Flow

Flow (Flow Engineering, operated by TRC Space Ltd) is a requirements-management platform built for hardware and systems engineering teams. It centers on a Systems Graph that connects requirements, design artifacts, tests, and components, with AI agents that continuously align CAD, simulation, code, and test — automating impact analysis, budget tracking, and compliance checking. Flow supports branching and merging of requirement baselines, iterative build gates, and an integration ecosystem spanning CAD (Onshape, Fusion 360, Siemens NX), simulation (Ansys), and dev tools (GitHub, GitLab, Jira, Linear, Slack, Notion, Confluence). It is SOC 2 Type II, NIST 800-171, and ITAR/EAR aligned with self-hosted and AWS GovCloud options. A first-party API exists (referenced in the changelog) but is gated behind login with no publicly published OpenAPI or developer documentation.

Flow is profiled on the APIs.io network. Tagged areas include Company, Requirements Management, Systems Engineering, Hardware Engineering, and Product Lifecycle Management.

Flow’s developer surface includes documentation, pricing, signup flow, support, changelog, and 10 more developer resources.
