EVONX vs Zeplin Flows

EVONX is a web-based multi-agent AI platform for changing existing software or starting an application from a plain-language request. It examines code and dependencies across frontend, backend, infrastructure, and data layers, then turns a feature, change, or fix into a technical plan. It applies the proposed code changes, tests them, and presents a running preview. Work takes place in isolated previews; changes become pull requests only after approval, and EVONX says it does not write directly to the main branch. It can coordinate work across multiple repositories while maintaining their contracts, and its documentation describes generating a working web app and API from a description. The integrations hub provides build-with guides for services including GitHub, PostgreSQL, Stripe, and OpenAI; these are not official partnerships. Customers supply credentials and keep operational ownership of external services. The free Starter plan includes 500 credits per month. Plus costs $20 a month, Pro costs $99 a month, and Enterprise has custom pricing. Heavier models and longer tasks use more credits.

Zeplin Flows helps teams map user journeys and make design intent clearer across screens. Diagrams use labels, shapes, and connectors that reposition when screens are added or removed. Teams can group screens and flows into Flow Groups and Boards, then share them through quick links. Shapes can represent actions, decisions, and branches, helping product, QA, and Support teams identify gaps and add use cases. Flows are included across plans, while Flow Boards are available on Advanced and Enterprise. The Free plan is free and includes one project, 100 screens, unlimited members, and no Flow Boards. Advanced costs $12 a month, billed annually. Zeplin offers Mac and Windows desktop apps and a web app that works on Windows, macOS, and Linux; the web app does not support uploading designs. Listed integrations include Figma, Sketch, Jira, Storybook, VS Code, Azure DevOps, Slack, Microsoft Teams, an API, and webhooks. Developer inspect view, design tokens, asset handoff, code snippets, and version history are listed.
