Pipedream and OpenAI both shut their workflow builders: build on SDKs, not visual builders
OpenAI closes Agent Builder on November 30 and Pipedream closes Workflows on March 31, 2027, while both keep the developer and agent-facing parts. The reading is that visual builder layers are losing ground as models connect directly to apps, so agencies should sell measurable outcomes and integrations built on open SDKs and APIs rather than lock their business to one builder.
