No-code Workflow Tools Initiated Integrations
Workato
The early winners in integrations were the companies that turned API plumbing into something an ops manager could assemble in a browser. Workato, Zapier, and Tray started with internal workflows, like moving a new hire from an HR system into email, payroll, and ticketing tools, then expanded outward once software vendors wanted the same drag and drop logic for customer facing integrations with OAuth and embedded setup flows.
-
This first wave was built for internal automation, not product engineering. The core user was a business or IT operator wiring apps together with blocks for triggers, actions, and field mapping, which is why ease of use became the category defining feature.
-
The category later split in two. Workato and Tray kept pushing upmarket into enterprise automation, while newer embedded and native integration vendors focused on software companies that need deeper, customer facing integrations with more code level control.
-
That split shows up in scale and buyers. Zapier reached an estimated $310M revenue in 2023 with a broad self serve automation footprint, Workato reached about $150M with enterprise accounts, and Tray reached about $70M with low code enterprise workflows.
The market is moving from simple app to app automation toward a stack with separate layers for internal workflows, embedded integrations, and developer infrastructure. That favors Workato as long as it keeps its no code ease while adding the governance, depth, and enterprise coverage needed to beat MuleSoft on large automation programs.
