shows a self-hosted automation instance went down because no one was monitoring its uptime, silently breaking several dependent workflows. What practice would prevent this?
Choosing to self-host an automation platform means taking on the same operational responsibility as any other production service, including uptime monitoring and alerting, rather than relying on a vendor's own infrastructure team. Skipping this monitoring is how a self-hosted instance's downtime silently breaks dependent workflows without anyone noticing promptly. This operational tradeoff is a core consideration when choosing self-hosting over a managed SaaS alternative.

During a PR review, a teammate asks why the team chose a self-hostable automation platform instead of a purely SaaS-only alternative. What is the reasoning?
A purely SaaS-only platform is operated entirely by the vendor, offering convenience but less control over data residency and infrastructure, while self-hosting gives a team full control at the cost of taking on the operational burden of running and maintaining it themselves. This tradeoff is a deliberate choice teams make based on their compliance needs, technical capacity, and appetite for operational responsibility. Neither option is universally correct independent of those factors.
